What methods and approaches will you use to implement testing in this project?

For testing in a C# project, the following approaches can be used:

• Unit Testing: testing individual methods and classes using frameworks such as NUnit, xUnit, or MSTest.

• Integration Testing: testing the interaction between components, for example, with a real database or external services.

• Mocking: using stubs and mock objects (e.g., with Moq) to isolate the components under test.

• Test Automation: integrating tests into the CI/CD process for regular execution.

Example of a simple unit test with NUnit:

[Test]
public void Add_TwoNumbers_ReturnsSum()
{
    var calculator = new Calculator();
    var result = calculator.Add(2, 3);
    Assert.AreEqual(5, result);
}
