Cross-language testing strategies and patterns. Triggers on: test pyramid, unit test, integration test, e2e test, TDD, BDD, test coverage, mocking strategy, test doubles, test isolation.
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
# Testing Patterns
Universal testing strategies and patterns applicable across languages.
## The Test Pyramid
```
/\
/ \ E2E Tests (few, slow, expensive)
/ \ - Full system tests
/------\ - Real browser/API calls
/ \
/ Integ \ Integration Tests (some)
/ Tests \ - Service boundaries
/--------------\ - Database, APIs
/ \
/ Unit Tests \ Unit Tests (many, fast, cheap)
------------------ - Single function/class
- Mocked dependencies
```
## Test Types
### Unit Tests
```
Scope: Single function/method/class
Speed: Milliseconds
Dependencies: All mocked
When: Every code change
Coverage: 80%+ of codebase
```
### Integration Tests
```
Scope: Multiple components together
Speed: Seconds
Dependencies: Real databases, mocked external APIs
When: PR/merge, critical paths
Coverage: Key integration points
```
### End-to-End Tests
```
Scope: Full user journey
Speed: Minutes
Dependencies: Real system (or staging)
When: Pre-deploy, nightly
Coverage: Critical user flows only
```
## Test Naming Convention

How to install
mdr add aiskillstore/marketplace/testing-patterns@sha256:47db1c978c35153eThe line at the top of this page pins the label git:20260113.222b7de, 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.
