+description: Run tests for a specific SDK module. Use when asked to "run tests", "test module", "run unit tests", "run system tests", "run e2e tests", or test a specific class. Auto-detects unit vs system tests. Supports interactive mode.

+
+# Run Tests
+
+Run tests for a specific module. Auto-detects whether to run unit tests or system tests.
+
+## Step 0: Check for Interactive Mode
+
+If `$ARGUMENTS` starts with `interactive` (e.g., `/test interactive sentry ScopesTest`), enable interactive mode. Strip the `interactive` keyword from the arguments before proceeding.
+
+In interactive mode, use AskUserQuestion at decision points as described in the steps below.
+
+## Step 1: Parse the Argument
+
+The argument can be either:
+- A **file path** (e.g., `@sentry/src/test/java/io/sentry/ScopesTest.kt`)
+- A **module name** (e.g., `sentry-android-core`, `sentry-samples-spring-boot-4`)
+- A **module name + test filter** (e.g., `sentry ScopesTest`)
+
+Extract the module name and optional test class filter from the argument.
+
+**Interactive mode:** If the test filter is ambiguous (e.g., matches multiple test classes across modules), use AskUserQuestion to let the user pick which test class(es) to run.
+
+## Step 2: Detect Test Type
+
+| Signal | Test Type |
+|--------|-----------|
+| Path contains `sentry-samples/` | System test |
+| Module name starts with `sentry-samples-` | System test |
+| Everything else | Unit test |
+
+## Step 3a: Run Unit Tests
+
+Determine the Gradle test task:
+
+| Module Pattern | Test Task |
+|---------------|-----------|
+| `sentry-android-*` | `testDebugUnitTest` |
+| `sentry-compose*` | `testDebugUnitTest` |
+| Everything else | `test` |
+
+**Interactive mode:** Before running, read the test class file and use AskUserQuestion to ask:
+- "Run all tests in this class, or a specific method?" — list the test method names as options.
+
+If the user picks a specific method, use `--tests="*ClassName.methodName"` as the filter.
+
+With a test class filter:
+```bash
+./gradlew ':<module>:<task>' --tests="*<filter>*" --info
+```
+
+Without a filter:
+```bash
+./gradlew ':<module>:<task>' --info
+```
+
+## Step 3b: Run System Tests
+
+System tests require the Python-based test runner which manages a mock Sentry server and sample app lifecycle.
+
+1. Ensure the Python venv exists:
+```bash
+test -d .venv || make setupPython
+```
+
+2. Extract the sample module name. For file paths like `sentry-samples/<sample-module>/src/...`, the sample module is the directory name (e.g., `sentry-samples-spring`).
+
+3. Run the system test:
+```bash
+.venv/bin/python test/system-test-runner.py test --module <sample-module>
+```
+
+This starts the mock Sentry server, starts the sample app (Spring Boot/Tomcat/CLI), runs tests via `./gradlew :sentry-samples:<sample-module>:systemTest`, and cleans up afterwards.
+
+## Step 4: Report Results
+
+Summarize the test outcome:
+- Total tests run, passed, failed, skipped
+- For failures: show the failing test name and the assertion/error message
