This MCP server provides tools to automate the verification of code changes. It identifies only the tests affected by specific file modifications, minimizing execution time. By comparing current results against a historical baseline, it detects new failures, removed tests, and non-deterministic flakiness. Use run_targeted_tests to execute specific suites, get_test_baseline to retrieve previous successful states, and analyze_regression_differences to perform deep comparisons between runs.

3 tools expose this connector's capabilities to your AI agent.

analyze_regression_differences

Performs a deep comparison between the current test run results and the baseline

run_targeted_tests

Executes the specific subset of tests identified as being affected by the provided file changes

get_test_baseline

Retrieves the recorded results of the last successful or most recent relevant test run

See how to talk to your AI agent using test-regression-runner.

Run the tests affected by the changes in src/logic.ts.

Tests for src/logic.ts have been executed. Status: PASS. 12 tests passed, 0 failed.

Compare my current test results with the baseline for suite 'core-api'.

Comparison complete. 1 new failure detected in 'auth_test.spec.ts'.

Get the baseline for the 'ui-components' suite.

Baseline retrieved: lastPassCount: 45, lastFailCount: 0, lastCoverage: 88.5%.

The system maps modified source files to their corresponding test files using naming conventions, ensuring only relevant tests are run via `run_targeted_tests`.
