Using API tooling to search for test cases [message #523322]

Hi,

quite often when encountering a bug in some Eclipse class I wanted to search for all uses
of this class to find test cases which cover the class. I learned at EclipseCon that such
searches might be executed using the API tooling. I found this mentioned on the wiki (
http://wiki.eclipse.org/PDE/API_Tools/Use_Cases#API_Usage_Re porting_.28Batch_Mode.29 ,
http://wiki.eclipse.org/PDE/Plan/3.6#API_Use_Scans ) but found no documentation / howto.
Did I miss anything here? Is there an easy way to find all usages of some class in all
Eclipse code and locate test code for classes/methods this way?

Greetings,

Ralf

Trying to find all the usage of particular Java member in your workspace, it might be better to use the JDT command for finding all references in your workspace.

To use the API tooling to extract references please start with the wiki here: http://wiki.eclipse.org/PDE/API_Tools/Resources, which gives a pretty good howto for using the UI and the Ant tasks

the problem is that I'm trying to find something that is not in my workspace or target
platform yet - I'm just trying to find the project I want to check out :) I'm looking for
a way to go from a class like "org.eclipse.swt.Button" to the unit tests that use this
class, without having all the plug-ins that have unit test classes in my workspace. I'm
just trying to make contributing to Eclipse easier and "provide an easy way to find
existing tests" was one of my ideas that I'm investigating.

thanks for the starting point; but I was looking more for a way to search existing
metadata about references in all the Eclipse projects (like an pre-calculated index which
class uses which other class, or even full-text search would be a good start), not for a
way to generate reports. I guess API Tooling doesn't provide such an index; I'll try to
set this up for an existing project and see what I can get from it...

Greetings,

Ralf
