Below is the code that I wrote with mocha, chai and supertest. I have a question with regards to the segment of code below that works, with focus on token.
describe('Authenticated userTest', function () {
var token;
before(function loginAuth(done) {
request(app)
.post("/login/local")
.send("username=testName")
.send("password=qwe123QWE")
.expect(function (res) {
should.exist(res.body.token);
token = res.body.token;
})
.end(done);
});
it('should give me a defined token', function(done) {
console.log("token is " + token);
done();
});
});
Apparently, token is defined all well and good here. However, when I remove the done function as follows:
describe('Authenticated userTest', function () {
var token;
before(function loginAuth() { //done is removed here
request(app)
.post("/login/local")
.send("username=testName")
.send("password=qwe123QWE")
.expect(function (res) {
should.exist(res.body.token);
token = res.body.token;
})
.end(); //done is removed here
});
it('should give me a defined token', function(done) {
console.log("token is " + token);
done();
});
});
Token becomes undefined. From what I understand, done is a function passed down from the before hook to all the various tests thereafter that starts with it(...) from the inbuilt source code.
Thus, I want to clarify that particular question (if done is passed only across the tests; if done only accepts the err parameter) and why did the token become undefined after removing the done parameter?
Thank you.
