| xUnit | (none — convention-based) | [Fact], [Theory] |
| NUnit | [TestFixture] |
[Test], [TestCase], [TestCaseSource] |
| TUnit | [ClassDataSource] |
[Test] |
Assertion APIs by Framework
| Category | MSTest | xUnit | NUnit |
|---|---|---|---|
| Equality | Assert.AreEqual |
Assert.Equal |

| Boolean | Assert.IsTrue / Assert.IsFalse |
Assert.True / Assert.False |
