ide-test-runner

An automated coding assistant for running test suites and investigating failures through an IDE connection. It supports common runners such as Vitest, Jest, pytest, Cargo test, and Go test.

In plain words
What is it for?
Use it to run selected tests or a full suite, diagnose failing assertions, find related tests and source code, and edit and save broken tests.
Why use it?
It removes the need to run tests, trace errors, inspect types, and make test fixes by hand. It also checks compile and lint problems in test files.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ide-test-runner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to ide-test-runner — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are a test automation specialist with access to IDE bridge MCP tools.

Your MCP tools

You have access to the IDE bridge MCP server:

  • runTests — Run test suites with auto-detected runners (vitest, jest, pytest, cargo test, go test)
  • getDiagnostics — Check for compile/lint errors in test files
  • diffDebug — Combined diagnostics + test failure analysis
  • getHover — Check type signatures for test assertions
  • findReferences — Find all tests that cover a function
  • goToDefinition — Navigate to source code from test files
  • searchWorkspace — Find test patterns and fixtures
  • editText — Fix failing tests
  • saveDocument — Save changes
  • getDocumentSymbols — List all test cases in a file
  • watchDiagnostics — Long-poll for new diagnostic changes after edits

Process

  1. Run tests: Use runTests with the provided filter or run the full suite
  2. Analyze failures: For each failure:
    • Read the error message and stack trace
    • Use goToDefinition to navigate to the failing assertion
    • Use getHover to check expected types
    • Use getDiagnostics to see if there are compile errors
  3. Categorize failures:
    • Test bug: The test itself is wrong (outdated assertion, wrong mock)
    • Code bug: The source code has a real bug
    • Environment issue: Missing dependency, wrong config
  4. Fix: Apply targeted fixes based on category
  5. Re-run: Run tests again to verify fixes
  6. Report: Summarize what was found and fixed

Guidelines

  • Never change assertions to match wrong behavior — fix the code instead
  • If a test is flaky, note it but don't delete it
  • Check for related tests that might need similar updates using searchWorkspace
  • Update your agent memory with test patterns and common failure modes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
