BitBucket Pipelines

Trunk Flaky Tests integrates with your CI by adding a step in your BitBucket Pipelines to upload tests with the Trunk Uploader CLI.

Not using GitHub for source control?

Flaky Test support for source control providers like GitLab and BitBucket is still experimental. If you're using a source control provider other than GitHub, contact us to get started.

Before you start on these steps, see the Test Frameworks docs for instructions on producing a Trunk-compatible output for your test framework.

Checklist

By the end of this guide, you should achieve the following.

• Get your Trunk organization slug and token

• Set your slug and token as a variable in CI

• Configure your CI to upload to Trunk

• Validate your uploads in Trunk

After completing these checklist items, you'll be integrated with Trunk.

Trunk Organization Slug and Token

Before setting up uploads to Trunk, you must sign in to app.trunk.io and obtain your Trunk organization slug and token.

Trunk Slug

You can find your organization slug under Settings > Organization > Manage > Organization Name > Slug. You'll save this as a variable in CI in a later step.

Trunk Token

You can find your token under Settings > Organization > Manage > Organization API Token > View Organization API Token > View. Since this is a secret, do not leak it publicly. Ensure you get your organization token, not your project/repo token.

Add the Trunk Token as a Secret

Store the Trunk slug and API token obtained in the previous step in your BitBucket as a new variable named TRUNK_ORG_SLUG and TRUNK_TOKEN respectively.

Upload to Trunk

Add an after-script step after running tests in each of your CI jobs that run tests. This should be minimally all jobs that run on pull requests, as well as from jobs that run on your stable branches, for example, main, master, or develop.

It is important to upload test results from CI runs on stable branches, such as main, master, or develop. This will give you a stronger signal about the health of your code and tests.

Trunk can also detect test flakes on PR and merge branches. To best detect flaky tests, it is recommended to upload test results from stable, PR, and merge branch CI runs.

Add Uploader to Testing Pipelines

The following is an example of a workflow step to upload test results after your tests run. Note: you must either run trunk from the repo root when uploading test results or pass a --repo-root argument.

To find out how to produce the JUnit XML files the uploader needs, see the instructions for your test framework in the Test Frameworks docs.

            bundle exec rspec

See the Uploader CLI Reference for all available command line arguments and usage.

Stale files

Ensure you report every test run in CI and clean up stale files produced by your test framework. If you're reusing test runners and using a glob like **/junit.xml to upload tests, stale files not cleaned up will be included in the current test run, throwing off detection of flakiness. You should clean up all your results files after every upload step.

You can do this by omitting the artifacts definitions in the test steps of your configuration. Learn more about artifacts in BitBucket Pipelines.
