Consider using the constraint model, Assert.That(actual, Is.LessThanOrEqualTo(expected)), instead of the classic
model, ClassicAssert.LessOrEqual(actual, expected).
The assert ClassicAssert.LessOrEqual from the classic Assert model makes it easy to confuse the expected and the
actual argument, so this analyzer marks usages of ClassicAssert.LessOrEqual.
[Test]
public void Test()
{
ClassicAssert.LessOrEqual(actual, expected);
}
The analyzer comes with a code fix that will replace ClassicAssert.LessOrEqual(actual, expected) with
Assert.That(actual, Is.LessThanOrEqualTo(expected)). So the code block above will be changed into.
[Test]
public void Test()
{
Assert.That(actual, Is.SameAs(expected));
}
Configure the severity per project, for more info see MSDN.
