How do I find out what Library a method is in?

Question

Specifically: what library is MockObjectTestCase in?

I'm following this link: http://therning.org/niklas/2005/05/jmock-solid-testing/

Is there an easy way to find out this kind of information? IS there a way to search through all of the files in the JMock jars?

I have jmock-2.5.1.jar, jmock-junit4-2.5.1.jar, junit-4.10.jar in my build path, but eclipse is not finding MockObjectTestCase as a super class selection for me to extend

Thanks

In your case the package seems to be: org.jmock.cglib.MockObjectTestCase

And according to http://www.jarfinder.com/index.php/java/info/org.jmock.MockObjectTestCase It seems to be found in 1.x versions of Jmock.

That post you linked to seems very old. Since you're using a later version that class might not exist anymore.

What exactly did you google? Just MockObjectTestCase? That gives the link to the javadoc:http://www.jmock.org/javadoc/2.0.0/org/jmock/integration/junit3/MockObjectTestCase.html Is the library in the javadoc? – Eric Francis Apr 30 '12 at 21:14
@ericf Sorry about that, I've updated with another link. I doubt that the class exist in jmock-2.5.1. – Simon Forsberg Apr 30 '12 at 21:24
I also noticed a program called JarClassFinder. It is nice. – Eric Francis Apr 30 '12 at 21:30
For further reference, where did you find the class you were looking for? – Simon Forsberg Apr 30 '12 at 22:15

I use findjar for this sort of thing. In your case:

http://www.findjar.com/index.x?query=MockObjectTestCase

Click on any of the results (i have no idea why there are so many - the links all lead to the same place), and you get a list of jars. Click through from those, and you have some information about the jars.

I suspect both findJAR and jarFinder are mostly indexing artefacts from Maven Central. You can search that directly:

http://search.maven.org/#advancedsearch|gav

Which in your case:

http://search.maven.org/#search|ga|1|c%3A%22MockObjectTestCase%22

Finds quite a number of results.

Google works well. But sometimes you have to revert to the data you have on your disk:

jar tf SomeJarFile.jar | grep ClassName

Iterate over all your jars.
