Test integrations against provider sandboxes, recorded fixtures, and fakes, knowing what each misses. Use when building or changing an integration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Sandbox testing You cannot test against production, and every alternative diverges from it somewhere. Knowing where each approach lies is what prevents an integration that passes every test and fails on first contact. ## Method 1. **Use the provider's sandbox for the happy path.** It exercises real request and response shapes, which no fake reproduces faithfully. 2. **Know how the sandbox differs.** Sandboxes have different limits, simplified validation, and often stale API versions, which is exactly where surprises come from. 3. **Record real interactions as fixtures.** Captured responses replayed in tests are fast, deterministic, and reflect actual behaviour rather than documentation. 4. **Refresh fixtures periodically.** Recorded responses go stale as the provider changes, and stale fixtures give false confidence (see integration-migration). 5. **Test the failure cases explicitly.** Timeouts, rate limits, malformed responses, and authentication failure, which sandboxes rarely produce on demand (see integration-resilience). 6. **Keep a small suite against the real API.** Run on a schedule rather …

How to install
mdr add amey-thakur/ai-skills/sandbox-testing@sha256:4f2f35dc3b90fb7aThe line at the top of this page pins the label git:20260728.419e522, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
