Use when writing or wiring tests for a Pragmatic app, mocking a boundary or IClock, or when a generated contract test fails or is missing (Pragmatic.Testing, contract tests, WebApplicationFactory, Testcontainers).

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

# Pragmatic Use Testing

**Covers:** Test a Pragmatic app with Pragmatic.Testing: generated contract tests (authorization, CRUD, tenant isolation, transitions), a typed Api client, the real host under WebApplicationFactory with Testcontainers, test identities, assertions, generated mocks, clock/bus/mail/log harnesses.

A Pragmatic application already declares what it promises: endpoints, permissions, entities, state
machines. `Pragmatic.Testing` turns those declarations into tests, and the modules ship harnesses for
the parts a test has to control (time, the bus, mail). Write by hand only what a declaration cannot
say: the business rule.

## Three kinds of test, three projects

| Project | What it tests | Runs |
|---|---|---|
| `{App}.Tests` (unit) | Domain rules, handlers, services, with generated mocks | milliseconds, no container |
| `{App}.IntegrationTests` | The real host over HTTP against a real database; generated contract tests live here | Testcontainers (Docker) |

How to install

The exact contents, by fingerprint
mdr add pragmatic-design/pragmatic.design/pragmatic-use-testing@sha256:1bc252e48b53d9e9

The line at the top of this page pins the label git:20261017.dc88d60, 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.
