Vitest Python Packages

cartoon

Token-optimized output for any CLI — your AI agent reads 12 lines instead of 800, raw log always archived. Adapters for pytest/jest/vitest/ruff/eslint/tsc + a compression ladder for everything else.

testguard-cli

Claim-driven mutation testing: inject faults and report what your tests miss. Vitest, Jest, Playwright, pytest & unittest. Part of the Guard family with DocGuard and WebSec Validator.

mcp-assert

The testing standard for MCP servers. Lint (14 rules), test, and fuzz over real stdio/SSE/HTTP transport. 18 assertion types in YAML. Found 4,794 schema issues across 55 servers. Any language, no mocks, single binary.

pr-witness

Runs the base branch's tests against a PR's code and checks the description's claims against what actually ran. Signed evidence from CI.

pytest-mcp-assert

The testing standard for MCP servers. Lint (14 rules), test, and fuzz over real stdio/SSE/HTTP transport. 18 assertion types in YAML. Found 4,794 schema issues across 55 servers. Any language, no mocks, single binary.

executable-stories-pytest

Tests that document. Reports that convince. Write BDD stories inside your test framework. Generate living documentation your whole team can read.

reviewgate

A code review gate that verifies changes by executing tests, not by judging diffs. LLM proposes; a deterministic gate decides.

edgeverdict

A code review gate that verifies changes by executing tests, not by judging diffs. LLM proposes; a deterministic gate decides.

unfaked

Your agent said it's done. unfaked checks whether it made that true, or just made the check pass. Zero dependencies, no LLM.
