java - Mock Files with PowerMockito -



java - Mock Files with PowerMockito -

i have next test code:

@runwith(powermockrunner.class) @preparefortest({logger.class, files.class}) public class testclass { private static final list<string> list = new arraylist<string>() {{ add("some entry"); }}; private static final path path = paths.get("/tmp/foo"); @before public void setup() { powermockito.spy(files.class); powermockito.doreturn(list).when(files.class, "readalllines", path, charset.defaultcharset()); } @test public void test() {} }

the code above throws "nosuchfileexception" on lastly line. here stacktrace:
