Your call to and_return(500, 100) is being set on each new
OtherFooClassinstance. It is
*not* a stub shared by all instances. So in your example, each new instance
of OtherFooClass will return 500 the first time you call other_foo and then
100 on all subsequent calls.
My 2cents: do not use allow_any_instance_of. Instead setup explicit doubles
for each new instance. Something like:
foo1 = double(OtherFooClass, other_foo: 500)
foo2 = double(OtherFooClass, other_foo: 100)
allow(OtherFooClass).to receive(:new).and_return(foo1, foo2)
*IF* you really must use any_instance you'll need to keep track of the
return values. By manipulating the block form of and_return along with a
closure you can achieve this with:
return_values = [500, 100]
allow_any_instance_of(OtherFooClass).to receive(:other_foo).and_return{
return_values.shift
}
For completeness, receive could also be passed the block to achieve the
same result.
