How to assertThat something is null with Hamcrest?

How would I assertThat something is null?

for example 

 assertThat(attr.getValue(), is(""));

But I get an error saying that I cannot have null in is(null).

Solution

  • You can use IsNull.nullValue() method:

    import static org.hamcrest.Matchers.is;
import static org.hamcrest.core.IsNull.nullValue;


assertThat(attr.getValue(), is(nullValue()));
