How to increase timeout for a single test case in mocha

Question

I\'m submitting a network request in a test case, but this sometimes takes longer than 2 seconds (the default timeout).

How do I increase the timeout for a single te

Answer 1

This worked for me! Couldn't find anything to make it work with before()

describe("When in a long running test", () => {
  it("Should not time out with 2000ms", async () => {
    let service = new SomeService();
    let result = await service.callToLongRunningProcess();
    expect(result).to.be.true;
  }).timeout(10000); // Custom Timeout 
});

For test navegation on Express:

const request = require('supertest');
const server = require('../bin/www');

describe('navegation', () => {
    it('login page', function(done) {
        this.timeout(4000);
        const timeOut = setTimeout(done, 3500);

        request(server)
            .get('/login')
            .expect(200)
            .then(res => {
                res.text.should.include('Login');
                clearTimeout(timeOut);
                done();
            })
            .catch(err => {
                console.log(this.test.fullTitle(), err);
                clearTimeout(timeOut);
                done(err);
            });
    });
});

In the example the test time is 4000 (4s).

Note: setTimeout(done, 3500) is minor for than done is called within the time of the test but clearTimeout(timeOut) it avoid than used all these time.
