In this recipe, we will perform the verification of the interaction with a mock, but at the same time, we will ignore the stubbed methods from this verification.
For this recipe, our system under test will be a TaxTransferer class that will transfer tax through the web service for the given person if this person is not null. It will send a statistics report regardless of the fact whether the transfer took place or not:
public class TaxTransferer {
private final TaxService taxService;
public TaxTransferer(TaxService taxService) {
this.taxService = taxService;
}
public boolean transferTaxFor(Person person) {
if(person != null) {
taxService.transferTaxFor(person);
}
return taxService.sendStatisticsReport();
}
}
