xUnit Theory InlineData code example

Example 1: c# xunit theory classdata model

[Theory]
[ClassData(typeof(CarClassData))]
public void CarTest(Car car)
{
     var output = car;
     var result = _myRepository.BuyCar(car);
}

Example 2: xunit theory inlinedata complex object

public class StringTests2
{
    [Theory, PropertyData(nameof(SplitCountData))]
    public void SplitCount(string input, int expectedCount)
    {
        var actualCount = input.Split(' ').Count();
        Assert.Equal(expectedCount, actualCount);
    }

    public static IEnumerable<object[]> SplitCountData
    {
        get
        {
            // Or this could read from a file. :)
            return new[]
            {
                new object[] { "xUnit", 1 },
                new object[] { "is fun", 2 },
                new object[] { "to test with", 3 }
            };
        }
    }
}

Example 3: c# xunit theory classdata model

public class CarClassData : IEnumerable<object[]>
    {
        public IEnumerator<object[]> GetEnumerator()
        {
            yield return new object[] {
                new Car
                {
                  Id=1,
                  Price=36000000,
                  Manufacturer = new Manufacturer
                  {
                    Country="country",
                    Name="name"
                  }
                }
            };
        }
        IEnumerator IEnumerable.GetEnumerator() => GetEnumerator();
    }
