  • Test cases include specific inputs already defined and mentioned in the Test Case document and results generated against them to make sure the particular feature is working correctly or not.
  • Test engineers can use these variables or conditions to match expected results with the actual results to conclude whether the software application or product is operating under the client requirements or not.
