MatrTech.Utilities.Test

This package provides some utilities to make it easier to test in C#. For starters it provides a lightweight dependency factory to manage all the tests dependencies. Making it easily and safe to register and replace dependencies within each test. Which provides proper state to test against.

Installing

The package is easily installed using nuget.

Install-Package MatrTech.Utilities.Test

Using the package

using namespace Matr.Test;

{
    factory.RegisterOrReplace(new Mock<ITestDependency>().Object);
}

[SetUp]
public void Init()
{
    factory.RegisterOrReplace(new Mock<ITestDependency>().Object);
}

Using in tests

MSTest

[TestMethod]
public void TestMethod()
{
    // Setup test specifc dependencies.
    var mockedDependency = new Mock<ITestDependency>();
    
    // Mock functionality specific to the test.
    mockedDependency.Setup(...).Returns(...);

    // Register test specifc dependencies.
    factory.RegisterOrReplace(mockedDependency.Object);
    
    // Create your service with the Create method.
    // This will resolve all dependencies.
    var serviceToTest = factory.Create<ServiceToTest>();
    
    var result = serviceToTest.MethodToTest();

    Assert.Equal(result, expectedValue);
}

NUnit

Same goes for NUnit

[Test]
public void TestMethod()
{
    // Setup test specifc dependencies.
    var mockedDependency = new Mock<ITestDependency>();
    
    // Mock functionality specific to the test.
    mockedDependency.Setup(...).Returns(...);

    // Register test specifc dependencies.
    factory.RegisterOrReplace(mockedDependency.Object);
    
    // Create your service with the Create method.
    // This will resolve all dependencies.
    var serviceToTest = factory.Create<ServiceToTest>();
    
    var result = serviceToTest.MethodToTest();

    Assert.Equal(result, expectedValue);
}
