We need to provide implementation for all methods and delegate. We can make use of lombok @Delegate annotation for this - https://www.initialyze.com/blog/2020/11/simplify-extending-sling-models-with-lombok/ Also, note that your custom interface(PageExporter) has methods in the same name as OOTB core...

@siva_k222,OSGi config values created as Map object is the way we mock OSGi config in the Test class.
