<h2 id="h-what-is-a-performance-profile">What is a Performance Profile?</h2>



A performance profile is an analysis of a software&#8217;s behavior while executing. It comprises data derived from various aspects such as run time behavior and resource utilization.



&nbsp;Performance profiling is a method of producing these profiles by analyzing a software with respect to certain metrics such as the time taken to execute a function, CPU time utilization, memory usage, run time behavior and resource utilization. It aids in identifying bottlenecks in your code and hence helps to improve your code.&nbsp;



<h2 id="benefits-of-performance-profiling">Benefits of Performance Profiling</h2>



There are several benefits of adapting performance profiling. Some of them are discussed in this section.



<ol><li>Improved code quality &#8211; Performance profiling helps in identifying sections of code that hamper the overall software execution. This helps in rectifying the code and hence improves code quality.</li></ol>



<ol start="2"><li>Efficient software &#8211; Performance profiling analyses a software against various aspects. Thus, it helps in developing an optimized and efficient software.</li></ol>



<ol start="3"><li>Resource Allocation &#8211; Performance profiling analyses and provides results based on resource utilization. This helps to efficiently plan, allocate resources, and ensure they are being used correctly.</li></ol>



<ol start="4"><li>Improved User Experience &#8211; With performance profiling, you get a better working application. This, in turn, improves user experience.</li></ol>



<ol start="5"><li>Scalability &#8211; A software can be continuously improved with performance profiling. This enables the software to take increased load and traffic without any significant performance degradation.</li></ol>



<h2 id="what-are-the-stages-of-performance-profiling">What are the stages of Performance Profiling?</h2>



<ol><li>Define Objectives &#8211; The team should decide what needs to be analyzed before starting the process. Define the parameters (like CPU utilization, memory consumption, resource utilization, and so on) based on which the performance profiling should be done.&nbsp;</li></ol>



<ol start="2"><li>Select the <a href="https://www.sciencedirect.com/topics/computer-science/profiling-tool" target="_blank" rel="noreferrer noopener">Profiling tools</a> &#8211; Choose a tool based on the programming language, platform, and the type of data to be collected.&nbsp;</li></ol>



<ol start="3"><li>Instrument your code &#8211; Mark and set up your code to collect the required data. This depends on the tool that is being used for performance profiling.</li></ol>



<ol start="4"><li>Write test cases &#8211; Prepare a number of test cases to satisfy all the required conditions and workload.</li></ol>



<ol start="5"><li>Profiling Setup and Code Execution &#8211; Configure the profiling tools and ensure that the environment is set up to collect the data.&nbsp; Once the configuration is completed, execute your code to collect the data. Also, work on different use cases to get all possible data.</li></ol>



<ol start="6"><li>Data Analysis &#8211; The data collected from different cases are analyzed by the team. If there are any code bottlenecks detected, they are to be rectified.</li></ol>



<ol start="7"><li>Code optimization &#8211; After analyzing all the data, any deviations detected are repaired to ensure an optimized, better performing, and less resource-using code.&nbsp;</li></ol>



Performance profiling is an iterative process. The above stages are repeated until the performance is at an acceptable level.



<h2 id="performance-testing-vs-performance-profiling">Performance Testing Vs Performance Profiling</h2>



Now that you have understood what performance profiling is, you might have a doubt if Performance profiling is the same as Performance testing. Let us address the topic in this section. Performance testing and Performance profiling are related topics but are used at different stages of software development.

<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.

<h2 id="h-what-are-ui-test-cases">What are UI Test Cases?</h2>



UI test cases are the list of tests that focus on verifying the functionality and behavior of a software application&#8217;s user interface. These test cases ensure that the application&#8217;s graphical elements, such as buttons, menus, forms, and visual components, work as expected and provide a positive user experience. GUI test cases include functional UI testing, layout and design testing, <a href="https://testsigma.com/blog/navigation-testing/" target="_blank" rel="noreferrer noopener">navigation testing</a>, input validation and error-handling testing, and <a href="https://testsigma.com/guides/usability-testing/" target="_blank" rel="noreferrer noopener">usability testing</a>.<gwmw style="display:none;">



<h2 id="h-how-to-write-ui-test-cases">How to Write UI Test Cases?</h2>



To understand how to create UI test cases, let’s take an example of the <a href="https://testsigma.com/" target="_blank" rel="noreferrer noopener">Testsigma</a> homepage. The webpage has multiple interactive and visible UI elements that we can reference for this task. You can refer to the below UI test case examples for general use.



<ul><li>Test if the user can navigate to the homepage.</li><li>Check if the page is displaying correctly without any broken elements, such as images or text.</li><li>Verify that the user can click on various buttons present on the page, like Schedule a demo, Try Testsigma Cloud, Learn more, and Start a Free Trial.</li><li>Test if the menu dropdown is accessible to the user.</li><li>Test if the user can click on several options available under the menu tab.</li><li>Verify that the links added in the page footer are clickable by the user.</li><li>Verify that the page title is displayed at the top.</li><li>Test that any new links or images added to the page do not break the existing UI.</li></ul>



<h2 id="h-how-to-run-ui-test-cases">How to Run UI Test Cases?</h2>



Once you have a list of UI test cases, running them comes as the next step. Testers either choose manual or <a href="https://testsigma.com/guides/automated-ui-testing/" target="_blank" rel="noreferrer noopener">automated UI testing</a> options to execute tests. Keeping both these approaches in mind, we give you sequential steps to running GUI test cases:



<ul><li>Understand Requirements: Familiarize yourself with design and functional requirements.</li><li>Identify <a href="https://testsigma.com/guides/test-scenario/" target="_blank" rel="noreferrer noopener">Test Scenarios</a>: List scenarios, user interactions, and workflows.</li><li>Prioritize Test Cases: Rank cases based on criticality and usage.</li><li>Create Test Cases: Craft clear test cases with titles, steps, data, and expected outcomes.</li><li>Include Data: Specify input values, credentials, and expected data.</li><li>Handle Variations: Cover diverse data and edge cases.</li><li>Document UI Elements: Clearly identify elements to interact with.</li><li>Test Data and Environment: Specify test data and the testing environment.</li><li>Sequence and Flow: Ensure logical sequence for user workflows.</li><li>Assertions: Define verifications to match expected and actual UI elements.</li><li>Negative Scenarios: Include error-triggering tests for validation.</li><li>Screenshots: Attach images to clarify the expected UI appearance.</li><li>Review and Validation: Ensure accuracy, clarity, and completeness.</li><li>Data Preparation: Provision required test data and configurations.</li><li>Automation Consideration: Identify opportunities for UI test automation.</li><li>Documentation: Maintain organized test case documentation.</li><li>Execution Plan: Plan test execution in the designated environment.</li><li>Execution and Reporting: Execute, record results, and report defects.</li></ul>



<h2 id="h-manual-and-automated-ui-test-case-examples">Manual and Automated UI Test Case Examples</h2>



As we move toward putting the list of tests into the execution phase, understanding manual and automated approaches is important. This way, testers can easily differentiate on which tests to run manually or automatically.



Let’s take a look at manual test cases for a login scenario.



<ul><li>Verify that the user can access and enter details into login fields: username and password.</li><li>Test login with an incorrect username and ensure the appropriate error message is displayed.</li><li>Test logging in with both the username and password fields left empty and confirm that a relevant error message is displayed.</li><li>Verify that the login page displays a warning if the Caps Lock key is on during password entry.</li><li>Check if the ‘Remember Me’ button is clearly visible to the user.</li><li>Check if the ‘Remember Me’ button is interactive and clickable.</li><li>Test the integration with social login providers (e.g., Google, Facebook) and ensure users can log in using those options.</li><li>Simulate a session timeout and verify that the user is redirected to the login page with an appropriate message.</li><li>Check the login page&#8217;s responsiveness on various devices (e.g., smartphones and tablets) to ensure it functions and displays correctly.</li><li>Test for various error conditions, such as server unavailability, and ensure user-friendly error messages are displayed.</li><li>Ensure that the login page aligns with the branding and design guidelines, including logo placement and color schemes.</li></ul>

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.

It defines what needs to be tested and the expected outcomes.</td><td>A test item refers to the entire software application or a specific component or module that is being tested as a whole. It represents the software or part of it that is the subject of the testing effort.</td></tr><tr><td>Test conditions help in specifying what aspects of the software will be tested and what criteria should be met for the test to be considered successful.</td><td>Test items are the entities that you are testing. They can be a complete software system, a software module, or even individual features or functionalities.</td></tr><tr><td>Example: In testing a banking application, a test condition could be to verify the functionality of transferring funds between two accounts to ensure that the correct amount is deducted from one account and added to the other, and that the user receives a confirmation message.</td><td>Example: If you&#8217;re testing a complete e-commerce website, the entire website, including the user interface, shopping cart, payment gateway, and database integration, is the test item. However, you can also have test items at a smaller scale, such as testing just the login module within that website.</td></tr></tbody></table></figure>



<h3 id="h-what-s-the-difference-between-test-condition-vs-test-scenario">What&#8217;s the Difference between Test Condition vs. test Scenario ?</h3>



<figure class="wp-block-table"><table><tbody><tr><td>Test Condition</td><td>Test Scenario</td></tr><tr><td>A test condition is a specific, detailed element or aspect of the software that is being evaluated in testing. It specifies what needs to be tested, including inputs, expected results, and conditions.</td><td>A test scenario is a broader, high-level description of a testing situation that encompasses multiple test conditions and simulates a real-world use case or user interaction.</td></tr><tr><td>Test conditions are more granular and specific, focusing on individual features, functions, or aspects of the software.</td><td>Test scenarios are less granular and describe a sequence of activities or a complete end-to-end process, often combining multiple test conditions.</td></tr><tr><td>The purpose of test conditions is to examine and validate the detailed functionality or attributes of the software, typically in isolation.</td><td>Test scenarios are designed to assess the software&#8217;s behavior in real-world contexts, considering how various features and components work together to achieve a specific user goal</td></tr><tr><td>Example: In a travel booking website, a test condition could focus on validating the functionality of the &#8220;search&#8221; button, ensuring that it returns accurate results when a user enters specific travel dates and destinations.</td><td>Example: A test scenario for the same travel booking website might involve a complete booking process, including multiple test conditions like searching for flights, selecting a flight, entering passenger information, making a payment, and receiving a booking confirmation.</td></tr></tbody></table></figure>
