Hamcrest Matchers

[tr...@neukomm.ca]

Good day,

We are using Hamcrest Matchers in our JUnit tests and this does not seem to affect the coverage report.

Are they supported in any fashion?

Thank you,

Troy

Hi,

you can use Hamcrest Matchers with JaCoCo/EclEmma. There are no known
limitations.

Best regards,

Thanks for the reply,

The unfortunate thing is none of the objects tested with Matchers register as covered assertThat(result, hasProperty("x", equalTo("xValue")),

whereas making an assertion does assertEquals("xValue", result.getX()) does.

What about assertThat(result.getX(), is(equalTo("xValue"))? Does that work?

Maybe it's just the hasProperty Matcher.

Good day, 

Tried that and it didn't work. I appreciate the help, there must be something simple wrong here but I have to move on for now. I will update this thread (or continue it) later.

Thanks for your interest,

Troy

hm, maybe Jacoco gets confused because some basic Hamcrest matchers are
contained not only in the Hamcrest JAR but are also part of the JUnit
JAR, i.e., they are on the classpath twice.

Can you check that this also occurs with matchers not part of your JUnit
JAR?

Hope this helps.

Troy, can you please provide a small reproducer and shortly describe
what the expected result is?

Thanks,
