Docs Integrations REST API Back to Testmo

Cucumber

Testmo works with any test automation tool, including the Cucumber behavior-driven development (BDD) testing framework. This quickstart guide provides an overview of how to report Cucumber test automation results to Testmo to implement Cucumber test management.

Cucumber comes with full support for generating JUnit-style XML files, which has become a standard format to exchange test results between tools. This works with all languages and platforms supported by Cucumber.

Java, Ruby & Kotlin

You can simply use the built-in junit formatter of Cucumber to generate the relevant XML files.

$ cucumber --format junit --out results/test-results.xml

This will run your tests with Cucumber and automatically write all test results to an XML file in the results directory. You can also learn more in the Cucumber documentation.

JavaScript

For JavaScript-based Cucumber tests, you can install the popular cucumber-junit package and use this to generate the XML files.

$ npx cucumber-js --format=json | npx cucumber-junit > test-results.xml

You can also find additional command line options in the package documentation.

To submit your test results to Testmo, you simply use our cross-platform testmo CLI tool. The CLI tool is distributed as an NPM package and is easy to install on any system. Simply install our official @testmo/testmo-cli NPM package:

$ npm install -g @testmo/testmo-cli
$ testmo -h

Usage: testmo [options] [command]
[...]

We can now send the Cucumber test results to Testmo. To do this, make sure to generate an API key in Testmo from your profile page. The API key is used to authenticate with Testmo to send the results. We can then use the testmo CLI tool so submit our results (note that we first set the TESTMO_TOKEN variable, which the tool expects):

$ export TESTMO_TOKEN=********
$ testmo automation:run:submit \
  --instance https://<your-name>.testmo.net \
  --project-id 1 \
  --name "Cucumber test run" \
  --source "unittests" \
  --results results/*.xml
See command output
Collecting log files ..
Found 1 result file with a total of 855 tests
Created new automation run (ID: 254)
Created new thread (ID: 608)
Sending tests to Testmo ..
Uploading: [|||||||||||||||||||||||||] 100% | ETA: 0s | 855/855 tests
Successfully sent tests and completed run
Marked the run as completed

That's it! 🎉 This will automatically analyze the XML result file, create a new test run in Testmo, submit all tests & results and mark the run as completed. There's no need to manually create any tests, map tests or IDs or build any custom API code. Everything is handled automatically for you.

In the above example, we first launched Cucumber to generate the XML file and then used our CLI tool to submit the results in a second step. As an improvement to the above example, we can ask our CLI tool to launch Cucumber (testmo then starts and waits for Cucumber to finish). This has the following additional benefits:

a) Capture full console output and send it to Testmo b) Accurately measure test times c) Record the Cucumber exit code

Launch Cucumber with CLI tool

We can ask our CLI tool to launch Cucumber, so we can capture the console output and more:

$ export TESTMO_TOKEN=********
$ testmo automation:run:submit \
  --instance https://<your-name>.testmo.net \
  --project-id 1 \
  --name "Cucumber test run" \
  --source "unittests" \
  --results results/*.xml \
  -- cucumber --format junit --out results/test-results.xml
    ^ space!

Also learn more and see other examples in the full Testmo CLI guide.

Now that you are familiar with submitting your Cucumber test results to Testmo, you might also find the following additional examples, topics and references useful for more advanced workflows.
