=== Code examples

==== Noncompliant code example

[source,csharp,diff-id=1,diff-type=noncompliant]
----
[TestMethod]
[ExpectedException(typeof(ArgumentNullException))]  // Noncompliant
public void Method_NullParam()
{
    var sut = new MyService();
    sut.Method(null);
}
----

==== Compliant solution

[source,csharp,diff-id=1,diff-type=compliant]

[TestMethod]
public void Method_NullParam()
{
    var sut = new MyService();
    Assert.ThrowsException<ArgumentNullException>(() => sut.Method(null));
}
