Using Behave with Trunk Flaky Tests

You can automatically detect and manage flaky tests in your projects running Behave by integrating with Trunk. This document explains how to configure Behave to output JUnit XML reports that can be uploaded to Trunk for analysis.

Setup steps

Work through the steps below in order. Once you’ve finished the last one, you’ll be ready to move on to configure uploads in CI.

Generate a compatible test report

Configure the report file path or glob

Test uploads locally

Generating Reports

Trunk detects flaky tests by analyzing test results automatically uploaded from your CI jobs. Behave can output JUnit XML reports which are compatible with Trunk. You can do so with the --junit option:

behave --junit

Report File Path

You can customize the file path of the reports using the --junit-directory option.

behave --junit --junit-directory ./junit-reports

Behave outputs multiple XML reports under the JUnit directory. You can locate these when uploading the reports in CI with the "./junit-reports/*.xml" glob.

The Validate Command

You can validate your test reports using the Trunk Analytics CLI. If you don’t have it installed already, you can install and run the validate command like this:

SKU="trunk-analytics-cli-x86_64-unknown-linux.tar.gz"
curl -fL --retry 3 \
  "https://github.com/trunk-io/analytics-cli/releases/latest/download/${SKU}" \
  | tar -xz

chmod +x trunk-analytics-cli
./trunk-analytics-cli validate --junit-paths "./junit-reports/*.xml"

SKU="trunk-analytics-cli-aarch64-unknown-linux.tar.gz"
curl -fL --retry 3 \
  "https://github.com/trunk-io/analytics-cli/releases/latest/download/${SKU}" \
  | tar -xz

chmod +x trunk-analytics-cli
./trunk-analytics-cli validate --junit-paths "./junit-reports/*.xml"

SKU="trunk-analytics-cli-aarch64-apple-darwin.tar.gz"
curl -fL --retry 3 \
  "https://github.com/trunk-io/analytics-cli/releases/latest/download/${SKU}" \
  | tar -xz

chmod +x trunk-analytics-cli
./trunk-analytics-cli validate --junit-paths "./junit-reports/*.xml"

SKU="trunk-analytics-cli-x86_64-apple-darwin.tar.gz"
curl -fL --retry 3 \
  "https://github.com/trunk-io/analytics-cli/releases/latest/download/${SKU}" \
  | tar -xz

chmod +x trunk-analytics-cli
./trunk-analytics-cli validate --junit-paths "./junit-reports/*.xml"

This will not upload anything to Trunk. To improve detection accuracy, you should address all errors and warnings before proceeding to the next steps.

Test Upload

Before modifying your CI jobs to automatically upload test results to Trunk, try uploading a single test run manually. You make an upload to Trunk using the following command:

./trunk-analytics-cli upload --junit-paths "./junit-reports/*.xml" \
    --org-url-slug <TRUNK_ORG_URL_SLUG> \
    --test-collection-id <TRUNK_TEST_COLLECTION_ID> \
    --token <TRUNK_ORG_TOKEN>

You can find your Trunk organization slug and token in the settings or by following these instructions. The collection ID identifies the test collection the results belong to, and you copy it from that collection in the Trunk app. After your upload, you can verify that Trunk has received and processed it successfully in the Uploads tab. Warnings will be displayed if the report has issues.
