Sinon.JS has a few utilities used internally in lib/sinon.js
. Unless the method in question is documented here, it should not be considered part of the public API, and thus is subject to change.
sinon.createStubInstance(constructor);
Creates a new object with the given function as the protoype and stubs all implemented functions.
class Container { contains(item) { /* ... */ } } var stubContainer = sinon.createStubInstance(Container); stubContainer.contains.returns(false); stubContainer.contains.withArgs("item").returns(true);
The given constructor function is not invoked. See also the stub API.
