Docs Integrations REST API Back to Testmo

GoogleTest

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

GoogleTest comes with full support for generating JUnit-style XML files, which has become a standard format to exchange test results between tools.

$ test --gtest_output "xml:test-results.xml"

This will run your tests with GoogleTest 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 GoogleTest command line arguments. You can learn more about the junit reporter in the GoogleTest 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 GoogleTest 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 "GoogleTest test run" \
  --source "unittests" \
  --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.

➡️ Bonus: Launch GoogleTest with Testmo CLI

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

Launch GoogleTest with CLI tool

We can ask our CLI tool to launch GoogleTest, 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 "GoogleTest test run" \
  --source "unittests" \
  --results *.xml \
  -- test --gtest_output "xml:test-results.xml" 
    ^ space!

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