MultipleHAMTests - Create tests for Multiple HAMs with qualifiers

[TheoGkoumas]

• Simple testing strategy as need to test the most likely and applicable scenarios.
• Create Custom HAM Handler and ensure it is favoured over the in-built one (this is core to testing HAMs with qualifiers as the Jakarta specification states that if at least one HAM is defined with a qualifier, then a Custom HAM handler must be present!).
• SCENARIO 1: Testing 3 BasicHAMs (two with qualifiers, one without), and a Form HAM (with qualifier) and a CustomForm HAM (with qualifier) - and then, in the Custom HAM handler, ensuring all the HAMs are injected. NOTE: 4 qualifiers in total - Admin, User, Operator and Tester.
• SCENARIO 2: Testing 1 BasicHAM (without a qualifier) - and then, in the Custom HAM handler, ensuring it is injected using the @default annotation, and the same one can be selected without an annotation.
• SCENARIO 3: Testing 2 BasicHAMs (both with qualifiers) - and then, in the Custom HAM handler, ensuring the two HAMs are injected in with their qualifiers, and also one of them can be injected with the @default annotation and the same one can be selected without an annotation.
• Testing log file output to ensure a clear info message showing which HAMHandler was selected (it will be the name of the Custom HAM handler in the application).
• Testing log file output to make sure no unexpected error messages are output.
• Negative testing:
  • conditions for raising Exception (including log file message) - this is done by having at least one HAM defined with a qualifier, but not having a Custom HAM Handler within the application.

Test class name: MultipleHAMTests

Implementation

• For in-built HAMs, @Form.., @CustomForm... and @basic... would be sufficient.
• Also, define - in four separate Java classes - four annotations: Admin, User, Operator and Tester. Admin is shown below.
• Lastly, use a user registry for credentials.

@Qualifier
@Retention(RUNTIME)
@Target({TYPE, METHOD, FIELD, PARAMETER})
public @interface Admin {
}
