What is Check Point? How it is added to an application?

- Check point can be thought of as a point to confirm or verify whether the application under test or AUT is working properly or not. 

- This is verified by making comparisons between the current value of some property and the expected value of the same property decided earlier. 

- Whenever a check point is added by the user, an equivalent check point is added by the quick test professional to the present row in the key word view as well as a “check check point” statement is added to the expert view. 

- The name of the test object also serves as a name for the check point that has been added to it. 

- The check points can be added via an active screen by placing the cursor on the desired location and clicking the insert standard check point option. 

Types of Check Points

It is on the basis of this expected value that the check points have been classified in to various types as described below:

6. Data base check point: 

- This check point performs the task of generating a query while the recording is in progress. 

- The values stored in the data base serve as expected values. 

- This query is executed during the run time to obtain the actual value which is then compared with the expected value.
