You can run all types of tests in CI pipeline, including integration tests, functional tests, mutation tests, unit tests, and more.
To run tests in CI pipelines, you can use Run or Run Tests steps.
- Run step
- Run Tests step
You can run any type of test for any codebase in a Run step.
For example, this step runs
pytest and produces a test report in JUnit XML format.
pytest test_main.py --junit-xml=output-test.xml
For more information about configuring Run steps, go to Use Run steps.
This example runs tests with Maven and Test Intelligence, and it produces a test report in JUnit XML format.
args: test -Dmaven.test.failure.ignore=true -DfailIfNoTests=false
runOnlySelectedTests: true ## Set to false if you don't want to use Test Intelligence.
For more information about configuring Run Tests steps and Test Intelligence, go to Test Intelligence overview.
You can include code coverage commands in your Run and Run Tests steps.
Improve test times
These Harness CI features can improve test times:
- Test Intelligence: Test Intelligence speeds up your test cycles by running only the unit tests required to confirm the quality of the code changes that triggered a build. You must use the Run Tests step to enable Test Intelligence.
- Test splitting (parallelism): You can use parallelism with either the Run or Run Tests steps to speed up test times. For more information, go to Split tests (parallelism).
- Step groups: You can use step groups to organize and condense pipelines that run a lot of tests.
You might also try these test optimization practices:
- Use mock services in your unit tests, rather than setting up and connecting to third-party services. Mockups can often test your code as well as fully-running services but with fewer resources.
- Avoid integration tests in your build pipelines when possible. You might want to move these to a separate Pipeline.
- Look for obsolete tests that you can delete.
- Look for unnecessary
sleepstatements in your unit test code.
- Order your tests so that the tests most likely to fail come first.
You can view test results in Harness.
