Test Execution Internals

This document explains tests.cmd internals and helps troubleshoot test execution issues.

Overview

The test execution chain:

tests.cmd → Bazel → IdeaUltimateRunTestsBuildTarget → TestingTasksImpl → JUnit 5

Key components:

• tests.cmd: Shell script that invokes Bazel with test parameters
• Bazel target: //build:local_idea_ultimate_run_tests_build_target
• TestingOptions: Parses -Dintellij.build.test.* system properties
• TestingTasksImpl: Orchestrates classpath assembly and JVM setup
• JUnit runners: Execute tests in a forked JVM process
