Salesforce QA Testing – What, Why, and How to Perform?

Defect density is crucial when testing software and ensuring its high quality, because it measures the number of defects in the software compared to how big the software is in terms of lines of code or function points.&nbsp;



When doing test automation, defect density becomes even more important because it helps you determine which software parts are more likely to have issues and need more testing.&nbsp;



Monitoring defect density over time also tells you if your improvements are making a difference, so it&#8217;s a great tool for keeping your software improving.



Lets discuss more in detail about Defect Density in this blog.

<h2 id="h-what-is-defect-density">What is Defect Density?</h2>



Defect Density is a measure used in <a href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a> to quantify the number of defects found in a piece of software or a component relative to its size. It is typically expressed as the number of defects per thousand lines of code (KLOC).&nbsp;



This metric helps assess the software&#8217;s quality and reliability, guiding project teams in identifying areas that need more focused testing and improvement.



<h2 id="h-how-to-calculate-defect-density">How to calculate Defect Density?</h2>



We can calculate it using the following formula:



Defect Density = (Number of Defects) / (Size of the Software Entity)



The size is typically measured in<a href="https://en.wikipedia.org/wiki/Source_lines_of_code" target="_blank" rel="noreferrer noopener nofollow"> Lines of Code</a> (LOC), Function Points (FP), or modules/components. The chosen unit depends on the project context and industry standards.



For example, if a software application has 50 confirmed defects and the size is 10,000 lines of code, then the Defect Density would be 0.005 defects per line of code.



<h2 id="h-defect-density-example">Defect Density Example</h2>



Let us look at two different examples to understand better about this:



<ol><li>Defect Density Example: E-commerce Website</li></ol>



Imagine we&#8217;re developing a new e-commerce website. Here&#8217;s how defect density can be applied:



Scenario:



<ul><li>The website has 200 confirmed defects after testing.</li><li>The size is measured in Function Points (FP), estimated to be 100 FP.</li></ul>



Calculation:



Defect Density = (Number of Defects) / (Size of the Software Entity)



Defect Density = 200 defects / 100 FP



Defect Density = 2 defects per FP

Interpretation:



This is a relatively high defect density. While a specific benchmark depends on the e-commerce industry and development approach (Agile might have a slightly higher tolerance), it suggests room for improvement.



Further Analysis:



<ul><li>We should analyze the severity distribution of defects. Are there any critical bugs or mostly minor UI issues?</li><li>We can track defect density over different development phases. Did it decrease after additional testing cycles?</li></ul>



Decision Making:



Based on the analysis, we can decide on:



<ul><li>Additional testing: More testing might be needed if critical defects are prevalent.</li><li>Process improvement: Are there recurring defect types? This might indicate a need for improved coding practices or code reviews.</li><li>Release prioritization: If resources are limited, fixing high-impact defects might take priority before addressing minor ones.</li></ul>



This example highlights how defect density provides a starting point for software quality assessment, leading to further analysis and informed decisions regarding testing and development processes.



<ol start="2"><li>Defect Density Example: Mobile App with Severity Levels</li></ol>



Let&#8217;s consider a mobile app with two functionalities: login and news feed. We&#8217;ll track the defects found during testing and categorize them by severity (critical, major, minor).



Scenario:



<ul><li>Login functionality: 10,000 lines of code (LOC) <ul><li>Critical defects: 2 (e.g., app crashes on login)</li><li>Major defects: 3 (e.g., login fails with incorrect error message)</li><li>Minor defects: 5 (e.g., missing visual element on login screen) </li></ul></li><li>News feed functionality: 15,000 LOC <ul><li>Critical defects: 1 (e.g., news feed crashes after loading)</li><li>Major defects: 4 (e.g., news feed displays outdated information)</li><li>Minor defects: 7 (e.g., typos in news articles)</li></ul></li></ul>



Defect Density Calculation (focusing on critical and major defects):



<ol><li>Overall: <ul><li>Total critical defects: 2 (login) + 1 (news feed) = 3</li><li>Total major defects: 3 (login) + 4 (news feed) = 7</li><li>Total critical &amp; major defects: 3 + 7 = 10</li><li>Total LOC: 10,000 (login) + 15,000 (news feed) = 25,000</li><li>Defect Density = 10 defects / 25,000 LOC = 0.0004 defects/LOC </li></ul></li><li>Per Functionality: <ul><li>Login: (2 critical + 3 major) / 10,000 LOC = 0.0005 defects/LOC</li><li>News feed: (1 critical + 4 major) / 15,000 LOC = 0.00033 defects/LOC</li></ul></li></ol>



Analysis:



<ul><li>The overall defect density (0.0004 defects/LOC) is relatively low, indicating good software quality.</li><li>However, the login functionality has a slightly higher defect density than the news feed.</li><li>This might suggest focusing additional testing efforts on the login functionality, especially considering the critical defects found there.</li></ul>



<h2 id="h-uses-of-defect-density">Uses of Defect Density</h2>



Here are the major uses:



<ol><li>Assessing Software Quality: Look at defect density to gauge the number of defects relative to the software size. Lower defect density usually signals better quality. </li><li>Prioritizing Testing Efforts: First, focus your testing on areas with higher defect densities. This ensures the critical parts are solid before anything goes live. </li><li>Monitoring Progress: Keep an eye on defect density over time. It&#8217;s a good indicator of whether your testing strategies are effective and how software quality is evolving. </li><li>Making Release Decisions: Use defect density as one of the factors to decide if a product is ready for release. Remember, the severity of any remaining defects matters too. </li><li>Comparing Teams or Projects: Defect density can help compare software quality across different teams or projects. Remember to factor in the project complexity and industry benchmarks for a fair comparison.</li></ol>



<h2 id="h-factors-affecting-defect-density-metrics">Factors Affecting Defect Density Metrics</h2>



Here are some of the factors:



<ol><li>Project Complexity: More complex projects tend to have higher defect densities due to the intricate interactions between different software parts. </li><li>Team Experience and Skill Level: Experienced and skilled teams are generally more adept at producing higher-quality code, resulting in lower defect densities. </li><li>Development Methodology: Agile, DevOps, and similar methodologies incorporating continuous testing and feedback can lead to lower defect densities than traditional waterfall approaches. </li><li>Software Size: Larger software projects might show a different defect density simply because of their size. The metric needs to be interpreted carefully to account for this. </li><li>Testing Coverage and Quality: The extent and thoroughness of testing can significantly impact defect density. More comprehensive testing usually uncovers more defects, potentially raising defect density in the short term but improving overall quality. </li><li>Tool Usage: <a href="https://testsigma.com/qa-automation-tools" target="_blank" rel="noreferrer noopener">Automated testing tools</a>, static code analysis tools, and other quality assurance technologies can influence defect detection rates and, consequently, defect density. </li><li>Project Phase: Software in earlier development stages may exhibit higher defect densities, typically decreasing as the project matures and more defects are resolved. </li><li>Code Reuse: Projects that leverage a significant amount of well-tested, previously used code may exhibit lower defect densities due to the maturity of the reused components. </li><li>Documentation and Specification Clarity: Clear, detailed requirements and documentation can reduce misunderstandings and errors in implementation, which can affect defect density. </li><li>External Factors: Changes in project scope, tight deadlines, and other external pressures can lead to shortcuts in development and testing, potentially increasing defect density.</li></ol>



Understanding these factors can help interpret defect density metrics more accurately and make informed decisions.



<h2 id="h-advantages-of-defect-density">Advantages of Defect Density</h2>



Defect density, while not without limitations, offers several advantages:



<ul><li>Quantifies Software Quality: It calculates defects relative to software size, allowing for objective comparisons and tracking progress over time.</li><li>Prioritizes Testing Efforts: By identifying areas with higher defect density, teams can focus testing resources on those modules or functionalities most susceptible to issues.</li><li>Improves Development and Testing Processes: Monitoring defect density trends helps assess the effectiveness of current practices. A sustained decrease suggests improvements in development and testing approaches.</li><li>Informs Release Decisions: Defect density can be considered when deciding if the software is ready for release. Lower defect density generally indicates a higher likelihood of a stable and reliable product.</li><li>Benchmarks Progress: By comparing defect density against industry standards or historical data for similar projects, teams can gauge their relative performance and identify areas for potential improvement.</li></ul>

<h2 id="h-calculate-defect-density-for-test-automation">Calculate Defect Density For Test Automation</h2>



In test automation, you do calculate defect density, but with a slightly different approach than manual testing, mainly because automation has its own unique features.



Here&#8217;s a step-by-step guide on how to calculate defect density for test automation:



<ol><li>Identify the Scope: Determine the scope of your test automation efforts. This could be a specific module, feature, or the entire application.</li><li>Execute Automated Tests: Run your automated test suites against the identified scope. These tests should cover a variety of scenarios to ensure comprehensive coverage.</li><li>Record Defects: As your automated tests run, record any defects or issues identified by the tests. These could be failures, unexpected behavior, or anything that deviates from the expected outcome.</li><li>Count Lines of Code (LOC): Determine the lines of code covered by your automated tests within the scope. This is essential for calculating defect density. You can use tools or scripts to count the lines of code in the tested modules or features.</li><li>Calculate Defect Density: As we discussed before, once you have the total number of defects found and the lines of code covered by your automated tests, you can calculate defect density using the formula:</li></ol>



&nbsp;Defect Density = (Number of Defects Found / Lines of Code Covered) * 1000 



This formula normalizes the defect count per thousand lines of code, providing a standardized measure that can be compared across different modules or projects.



<ol start="6"><li>Analyze and Interpret: After calculating defect density, analyze the results. A higher defect density indicates a higher likelihood of defects within the tested codebase, suggesting lower quality. Conversely, a lower defect density suggests better code quality and fewer defects.</li><li>Iterate and Improve: Use the insights gained from defect density calculations to refine your automated testing strategy. Identify areas where defects are frequently found and prioritize improvements to your tests or the underlying code.</li></ol>



It&#8217;s important to note that while defect density is needed to provide a complete picture of software quality, it should be used with other metrics and qualitative assessments to make informed decisions about the effectiveness of your test automation efforts and the overall quality of your software.

<h2 id="h-summary">Summary<gwmw style="display:none;"></h2>



To summarize, defect density is the ratio of defects found to software size (lines of code, modules). It helps assess software quality—lower density indicates better quality. While useful, it doesn&#8217;t tell the whole story; consider defect severity and use it alongside other quality metrics.



<h2 id="h-frequently-asked-questions">Frequently Asked Questions</h2>



<h2 id="h-what-is-a-good-defect-density">What is a good defect density?</h2>



First, there&#8217;s no single &#8220;good&#8221; defect density, as it depends on factors like project complexity and development methodology.&nbsp;



Generally, a lower defect density (e.g., less than 1 defect per thousand lines of code) suggests higher quality, but always consider the severity of remaining defects.



<h2 id="h-what-is-a-normal-defect-rate">What is a normal defect rate?</h2>



A normal defect rate varies based on industry and project complexity but typically ranges from 1 to 5 defects per thousand lines of code in software development.

Defect Density: How To Calculate For Test Automation?

Making sure that all the front-end functionalities of your software application work perfectly is not the only aspect that we should take care of as testers. Because the back end of your software product is the base of everything, this is why webhook testing is very important.&nbsp;



Webhook Testing is an important aspect of <a href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a> and it helps to ensure effective communication with other applications.

<h2 id="h-what-is-webhook-testing">What is Webhook Testing?</h2>



Webhook Testing is the process of verifying the functionality and reliability of <a href="https://en.wikipedia.org/wiki/Webhook" target="_blank" rel="noreferrer noopener">webhooks</a>. In case you are wondering what a webhook is, a webhook is a personalized notification that gets activated or triggered by specific events such as user registrations, changes to database records, security alerts, new messages, IoT device triggers, etc. When those events occur, a message is sent to a web server (which is not the one that is hosted for the original web page) using an HTTP POST request. This message may contain the latest real-time data or updates related to the triggered event.<gwmw style="display:none;">



Under webhook testing, testers ensure that the webhook is configured correctly, whether it sends and receives data as expected, and whether it handles various scenarios smoothly such as errors and timeouts. Webhook testing is important for developers to make sure that the respective integrations are correctly done and that the data flow goes between systems with no issues.



<h2 id="h-types-of-webhook-testing">Types of Webhook Testing</h2>



Webhook testing can be divided into four different types. Let’s get to know what they are and why they are so important when ensuring system integration.



<h3 id="h-unit-testing-webhooks-for-logic-errors">Unit Testing Webhooks for Logic Errors</h3>



In this type of webhook testing, testers mainly focus on verifying the individual components or units of the webhook’s logic. Developers check whether each part of the webhook’s code behaves as expected while catching errors or bugs that may occur within the logic of the webhook. This makes sure that the basic components of the webhook work correctly and identifies the potential issues that can occur at the earliest in the software development lifecycle.



<h3 id="h-functional-testing-of-webhook-workflows">Functional Testing of Webhook Workflows</h3>



In this type of webhook testing, testers verify the entire workflow&#8217;s end-to-end functionality. Usually, testers trigger the webhook by executing the respective events, and then they verify whether all the individual tasks starting from the trigger initiation to the response generation, work as expected with no issues. This type of testing ensures that the webhook not only performs individual tasks correctly but also that it integrates smoothly.



<h3 id="h-load-testing-webhooks-for-resilience">Load Testing Webhooks for Resilience</h3>



This sort of webhook testing deals with how a webhook works under high user traffic. There, the testers create a lot of events to evaluate the webhook&#8217;s ability to handle such massive loads while checking that the webhook remains responsive and doesn&#8217;t produce errors or any other types of issues even during the high-usage periods. This type of testing is very important when it comes to finding the performance bottlenecks in the software systems, scalability concerns, and resource limitations such as memory and disc limitations specifically in the performance of specific webhooks.



<h3 id="h-profiling-webhooks-for-performance-improvements">Profiling Webhooks for Performance Improvements</h3>



Under profiling webhooks for performance improvements, testers evaluate the webhooks&#8217; performance and identify all the areas in which the performance should be improved. In addition to that, the testers check different elements of the webhook such as its response time, resource utilization, etc. Developers can identify performance bottlenecks and optimize the code to improve overall efficiency while designing a more reliable webhook by profiling code.



<h2 id="h-how-to-test-webhooks">How to Test Webhooks?</h2>



For some QA engineers, webhook testing can be quite new thus, they might not know how to test webhooks exactly.&nbsp;



<h3 id="h-testing-webhook-via-automated-testing-tools">Testing Webhook via Automated testing tools</h3>



<a href="https://testsigma.com/qa-automation-tools">Automated testing tools</a> evaluate webhooks by simulating triggering events, verifying valid payload structure, and validating HTTP responses and status codes. These tools test proper header handling, and endpoint accessibility, and test retry mechanisms of webhooks. Security checks, including SSL/TLS validation, are performed, while testing also covers timeout handling, redundancy, and failover mechanisms. Apart from that &#8211;&nbsp; logging, error handling, and concurrency testing help to a comprehensive assessment of the application.



<h3 id="h-testing-webhook-code-locally">Testing Webhook Code Locally</h3>



When testing webhook code locally, developers create a separate test environment on their local machines, and with that, they can simulate webhook events and observe how the code responds. First of all, developers set up a testing server to expose their created local server to the internet temporarily. Then they trigger events and monitor the behavior of the webhook code while debugging the issues if there are any. Testing webhook code locally is very important when it comes to executing efficient and fast iterations during the development phase while ensuring that the webhook works correctly before deploying it to the production environments.



<h3 id="h-testing-webhook-delivery">Testing Webhook Delivery</h3>



When testing webhook delivery, testers validate the end-to-end process of delivering webhook payloads. There, they confirm that the webhook is correctly configured to receive and process data. Also, they ensure that the sender can deliver payloads to the configured endpoint with no issues. While testing webhook delivery, testers inspect webhook payloads, verify the HTTP status codes, and analyze response messages using tools. This type of testing helps identify and address any issues related to the webhook&#8217;s communication and data transfer tasks while ensuring reliable and timely delivery of information between systems.

<h2 id="h-frequently-asked-questions">Frequently Asked Questions</h2>



<h3 id="h-can-i-test-webhooks-in-postman">Can I test webhooks in Postman?</h3>



Testing webhooks using Postman is possible. Even though Postman is traditionally used for testing APIs, it provides features for webhook testing as well. Through Postman, you can create and send HTTP requests to simulate webhook events. Also, it helps to inspect the responses and validate the behavior of your webhook. Postman offers a comprehensive environment for developers to evaluate and debug their integrations.



<h3 id="h-what-is-the-difference-between-api-and-webhook">What is the difference between API and webhook?</h3>



The primary difference between an API and a webhook is the way they communicate between software systems. An API is a set of protocols and tools that allows different software applications to communicate with each other. However, a webhook is a user-defined HTTP POST call that should be triggered by specific events. While APIs enable communication instances between systems, webhooks are more about notifications triggered by specific events.<gwmw style="display:none;">

Over time, the client&#8217;s Salesforce platform had become more intricate, with a growing number of custom objects, integrations, and business processes. This complexity made it increasingly challenging to maintain a comprehensive understanding of the entire system and its interdependencies.&nbsp;



Additionally, the client&#8217;s Salesforce development team was working at a fast pace, continuously introducing new features and updates to meet the evolving needs of their customers. While this agility was crucial for the business, it also created a constant state of change that made it difficult to ensure the stability and reliability of the Salesforce platform.



The client&#8217;s existing testing approach was heavily reliant on manual processes, which became increasingly time-consuming and error-prone as the Salesforce instance grew in complexity. The QA team struggled to keep up with the rapid development cycles, and they were unable to thoroughly validate all critical business scenarios before each deployment.&nbsp;



The manual testing approach simply could not scale to meet the demands of the client&#8217;s growing Salesforce ecosystem. As the number of test cases and the frequency of deployments increased, the QA team found it increasingly challenging to maintain the necessary testing coverage and ensure the quality of the Salesforce solutions.



These challenges led to delayed time-to-market, as the inefficient testing process and the inability to quickly identify and resolve defects impacted the client&#8217;s ability to deliver new features and updates to their customers. This had a direct impact on their competitive positioning and customer satisfaction.



The leadership team at the client&#8217;s organisation recognized that these challenges were hindering their ability to fully leverage the power of Salesforce and deliver the best possible experience to their customers. They knew that a more efficient and scalable testing approach was needed to overcome these obstacles and position the company for long-term success.



<h2 id="h-the-solution-comprehensive-salesforce-test-automation">The Solution: Comprehensive Salesforce Test Automation</h2>

Salesforce Automation Case Study: A Data-Driven Approach to Quality and Efficiency

As technology and industry become more complex, so does software. Any app or site being developed must now cater to the preferences and needs of people from different regions, demographic segments and life experiences. To make sure that people with such differing requirements get what they want out of an app or website, Quality Assurance engineers need to perform something called Extensive Testing.

<h2 id="h-what-is-extensive-testing">What is Extensive Testing?</h2>



Extensive testing, also known as exhaustive testing, involves verifying a software program’s response to all input combinations. Like the name suggests, it requires QAs to run all input combinations into the system and monitor results.&nbsp;



You test the software exhaustively – every function, every UI element, every UX metric. This technique provides a 360-degree analysis of the app’s functionality and user experience. It is directly responsible for improving software efficiency and usability for end-users.&nbsp;



It’s important to understand that you can never test every possible scenario, simply because that is impossible to predict. There will always be a minor user scenario left untested, but comprehensive testing will ensure that the flaws left behind are not big enough to affect UX.



However, modern extensive testing comes very close to eliminating all bugs but attacking the system with every possible input variable. Needless to say, it’s a time-consuming technique, but it produces bug-free software.



<h2 id="h-how-to-perform-extensive-testing">How to Perform Extensive testing</h2>



The following strategies are commonly deployed as part of an extensive testing approach:



<ul><li>Monitor the application’s recovery rate through self-analysis by the dev team. Functions with high recovery require less testing than the ones with low recovery. </li><li>Run <a href="https://testsigma.com/regression-testing" target="_blank" rel="noreferrer noopener">regression tests</a> after every bug fix to validate that all functions are working as expected after any system changes. </li><li>Run risk assessments on the application to estimate how certain low-recovery functions can impact other <a href="https://en.wikipedia.org/wiki/Software_component" target="_blank" rel="noreferrer noopener">software components</a>. These are the functions that require a closer look via extensive testing. </li><li>Look at all previous tests and narrow in on the features that are most likely to fail. The failing modules are the ones that require extensive testing. </li><li>Use ad-hoc testing and break down testing for individual modules to detect minor defects. </li><li>Reach out to stakeholders (analysts, product managers, customer support personnel) – and get reviews on the app’s workings. This will add more perspective to your quality control operations. </li><li>Use focus testing to craft relevant user scenarios for more precise, targeted testing. </li><li>Revise and refresh test cases for every test that requires different variables. Since extensive testing requires pushing all input variables, this is an essential step.&nbsp;</li></ul>



<h2 id="h-when-should-you-make-test-automation-a-part-of-extensive-testing">When should you Make Test Automation a Part of Extensive Testing?</h2>



You should incorporate test automation into your extensive testing plans when you come across the following scenarios in your <a href="https://en.wikipedia.org/wiki/SDLC" target="_blank" rel="noreferrer noopener nofollow">SDLC</a>:



<ul><li>When the project requires QAs to run a large number of repetitive tests, such as regression testing. Some tests require the same user actions, but with different input values each time. These tests can also, for the most part, be automated. <gwmw style="display:none;"></gwmw></li><li>When it’s most cost effective to automate the extensive tests. Manually testing every or most features of an application would require hiring a large number of testers. It would also take these testers more time to finish their tasks, because humans move slower than machines. Without automation, releasing software would take many more weeks or months – leading to a longer time to market and killing the app’s competitive value. </li><li>When you need to scale up your testing capacity by running tests simultaneously or in parallel. Most modern QA teams, even large ones, can only do so much in a few weeks with running <a href="https://testsigma.com/parallel-test-runs" target="_blank" rel="noreferrer noopener">parallel tests</a>. Automation engines like TestSigma are required to empower QAs and get more done in a short measure of time. </li><li>When you cannot afford to be undone by human error from tired and overworked testing. Extensive testing requires extensive work. Manually testers cannot be expected to stay up for days on end, scan through software functions and provide 100% accurate results. However, this is a common expectation from a test automation tool. It does not get tired and it does not make mistakes.&nbsp;</li></ul>

<h2 id="h-summary">Summary</h2>



Extensive testing is the last line of defense against major bugs in any software system. It casts a wide net for bugs, anomalies and errors that may tarnish user experience for end-users. It is the final filter in <a href="https://testsigma.com/guides/quality-assurance/" target="_blank" rel="noreferrer noopener">Quality Assurance</a> processes – a time-consuming filter with multiple techniques and strategies to eliminate as many software issues as humanly possible.&nbsp;



<h2 id="h-frequently-asked-questions">Frequently Asked Questions</h2>



<h3 id="h-when-should-you-perform-extensive-testing">When should you perform extensive testing?</h3>



Extensive testing should be the final step in the testing cycle. After all other tests have been executed, extensive testing comes in to validate the entire software system. Of course, it is possible to insert elements or techniques of extensive testing at different intervals within the testing pipeline. For example, insert regression tests after every major bug fix, perform risk assessments before testing commences, use focused testing to zero in on sensitive software areas, etc.&nbsp;
