### Question:
ParametersFromProperties implements HTTPRecordingParameters { @Override public boolean isMirroredHeader(String headerName) { return m_mirroredHeaders.contains(headerName); } ParametersFromProperties(); @Override int getTestNumberOffset(); @Override boolean isCommonHeader(String headerName); @Override boolean isMirroredHeader(String headerName);  }### Answer:
@Test public void testIsMirroredHeader() { final HTTPRecordingParameters parameters = new ParametersFromProperties(); assertTrue(parameters.isMirroredHeader("Accept")); assertTrue(parameters.isMirroredHeader("User-Agent")); assertTrue(parameters.isMirroredHeader("If-None-Match")); }
