Run tests in CI pipelines

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

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.

              - step:
                  type: Run
                  name: Pytest
                  identifier: Pytest
                  spec:
                    shell: Sh
                    command: |-
                      pytest test_main.py --junit-xml=output-test.xml
                    reports:
                      type: JUnit
                      spec:
                        paths:
                          - output-test.xml

For more information about configuring Run steps, go to Use Run steps.

Run Tests step

The Run Tests step is required to enable Test Intelligence. You can use Run Tests steps with or without Test Intelligence; however, this step requires that you use a supported codebase.

This example runs tests with Maven and Test Intelligence, and it produces a test report in JUnit XML format.

              - step:
                  type: RunTests
                  name: runTestsWithIntelligence
                  identifier: runTestsWithIntelligence
                  spec:
                    connectorRef: account.GCR
                    image: maven:3-openjdk-8
                    args: test -Dmaven.test.failure.ignore=true -DfailIfNoTests=false
                    buildTool: Maven
                    language: Java
                    packages: org.apache.dubbo,com.alibaba.dubbo
                    runOnlySelectedTests: true ## Set to false if you don't want to use Test Intelligence.
                    reports:
                      type: JUnit
                      spec:
                        paths:
                          - "target/surefire-reports/*.xml"

tip

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.
• Parallelism: You can use parallelism with either the Run or Run Tests steps to speed up test times. For more information, go to Speed Up CI Test Pipelines Using 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 sleep statements in your unit test code.
• Order your tests so that the tests most likely to fail come first.
