Scenario

For an Assistance Request case, when users enter the make of a vehicle, one or more associated vehicles are displayed in the Vehicle list. Users report that when they enter the vehicle information during the Submit request process, some vehicle makes do not display an associated vehicle in the list. Stakeholders want to ensure that at least one vehicle is related to the value of the Make field. 

In addition, stakeholders are concerned about application performance. To ensure customers can complete Assistance Request cases efficiently, stakeholders want the vehicle list to generate within 200 milliseconds.

As the application developer, ensure that the data page returns the Vehicle list and determine whether the list is generated within the expected time interval. 

The data page displays the list of vehicles based on details such as Make and Model.

As an application developer, you need to unit test the developed features:

  1.  Create Pega unit tests for the data page with different values for the Make list.
  2.  Run the created unit tests.
  3.  Open any failed test case, and then identify the reason for failure.

The following table provides the credentials you need to complete the challenge.

Role User name Password
Application Developer pgpTester rules123!
Note: Your practice environment may support the completion of multiple challenges. As a result, the configuration shown in the challenge walkthrough may not match your environment exactly.

You must initiate your own Pega instance to complete this Challenge.

Initialization may take up to 5 minutes so please be patient.
