As you know, by default, test methods don’t support web service callouts, and tests that perform web service callouts fail. Apex provides the built-in WebServiceMock interface and the Test.setMock method to prevent tests from failing. So, today, we are back with yet another Salesforce solution. Let’s know how to create a mock callout to test the Apex rest callout in Salesforce.

Further, the Apex test class will not let us conduct an HTTP callout. Hence, you cannot test external APIs. But, Apex does have an interface called HttpCalloutMock for standard callout tests.

Let’s get started!
