  • By default, the following paths are used:
    • maven: src/test/java
    • rspec: spec/**/*_spec.rb
• launchable.testListCommand: The command to output the full list of tests, e.g. find ./test -name '*.js'.
  • By default, the following commands are used:
    • go-test: go test -list . ./...
    • pytest: [PYTHON PATH] -m pytest --collect-only -q
      • [PYTHON PATH] is configured by Python: Select Interpreter command.
• launchable.subsetPath: The path to the file that is a subset of tests
• launchable.testReportPath The path to your test report files, e.g. ./reports/*.xml
  • By default, the following paths are used:
    • maven: target/surefire-reports/*.xml
• launchable.testRunCommand: The command to run tests
  • By default, the following commands are used:
    • maven: mvn test -Dsurefire.includesFile=[SUBSET FILE]
    • rspec: bundle exec rspec $(cat [SUBSET FILE]) --format d --format RspecJunitFormatter --out [TEST REPORT PATH]
    • go-test: go test -run $(cat [SUBSET FILE]) ./... -v 2>&1 | go-junit-report > [TEST REPORT PATH]
    • pytest: [PYTHON PATH] -m pytest --junit-xml=[TEST REPORT PATH] $(cat [SUBSET FILE])
      • [PYTHON PATH] is configured by Python: Select Interpreter command.

You can configure a subset optimization target in the following fields. If you want to know the concept, please read here.

• launchable.optimizationTarget.confidence: Confidence target
• launchable.optimizationTarget.fixedTime: Fixed time target
• launchable.optimizationTarget.percentageTime: Percentage time taget
  • percentageTime field is configured as "80%" in the default.
