Example 36 with FilterChain

use of com.linkedin.r2.filter.FilterChain in project rest.li by linkedin.

the class TestRestReplayFilter method testReplayWithRestException.

@Test

    // Record a response for the request we will fire
    getDb().record(req, res);
    // We should be able to fire just the request - the response should be replayed from the
    // capture we set up above. The response should be a RestException since the status code is 404.
