FAQPage Schema

How do I write data-driven unit tests in C# using TUnit?▼

TUnit data-driven unit tests in C# are implemented using inline, method-based, and class-based data source attributes. These constructs allow you to feed multiple test scenarios into a single test method for comprehensive coverage.

What is the best way to migrate xUnit tests to TUnit?▼

To migrate xUnit tests to TUnit, map equivalent test constructs such as facts and theories to TUnit's corresponding attributes. This Skill maps xUnit constructs to TUnit equivalents to streamline framework migration.

How do you write fluent asynchronous assertions in TUnit?▼

Fluent asynchronous assertions in TUnit use a chained API to validate test outcomes. This approach allows you to verify asynchronous operations robustly without manual event synchronization.

Does TUnit support parallel execution and test retries?▼

TUnit supports parallel execution and test retries for C# unit tests. These advanced features handle flaky tests by repeating execution and running tests concurrently to optimize suite performance.

How do I skip a test conditionally in TUnit?▼

Conditional skipping in TUnit is achieved using built-in attributes that bypass test execution dynamically. This ensures tests are only run when specific runtime conditions are met.
