10 key metrics and KPIs for your test automation reporting

In today’s quickly changing world of software development, test automation has become a fundamental aspect of the process. Testing becomes faster and more efficient. To measure how well your test automation is working and how efficient it is, use clear metrics and key performance indicators in your reports. Together with our test automation reporting expert Zebrunner, we will share the top 10 best metrics and KPIs for measuring your testing success. 

Automation reporting overview

Test automation reporting involves systematically collecting, analyzing, and presenting data related to test automation processes. It enables teams to assess the effectiveness of their automation strategies and makAutomation reporting e data-driven decisions to enhance testing efficiency. 

Test automation reporting offers significant advantages. Here’s a simplified breakdown of these benefits:

  • Automated report generation. Test automation reporting streamlines the process of generating reports. Instead of manually compiling data and crafting reports, automation handles this task. This means you spend less time on manual paperwork and more time on actual testing and analysis.
  • Time-saving potential. With test automation reporting, your team can focus on essential tasks rather than spending excessive time on manual reporting. Automated generation of reports frees up resources, enabling testers and developers to concentrate on refining software quality and resolving issues.
  • Measuring essential testing metrics. Test automation reporting provides a mechanism to measure vital testing metrics accurately. These metrics offer insights into test coverage, execution efficiency, defect trends, and more. By assessing these metrics, you gain a clear understanding of your project’s testing status and quality.
  • Customizable widgets. Test automation reporting employs customizable widgets that visualize complex data in an easy-to-understand format. These widgets allow you to tailor the reporting to your project’s specific needs. Whether it’s a graph illustrating pass/fail rates or a pie chart showing defect distribution, these widgets provide a clear and concise overview.
  • Enhanced decision-making. Accurate and easily digestible reports resulting from test automation help stakeholders make informed decisions swiftly. Managers and team leads can rely on real-time data to assess progress, allocate resources effectively, and adjust strategies if necessary.

10 key metrics for automation reporting

Metrics help you track progress, identify bottlenecks, and assess the overall health of your testing efforts. By analyzing these metrics, teams can identify areas for improvement, make informed decisions, and ensure that their automation strategy aligns with project goals.

#1. Total test coverage

This metric assesses the extent to which your automated tests cover the various features and functionalities of your application. It’s crucial to achieve a high coverage rate to ensure that all critical aspects of your software are thoroughly tested. A comprehensive coverage rate minimizes the risk of undiscovered defects and provides confidence in the overall quality of your application.

Total test coverage = (Number of Features Covered / Total Number of Features) * 100

#2. Automated vs. Manual test ratio

The Automated vs. Manual Test Ratio reveals the balance between automated and manual tests in your testing strategy. Striking the right balance is essential. While automation offers efficiency and repeatability, manual testing adds the human touch to exploratory testing. Monitoring this ratio helps you make informed decisions about allocating resources effectively and optimizing your testing approach.

Automated vs. Manual test ratio = (Number of Automated Tests / Total Number of Tests) * 100

#3. Test execution time

Test execution time metric measures the duration it takes to run each automated test. Analyzing this metric helps identify slow-performing tests that might prolong your testing cycle. By optimizing or addressing these sluggish tests, you can significantly improve the efficiency of your test execution process, leading to faster feedback and quicker software iterations.

Test execution time = Time taken to execute a specific test

#4. Test failure rate

Test failure rate highlights the percentage of automated tests that fail during execution. A high failure rate could indicate issues with the application’s functionality or the quality of your test cases. By tracking this metric over time, you can identify problematic areas and prioritize fixing critical defects, thus enhancing the reliability of your software.

Test failure rate = (Number of Failed Tests / Total Number of Executed Tests) * 100

#5. Defect detection rate

This metric shows the effectiveness of your automated tests in uncovering defects before they reach production. A high defect detection rate indicates that your tests are successfully identifying issues early in the development process, reducing the cost and impact of defects on end users. This metric underscores the value of comprehensive and well-designed automated test suites.

Defect detection rate = (Number of Defects Caught by Automated Tests / Total Number of Defects) * 100

#6. Test maintenance effort

Test maintenance effort quantifies the time and effort invested in maintaining and updating your automated test scripts. Frequent changes in the application or test environment can lead to high maintenance effort. Minimizing this effort is essential to ensure that the maintenance burden doesn’t overshadow the benefits of automation. Refactoring and using robust automation frameworks can help manage this metric effectively.

Test maintenance effort = Time spent on maintaining and updating test scripts

#7. Test parallelization efficiency 

Test parallelization efficiency assesses how efficiently your tests can be run in parallel. Parallel execution minimizes test execution time and provides quicker feedback. Ensuring that your automated test suite is designed to take advantage of parallelization can significantly enhance the speed and efficiency of your testing process.

Test parallelization efficiency = (Total Test Execution Time without Parallelization / Total Test Execution Time with Parallelization) * 100

#8. Test environment availability

Test Environment Availability tracks the availability of necessary test environments for automation. Delays in obtaining required environments can disrupt your testing schedule. Maintaining a well-managed environment provisioning process ensures that your automated tests can run seamlessly, leading to consistent and timely testing.

Test environment availability = (Time Test Environment Available for Testing / Total Testing Time) * 100

#9. Test case duplications

Test case duplications measure the presence of duplicate test cases within your automation suite. Duplicate test cases can lead to redundancy and increased maintenance efforts. Regularly reviewing and eliminating duplicate tests improves the manageability of your suite, streamlining maintenance and reducing the risk of inconsistencies.

Test case duplications = (Number of Duplicate Test Cases / Total Number of Test Cases) * 100

#10. Test result trend

Test result trend analyzes historical test results over time. This metric helps you identify patterns and trends, allowing you to predict potential issues and assess the progress of your testing efforts. By spotting recurring patterns, you can proactively address challenges and continuously improve your testing strategy.
Test result trend = Analysis of historical test results over time
