<h3 id="h-what-is-usability-testing">What is Usability Testing?</h3>



Usability testing is when people try out a product, website, or app to see how easy it is. The testing aims to identify users&#8217; issues or problems while using the product. Usability testing can help improve the overall user experience and increase customer satisfaction. 



During usability testing, participants are given specific tasks to complete while using the product. The testers observe and take notes on how the participants interact with the product, noting any areas of confusion or difficulty. 



After the testing, the results are analyzed, and changes can be made to improve the product&#8217;s usability. Usability testing can be done at any stage of the product development process, from early prototypes to finished products.



For example, a company has developed a new mobile app. Before launching it to the public, they conduct usability testing by inviting individuals to use the app and provide feedback. The testers are given specific tasks to complete, and their interactions with the app are observed and recorded. The company can make necessary changes based on feedback to improve the app&#8217;s usability and ensure a better user experience.

<h3 id="h-what-is-user-acceptance-testing">What is User Acceptance Testing?</h3>



User Acceptance Testing (UAT) is testing that end-users or customers perform to ensure that the software or application meets their specific requirements and expectations. It is usually the last testing stage before the product is released. 



During UAT, users go through required test scenarios and perform various tasks and actions to ensure the software works in different scenarios. They also report any issues or bugs they encounter during testing, and then the team works on fixing those issues.

<h2 id="h-what-is-api-performance-testing">What is API Performance Testing?</h2>



API performance testing evaluates an application programming interface (API) to assess its ability to handle high loads. Also, to maintain high-performance levels under varying conditions.



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/api-performance-testing_in-article.jpg" alt="API Performance Testing" class="wp-image-27944" width="600" height="400"/></figure></div>



Here are some key points related to API performance testing, that you know about:



<ol><li>Goal of API performance testing: API performance testing evaluates the API&#8217;s responsiveness, throughput, resource utilization, and scalability. This ensures it can meet the expected load and maintain stability and reliability.</li><li>Environment’s role in testing: Testers simulate high loads and extreme conditions to analyze the API&#8217;s performance. Tester also tests if it is scalable and optimized to handle such loads.</li><li>Various Testing methods: Testers use performance testing tools that simulate user loads, monitor network traffic, analyze response times &amp; other metrics, and identify bottlenecks.</li><li>Metrics: Testers measure the API&#8217;s performance based on various metrics, including response times, request volumes, error rates, and other characteristics associated with the application and user behavior.</li><li>Importance: API performance testing helps improve the application&#8217;s overall performance and stability.</li><li>Role of Analysis and reporting: Testers analyze API performance data and generate reports. It provides valuable insights into the API&#8217;s overall performance, identifying areas of strength and weakness.</li></ol>



<h2 id="h-why-performance-test-your-api">Why Performance Test Your API?</h2>



When learning something new, asking a &#8220;why&#8221; question is beneficial. Doing so can help to facilitate further research and understanding. Today, as we learn about API performance testing, it is essential to recognize the significance of this process.



<ol><li>It can help you identify and troubleshoot bottlenecks, discover performance issues, determine the impact of changes, and measure overall performance.</li><li>It can also help you understand how your API will handle different types of traffic. This enables you to anticipate and plan for peak loads.</li><li>By testing your API before deployment, you can ensure that your API is flexible and can handle the demands of the real world.</li></ol>



<h2 id="h-api-performance-testing-types">API Performance Testing Types</h2>



It is time to learn about the various types of API performance testing. Here we go:



<ol><li><a href="https://testsigma.com/guides/load-testing/" target="_blank" rel="noreferrer noopener">Load Testing</a>: In this testing, the maximum operating capacity of the application was identified. The testing involved analyzing the application&#8217;s performance when exposed to a specific load.</li><li>Endurance Testing: The stability and reliability of an application are set through Endurance Testing, also known as <a href="https://testsigma.com/blog/soak-testing/" target="_blank" rel="noreferrer noopener">Soak Testing</a>. It helps to determine if the application can handle continuous usage without any problems for long durations.</li><li><a href="https://testsigma.com/blog/software-stress-testing/" target="_blank" rel="noreferrer noopener">Stress Testing</a>: We understand how an application behaves when pushed further to its normal capacity by performing stress testing. It helps to identify the breaking point of an application and determine if it can handle extreme loads.</li><li>Spike Testing: This type of performance testing evaluates how an application responds when a sudden increase or decrease in user load. This often happens during promotional campaigns or holidays.</li><li><a href="https://testsigma.com/blog/volume-testing/" target="_blank" rel="noreferrer noopener">Volume Testing</a>: This type of performance testing evaluates how an application performs when large amounts of data are processed simultaneously. It can happen during data migration or bulk uploads/downloads from databases.</li></ol>



<h2 id="h-ways-of-measuring-your-api-s-performance">Ways of Measuring Your API&#8217;s Performance</h2>



API performance can be measured by:



<ul><li>Tracking response times,</li><li>Monitoring errors and latency,</li><li>Testing for scalability, and</li><li>at last, is using analytics tools to track usage.</li></ul>



Let&#8217;s have a look at these metrics briefly.



<ol><li>Response time is one of the most important metrics for measuring API performance. Because it provides insight into how quickly the API can respond to requests.</li><li>Monitoring errors and latency can also provide valuable insights into the performance of the API. Tracking errors allows testers to identify user experience issues and ensure that the API functions consistently and correctly.</li><li>Testing for scalability allows you to ensure that your API can handle increased traffic or usage without becoming overloaded. (Slowing down)</li><li>Finally, the analytics tools can track usage patterns. This helps to identify areas for improvement.</li></ol>



By utilizing these methods, you can better understand your API&#8217;s performance and make any required adjustments to improve its performance.



<h3 id="h-passive-api-monitoring">Passive API Monitoring</h3>



Passive API monitoring analyzes the network traffic and data transactions within an API to identify potential issues, bottlenecks, and security threats. Unlike active testing, passive monitoring does not involve sending traffic to the server, reducing the risk of introducing unintended consequences.



For example, One example of passive API monitoring involves using network monitoring tools to capture and analyze network traffic in real time. This approach enables testers to gather information about



<ul><li>the API&#8217;s behavior,</li><li>including the number of requests,</li><li>the response time, and</li><li>shared data.</li></ul>



Testers can use this data to identify performance issues, network lag, or other performance issues and investigate the potential causes to address them.



So if you want to ensure that your APIs are operating smoothly and efficiently, consider using passive API monitoring as part of your solution.



<h3 id="h-active-api-monitoring">Active API Monitoring</h3>



Active API monitoring sends traffic to the server to determine how it responds to different requests under different load conditions. Unlike passive monitoring, active monitoring involves



<ul><li>generating traffic by running automated tests,</li><li>simulating user behavior or scenarios, and</li><li>monitoring the results in real time.</li></ul>



It provides rich metrics on the application&#8217;s behavior and can help testers identify areas requiring detailed analysis.



Here is an example that explains Active API monitoring easily.



Let&#8217;s say you are a tester working on a <a href="https://testsigma.com/mobile-testing" target="_blank" rel="noreferrer noopener">mobile app </a>that relies heavily on an API to fetch data from an external server. You have implemented Active API monitoring to ensure the API is always available and functioning correctly. 



To do this, you have set up a monitoring system that sends ten requests to the API every second. The monitoring system checks if the API responds correctly and if the response time is within acceptable limits. 



If the monitoring system detects issues, such as the API taking too long to respond or returning errors, it immediately triggers an alert. This alert can be an email or a Slack message to the development team, notifying them of the issue. 



The testers can then investigate and fix the issue before it causes any major problems for mobile app users. This helps ensure that the app provides a seamless experience for users at a decent load, with minimal disruption caused by backend issues.



<h3 id="h-api-load-testing">API Load Testing</h3>



In software development, load tests simulate the number of users accessing a system or service. For example, load tests can be used to evaluate the performance of a website or application under different user loads. To put it in simple words,



<ul><li>API load testing ensures the API can handle the expected traffic levels during peak usage.</li><li>This helps reduce the risk of service trouble or performance degradation when the API is used in high-volume applications.</li></ul>



<h2 id="h-recommendations-for-api-performance-testing">Recommendations for API performance testing</h2>



Here are some recommendations for API performance testing that will help ensure that the APIs are reliable, responsive, and readily available.



<ol><li>Decide the testing strategy according to the type of application: Different applications require different performance levels and <a href="https://testsigma.com/blog/the-different-software-testing-types-explained/" target="_blank" rel="noreferrer noopener">testing types</a>. For example, a video streaming service may need to test against high network throughput, while a financial trading platform may need to test against low latency.</li><li>Understand the end-to-end flow of the application: This is essential to get an accurate picture of overall performance. This will help ensure no bottlenecks or disconnects along the way.</li><li>Remember the underlying technology: API performance testing can reveal issues with underlying technologies, such as hardware or software, that could affect performance. For example, if an API is running on a server with outdated hardware, it could cause slowdowns or crashes in the API.</li><li>Test in different conditions: It&#8217;s essential to test under various conditions, including network conditions (e.g., WiFi vs. cellular), device settings (e.g., tablet vs. desktop), and time of day (e.g., peak vs. off-peak).</li></ol>

<h2 id="h-test-case-design-techniques">Test Case Design Techniques<gwmw style="display:none;"><gwmw style="display:none;"></gwmw><gwmw style="display:none;"></h2>



There are tons of different ways to design your test cases. These techniques help you test all your software&#8217;s features and functions efficiently.



<h2 id="h-a-basic-example-of-test-case-design">A basic example of test case design</h2>



Let us consider any e-commerce app or website (like Amazon or Flipkart) for test case design. We want to ensure users can quickly checkout and make payments without issues. Here we test for 1 product in the cart; we will see later that this test case design technique is a boundary value analysis technique.



Title: Test that user can complete the checkout process when there is 1 item in the card. 



Description: Ensure users can checkout and make payments without issues on the website/app 



Preconditions: The user is already logged in 



Assumptions: They are using a supported device or browser to log in. 



Test Steps:



<ol><li>Open the app/website.</li><li>Go to 1 product</li><li>Add the product to the cart.</li><li>Check out the item in the cart.</li><li>Add address information for delivery</li><li>Add payment information</li><li>Complete the checkout process.</li></ol>



Expected Result: The checkout process should be complete, and the user should receive confirmation.



<h2 id="h-what-are-the-types-of-test-case-design-techniques">What are the types of test case design techniques?</h2>



These test case design techniques can be classified into three major groups:



<h3 id="h-1-specification-based-or-black-box-techniques">1. Specification-Based or Black-Box techniques</h3>



Specification-based testing, also known as black-box testing, is a testing technique that focuses on testing the software system based on its functional requirements and specifications without any knowledge about the underlying code or system structure.



<ol><li>Boundary Value Analysis (BVA) identifies errors at the input domain&#8217;s boundary. A simple example of boundary value analysis would be testing a text box that requires the user to enter a number between 1 and 10. In this case, the boundary values would be 1 and 10, and we would test with values that are just above, at, and just below these boundaries. Example: We would test with 0, 1, 2, 9, 10, and 11. We can expect that errors or defects are most likely to occur at or near the boundary values. Identifying these issues early can help prevent them from causing problems later in the software development process. </li><li>Equivalence Partitioning (EP) is another technique that helps reduce the required test cases. By partitioning test input data into classes with an equivalent number of data, one can design test cases for each class or partition. This technique ensures that one thoroughly tests the software while minimizing the required test cases. Example: If a program requires an input of numbers between 1 and 100, an EP test would include a range of values, such as 1-50 and 51-100, and numbers outside that range, such as -1 or 101. Testing one value from each partition is sufficient to test all values within that partition. </li><li><a href="https://testsigma.com/blog/decision-table-testing/" target="_blank" rel="noreferrer noopener">Decision Table Testing</a> is a technique that involves designing test cases based on decision tables formulated using different combinations of inputs and their corresponding outputs based on various conditions and scenarios sticking to other business rules. This technique ensures that we test the software thoroughly and accurately. Example: If a program offers discounts based on the type of customer and the amount spent, a decision table would list all possible combinations of customer types and the amount paid to receive a discount. Each cell in the table would specify the value that should be applied. Testers can ensure the program behaves correctly under various scenarios by testing all combinations. </li><li>Developers use State Transition Diagrams(STD) to test software with a finite number of states of different types. A set of rules that define the response to various inputs guides the transition from one state to another. This technique is handy for systems with specific workflows within them. Example: Consider an e-commerce website that has different states such as &#8220;logged out,&#8221; &#8220;logged in,&#8221; &#8220;cart empty,&#8221; &#8220;cart not empty,&#8221; and &#8220;order placed.&#8221; The transitions between the states would be triggered by login in and logout, adding the product to the cart, removing the product from the cart, proceeding to checkout, etc. An STD can help visualize and test such complex states and transitions in a system. </li><li>Use Case Testing involves designing test cases to execute different business scenarios and end-user functionalities. Example: A use case could be a &#8220;student enrolling in a course&#8221; on an academic website. Test cases would simulate the enrollment process and verify the system&#8217;s response from a student&#8217;s perspective.</li></ol>



<h3 id="h-2-structure-based-or-white-box-techniques">2. Structure-Based or White-Box techniques</h3>



Structure-based testing, also known as white-box testing, is a testing technique that involves the testing of internal structures or components of software applications. In this approach, the tests interact with the code directly. These tests are designed to ensure the code works correctly and efficiently.



<ol><li>Statement Testing and Coverage is a technique that involves executing all the executable statements in the source code at least once. We then calculate the percentage of executable statements as per the given requirement. Example: Consider code that inputs two numbers and checks if the first number is greater than or equal to the second. A statement coverage test would verify that both the &#8220;greater than&#8221; and &#8220;equal to&#8221; statements are executed during testing to ensure that all code branches are covered. </li><li>Decision Testing Coverage, also known as branch coverage, validates all the branches in the code by executing each possible branch from each decision point at least once. This helps ensure that no branch leads to unexpected application behavior. Example: If a program requires an input of a number between 1 and 100 and uses an &#8220;if/else&#8221; statement to check if the number is even, decision testing coverage would ensure that both the even and odd outcomes have been tested to confirm all possible scenarios have been checked. </li><li>Condition Testing, also known as Predicate coverage testing. It involves evaluating each Boolean expression in the code and checking its output values, TRUE or FALSE, against the expected outcomes. This test checks all outcomes at least once to achieve 100% code coverage. We design test cases that make it easy to execute the condition outcomes. Example: If a program determines whether a user is eligible for a discount based on age, condition testing would verify that the code handles each age group accurately. It would test age values such as one less than, one more than, and within the age range requirement to evaluate if the code performs as expected. </li><li>Multiple Condition Testing aims to test different combinations of conditions to achieve 100% coverage. This technique requires two or more test scripts, which may require more effort. Example: If a program uses an &#8220;if/else&#8221; statement to check age and gender to provide a discount, multiple condition testing would verify that the program handles all possible scenarios correctly. It would test various age ranges and gender combinations to ensure the code performs accurately for all possibilities. </li><li>All Path Testing leverages the source code of a program to find every executable path. Example: If a program asks a user for two inputs (A and B) and has multiple conditions, All Path Testing would ensure that each condition is tested independently. The technique would test all combinations of A and B, including zero, negative, and positive Testings, to identify any potential errors in the code.</li></ol>



By implementing these testing techniques, testers, and developers can ensure the testing code is thoroughly tested and free of unexpected behavior. Choosing the appropriate method based on the project&#8217;s specific requirements is critical.



<h3 id="h-experience-based-techniques">Experience-Based techniques</h3>



The experience-based techniques can be broadly categorized into the following types:



<ul><li>Error Guessing is a testing technique that relies on the testers&#8217; skill, intuition, and experience to anticipate potential errors in the product.</li> <li>On the other hand, Exploratory Testing is a technique used to test applications without any formal documentation. This method is recommended once scripted testing has been executed when working on the software.</li></ul>

Hello there,



Welcome to another interesting blog that discusses the current hardships that we face. The past few years have indeed been tough for all of us. We were all faced with several challenges, both professionally and personally. One of the primary causes for this was COVID-19. Following the epidemic, we are returning to normalcy. Most of us are still dealing with <a href="https://www.who.int/news-room/questions-and-answers/item/coronavirus-disease-(covid-19)-post-covid-19-condition" target="_blank" rel="noreferrer noopener">post-covid symptoms</a> like depression, anxiety, stress, and so on. You may or may not be aware of the implications. However, in order to live a calm existence, it is imperative that these issues be addressed.



In today&#8217;s article, we&#8217;ll look at brain fog and its impacts. Is this a brand-new term? Don&#8217;t be concerned! We&#8217;ve got you covered. Let us study and practice together.



Let&#8217;s study and use some of the finest strategies for overcoming brain fog.&nbsp;



<h2 id="h-defining-brain-fog">Defining Brain fog:</h2>



The word &#8220;brain fog&#8221; refers to feelings of forgetfulness, bewilderment, and mental exhaustion. Brain fog is a prevalent occurrence that affects everyone, particularly in the post-COVID age. While brain fog is not a medical diagnosis, it is a genuine and distressing condition that can have an impact on your quality of life. When you have brain fog, it might be difficult to remember what you&#8217;ve learned, focus on your work, and think clearly. It can also make it difficult to think creatively or make decisions. In rare cases, brain fog might result in memory loss.



Brain fog can cause several symptoms, including:



&#8211; Being forgetful or unable to focus



&#8211; Being confused or disoriented&nbsp;



&#8211; Having difficulty performing activities&nbsp;



&#8211; Being mentally exhausted



 <h2 id="h-identifying-the-causes-of-brain-fog">Identifying the Causes of Brain Fog:</h2>



Brain fog is a prevalent problem that affects people of all ages and socioeconomic backgrounds. A multitude of reasons can contribute to it, including stress, lack of sleep, poor diet, dehydration, and hormone abnormalities.



<ul><li>Stress can overwhelm the brain, rendering it incapable of processing information properly.&nbsp;</li></ul>



<ul><li>Sleep deprivation can make it harder to concentrate and comprehend information.&nbsp;</li></ul>



<ul><li>Poor diet can lead to brain fog because the body needs certain nutrients to function properly.</li></ul>



<ul><li>Dehydration can cause disorientation and difficulties concentrating.&nbsp;</li></ul>



<ul><li>Hormonal imbalances might leave you feeling hazy and distracted.&nbsp;</li></ul>



<ul><li>Additionally, it can be caused by environmental factors like noise or light levels.&nbsp;</li></ul>



Identifying the origin of brain fog is critical for effective treatment. It is critical to monitor lifestyle factors such as stress, sleep, diet, and hydration.



<h2 id="h-what-causes-brain-fog-in-software-testers">What Causes Brain Fog in Software Testers?</h2>



Brain fog can be a debilitating condition for software testers, making it difficult to focus, remember facts, and recall details. It can be a source of frustration and cause of distress for testers, but there are ways to work through it. It is a state of confusion and difficulty to focus, which can make even the easiest of tasks seem difficult. As a software tester, it can be hard to complete tasks when brain fog is on the rise. By identifying the causes of brain fog, software testers can begin to move past it and shine brighter.&nbsp;



There are many possible causes of brain fog for software testers. It can be due to sleeplessness caused by project issues and timelines, improper work-life balance, same mundane project work, missing fun at work, etc. Whatever the cause, brain fog can make it difficult to think clearly and perform at your best.



<h2 id="h-recommended-strategies-to-overcome-brain-fog">Recommended Strategies to Overcome Brain Fog</h2>



We all suffer from brain fog at one time or another. As software testers, we are constantly finding bugs and checking for errors in code, a seemingly endless task. Also, we are gatekeepers of the project, which puts a lot of pressure on us. This can be draining and make it harder to stay focused and efficient. The first step in overcoming brain fog is to identify its source.



If you&#8217;re a software tester and you&#8217;re struggling with brain fog, there are a few things you can do to try and clear it up.



<ul><li>Take regular breaks: It is critical for software testers to take frequent breaks to renew their minds and avoid brain fog. During breaks, they are free to engage in whatever activity they find comforting, such as reading, listening to music, or creating anything really.</li></ul> 



<ul><li>Delegate tasks: Software testers can feel overwhelmed by the amount of work they have to do and feel brain fog due to the amount of pressure they are under. So to avoid this, it is crucial to do a proper work delegation and understand when it&#8217;s necessary to let go of some work and let someone else do it.</li></ul> 



<ul><li>Say &#8220;No&#8221;: As a software tester, it&#8217;s important to be a team player and be able to say &#8216;no.&#8217; You should be able to say &#8216;no&#8217; whenever you are overwhelmed by too much work. Please don&#8217;t wait for the threshold and burst on. Always keep an eye on how you feel and start saying no to any tasks that are not essential and adding to your workload.</li></ul> 



<ul><li>Get adequate sleep: The vast majority of testers work long hours, which might lead to exhaustion. To avoid this, it is crucial to keep a regular sleeping pattern to ensure that your mind and body receive adequate rest. Every day, strive to get 8 hours of good sleep.</li></ul> 



<ul><li>Organize the work and workstation: Staying organized helps you to keep track of tasks and deadlines and make sure that your work is progressing in the right direction. This will help to reduce confusion and make it easier for the tester to focus on the tasks at hand. Organizing doesn&#8217;t mean that you are supposed to complete all the tasks. It’s about prioritizing, deprioritizing, decluttering etc. This will give you clarity on what needs to be done when. Also, please keep your work environment neat and tidy. Organizing your workspace will help you to be more productive, and it will also help you to feel more relaxed and calm.&nbsp;</li></ul> 



<ul><li>Exercise regularly: Exercise not only keeps software testers physically healthy, but it also helps them clear their thoughts and focus more effectively. Regular physical activity also aids in the release of happy hormones, which can assist in boosting mood and maintaining the brain health. Start simple. Begin with walking for 30 minutes a day and gradually increase the amount of time and intensity.</li></ul> 



<ul><li>Eat a balanced diet: One of the biggest causes of fatigue and brain fog is a poor diet. A healthy diet rich in fresh fruits and vegetables is vital for maintaining energy levels throughout the day. <a href="https://carnivorestyle.com/carnivore-diet/meal-plans/" target="_blank" rel="noreferrer noopener">Plan your meal</a> in advance to ensure that you have a healthy, balanced meal. To personalize nutrition for cognitive clarity, consider an <a href="https://www.weightwatchers.com/us/registered-dietitians" target="_blank" rel="noreferrer noopener">online dietitian consultation</a> with registered dietitians who provide virtual counseling tailored to your schedule and workload.</li></ul>



<ul><li>Drink Plenty of Water: Dehydration can cause fatigue and disorientation, so drinking lots of water throughout the day can assist in keeping the mind clear and operating at peak performance.</li></ul> 



<ul><li>Practice positive thinking: Positive thinking is a powerful technique that may help to reduce worries and anxiety. Every day, software testers should practice positive thinking by visualizing their goals, staying present, and thinking about the positives/good results.</li></ul> 



<ul><li>Meditate: Meditation can assist the mind in being in the present moment, boosting attention and decreasing brain fog. The discipline of being attentive and present in the moment, focusing on the current experience, and letting thoughts and emotions pass without getting caught up in them, is known as mindful meditation. By clearing the thoughts of distractions and focusing on what is happening in the now, mindful meditation can help software testers stay focused and enthusiastic.</li></ul> 



<ul><li>Make a routine and stick to it: Developing a routine and sticking to it until it becomes a habit will help ensure that your body and mind get the rest and relaxation they require.</li></ul> 



<ul><li>Change up the Task: Doing the same task for an extended period of time can lead to boredom and exhaustion, therefore, switching tasks can assist in maintaining attention and prevent brain fog.</li></ul> 



<ul><li>Make Time for Fun: Taking time to unwind and enjoy activities outside of work can assist in decreasing stress, improve mental clarity, and rejuvenate the mind.</li></ul> 



<ul><li>Spending time outside in nature: Getting out in nature for a few minutes might assist to clear the mind and make it easier to focus on the subject at hand.</li></ul>



If you&#8217;re still struggling, there are some cognitive-enhancing supplements that you can try. Of course, you need to consult the medical practitioner before that. And finally, if all else fails, you can always take a long break from work and come back to it when you&#8217;re feeling more clear-headed.



<h2 id="h-conclusion-putting-it-all-together">Conclusion: Putting it all Together</h2>



Brain fog can be an obstacle in the software testing profession. However, with the proper knowledge and strategies, it can be managed and even eliminated. We, as software testers, should be more open-minded and enthusiastic so that our brains can help in delivering the best quality products.&nbsp;



Finally, it is important to remember that brain fog affects everyone. It is natural to experience difficulty in focusing at times. By taking regular breaks, staying organized and maintaining a healthy lifestyle, software testers can overcome the effects of brain fog and continue to shine brighter.&nbsp;
