### Question:
TemplatedPayloadGenerator implements PayloadGenerator, Configurable { @Override public Map<String, String> getRequestParameters() { return requestParameterValues; }  @Override void configure(Map<String, ?> props); @Override boolean update(Request request, Response response); @Override String getRequestBody(); @Override Map<String, String> getRequestParameters(); @Override Map<String, String> getRequestHeaders(); @Override Map<String, Object> getOffsets(); @Override void setOffsets(Map<String, Object> offsets);  }### Answer:
@Test public void testGetRequestParameters() { System.setProperty("PRIORITY", "MAXIMUM"); System.setProperty("PAGED", "FALSE"); generator.configure(CONFIG_PROPS); assertThat(generator.getRequestParameters(), allOf( hasEntry("priority", "MAXIMUM"), hasEntry("paged", "FALSE"))); }
