Testing Guide for IntelliJ IDEA

Comprehensive testing reference for running tests in the IntelliJ IDEA codebase.

Quick Start

Run a single test class (use FQN or wildcard - simple names don't work):

# Option 1: Fully qualified name (recommended)
./tests.cmd -Dintellij.build.test.patterns=com.example.MyTest

# Option 2: Wildcard prefix
./tests.cmd -Dintellij.build.test.patterns=*MyTest

Pattern Matching (CRITICAL)

Simple class names like MyTest do NOT work. You must use FQN or wildcard.
