<p>Let&#8217;s talk about something important in the realm of software testing: Robustness testing. ISTQB states, “Robustness testing is the degree to which a component or system can function correctly in the presence of invalid inputs or stressful environmental conditions.&#8221;This is when we test a system or program to see how well it can handle unexpected scenarios and mishaps. </p>



<p>We want to ensure that our software can keep soldiering even if it encounters unexpected situations, like a power outage or memory overload. Nobody wants their system crashing during an important project! </p>



<p>So, in this blog, let&#8217;s look at this testing technique in detail and why it matters so much in ensuring top-notch performance from our software applications.</p>

<h2 id="h-what-is-robustness-testing"><span id="What_is_Robustness_Testing"><strong>What is Robustness Testing?</strong></span></h2>



<p>Robustness testing is software testing that evaluates the capability of a system to operate correctly in unexpected or abnormal conditions. This type of testing is designed to identify possible failures due to unexpected inputs or errors, such as invalid data, network interruptions, or power failures. The goal of robustness testing is to ensure that the system can handle errors and maintain its functions without crashing or becoming unstable, thereby maximizing the software&#8217;s reliability and reducing the risk of failure.</p>



<h3 id="h-why-is-robustness-testing-important"><span id="Why_is_Robustness_Testing_important"><strong>Why is Robustness Testing important?</strong></span></h3>



<p>Here are ten important reasons why robustness testing is important: </p>



<p>1. It uncovers hidden bugs that can cause malfunctions. </p>



<p>2. Improves the reliability and quality of software. </p>



<p>3. Increases customer satisfaction by preventing software crashes. </p>



<p>4. Helps to predict real-world scenarios for better preparedness. </p>



<p>5. Validates the security features of the software. </p>



<p>6. Identifies code weaknesses and restrictions that can be optimized. </p>



<p>7. Enhances the overall software performance across various platforms. </p>



<p>8. Helps to save time and money by avoiding costly bug fixes. </p>



<p>9. Promotes software longevity since it can withstand changes in operating environments. </p>



<p>10. Boosts user confidence in the software by assuring stable and consistent performance.</p>



<h2 id="h-types-of-testing-to-ensure-robustness-of-test-suites"><span id="Types_of_Testing_to_Ensure_Robustness_of_Test_Suites"><strong>Types of Testing to Ensure Robustness of Test Suites</strong></span></h2>



<p>Different types of testing must be done to ensure the robustness of test suites. Here we give you a list:</p>



<ol><li><strong>Functional testing </strong>&#8211; Verifies the software&#8217;s desired behavior under various scenarios. Functional testing conducts numerous tests that examine all software functionalities.</li><li><strong>Regression testing </strong>&#8211; Ensures that software changes do not result in unexpected outcomes in previously tested functionality. Regression testing ensures the software application works correctly even after changes or updates.</li><li><strong>Load testing </strong>&#8211; Examines software performance under various loads and conditions to ensure it can support expected user volume. So this type of testing simulates production loads by subjecting software to a series of tests to ensure it can handle expected traffic.</li><li><strong>Fuzz testing</strong>(Fuzzing Test) &#8211; Sends malicious input to the software to discover vulnerabilities and unexpected behaviors. After conducting fuzz testing, the program is observed for crashes, failed code assertions, and possible memory leaks.</li><li><strong>Mutation testing </strong>&#8211; Changes the software&#8217;s code to see if the test suite can detect these changes and identify issues. Mutation testing aims to detect coding or input flaws that can result in incorrect program output.</li><li><strong>Black-box testing</strong> &#8211; Tests the software&#8217;s external behavior without knowing its internal workings. The tester knows the intended output of the software but lacks knowledge of its internal workings. Functionalities, user interface usability, and conformity with external standards can all be tested using black-box testing.</li><li><strong>Security testing</strong> &#8211; Verifies the software&#8217;s resistance to attacks and potential vulnerabilities. Conducting security testing can help in identifying probable security threats.</li><li><strong>Use case testing</strong> &#8211; Examines the software&#8217;s functionality from the perspective of user scenarios. Conducting Use case testing can help in identifying potential usability issues.</li><li><strong>Negative testing </strong>&#8211; Tests how the software behaves when presented with invalid inputs and unexpected situations. It can reveal input handling or validation mistakes that may result in data loss or leave security gaps.</li><li><strong>Stress testing</strong> &#8211; Evaluate the software&#8217;s increased workload capabilities under heavy load and usage. So, it can detect concerns during intense pressure or heavy workload.</li></ol>



<h2 id="h-robustness-testing-scenarios"><span id="Robustness_Testing_Scenarios"><strong>Robustness Testing Scenarios</strong></span></h2>



<p>Specific scenarios can cause software failure due to a lack of software robustness. The scenarios that can be tested are:</p>



<p>1. Test for handling large amounts of data. </p>



<p>2. Test for unexpected inputs and edge cases. </p>



<p>3. Test for system failures and recovery. </p>



<p>4. Test for long periods of sustained usage. </p>



<p>5. Test for compatibility with various hardware and software environments.</p>

<p>When choosing between these testing, it is essential to consider the specific requirements and objectives of the <a href="https://testsigma.com/guides/test-process/" target="_blank" rel="noreferrer noopener">testing process</a>. Both approaches have advantages and limitations, so a justification for selecting one over the other depends on various factors.</p>



<p>Static testing involves analyzing code without executing it, while dynamic testing involves running code to identify any issues. The choice between static and dynamic testing largely depends on the desired outcome. Static testing may be the way to go if you’re looking to catch coding errors early and improve code quality.&nbsp;</p>



<p>On the other hand, dynamic testing is likely the better choice if you’re concerned with how a program behaves when running.&nbsp; You could also choose to do both according to the results you are expecting.</p>



<p>I conclude by saying both approaches have their strengths and weaknesses. So, it should be completely a decision based on the project’s specific needs.</p>

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



<p>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. </p>



<p>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. </p>



<p>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.</p>



<p>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.</p>

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



<p>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.</p>



<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>



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



<ol><li><strong>Goal of API performance testing</strong>: 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><strong>Environment’s role in testing</strong>: 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><strong>Various Testing methods</strong>: Testers use performance testing tools that simulate user loads, monitor network traffic, analyze response times &amp; other metrics, and identify bottlenecks.</li><li><strong>Metrics</strong>: 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><strong>Importance</strong>: API performance testing helps improve the application&#8217;s overall performance and stability.</li><li><strong>Role of Analysis and reporting</strong>: 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"><span id="Why_Performance_Test_Your_API"><strong>Why Performance Test Your API?</strong></span></h2>



<p>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.</p>



<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"><span id="API_Performance_Testing_Types"><strong>API Performance Testing Types</strong></span></h2>



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



<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"><span id="Ways_of_Measuring_Your_API8217s_Performance"><strong>Ways of Measuring Your API&#8217;s Performance</strong></span></h2>



<p>API performance can be measured by:</p>



<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>



<p><strong>Let&#8217;s have a look at these metrics briefly.</strong></p>



<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>



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



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



<p>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.</p>



<p>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</p>



<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>



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



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



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



<p>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</p>



<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>



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



<p>Here is an example that explains Active API monitoring easily.</p>



<p>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. </p>



<p>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. </p>



<p>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. </p>



<p>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.</p>



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



<p>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,</p>



<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"><span id="Recommendations_for_API_performance_testing"><strong>Recommendations for</strong><strong> API performance testing</strong></span></h2>



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



<ol><li><strong>Decide the testing strategy according to the type of application</strong>: 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><strong>Understand the end-to-end flow of the application</strong>: This is essential to get an accurate picture of overall performance. This will help ensure no bottlenecks or disconnects along the way.</li><li><strong>Remember the underlying technology</strong>: 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><strong>Test in different conditions</strong>: 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>
