# tests\e2e\docker\docker-entrypoint.test.ts @source-hash: 18113ac79ba05773 @generated: 2026-02-23T15:26:00Z ## Purpose End-to-end regression test for Docker container entrypoint argument passing. Specifically validates that CLI arguments are correctly passed without character corruption (fixes a bug where printf-generated entry.sh produced literal `\"` characters breaking SSE mode). ## Test Configuration - **Test Suite**: `'Docker: Entrypoint Argument Passing'` (L22-94) - **Environment Controls**: `SKIP_DOCKER` flag bypasses tests if Docker unavailable (L19) - **Image Configuration**: Uses `DOCKER_IMAGE_NAME` env var or defaults to `'mcp-debugger:local'` (L20) - **Setup**: `buildDockerImage()` builds test image before all tests (L23-25) ## Test Cases ### Version Command Test (L27-41) Validates `--version` argument passes cleanly without corruption: - Runs `docker run --rm ${IMAGE_NAME} --version` - Expects version output (semver pattern `/\d+\.\d+/`) - Rejects error messages indicating argument corruption ### SSE Help Command Test (L43-57) Validates `sse --help` subcommand argument passing: - Runs `docker run --rm ${IMAGE_NAME} sse --help` - Expects SSE help output containing `-p` option and `sse` text - Rejects unknown option errors ### SSE Mode Integration Test (L59-93) Full integration test starting SSE server with port argument: - Creates temporary container with `sse -p 3001` command - Validates container remains running (doesn't exit on arg corruption) - Checks logs for absence of argument parsing errors - Includes proper cleanup with container stop/remove ## Dependencies - **Vitest**: Test framework (L12) - **Node.js**: `child_process.exec` for Docker commands (L13-14, L17) - **Docker Utilities**: `buildDockerImage()` from `./docker-test-utils.js` (L15) ## Key Test Pattern All tests use `execAsync()` (promisified `exec`) with timeouts to run Docker commands and validate output/behavior. The tests are designed to catch a specific regression where shell quoting bugs caused CLI arguments to contain literal quote characters.
