Internal leaks are typically diagnosed using a leak-down tester, not a compression tester. A compression tester can indicate that there's a problem with the engine's ability to build pressure, but a leak-down tester is specifically designed to pinpoint where the leaks are occurring (e.g., through the valves, piston rings, or head gasket).
