Class InlineAutoDataAttribute
Namespace: AutoFixture.Xunit2
Assembly: AutoFixture.Xunit2.dll
Provides a data source for a data theory, with the data coming from inline values combined with auto-generated data specimens generated by AutoFixture.

Constructors
InlineAutoDataAttribute(params object[])
Initializes a new instance of the InlineAutoDataAttribute class.
public InlineAutoDataAttribute(params object[] values)Parameters
values object[]
The data values to pass to the theory.
InlineAutoDataAttribute(DataAttribute, params object[])
Initializes a new instance of the InlineAutoDataAttribute class.
protected InlineAutoDataAttribute(DataAttribute autoDataAttribute, params object[] values)Parameters
autoDataAttribute DataAttribute
An DataAttribute.
values object[]
The data values to pass to the theory.
Examples
In this example, TheAnswer is a Customization that changes all 32-bit integer values to 42. This behavior is encapsulated in MyCustomAutoDataAttribute, and transitively in MyCustomInlineAutoDataAttribute. A parameterized test demonstrates how it can be used.
[Theory]
[MyCustomInlineAutoData(1337)]
[MyCustomInlineAutoData(1337, 7)]
[MyCustomInlineAutoData(1337, 7, 42)]
public void CustomInlineDataSuppliesExtraValues(int x, int y, int z)
{
Assert.Equal(1337, x);
// y can vary, so we can't express any meaningful assertion for it.
Assert.Equal(42, z);
}

}
private class MyCustomAutoDataAttribute : AutoDataAttribute

base(() => new Fixture().Customize(new TheAnswer()))
{

private class TheAnswer : ICustomization

public void Customize(IFixture fixture)
{

}
}
}Remarks
This constructor overload exists to enable a derived attribute to supply a custom `DataAttribute` that again may contain custom behavior.
