Drone CI
Configure Flaky Tests using Drone CI
Trunk Flaky Tests integrates with your CI by adding a step in your Drone CI 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.
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 your Trunk slug and API token in your Drone CI project settings as new variables named TRUNK_ORG_SLUG
and TRUNK_TOKEN
respectively.
Upload to Trunk
Add an upload 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
.
You must upload tests from both PR and stable branches, such as main
, master
, or develop
in CI for Trunk to detect flaky tests. Trunk will not detect flaky tests without uploads from both PR and stable branches.
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 report files the uploader needs, see the instructions for your test framework in the Test Frameworks docs.
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.
