Convention-aware testing

Tests that match your project's style, not generic AI output. Testbench reads your existing tests before generating anything — extracting import style, mock patterns, assertions, and naming conventions. Generated tests are indistinguishable from hand-written ones. Self-healing: runs, fixes, and retries up to 3 times.

/testbench:calibrate

Test Framework Calibration

Detects test framework (Vitest, Jest, Playwright, Cypress, pytest, Go test, Cargo test, RSpec, PHPUnit). Reads conventions. Generates config.

Queries Context7 for framework docs
Extracts conventions from existing test files automatically

/testbench:generate

Convention-Aware Generation

Generates tests for a single file. Reads config AND existing test files, never generates without context.

Categories: happy path → edge cases → error cases → type contracts
React: render, content, interactions, conditional rendering, accessibility
API routes: successful response, validation, auth, authz, not found
Auto-splits if exceeding 150 lines
Runs test and fixes up to 3 times before declaring failure

/testbench:run

Test Runner

Runs tests with scope control: all, changed files only, or single-file. Parses output, extracts failures with source context.

Supports Vitest/Jest/pytest/Go/Cargo output formats
Coverage analysis with Composure graph integration
Identifies high-impact untested functions by caller count
