Resolving Jenkins UI Testing Suite Issues: Missing Test Result Trend Graph

Resolving Jenkins UI Testing Suite Issues: Missing Test Result Trend Graph

11 April 2024 Stephan Petzl Leave a comment Tech-Help

If you’re utilizing Jenkins for running UI Testing suites across various Xcode projects, you might encounter a scenario where the ‘Test Result Trend’ graph is not displayed for certain projects, despite seemingly correct configurations. This issue can be perplexing, especially when other projects are showing the graph without any problems.

Understanding the Test Result Trend Graph Display Criteria

The ‘Test Result Trend’ graph is a vital tool for monitoring the progress and stability of your test suite over time. It provides a visual representation of your test results, allowing you to quickly identify trends and anomalies. When this graph fails to appear, it can hinder your ability to track the performance of your tests effectively.

Common Configuration and Output Checks

  • Ensure that the project configurations are consistent, especially concerning the git repository location.
  • Verify that the console outputs do not indicate any errors that could affect the graph generation.
  • Confirm that the ‘test-reports/*.xml’ files are present and formatted correctly.

Solution to the Missing Test Result Trend Graph

If you have conducted the above checks and the issue persists, the solution may be related to the historical test results of your project:

Requirement for a Successful Test Run

For the ‘Test Result Trend’ graph to be displayed on the project’s job page in Jenkins, there must be at least one successful test run with 100% of the tests passed. In the absence of a successful test run, Jenkins will not generate the graph. This means that if all test runs have failed up to the current date, the graph will not be visible.

Steps to Resolve

  1. Review the history of your test runs for the specific project in question.
  2. Identify if there has been at least one completely successful test run.
  3. If all test runs have been failures, focus on fixing the tests to achieve a successful run.
  4. Once a successful test run is recorded, the ‘Test Result Trend’ graph should appear on the job page.

Addressing this issue requires a successful test run to unlock the visibility of the trend graph. It’s crucial to ensure that your test suite can pass entirely at least once so that Jenkins can start tracking the test results over time.

Additional Information

In addition to the primary solution, it’s worth noting that some users have reported the ‘Test Result Trend’ graph appearing only when there is a mix of both failed and successful tests. This behavior might vary depending on the specific plugins and configurations in use within your Jenkins setup.

To further investigate and resolve any inconsistencies with the display of the ‘Test Result Trend’ graph, consider exploring the configurations of the plugins you are using, such as the Xcode plugin and the JUnit test result plugin.

Conclusion

While it can be frustrating when the ‘Test Result Trend’ graph is not showing, understanding the criteria for its display is the key to resolving the issue. By ensuring that your project has at least one successful test run, you can enable the graph and continue to monitor your testing efforts effectively. Keep in mind that Jenkins’ behavior can vary with different plugins, so be prepared to adjust your approach based on your specific environment.
