public class SampleModel {
@Inject
private Page currentPage; private boolead matchingTitle;

NEW QUESTION 12
A banking AEM application contains functionality to calculate a mortgage rate based on user input. A servlet in place calculates the result in the backend. A call to an internal third-party REST service is required to retrieve the average object value based on a given zip code.
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.
Which two strategies should the developer use to ensure testability of the application code? (Choose two)

• A. Use the standard OSGi @Reference annotation to wire the dependencies in application code
• B. Use BundleContext.getServiceReference(...) and BundleContext.getService(...) in application code to look up for the required services just before usage
• C. Deploy a third party dependency injection container to wire dependencies more efficiently in application code
• D. Use a mock framework to be able to create and inject mocks in the test code

• C. Create a folder named "deploy" under $AEM_HOME/crx-quickstart/ and copy com.example.customlib-3.8.jar in there so AEM uploads it automatically
• D. Go to the project parent pom.xml file and add the dependency with the scope "compile" and instruct the bundle plugin to include the dependency in runtime
• E. Upload the file com.example.customlib-3.8.jar into /apps/<project>/libs folder in CRX DE to make it available for the OSGi bundle
