How to mock a web service callout in apex?
To mock a callout if the code that performs the callout is in a managed package, call Test.setMock from a test method in the same package with the same namespace. This example shows how to test a web service callout. The implementation of the WebServiceMock interface is listed first.
How to create mock class for multiple callouts in single class?
This need is covered in Testing Apex Callouts using HttpCalloutMock. Specifically, see the Testing multiple HTTP callouts section. Here’s the example they use: I’m not sure why they don’t annotate the class as @IsTest. You probably should. I’ve created a generic “utility” class that makes this much easier to do (and all HTTP testing in general).
How to test multiple callouts using httpcalloutmock?
Like our SingleRequestMock utility, the class above also implements the HttpCalloutMock interface. However, unlike SingleRequestMock, this class is simply a wrapper that maintains a Map of HTTP endpoints –> their dummy HttpCalloutMock implementations. Lets see how we can use this utility class to test our multiple callout code.
What does respond do in multirequestmock class?

How to test the callout mode in websvccallout?

Which is an example of webservicemock interface?
The implementation of the WebServiceMock interface is listed first. This example implements the doInvoke method, which returns the response you specify. In this case, the response element of the auto-generated class is created and assigned a value. Next, the response Map parameter is populated with this fake response.
