Investigate test run issues

Oct 13, 2025 by wbrum.org 142 views

Introduction

In this article, we will investigate a workflow job that failed on the main branch of a repository. The job in question is the e2ePerformanceTests / Run E2E tests in AWS device farm. This job is responsible for running end-to-end tests on AWS device farm. However, a recent merge appears to have caused a failure in this job. In this article, we will analyze the failure summary, identify the potential causes of the failure, and provide a plan to address any underlying issues.

Failure Summary

The job failed with the following error message:

warning: No matching artifact of type LOG found for debug.log, skipping
failure: Test run failed after 235 seconds with: undefined. Timeout is set to 7200
warning: No matching artifact of type LOG found for debug.log, skipping

failure: Process completed with exit code 1.

Action Required

A recent merge appears to have caused a failure in the job named e2ePerformanceTests / Run E2E tests in AWS device farm. This issue has been automatically created and labeled with Workflow Failure for investigation.

Investigating the Failure

To investigate the failure, we need to answer the following questions:

Why the PR caused the job to fail?
Address any underlying issues.

Why the PR Caused the Job to Fail?

The PR that caused the job to fail is PR Link. The PR author is @SzymczakJ, and the PR was merged by @luacmartins. To understand why the PR caused the job to fail, we need to analyze the changes made in the PR.

Addressing Underlying Issues

To address any underlying issues, we need to identify the potential causes of the failure. Based on the error message, it appears that the job failed due to a timeout. The timeout is set to 7200 seconds, which is equivalent to 2 hours. The job failed after 235 and 265 seconds, which is significantly less than the timeout period.

There are several potential causes of the failure:

Insufficient resources: The job may not have had sufficient resources to complete the test run within the timeout period.
Test run issues: There may have been issues with the test run itself, such as a faulty test or a problem with the test environment.
Code changes: The recent merge may have introduced code changes that caused the job to fail.

To address these issues, we need to:

Verify the resources: Verify that the job had sufficient resources to complete the test run within the timeout period.
Investigate test run issues: Investigate the test run issues to determine if there were any problems with the test or the test environment.
Review code changes: Review the code changes made in the recent merge to determine if they caused the job to fail.

Conclusion

In this article, we investigated a workflow job that failed on the main branch of a repository. The job in question is the e2ePerformanceTests / Run E2E tests in AWS device farm. We analyzed the failure summary, identified the potential causes of the failure, and provided a plan to address any underlying issues. By following this plan, we can identify the root cause of the failure and take corrective action to prevent similar failures in the future.

Recommendations

Based on our investigation, we recommend the following:

Verify the resources: Verify that the job had sufficient resources to complete the test run within the timeout period.
Investigate test run issues: Investigate the test run issues to determine if there were any problems with the test or the test environment.
Review code changes: Review the code changes made in the recent merge to determine if they caused the job to fail.
Address any underlying issues: Address any underlying issues that may have caused the job to fail.

By following these recommendations, we can ensure that the job runs successfully and that the end-to-end tests are executed correctly.

Introduction

In our previous article, we investigated a workflow job that failed on the main branch of a repository. The job in question is the e2ePerformanceTests / Run E2E tests in AWS device farm. We analyzed the failure summary, identified the potential causes of the failure, and provided a plan to address any underlying issues. In this article, we will provide a Q&A section to answer some of the most frequently asked questions related to this issue.

Q&A

Q: What is the cause of the job failure?

Q: Why did the job fail after 235 and 265 seconds?

A: There are several potential causes of the failure, including:

Insufficient resources: The job may not have had sufficient resources to complete the test run within the timeout period.
Test run issues: There may have been issues with the test run itself, such as a faulty test or a problem with the test environment.
Code changes: The recent merge may have introduced code changes that caused the job to fail.

Q: How can I verify the resources?

A: To verify the resources, you can check the job's logs to see if there were any issues with the resources. You can also check the job's configuration to ensure that it has sufficient resources to complete the test run.

Q: How can I investigate test run issues?

A: To investigate test run issues, you can check the job's logs to see if there were any issues with the test run. You can also check the test environment to ensure that it is properly configured.

Q: How can I review code changes?

A: To review code changes, you can check the recent merge to see if there were any changes that may have caused the job to fail. You can also check the code changes to ensure that they are correct and do not introduce any issues.

Q: What are the next steps to address the issue?

A: The next steps to address the issue are:

Verify the resources: Verify that the job had sufficient resources to complete the test run within the timeout period.
Investigate test run issues: Investigate the test run issues to determine if there were any problems with the test or the test environment.
