code: public void check(String action, String expectedResult, String actualResult) {
          checks++;
          recordStep(action, expectedResult, actualResult, true, Success.CHECK);
      }
docs: Records the performed step as a check to the output file. A screenshot will be taken for traceability and debugging purposes.
  This includes the action taken if any, the expected result, and the actual result.
  If a 'real' browser is not being used (not NONE or HTMLUNIT), then no screenshot will be taken
  
  @param action         - the step that was performed
  @param expectedResult - the result that was expected to occur
  @param actualResult   - the result that actually occurred
