Mocking a URL in Java

Question

We have a URL object in one of our Java classes that we want to mock, but it\'s a final class so we cannot. We do not want to go a level above, and mock the InputStream beca

Answer 1

I have used a URLHandler that allows me to load a URL from the classpath. So the following

new URL("resource:///foo").openStream()

would open a file named foo from within the class path. To do this, I use a common utility library and register a handler. To use this handler, you just need to call:

com.healthmarketscience.common.util.resource.Handler.init();

and the resource URL is now available.
