Define helper chain function

I often perform chai requests with authorization:

chai.request(baseUrl).get(`/resource`).set('authorization', `Bearer ${token}`)

I would like to factorize the autorization in a function called withAuth, so I can reuse it more conveniently:

chai.request(baseUrl).get(`/resource`).withAuth()

But I'm not sure how to do that? I tried:

let withAuth = () => {set('authorization', `Bearer ${token}`)}

But this doesn't work.

Solution

  • Use addChainableMethod of Assertion prototype :

    chai.Assertion.addChainableMethod('withAuth',(request) => request.set('authorization', `Bearer ${token}`));

    You can refer to this documentation and have a look on the utility method addChainableMethod
