Testing

A `[Test]` reaches the network for real — `Http.*` and a typed `client { }` operation both run inside a test, against the live endpoint. So a test…

A test in Osy# is not a unit test with the world mocked out. It is your app, running against its own throwaway database, with your security rules…

The assertions a test makes. Beyond the usual equality and null checks there are comparisons (Greater, Less, InRange), a regex check (Matches)…

Debugs one of your app's tests against a Platform on your own machine — breakpoints, stepping, and variable inspection in your editor — with no…

Runs your app's tests against a throwaway copy of its database, reporting each test as it finishes. Your local source is what runs, so you never have…

Runs your app's tests against a Platform on your own machine — no account, no network, no setup beyond a running local platform. `osyrin dev` starts…

Runs a block as a given principal, so security rules apply exactly as they would for that user. It is how you test that a rule denies the people it…
