Nightwatch.js custom command this vs this.api - nightwatch.js

// myCustomCommand.js
module.exports = function () {
this.SOME_NIGHTWATCH_COMMAND(...) // fails, undefined
this.api.SOME_NIGHTWATCH_COMMAND(...) // works
}
Anybody know what's going on?

module.exports.command = ... instead of module.exports = ...

Spying on puppeteer calls

I'm building a web scraper that uses puppeteer. I'd obviously like to ensure that I don't break things as I work the kinks out and so I'm writing some implementation tests.
How would I go about testing out the code below? The issue is that newPage() is nested and I can't figure out how to create a spy for it.
Any ideas? Should I structure the code differently to make it easier to test (from what I've read this a big no-no). Happy to hear your suggestions.
//myFile
myFn(){
let browser = puppeteer.launch()
let page = browser.newPage();
}
describe('searchAddress', () => {
beforeEach(() => {
browserSpy = spyOn(puppeteer,'launch')
pageSpy = spyOn(puppeteer,'newPage') // <--- ????
})
it('should ensure the calls were made', async () => {
await myFn()
expect(sleepSpy).toHaveBeenCalled();
expect(pageSpy).toHaveBeenCalled();
});
});
In this case the spyOn(puppeteer,'launch') should return an object that contains a spy object for newPage call. I mean the followings:
describe('searchAddress', () => {
let newPageSpy;
let browserSpy;
beforeEach(() => {
// ARRANGE
newPageSpy = jasmine.createSpy();
let browserMock = { newPage: newPageSpy };
browserSpy = spyOn(puppeteer, 'launch').and.returnValue(browserMock);
});
it('should ensure the calls were made', async () => {
// ACT
await myFn();
// ASSERT
expect(newPageSpy).toHaveBeenCalled();
});
});

How to cover all lines of a function with jasmine-karma

How can I cover all lines of the function below using jasmine?
addUser(): void {
if (this.validateNewUser()) {
this.newUser._Job = this.selectedJob;
this.newUser.PositionId = this.selectedJob.Id;
this.newUser.Position = this.selectedJob.Value;
this.newUser._Area = this.selectedArea;
this.newUser.AreaId = this.selectedArea.Id;
this.newUser.Area = this.selectedArea.Value;
this.users.push(this.newUser);
this.clear();
this.toastService.open('Usuário incluído com sucesso!', { type: 'success', close: true });
}
}
I am currently trying as follows, but no line is being considered covered:
it('Given_addUser_When_UserStepIsCalled_Then_ExpectToBeCalled', (done) => {
component.addUser = jasmine.createSpy();
component.addUser();
expect(component.addUser).toHaveBeenCalled();
done();
});
EDITED
Now:
Image here
There is no need to check if the method under test (addUser) has been called if you explicitly call it. You should however check if the method did what it was supposed to do. You may want to know if the toast gets displayed. Therefore, you could rewrite the test as follows.
it('#addUser should display toast', () => {
// given
spyOn(toastService, 'open');
// when
component.addUser();
// then
expect(toastService.open).toHaveBeenCalled();
});

Async call in beforeAll

Here are 2 samples of the same test. The only difference is that first one uses a promise in beforeAll block to assign a value to the variable while the second one assigns the value directly.
I raised a similar question Running spec after promise has been resolved with one of the comments pointing to this issue https://github.com/jasmine/jasmine/issues/412 which says that this is not supported in Jasmine. Has somebody figured out any workaround?
This fails with TypeError: Cannot read property 'forEach' of undefined
describe('Async car test', function () {
var cars;
beforeAll(function (done) {
// getCars() is a promise which resolves to ['audi', 'bmw']
getCars().then(function (data) {
cars = data;
console.log(cars) // ['audi', 'bmw']
done();
});
});
cars.forEach(function (car) {
it('car ' + car, function () {
expect(car).toBe(car);
});
});
});
This works fine
describe('Car test', function () {
var cars = ['audi', 'bmw'];
cars.forEach(function (car) {
it('car ' + car, function () {
expect(car).toBe(car);
});
});
});
Posting it as an answer, because I can't see things properly in comments.
I'm actually generating tests in my spec as well, and I'm using https://www.npmjs.com/package/jasmine-data-provider , I think you probably cannot generate it directly from resolved promise. And wrapping in another it doesn't work for you. This should work:
var using = require('jasmine-data-provider');
using(cars.forEach, function (car) {
it(car + ' should be' + car, function () {
expect(car).toBe(car);
});
});
This is not an issue with jasmine, it is an issue with your code.
beforeAll does not block subsequent code below the statement. it blocks code that is defined in it('should ...', (done)=>{...});
it('should have cars', (done) => {
cars.forEach(function (car) {
expect(car).toBe(car);
});
});
Since Jasmine does not support adding tests at runtime, the trick is to request the asynchronous data before starting Jasmine, and then using the retrieved data during runtime instead. This can be achieved with a singleton and programmatically starting Jasmine.
See here for a working example.
// car-collection.js
class CarCollection {
static load() {
return this.request()
then((data) => this.cars = data);
}
static request() {
// in practice this function would do something cooler
return Promise.resolve(['audi', 'bmw']);
}
}
modules.export = CarCollection;
Since CarCollection has methods that are static they will be shared across imports and this.cars will persist.
// launcher.js
const Jasmine = require('jasmine');
const CarCollection = require('./car-collection');
CarCollection.load()
.then(() => {
console.log(`car count is ${CarCollection.cars.length}`); // prints: car count is 2
const jasmine = new Jasmine();
jasmine.loadConfigFile(...); // path to jasmine.json
jasmine.execute();
});
An important step here is configure jasmine to know where to look for the test files. Either by loading a config or passing specifics into the execute function.
// car.spec.js
const CarCollection = require('./car-collection');
describe('test', function () {
CarCollection.cars.forEach((car) => {
it('test' + car, () => {
expect(car).toBe(car);
});
});
});
Now run node ./launcher.js and the tests should run.

Combining koa-router with koa-handlebar

I am trying to use koa-handlebars (a server-side templating engine) with koa-routers in koa.
.get('/', function* () {
this.body = this.render('myViewHere', {});
})
There is no documentation on this!
The only documentation is this:
app.use(function* () {
yield this.render('myViewHere', {});
});
I had to use the middleware on the router for it to work.
// more code above...
var handlebars = require("koa-handlebars");
var router = require('koa-router');
var myRouter = new router();
myRouter.use(handlebars({
defaultLayout: 'main'
}));
myRouter.get('/', function* () {
yield this.render('myView', {});
})
// more code below...
Actually I suggest you to use koa-ejs with koa. it's relatively supported module, which easy to use.
You can use koa-hbs, but you will encounter issues when using it with partials.

Jasmine2: get current spec name

In Jasmine 1.3, we had this option to the get current spec and suite names:
describe("name for describe", function () {
it("name for it", function () {
console.log(this.suite.getFullName()); // would print "name for describe"
console.log(this.description); // would print "name for it"
});
});
This does not longer work in Jasmine 2.x.
Anyone knows how to fetch those?
Thanks.
I add a new jasmine reporter, then get the spec name without define N variable on each spec. Hope can help, thanks.
var reporterCurrentSpec = {
specStarted: function(result) {
this.name = result.fullName;
}
};
jasmine.getEnv().addReporter(reporterCurrentSpec);
The reason this no longer works is because this is not the test. You can introduce a subtle change to your declarations however that fix it. Instead of just doing:
it("name for it", function() {});
Define the it as a variable:
var spec = it("name for it", function() {
console.log(spec.description); // prints "name for it"
});
This requires no plug-ins and works with standard Jasmine.
As far as Jasmine 2 is concerned currentSpec is discontinued on purpose. However there is a custom plugin/library developed that is based on jasmine reporter plugin which you can use. Here's the Link. Hope it helps with your requirement.
Its very simple to use, install the package with npm command -
npm install -g jasmine-test-container-support
Get the test container support by writing below lines before your describe or test suite -
var JasmineTestContainerSupport = window.JasmineTestContainerSupport || require('jasmine-test-container-support');
JasmineTestContainerSupport.extend(jasmine);
Later use the test container in your spec's to get its description -
var specDesc = jasmine.getEnv().getTestContainer();
Hope this helps.
var currentSpecName = describe('Test1', function() {
var currentStepName = it("Step1", function(){
console.log(currentStepName.description); // Prints It Name
console.log(currentSpecName.getFullName()); //Prints Describe Name
});
});
This worked for me in jasmine 3.5+
I know this is a relatively old question but found something which worked for me
describe('Desc1',() => {
afterEach(() => {
const myReporter = {
specDone: (result) => {
console.log('Spec FullName: ' + result.fullName);
console.log('Spec Result: ' + result.status);
}
};
jasmine.getEnv().addReporter(myReporter);
});
})

This is probably a bit late but you can get the suite name outside the spec.
Please try the following code:
describe("name for describe", function () {
console.log(this.getFullName()); // would print "name for describe"
it("name for it", function () {
//Your test spec
});
});
