Vulthil.xUnit.Cosmos

Use Vulthil.xUnit.Cosmos to test against the Azure Cosmos DB emulator with Vulthil.xUnit.

When to use

• Integration tests for Cosmos-mapped EF Core contexts
• Sharing one emulator container across parallel test classes via a ContainerHost, with an emulator database per class

Pattern

• Derive CosmosTestContainerFixture<TDbContext> and supply the configuration key (optionally pin the emulator image via Configure)
• Register the fixture on the assembly's ContainerHost (or a factory) like any other container
• Let the fixture own database creation, per-test resets, and per-scope isolation — no scope plumbing in test code

See Testing for the full integration-testing guide.
