NuGet Packages

ByteStudio.AutoFixture

Common interfaces, attributes, and AutoFixture customizations.

ByteStudio.AutoFixture.MSTest2

Adds AutoFixture support for MSTest V2 unit tests.

Example 1 - Create test method with an AutoFixture-generated argument.

[AutoData]
public void ShouldDoSomethingGivenSomeCondition(ClassUnderTest sut)
{
    // Arrange
    // sut is auto-generated by AutoFixture.
    
    // Act
    
    // Assert
    Assert.IsNotNull(sut);
}

Example 2 - Define parameters to run for test.

[AutoData]
[InlineData(1, 2, "buckle my shoe")]
public void ShouldDoSomethingElseGivenSomeCondition(int number1, int number2, string message, ClassUnderTest sut)
{
    // Arrange
    /*
     * number1, number2, and message are all assigned from the values defined in the [InlineData] attribute. 
     * Test method parameters that are not defined in [InlineData] are auto-generated by AutoFixture.
     */
    
    // Act
    
    // Assert
    Assert.AreEqual(1, number1);
    Assert.AreEqual(2, number2);
    Assert.AreEqual("buckle my shoe", message);
    Assert.IsNotNull(sut);
}

Example 3 - Define different sets of parameters to run for the same test.

[AutoData]
[InlineData(1)]
[InlineData(2)]
[InlineData(3)]
public void ShouldDoSomethingElseGivenAnotherCondition(int number, ClassUnderTest sut)
{
    // Arrange
    /*
     * number == 1 for first test run, 2 for the second test run, and 3 for the third test run.
     * Test method parameters that are not defined in [InlineData] are auto-generated by AutoFixture.
     */
    
    // Act
    
    // Assert
    Assert.IsNotEqualTo(0, number);
    Assert.IsNotNull(sut);
}

ByteStudio.AutoFixture.AutoMoq

Adds AutoMoq behavior to AutoFixture so interface dependencies are automatically mocked.

NOTE: If a parameter is an interface or has a dependency that is an interface, then [AutoMoq] must be added to the test method so AutoFixture knows how to generate a value.

Example 1 - AutoMoq interface test parameter.

[AutoData, AutoMoq]
public void ShouldDoSomethingGivenSomeCondition(IAmAnInterface dependency, ClassUnderTest sut)
{
    // Arrange
    // `dependency` will be automatically generated as a Mock.Of<IAmAnInterface>() instance.
 
    // Act
    
    // Assert
    Assert.IsNotNull(dependency);
}
