So, with all this in mind I created a helper class in the form of the UnitTestUtil class. The only way to… So they protect the situation by banning such code right away ;) I recently wrote about a technique for using a singleton pattern to create a unit test class that could pass mock callout responses titled A Better Way to Unit Test Callouts in Apex Code.

Update: In this article I describe using a singleton class to set a property that can be checked by web service methods to check if the call is being executed as part of a unit test as well as what mock response to return. The integrations usually go pretty smoothly but one part that has always seemed to be a pain is unit testing. Different ways of testing HTTP callout in apex As we all know that test methods do not support HTTP callout, so all test method performing callout will fail.

The Intro to Apex Code Test Methods has one solution to testing as much of an HTTP callout as possible. Apex methods in your apex code can be exposed as web services so that these services can be consumed by any REST client. on to.
