Execute Jest tests on provided implementation and test files in an isolated workspace. Returns detailed test results including pass/fail status, individual test results, error messages, stack traces, and code coverage metrics.

Update the Jest configuration in a workspace by merging new settings with the existing config. Useful for adjusting coverage thresholds, test patterns, or other Jest options.

Retrieve a list of past test runs with optional filters by workspace, status, or date. Returns summaries of test runs including timestamps, workspace IDs, pass/fail status, and file names.

Retrieve the contents and metadata of a test workspace. Returns workspace metadata, list of files with their contents, and current Jest configuration.

Delete test workspace(s) and their associated history. Can delete a specific workspace by ID, or clean all old workspaces based on age. Returns a summary of deleted workspaces.

Retrieve complete details of a historical test run by history ID. Returns full test results, error messages, stack traces, and coverage data from a previous test execution. Useful for comparing test results across iterations, reviewing past failures, or analyzing coverage progression.

List all available test workspaces with their metadata. Returns workspace IDs, creation timestamps, language type, and file counts. Useful for discovering existing workspaces, understanding workspace organization, and managing workspace lifecycle.

Update an implementation file in an existing workspace and optionally run tests. This enables efficient iteration during the refactor phase of TDD without re-uploading test files. Automatically runs tests and saves results to history unless autoRunTests is false.

Add an additional test file to an existing workspace and optionally run all tests. Useful for adding edge case tests, integration tests, or additional test suites without re-uploading implementation code. Automatically runs all tests in the workspace unless autoRunTests is false.

Run a subset of tests in an existing workspace using Jest test name patterns or file path patterns. Useful for focused testing during debugging, running only failing tests, or testing specific functionality without running the entire suite. Supports Jest's -t flag for test names and file path patterns.
