GitLab CI/CD

Testmo features extensive GitLab CI/CD integration to submit test automation results from your CI pipelines to implement GitLab test management. Integrating your automation tests only requires a few lines of code and is easy to set up. Any test automation tool, framework and platform can be used.

Also works with GitLab Issues

You can also integrate Testmo with GitLab Issues. Learn more about all GitLab integrations.

You can integrate simple GitLab CI/CD pipelines (such as running just a single test automation suite) as well as complex workflows with multiple test suites (e.g. frontend, backend, API etc.) and even parallel testing jobs with multiple threads.

Regardless of your specific configuration and workflow, the basic concept of integrating your GitLab CI/CD pipeline with Testmo is always the same:

You launch your GitLab CI/CD pipeline from Testmo
You execute your automated tests as part of your GitLab CI/CD workflow. It doesn't matter if you run a single test suite, multiple test suites or even parallel testing jobs.
You configure your automated tests to generate a result file using the standard JUnit XML file format. This file format has become the de facto standard format to exchange test results between testing tools. So practically any test automation tool and framework either supports this format directly or can convert to this format.
You then use the Testmo CLI tool to easily submit the results to Testmo, enabling you to track your test suites over time, identify problematic test cases and improve testing performance.

Basic GitLab CI/CD & Testmo workflow

The following GitLab CI/CD workflow shows how to execute a simple test automation run as part of your CI workflow and submit the test results to Testmo. In this example we are using a test suite with the Mocha/Chai (Node.js/Javascript) testing framework. Remember that you can use any test automation tool and framework with Testmo and we are just using this framework for our example.

We are using the Testmo CLI tool here as it makes it very easy to run our tests and submit all results with a single command line call (using the automation:run:submit command).

We are also sending a few additional fields to Testmo here, such as a link back to the GitLab CI/CD pipeline run as well as the Git commit hash. These details are then displayed in Testmo along with the test results, console output, exit code etc.

You can find the full code for this project on GitLab in the example project repository. You can also find a detailed explanation of this project along with more code samples and screenshots in our reference guide:

Guide: GitLab CI/CD Test Automation Pipeline & Reporting ➞

Important: For this code to work, it is required to define the variables TESTMO_TOKEN and TESTMO_URL in GitLab CI/CD with your Testmo address and API token as explained below.

Advanced GitLab CI/CD workflows

We also support advanced GitLab CI/CD workflows. For example, you can submit test results for many test suites from a GitLab pipeline run and Testmo also fully supports parallel test runs.

Running multiple test suites in a build If you have multiple test suites for your project (such as frontend, backend, API, mobile tests etc.) you can simply submit these as separate test runs from the same GitLab CI/CD pipeline. You would just use multiple calls to automation:run:submit to submit each test suite separately. Important: if you have different test suites, you need to use different source names for the test runs in Testmo. This way Testmo can differentiate where the test results are coming from. Learn more about test automation sources.
Using parallel testing jobs with GitLab CI/CD Testmo also fully supports tracking test runs with multiple parallel test jobs. So if you have configured your GitLab CI/CD workflow to run multiple parallel jobs to speed up your test execution, you can also submit each job as a separate thread of the same run to Testmo. You can learn more about implementing this in the following example.

GitLab CI/CD parallel testing workflow

Testmo comes with full support for GitLab CI/CD workflows with parallel testing jobs, so you can submit the results as separate threads of the same run to Testmo. You can then see the results (and console output, exit codes & testing times) of each thread separately, as well as the overall results and statistics for the entire test run in Testmo. The following illustration shows how to implement the workflow with GitLab CI/CD.

In this workflow we use separate jobs to set up our test run (test-setup), then submit a thread for each testing job of the run (test), and finally mark the test run as completed (test-complete).

We have a detailed guide with example code, screenshots and explanations on implementing this for GitLab CI/CD. You can also find a complete example project repository on GitLab. You can find the full guide here:

Important security considerations

When working with the Testmo API and CLI to submit test automation results to Testmo, you need to specify an API key for the authentication. You can learn more about generating API keys in Testmo here.

When integrating Testmo with your GitLab CI/CD pipelines, it is important not to store the API key in your code repository. If you store the API key in your code repository, everyone with access to the repository would be able to access the key. You should never add and store your Testmo API key as part of your code repository.

Instead, use GitLab's project variable feature to securely store keys and passwords. You can then make these secrets available as environment variables in your pipeline. You can see this in the example configuration above, as well as in our detailed GitLab CI/CD guide. You can also learn more about GitLab CI/CD project variables in the official documentation.
