Sinon: How do we verify stub called with argument that is an array

Created on 17 Dec 2015 · 4Comments · Source: sinonjs/sinon

argument = ["1","2","3"] to a sinon stub.
I wish to check the argument and return value. I am unable to do the same using

stub.withArgs(argument).return(value); // its unable to match
stub.withArgs(sinon.match.array).return(value); // able to match
stub.withArgs(sinon.match.array.and(sinon.match.has("length", 3) // able to match

I am able to debug using WebStorm and verify that argument is passed to the stub.

Please help.

For anyone looking, here is the answer by @mroderick himself.

var expectedValue = [1, 2, 3];
var myStub = sinon.stub;

// let's pretend this is the call you want to verify
myStub(expectedValue);

var firstArgument = myStub.getCall(0).args[0];
assert.equal(firstArgument, expectedValue);

Or stubName.getCall(0).thisValue.$$paramName;
