Catch

Testmo works with any test automation tool, including the popular Catch2 unit testing framework for C++. This quickstart guide provides an overview of how to report Catch test automation results to Testmo.

Run Catch & generate XML file

Catch comes with full support for generating JUnit-style XML files, which has become a standard format to exchange test results between tools.
$ test --reporter junit --out test-results.xml
This will run your tests with Catch and automatically write all test results to an XML file called test-results.xml. You can also configure a different directory or add any other standard Catch command line arguments. You can learn more about the junit reporter in the Catch documentation.

Submit test results to Testmo

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 Catch 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):
Full example
Single line
Windows
$ export TESTMO_TOKEN=********
$ testmo automation:run:submit \
--instance https://<your-name>.testmo.net \
--project-id 1 \
--name 'Catch test run' \
--source 'unittests' \
--results *.xml
If you run this example on a single command line, make sure to remove the backspaces:
$ export TESTMO_TOKEN=********
$ testmo automation:run:submit --instance https://<your-name>.testmo.net --project-id 1 --name 'Catch test run' --source 'unittests' --results *.xml
On Windows, the command line uses a slightly different syntax to set a variable:
> set TESTMO_TOKEN=********
> testmo automation:run:submit --instance https://<your-name>.testmo.net --project-id 1 --name 'Catch test run' --source 'unittests' --results *.xml
See command output
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.

Bonus: Launch Catch with Testmo CLI

In the above example, we first launched Catch 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 Catch (testmo then starts and waits for Catch 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 Catch exit code
