How to access TestData from headless build [message #525271]

Hello,
In our SWTBot test plugin, we have a folder of Test Data that the test setups use to populate projects with data that can be used in the test. When running in the IDE this is great and in the test source code we can loadup files using a project relative path (e.g., new File ("TestData/mymodel.xml")

However when running headless in an exported product we have a problem in that these files cannot be accessed. They are included in the build, and the test plugin is unpacked, but the files cannot be read. Does anyone know how SWTBot test code can load up test data when the tests are being invoked headlessly and are embedded in an RCP app?

Thanks in advance,
Richard

Hi Richard,

What we do is ensure that the file is actually packed as part of the
build and then get an inputstream for it using SWTBot's FileUtils class:

bundle = Platform.getBundle('com.example.bundle');
internalUrl = bundle.getEntry('/path/to/file.txt');
url = FileLocator.resolve(internalUrl);
inputstream = url.openStream();

contents = FileUtils.read(inputstream);

There are a few other utility methods in FileLocator that you may find
useful.

Cheers!

I'm putting such resources along with my test classes on the class path, because that's
the only way I'm aware of loading resources independently from OSGi, f.e.:

TestResources.getStream("somefile.txt");

---

public class TestResources {

public static InputStream getStream(String filename) {
return TestResources.class.getResourceAsStream(filename);
}

}

Greetings,

Ralf

Thanks, that absolutely did the trick.
Since our app expects files, we write the stream
to tmp files and then cache the tmp file so the names are consistent through all tests

Cheers
Richard
