Complete Guide to Unit Testing in .NET Core (NUnit & XUnit)

Write your first unit test using mstest, following arrange, act, and assert to test the calculator's add numbers with 10 and 20 and expect 30.

Set the same namespace for the Sparky main project and its unit tests, then create your first NUnit test using TestFixture and Test, following arrange, act, and assert.

Add a boolean odd-number checker method to the calculator class. Create two unit tests: odd input returns true, even input returns false, using NUnit or XUnit in .NET Core.

Master string assertion helpers in .NET unit testing with NUnit and XUnit. Use equality checks, containment, starts with, ends with, ignore case, and regex matches to validate output strings.

Use a global setup method with a setup attribute to initialize a shared customer object for all tests, removing duplicated code.

Explore collection helper methods in unit testing for .net core with nunit and xunit, including equality, contains, count, is ordered, and is unique.

create a grading calculator class, implement score and attendance logic, and build five unit tests (four specific cases and one multi-input case) to validate grades.

Write and run the first unit test for the fibo series in a .NET Core project, using an arrange, act, and assert pattern and assertions to verify output.

Examine a product price flow where platinum customers receive a 20% discount via get price, and validate the result with unit tests while warning against unnecessary interface mocks.

Implement log to db and log balance after withdrawal, returning booleans based on balance checks, and unit test this withdrawal and logging logic in .NET Core with NUnit and XUnit.

Explore how to configure default return values in mock setups, validate withdrawal scenarios with balances, and use range checks to simulate negative inputs in unit tests.

Convert the gradient calculator to x unit test by uncommenting the code and completing the conversion, gaining practical x unit practice. Pause the video, then continue in the next video.

convert the product unit test to xunit, remove comments, add using statements, and use equal assertions to verify the result equals 40.

Convert bank account unit tests from NUnit to XUnit in net core, using fact, theory, and inline data to verify get balance and equality assertions.

Describe a four-project .net core architecture (web project, three class libraries) with repository pattern and EF Core, including models, view models, seeding, and service-driven booking flow for unit testing.

Create a class library for unit tests targeting the bongo dot models project and install NUnit, NUnit3TestAdapter, and Microsoft.NET.Test.Sdk for the test framework. Test the date in future validation attribute by asserting that now plus 100 seconds is valid and now minus 100 seconds is invalid.

Explore how shared database state makes unit tests fail when run together, and fix it with an in-memory Entity Framework Core DbContext, test order, and database cleanup.

Develop unit tests for the room booking controller in .NET Core using NUnit and XUnit, mocking the study room booking service and verifying the index action invokes get all booking.
