This guide provides comprehensive testing patterns for C# and .NET applications. It covers best practices using xUnit, FluentAssertions, and advanced techniques like mocking (NSubstitute/Moq), parameterized testing, and full integration testing using Testcontainers and WebApplicationFactory. Ideal for improving test quality, coverage, and developing robust, maintainable codebases.

A comprehensive guide covering best practices for writing effective unit tests using the TUnit framework for .NET. Topics include structuring tests using the Arrange-Act-Assert (AAA) pattern, implementing data-driven tests via attributes, utilizing fluent assertion syntax, managing complex test lifecycles (Class/Assembly level hooks), and migrating concepts from xUnit to TUnit. Learn how to write robust, isolated, and advanced tests.

Provides guidance on organizing and writing focused XUnit unit tests, covering project setup, fact/theory patterns, assertions, mocking, and data-driven testing for reliable .NET test suites.

Scaffolds an empty xUnit integration test project targeting Oracle in .NET solutions, including a transaction-rollback base class and seed data manager. Use in Phase 3 before writing Oracle baseline tests for Oracle-to-PostgreSQL migration.

Comprehensive patterns and tools for writing robust tests for F# applications within the modern .NET ecosystem. This guide covers unit testing (xUnit, FsUnit), property-based testing (FsCheck), mocking dependencies (NSubstitute), and full integration testing (WebApplicationFactory). Ideal for improving test coverage, validating complex business logic, and establishing a resilient testing infrastructure.

This skill provides a comprehensive test quality review, drawing on established principles from classic engineering texts like xUnit Test Patterns and How Google Tests Software. It diagnoses structural flaws—such as brittleness, decay, and poor coverage—in existing test suites, helping ensure that the codebase and its tests are robust, maintainable, and adhere to high industry standards.

This skill reviews test suite quality using established testing literature to identify brittleness, mock abuse, unclear fixtures, weak assertions, slow feedback, and maintenance risks. It diagnoses structural problems in existing test suites based on classic engineering books like xUnit Test Patterns and The Art of Unit Testing, ensuring robust and maintainable testing practices.

Reviews existing test suites for structural problems like brittleness, mock abuse, coverage illusions, slow runs, and poor readability, drawing on twelve classic engineering books such as xUnit Test Patterns and Working Effectively with Legacy Code.
