AD0-E103 Sample Questions Answers

A developer is working on the following Sling Model that is being used in a component.

@Model(adaptables = SlingHttpServletRequest.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)

public class SampleModel {

@Inject

private Page currentPage;

private boolead matchingTitle;

@PostConstruct

private void init(){

matchingTitle = title.equals(currentPage.getName());

}

public boolean isMatchingTitle(){

return matchingTitle;

}

}

The model must check if the configured value of the jct:title property for the component matches the same name of the current page. If the jcr:title property of the component has NOT been configured, then isMatchingTitle() must return false.

How should the developer inject the title property in this model?

The following three service interfaces are used:

MortgageCalculationServlet, MortgageCalculationService and ObjectValueLookupRestService where MortgageCalculationServlet has a dependency to MortgageCalculationService and MortgageCalculationService has a dependency to ObjectValueLookupRestService.

The calculation has many combinations of input parameters and edge cases, so the JUnit coverage must be as high as possible.
