FAQPage Schema
How do I set up integration tests in ASP.NET Core with a real database?▼

ASP.NET Core integration tests can use real database instances by leveraging testcontainers for Postgres provisioning, ensuring robust and deterministic test coverage for your application logic.

What is the best way to write expressive assertions for .NET unit tests?▼

Expressive assertions for .NET unit tests are achieved using FluentAssertions, providing a natural syntax to validate results rapidly and ensure high code quality and reliability.

Can I use xUnit with WebApplicationFactory for automated dotnet testing?▼

xUnit works seamlessly with WebApplicationFactory to execute automated dotnet testing, handling both unit and integration scenarios to verify application logic and gate CI pipelines.

Does this approach support deterministic tests for .NET applications?▼

Deterministic tests for .NET applications are fully supported by combining xUnit, WebApplicationFactory, and testcontainers, ensuring reliable execution without flaky behavior during integration testing.

Why use testcontainers for Postgres instead of mocks in dotnet integration tests?▼

Using testcontainers for Postgres provides a real database environment in dotnet integration tests, eliminating mock maintenance and verifying actual database interactions for higher reliability.

How do I automate dotnet testing to gate my CI pipeline?▼

Automating dotnet testing to gate your CI pipeline involves executing unit and integration tests with xUnit and testcontainers, ensuring only verified code passes quality checks.
