A checkpoint is a verification point that compares the current value with the expected value for specified properties of an Object. If they current and expected value match it generates a PASS status otherwise FAIL status}
There are many types of checkpoints detailed below
- Standard checkpoints: It compares the expected values of object properties captured during recording to the object's current values during a run session
- Page Checkpoint : A Standard Checkpoint created for a web page can be called a Page Checkpoint. It is used to check total number of links & images on a web page. Page Checkpoints can be used to check Load Time i.e. time taken to load a web page.
- Bitmap Checkpoint helps a user in checking the bitmap of an image or a full web page. It does a pixel by pixel comparison between actual and expected images.
- Image Checkpoint enable you to check properties like source file location of a web image. Unlike , Bitmap Checkpoint you can not check pixels(bitmaps) using image checkpoint.
- Text Checkpoint is Used to check expected text in a web-page or application. This text could be from a specific region of the application or a small portion of text displayed
- Accessibility Checkpoints verifies compliance with World Wide Web Consortium (W3C) instructions and guidelines for Web-based technology and information systems. These Guidelines make it easy for disabled to access the web.
- Database Checkpoints create a query during record time and database values are stored as expected values. Same query is executed during run time and actual & expected values are compared.
- In Table Checkpoint , you dynamically can check the contents of cells of a table (grid) appearing in your environment. You can also check various table properties like row height , cell width and so on. Table Checkpoint is similar to Database Checkpoint
- Using XML Checkpoints you can verify XML Data ,XML Schema, XML Data
Following Videos gives steps to create a Standard Checkpoint
Takeaways from the Video
- You may have notice that results generated for our test script has no Pass/ Fail Status without which our automation is incomplete
- The expected TEST RESULT for our scenario should be - Flight Reservation Window which is this screen should appear after entering valid username and password. To accomplish this we will need to record an additional step # 6 which is Check Flight Reservation Window is Displayed..
- Automation of this verification step can be achieved using Checkpoints. Lets go ahead and record step # 6 To add a checkpoint , right click on the step # 5 after which checkpoint needs to be inserted .Choose Insert Standard Checkpoint. Checkpoint Properties Dialog Box Opens.
- QTP assigns a default name to checkpoint. You can input your preferred name
- The table shows all the recorded properties and their corresponding values for the object. The Selection mark indicates that these properties will be checked
- ABC icon indicated that the property values are a constant. If you parameterize any of the selected properties the icon changes correspondingly
- Lets stick to the default and insert the statement after the current step. Click okay
- A check statement with checkpoint name is inserted at line # 6.Lets replay the script
- The script gives a Run-Time Error
- Well this is a common source of error for beginners and happens because at step # 5 , QTP closes the Flight Reservation Screen and when the execution reaches step # 6 there is no Flight Reservation Screen Object available to very its properties. You need to ensure , that the object which are verifying is available while QTP executes the Checkpoint Step
- This error can be rectified by changing the sequence of Tests Steps. You need to switch Step 5 & step 6 . In the new scenario step 5 is verify the Flight Reservation Window Exists and step 6 is to Close the application
- In QTP , you just need to cut step # 6 and paste it at location of step # 5.Lets replay the script again. The Script passes and the results tree gives the checkpoint values that were compared. That's all to standard checkpoints
