HTTP Mock Registry - A Simplified Way to Mock Apex Callouts
Apex leaves much to be desired when it comes to mocking callouts to external services. Use of the HttpCalloutMock interface requires that a test author configure mock responses for ALL callouts made through the course of a test’s processing, and this can be quite unmanageable in large or complex projects. There must be a better way… Enter the HTTP Mock Registry.
Frustrated with messy tests and abstraction leaks, we’ve devised a utility that provides a intuitive interface for mocking callouts declaratively as well as a foundation for more modular test suites whenever callouts are involved.
