The following example tests the Cloud Code method from the dependency injection guide. This example uses two separate mock instances of . The first instance is injected through the class constructor, and the other instance is passed directly to the method. This example verifies that both injection points work correctly. The two instances use different values ( and ) so that you can identify which injection point failed if the assertion doesn't pass.

Run the unit test according to your IDE and confirm that the test passes.
