F.I.R.S.T. Principles of Tests Suites

THIS IS ALL ABOUT TESTING

  • Big Team

  • Many Projects

  • Many Test Suites

F.I.R.S.T.

  • Fast
  • Isolated
  • Repeatable
  • Self-verifying
  • Timely

FAST

it('throws an error on wrong query', function (done) {

    stub = sinon
        .stub(analyticsService, '_queryAPI')
        .returns(BPromise.reject(
            new Error('Something went wrong')
        ));

    analyticsService.queryAPI({})
        .catch(Error, function (err) {

            expect(err.message)
                .to.equal('Something went wrong');

            done();
        });

});

ISOLATED

it('Should handle recommended video filtering', function (done) {

    var request = shopPagesService
        .prepareRequest({'videos.recommended': 'VIDEOID'}, {});

    expect(request.query)
        .to.have.property('videos.recommended.video')
        .and.to.equals('VIDEOID');
    expect(request.query)
        .to.not.have.property('videos.recommended');

    done();

});
describe('Handle recommended video filtering', function (done) {

    var request = {};

    before(function (done) {

        request = shopPagesService
                    .prepareRequest({'videos.recommended': 'VIDEOID'}, {});
    });

    it('Should contain recommended videos property', function (done) {
        
        expect(request.query)
            .to.not.have.property('videos.recommended');    
        done();
    });

    it('Should contain the ID', function (done) {
        
        expect(request.query)
            .to.have.property('videos.recommended.video')
            .and.to.equals('VIDEOID');
        done();
    });
});

REPEATABLE

describe('Sorting', function () {

    before(function (done) {

        /*
         * Create a couple of platforms
         */
    });

    it('Sorts results on name with default order', function (done) {

        /*
         * Test since you know the state of the DB
         */
    });

    after(function (done) {

        /*
         * Delete the previous created platforms 
         * so we leave the DB in the previous state
         */
    });
});

SELF-VERYFYING

Tests should always assert something.

TIMELY
