@lbennett/transient-tantrum v1.1.0

@lbennett/transient-tantrum

Target a GitLab CI job to retry N times to find transient failures.

This CLI tool is intended to be used for MRs that include potential fixes for transient failures on GitLab CI.

If you think you have found a fix for a transient failure, you can retry the job a number of times to increase your confidence in the fix. This does replace debugging and understanding the fix.

As of v1.1.0, you can also invert the operation and retry on failure instead of success. This was not the original intended use, but it comes in handy with known flaky tests that have no immediate fix where all you can do is retry until your pipeline is green.

Installation

npm install --global @lbennett/transient-tantrum
#OR
yarn global add @lbennett/transient-tantrum

• retryCount: The number of times you would like to retry the job on success. Default: 5
• waitDuration: The duration in minutes to wait between checking the job status. Default: 3
• invert: Retry on failure instead of success Default: false

$ transient-tantrum -h
transient-tantrum <projectPath> <mergeRequestId> <jobName> [retryCount]
