running-tests

running-tests is a cursor rule for Cursor from prisma/prisma-next. It costs 899 tokens per session, scanned A, a copy of running-tests, Apache-2.0.

A set of project test-running instructions for running suites, finding failures, and rerunning selected tests. It also covers logging, time limits, and build or type-check commands.

In plain words
What is it for?
Running unit, integration, and end-to-end tests; checking failures; rerunning targeted tests; building packages; and type-checking code.
Why use it?
It keeps slow test commands from blocking the agent and records each run's output and exit status in a known log file.

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

running-tests 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 3d 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 running-tests — 6 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.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

How to run tests, check for failures, and get specific failures

1. Run a test suite

Each slow command has an :agent variant. The first line of its output prints the exact log path:

$ pnpm test:packages:agent
log: wip/test-packages.20260615-190441.32317.log

The full output goes to that file. The exit code is written to a sibling .exit file (same path with .log.exit). Use the path printed by the command — don't guess one. Every run gets its own timestamped path, so history is preserved automatically. Contents of wip/ are gitignored.

Each :agent run has a hard timeout (default 5 minutes, override with AGENT_CMD_TIMEOUT_SECONDS — bump it for a legitimately long suite). If the run hangs — e.g. vitest freezes after printing its summary — the child process group is killed and the .exit file records 124 rather than blocking forever.

Command Purpose
pnpm test:packages:agent Unit tests for every package
pnpm test:integration:agent Integration suite (PGlite + mongodb-memory-server)
pnpm test:e2e:agent End-to-end suite
pnpm build:agent Build every package (turbo)
pnpm typecheck:agent Typecheck every package (turbo, cached)
pnpm lint:agent Biome lint
pnpm lint:deps:agent Dependency-layering check
pnpm fixtures:check:agent Regenerate fixtures and diff them

2. Run one package's tests

pnpm --filter @prisma-next/cli test

Runs only that package's own test script — seconds, not minutes. Output goes to your terminal; no capture needed.

3. Rerun a specific failing test

By file:

pnpm --filter @prisma-next/cli test test/commands/migration-list-json-golden.test.ts

By test name within a file (vitest's -t filter):

pnpm --filter @prisma-next/cli test test/commands/migration-list-json-golden.test.ts -t "pins head ref decoration"

4. Find specific failures in the captured output

Use the log path the :agent command printed (the shell exit status tells you pass/fail; the .exit sibling file records the same number). If non-zero, list failing files and assertions:

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.
