The ValueSource argument does not specify an existing member. This will lead to an error at run-time.
To prevent tests that will fail at runtime due to improper construction.
[Test]
public void NUnit1011SampleTest([ValueSource("MyIncorrectTestSource")] string stringValue)
{
Assert.That(stringValue.Length, Is.EqualTo(3));
}
public static object[] MyTestSource()
{
return new object[] {"One", "Two"};
}
In the example above, the test case source is named MyIncorrectTestCaseSource, but the test case source is actually
named MyTestSource. Because the names don't match, this will be an error.
Rename the TestCaseSource to match:
[Test]
public void NUnit1011SampleTest([ValueSource("MyTestSource")] string stringValue)
{
Assert.That(stringValue.Length, Is.EqualTo(3));
}
public static object[] MyTestSource()
{
return new object[] {"One", "Two"};
}
Or even better, use nameof so that the compiler may assist with mismatched names in the future:
[Test]
public void NUnit1011SampleTest([ValueSource(nameof(MyTestSource))] string stringValue)
{
Assert.That(stringValue.Length, Is.EqualTo(3));
}
public static object[] MyTestSource()
{
return new object[] {"One", "Two"};
}
Configure the severity per project, for more info see MSDN.
