Synopsis

Build ASP.NET Core applications you can test, refactor, and deploy with confidence.

A Web API may work perfectly today, but what happens after the next refactor, database migration, authentication change, or new feature?

Testing ASP.NET Core 10 Applications is a practical guide to building reliable automated tests for modern ASP.NET Core applications. As Book 4 of The Practical ASP.NET Core Series, it continues the WorkBoard API project and shows how to verify the application from individual business rules all the way to real HTTP, database, authentication, and production workflows.

Rather than focusing on test counts or chasing code-coverage percentages, this book teaches you how to choose the smallest realistic testing boundary that can prove the behavior that matters.

You will learn how to:

• Write clear and maintainable tests with xUnit

• Test business rules and application services

• Use fakes, stubs, and mocks without over-mocking

• Test asynchronous code and failure scenarios

• Build ASP.NET Core integration tests with WebApplicationFactory

• Send real HTTP requests using HttpClient

• Test status codes, validation, serialization, and ProblemDetails

• Verify filtering, sorting, pagination, and API contracts

• Test Entity Framework Core 10 with real SQL Server

• Run disposable database tests with Testcontainers for .NET

• Test database migrations, relationships, queries, and constraints

• Verify authentication, JWT tokens, roles, claims, and authorization policies

• Test resource ownership and cross-user security boundaries

• Build reusable fixtures, factories, and test-data builders

• Diagnose and prevent flaky tests

• Use code coverage effectively

• Run automated tests in continuous integration

• Build a dependable production regression strategy

Throughout the book, you will work with the practical WorkBoard API, using realistic testing scenarios instead of disconnected examples.

Who This Book Is For

This book is ideal for C# and ASP.NET Core developers who already understand basic Web API development and want to build more reliable, maintainable, and production-ready applications.

You do not need advanced testing experience. The concepts progress from focused unit testing to full application integration, SQL Server testing, security testing, and automated quality practices.

By the end of the book, you will understand not only how to write automated tests, but also what to test, where to test it, and how to build a test suite developers can actually trust.
