Software Application Testing | What it is, Types & How to do?

Response time should be measured in seconds, not minutes.



Every user interaction triggers an action with an expected response time. If the application takes too long to respond, there is definitely an issue that needs fixing. The longer the response time, the higher the abandonment rate. Figures show that more than half the users will leave the site if it takes more than three seconds to load (Source: Envisage Digital). Further, every one-second delay in web page response time results in 16% lower user satisfaction. Clearly, fast response time is critical, which brings us to our topic: response time testing. Let’s see how you can measure and improve the response time of your application through proper testing.

<h2 id="h-what-is-response-time-testing">What is Response Time Testing?</h2>



Response time testing is verifying the time it takes for a software system to respond to a user&#8217;s request or input. It measures the system&#8217;s performance by assessing how quickly it delivers a response under varying loads and conditions. With this type of testing, you can readily identify bottlenecks that contribute to lower user satisfaction and higher load time. For instance, in a web application, response time testing would measure the time it takes for a webpage to load after a user clicks a link. This testing helps ensure that the system is responsive and meets performance expectations.



<h2 id="h-why-is-response-time-important">Why is Response Time Important?</h2>



Multiple reasons play a role in showing how important response time is; for starters, it is a highly critical metric in measuring the performance and usability of a system. And as customers expect faster and more accurate responses, another extremely important parameter to look at is user satisfaction and experience. If more and more users are happy with your system, the response time must be in milliseconds or so. So, a better response time prevents users from losing interest and moving away to a better system. All of this, in turn, contributes to achieving outlined business outcomes and goals, preferably within the time frame and budget.



<h2 id="h-how-to-measure-response-time">How to Measure Response Time?</h2>



The response time of any application depends on its performance. Testers check response time in <a href="https://testsigma.com/blog/performance-testing/" target="_blank" rel="noreferrer noopener">performance testing</a> for the system under realistic and high load conditions to track the time difference between input and output requests. In addition, you can also determine error rate, resource consumption, throughput, and latency parameters to identify which of these add to increased response time.



Automation test tools emerge as a useful part of this process. They track the response time to its accurate value and record the time frame between user request and application response. However, it is possible for different tools to provide varying results, but an average of all these outcomes should help you measure the response time of your system.



<h2 id="h-how-to-interpret-response-time">How to Interpret Response Time?</h2>



Different applications and scenarios impact the response time interpretation. Let’s look at how:



A website with a 1.2-second load time has an excellent response time; however, the same cannot be said for an application that provides real-time financial information. Similarly, the 1.2 seconds response time for a video streaming service is vastly longer. So, you first need to clearly define the expectations to interpret response time as per the type of the system. Once it becomes understandable that various software has differing expected response times, you can easily gear the testing process in the right direction to achieve the utmost business objectives and industry standards.



<h2 id="h-how-to-improve-response-time">How to Improve Response Time?</h2>



By simply identifying the root cause of delay and eliminating them at the earliest! Yet, the thought is far easier than it is in action. The good news is that there are multiple proven and useful methods to improve response time, starting with response time testing. Only when you check and monitor the response time can you see the reasons for a higher response for any user interaction. Some of the strategies that have always been known to prove themselves useful are tracing the factors that contribute to higher response time, debugging the issue accurately, defining the problem, and logging and monitoring the learnings in detail. All these steps help in diagnosing and optimizing the response time to the expected time frame.



<h2 id="h-how-to-benchmark-response-time">How to Benchmark Response Time?</h2>



You know that the time to respond should be low, but by how much? Often, evaluating the current response time against a set benchmark helps. By following a reference point, you can measure and improve the interaction time of your application to improve customer satisfaction and industry competition. We suggest that you accumulate trusted resources to get an idea of the current industry standards for the response time. For starters, you can rely on research papers, recent statistics, customer reviews, case studies, and user feedback. Even some tools help. Two of the most popular are <a href="https://www.webpagetest.org/" target="_blank" rel="noreferrer noopener">WebPageTest</a> and Google’s <a href="https://pagespeed.web.dev/" target="_blank" rel="noreferrer noopener nofollow">PageSpeed Insight</a>.&nbsp;



<h2 id="h-types-of-response-metrics">Types of Response Metrics</h2>



Response metrics in software testing encompass various aspects of a system&#8217;s performance. Some common types of response metrics include:



<ul><li>Average Response Time: The time it takes for the system to provide a response to a user&#8217;s request or action.</li><li>Maximum Response Time: This metric represents the maximum time the system takes to respond to a user request. It helps identify the absolute worst-case scenario for response time.</li><li>Error Rate: The frequency of errors or failed requests during testing, expressed as a percentage of the total requests.</li><li>Peak Performance: Measuring the highest level of performance that the system can achieve under ideal conditions.</li><li>Throughput: The number of transactions or requests the system can process in a unit of time, often measured in requests per second.</li><li>Resource Utilization: Monitoring CPU, memory, disk, and network usage to assess how resources are consumed during testing.</li></ul>



<h2 id="h-three-important-response-time-values">Three Important Response Time Values</h2>



There are three key response time testing values that highlight the performance of a system in general:



<ul><li>0.1 second: An application responding in 0.1 seconds is considered to be ideal with the perfect response time. It shows that there are no performance issues.</li><li>1 second: A response time of 1 second is acceptable if it does not go beyond this time limit. Users may expect some delays but no halt or breakdown in the interaction.</li><li>10 seconds: It goes without saying that the response time of 10 seconds is highly unacceptable. In any case, the time limit should not exceed 10 seconds, considered to be the maximum time to respond, or users will experience interaction issues over a long period.</li></ul>



<h2 id="h-response-time-testing-advantages-and-disadvantages">Response Time Testing Advantages and Disadvantages</h2>

<h2 id="h-what-is-ocr-testing">What is OCR testing?</h2>



Optical Character Recognition (OCR) is the electronic or mechanical conversion of images of typed, handwritten, or printed text into machine-readable text format.



It is used in a wide range of applications, such as:



<ul><li>Converting scanned documents into editable text files</li><li>Extracting text from images for search and indexing</li><li>Transcribing handwritten notes and documents</li><li>Recognizing text on signs and labels</li><li>Automating data entry</li></ul>



Do you want to know how it works?



OCR works by first converting the image into a black-and-white bitmap. The OCR software then analyzes the bitmap to identify characters. This is done by comparing the pixels in the bitmap to a database of character templates. Once the characters have been identified, the OCR software converts them into a machine-encoded text format.&nbsp;



Let&#8217;s see how accurate this technique is.



The accuracy of OCR depends on many factors, including the quality of the image, the size and font of the text, and the complexity of the layout. In general, OCR is very accurate for typed and printed text. However, it can be more challenging to recognize handwritten text, especially if it needs to be better written.



In real life, how OCR can be used:



<ul><li>A business can use OCR to scan and convert paper invoices and receipts into electronic form. This can save time and money on manual data entry.</li><li>A library can use OCR to scan and digitize its collection of books and documents. This makes the collection more accessible to researchers and the public.</li><li>A school can use OCR to scan and grade student exams and essays. This can free up teachers&#8217; time to focus on other tasks.</li><li>A hospital can use OCR to scan and digitize patient records. This can make it easier for doctors and nurses to access patient information.</li></ul>



OCR is a versatile and powerful tool that can be used to improve efficiency and productivity in a wide range of industries.



<h2 id="h-when-to-use-optical-character-recognition-ocr">When to Use Optical Character Recognition(OCR)?</h2>



Text extraction from images is a challenging task, as OCR systems need to accurately recognize a wide variety of fonts, styles, and sizes of text, even in images with poor quality or complex backgrounds.&nbsp;



Use it to



<ul><li>Digitize physical documents: OCR can convert scanned documents, such as invoices, contracts, and receipts, into digital files that can be easily searched, edited, and shared.</li><li>Extract text from images: OCR can be used to <a href="https://www.imagetotext.io/" target="_blank" rel="noreferrer noopener">extract text from images</a>, such as photos of signs, billboards, and product packaging. This can be useful for tasks such as data entry, research, and archiving.</li><li>Make images accessible: OCR can make images accessible to people with visual impairments by converting the text in the image to a machine-readable format.</li></ul>



Here are some specific examples:



<ul><li>To extract text from a scanned PDF file: You have a scanned PDF file of an important document, such as a contract or lease agreement. You need to be able to search and edit the text in the document, but the scanned PDF file is not searchable. You can use OCR to convert the scanned PDF file into a searchable PDF file.</li><li>To extract text from a photo of a sign: You are at a conference, and you see a sign with a list of speakers and their topics. You want to add the information to your calendar, but you want to type only some of it manually. You can use OCR to extract the text from the photo of the sign and then add it to your calendar.</li><li>To make a website accessible: You are developing a website and want to make it accessible to people with visual impairments. You can use OCR to convert the text on your website into a machine-readable format. This will allow screen readers to read the text to people who are blind or have low vision.</li></ul>



OCR technology has improved significantly in recent years, and it is now possible to extract text from images with high accuracy.



<h2 id="h-how-ocr-test-work">How OCR Test work?</h2>



OCR testing uses Optical Character Recognition (OCR) software to extract and convert data from physical documents into a digital format. We have previously read about the working under the how it works section. Here we can look in detail:



The OCR software analyzes the image of the document and identifies individual characters based on their shape and features. The software then outputs the extracted data in many formats, such as text, CSV, XML, and JSON.



OCR testing can be used to test a variety of documents, including invoices, purchase orders, contracts, and legal documents. It can also be used to test scanned images of handwritten documents.



Here are the steps involved in OCR testing:



<ol><li>Scan the document</li></ol>



The first step is to scan the physical document into a digital image. This can be done using a flatbed scanner, a document scanner, or a mobile device with a camera.



<ol start="2"><li>Load the image into the OCR software</li></ol>



Once the document has been scanned, it needs to be loaded into the OCR software. The software will then analyze the image and identify the individual characters.



<ol start="3"><li>Extract the data</li></ol>



The OCR software will then extract the data from the document and convert it into a digital format. The user can specify the format of the output data.



<ol start="4"><li>Verify the data&nbsp;</li></ol>



Once the data has been extracted, it is important to verify it to ensure accuracy. This can be done manually or by using a data validation tool.



OCR testing can be used to automate a variety of data entry tasks.&nbsp;



For example, an OCR testing script could automatically extract data from invoices and import it into an accounting system. We can quote many different examples according to the application.



OCR gives you a quick way.



Then, you have to&nbsp;



do a little bit of editing at the end.



<h2 id="h-how-to-create-ocr-tests">How to Create OCR Tests?</h2>

<h2 id="internet-explorer-history-and-versions">Internet Explorer &#8211; History and Versions</h2>



Are you ready to dig in the sand and discover history?



Internet Explorer: A Brief History



Microsoft developed Internet Explorer (IE) as a web browser. It enjoyed a position of dominance among browsers for a long time but later lost its popularity with the advent of tough competition from Chrome, Firefox, and Safari.



Early Days and Dominance



First versions: The initial Internet Explorer versions were distributed as part of the Windows operating system installation, which ensured that millions of users had it set as their default browser.



Rise to dominance: IE captured a large share of the market during the late 1990s and early 2000s because of its bundling with Windows and contribution toward popularizing the Internet.



Decline and End of Life



Competition: The rise of open-source browsers like Firefox and the revolutionary Chrome further undermined IE&#8217;s market leadership.



Security issues:&nbsp; Trust in IE was flagged as it came under attack for its numerous security loopholes.



End of life: In June 2022, Microsoft officially ended support for Internet Explorer and encouraged all users to switch to the newer Microsoft Edge browser.



Key Internet Explorer Versions



Though there were many versions of Internet Explorer, some of the most notable ones are:



Internet Explorer 3: Added support for tables, frames, and JavaScript.

<h2 id="h-what-is-ui-testing">What is UI Testing?</h2>



UI testing is the process of checking the user interface of the software. The purpose of UI testing is to make sure that all the visible and interactive elements on the screen, such as menus, buttons, icons, and more, work appropriately. For instance, a clickable button on the Testsigma homepage, like ‘Try Testsigma Cloud’ is a UI element that requires testing to function properly.



Some of the other UI objects are images, gifs, texts, font sizes, dropdowns, checkboxes, font color, and tables on a webpage.

9 Useful UI Test Cases for Testing User Interfaces

Imagine you&#8217;re overseeing the construction of a crucial bridge that will connect two bustling cities. This bridge is not just a physical structure; it symbolizes the flow of commerce, ideas, and connections between communities. Now, picture the potential consequences if this bridge has a structural flaw that goes undetected. The scenario becomes a recipe for disaster.&nbsp;



In the realm of software development, the analogy holds true – applications are the bridges that connect users to services, and vulnerabilities in these applications can lead to catastrophic consequences. This is where fuzz testing steps in. In this article, we will explore the world of fuzz testing, understanding its history, mechanics, benefits, and challenges, while also discussing best practices and solutions to address its limitations.

<h2 id="what-is-the-history-of-fuzz-testing">What is the History of Fuzz Testing?</h2>



The roots of fuzz testing can be traced back to the 1980s when it emerged as a method for testing parsers in Unix utilities. These parsers were responsible for processing and interpreting data, making them a critical component of software systems. The concept of feeding unexpected and malformed data to these parsers to identify vulnerabilities quickly gained traction. As the software landscape expanded, so did the complexity and interdependencies among software components. Consequently, the need to discover vulnerabilities became even more critical.



The 1990s marked a turning point in the history of fuzz testing, as it gained prominence in the security community. As applications grew more complex and connected, security researchers and hackers alike recognized the potential of fuzzing to uncover vulnerabilities. Fuzz testing began to reveal a wide range of issues, from memory leaks and crashes to more severe security vulnerabilities. In response to this, security professionals and developers started incorporating fuzz testing into their testing processes.



<h2 id="what-is-fuzz-testing">What Is Fuzz Testing?</h2>



Fuzz testing, often referred to simply as &#8220;fuzzing,&#8221; is a dynamic software testing technique designed to unearth vulnerabilities and defects by bombarding a software application with unexpected and invalid inputs. These inputs, known as &#8220;fuzz,&#8221; can encompass a spectrum of data types, including random strings, special characters, and even carefully crafted malicious inputs. The primary goal of fuzzing is to push software systems to their limits and observe how they respond under unexpected conditions.



Think of a web application that accepts user inputs for search queries. Traditional testing might involve inputting valid search terms and ensuring that the application produces accurate results. However, fuzz testing takes a different approach. It introduces inputs that deviate from the norm – strings with excessive lengths, characters with unusual encoding, or symbols that the application may not handle gracefully. The intention is not only to identify vulnerabilities but also to explore the application&#8217;s boundaries and uncover unexpected behavior.



<h2 id="types-of-fuzz-testing">Types of Fuzz Testing</h2>



Fuzz testing comes in various flavors, each tailored to address specific aspects of software systems:



<ol><li>File Fuzzing: This technique involves supplying malformed files to an application to gauge its resilience. For instance, sending corrupted image files or documents to an image processing application can reveal how well it handles unexpected data.</li><li>Protocol Fuzzing: Network protocols serve as the backbone of communication between systems. Protocol fuzzing targets these protocols by sending malformed data packets, helping to detect vulnerabilities in network communication and security.</li><li>API Fuzzing: Application Programming Interfaces (APIs) enable communication between different software components. API fuzzing involves sending unexpected inputs to API endpoints to uncover security flaws, crashes, or unexpected behavior.</li><li>Mutation Fuzzing: In mutation fuzzing, existing inputs are slightly altered to create new inputs. This technique aids in exploring different code paths and identifying vulnerabilities that might be triggered by small variations in input.</li><li>Generation Fuzzing: Generation fuzzing takes a more structured approach. It utilizes predefined grammar rules to generate valid but unexpected inputs for testing, increasing the likelihood of uncovering vulnerabilities.</li></ol>



<h2 id="how-does-fuzz-testing-work">How Does Fuzz Testing Work?</h2>



Fuzz testing follows a systematic approach that comprises several steps:



<ol><li>Input Generation: Fuzzers generate a large volume of test inputs by modifying data, files, or network packets in unpredictable ways. This results in a diverse array of inputs that simulate various real-world scenarios.</li><li>Input Injection: The generated inputs are injected into the target application, simulating how the application responds to unexpected data. The application&#8217;s behavior is closely monitored during this phase.</li><li>Analysis: If the application reacts unexpectedly or crashes, the fuzzer captures the input that triggered the issue. This input is then examined by developers to identify the underlying cause of the problem.</li><li>Bug Reporting: Fuzzers usually generate detailed <a href="https://testsigma.com/blog/how-to-write-a-good-bug-report-some-tips/" target="_blank" rel="noreferrer noopener">bug reports</a> that include information about the input that led to the issue. These reports aid developers in replicating and addressing the problem effectively.</li></ol>



This process helps uncover vulnerabilities that might have remained hidden during traditional testing. By focusing on unconventional inputs, fuzzing can simulate attack scenarios that real-world adversaries might employ.



<h2 id="fuzz-testing-applications">Fuzz Testing Applications</h2>



The applications of fuzz testing span diverse domains, showcasing its versatility and significance:



<ul><li>Web Applications: Fuzz testing is an invaluable tool for uncovering vulnerabilities in web applications. It can identify issues such as inadequate input validation, cross-site scripting (XSS) vulnerabilities, and SQL injection vulnerabilities.</li><li>Network Protocols: Fuzzing network protocols helps to detect vulnerabilities in the communication channels between systems. This is essential for maintaining the security and integrity of data transfers.</li><li>Operating Systems: Fuzz testing aids in identifying vulnerabilities in operating systems. It can uncover flaws that could lead to privilege escalation, system crashes, or unauthorized access.</li><li>Embedded Systems: With the proliferation of Internet of Things (IoT) devices and embedded systems, the need for rigorous testing has grown. Fuzz testing ensures the reliability and security of these systems in various applications, including medical devices, automotive systems, and smart appliances.</li></ul>

<h2 id="h-the-imperative-of-software-quality">The Imperative of Software Quality</h2>



In today&#8217;s digital age, software has permeated nearly every aspect of our lives. From the apps on our smartphones to the systems that power critical infrastructure, the quality and reliability of software have a direct impact on our daily experiences. In this context, statistics paint a compelling picture of the importance of robust <a href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a> methodologies.



According to a recent study by Capers Jones, a renowned expert in software engineering metrics, software defects cost the global economy an estimated $312 billion annually. Moreover, the same study found that the cost of fixing defects increases exponentially as they move through the development process. For instance, a defect identified during the design phase may cost a few hundred dollars to fix, while the same defect, if discovered during maintenance, can cost thousands or even millions to rectify.



These statistics highlight the critical role of testing in the software development lifecycle and the need for effective methodologies like the Spiral Model.



<h3 id="h-what-is-the-spiral-model">What is the Spiral Model?</h3>



The Spiral Model is like a versatile tool for building software, and it was created by a software expert named Barry Boehm in 1986. It was designed to overcome the limitations of the traditional <a href="https://testsigma.com/blog/waterfall-model-in-software-testing/" target="_blank" rel="noreferrer noopener">Waterfall Model</a>.



Imagine building software as a journey. Instead of taking one big step, the Spiral Model breaks the journey into smaller, manageable steps called &#8220;spirals.&#8221; Each spiral is like a mini-journey that includes planning, checking for potential problems, building, testing, and evaluating. We repeat these spirals until our software is ready to be used by people.&nbsp;



It&#8217;s a bit like taking one step at a time, making sure everything works well before moving forward, and doing this in a cycle until we reach our destination, which is a fully functioning software product.
