What is xUnit in the context of .NET?
Antwoord
xUnit is an open-source unit testing framework for .NET, inspired by JUnit and NUnit. It uses attributes like [Fact] for simple tests and [Theory] for parameterized tests. xUnit encourages best practices like test isolation (each test creates a new test class instance) and avoids shared state via traditional Setup/Teardown methods.
2What is the difference between [Fact] and [Theory] in xUnit?
What is the difference between [Fact] and [Theory] in xUnit?
Antwoord
[Fact] decorates a simple test that runs once without parameters, while [Theory] decorates a parameterized test that runs multiple times with different values provided via [InlineData], [MemberData], or [ClassData]. Using [Theory] avoids code duplication when testing multiple similar scenarios with different data.
3How to use [InlineData] with [Theory] in xUnit?
How to use [InlineData] with [Theory] in xUnit?
Antwoord
[InlineData] provides data directly in the attribute for a [Theory] test, allowing the same test to run with different values. Each [InlineData] attribute represents a distinct test case. This approach is ideal for testing multiple simple scenarios without creating separate data classes, reducing boilerplate code.
