I am learning about Protractor (and, by extension, Jasmine, that Protractor uses) and I need, for a certain reason, need to wait for a Promise to continue testing. However, I am not sure how to do that.
Let's take the code from Protractor tutorial and add some code, and let's add a simple Promise (in ES6 style) that doesn't do anything
describe('angularjs homepage todo list', function() {
it('should add a todo', function() {
browser.get('https://angularjs.org');
element(by.model('todoList.todoText')).sendKeys('write first protractor test');
element(by.css('[value="add"]')).click();
var todoList = element.all(by.repeater('todo in todoList.todos'));
Promise.resolve().then( () => {
expect(todoList.count()).toEqual(3);
expect(todoList.get(2).getText()).toEqual('write first protractor test');
// You wrote your first test, cross it off the list
todoList.get(2).element(by.css('input')).click();
var completedAmount = element.all(by.css('.done-true'));
expect(completedAmount.count()).toEqual(2);
});
});
});
This doesn't work, because this is the answer
$ protractor conf.js
Using the selenium server at http://localhost:4444/wd/hub
[launcher] Running 1 instances of WebDriver
F
Failures:
1) angularjs homepage todo list should add a todo
Message:
Error while waiting for Protractor to sync with the page: "angular could not be found on the window"
Stacktrace:

[launcher] 0 instance(s) of WebDriver still running
[launcher] chrome #1 failed 1 test(s)
[launcher] overall: 1 failed spec(s)
[launcher] Process exited with error code 1
What should I do to make it work?
I solved it in a following way:
framework: 'jasmine2'
to conf.js
Editing the file like this
var flow = browser.flow() describe('angularjs homepage todo list', function() { it('should add a todo', function() { browser.get('https://angularjs.org'); element(by.model('todoList.todoText')).sendKeys('write first protractor test'); element(by.css('[value="add"]')).click(); var todoList = element.all(by.repeater('todo in todoList.todos')); flow.execute(function(){Promise.resolve()}); // or, more ES6-y version // flow.execute(() => Promise.resolve()); expect(todoList.count()).toEqual(3); expect(todoList.get(2).getText()).toEqual('write first protractor test'); // You wrote your first test, cross it off the list todoList.get(2).element(by.css('input')).click(); var completedAmount = element.all(by.css('.done-true')); expect(completedAmount.count()).toEqual(2); }); });
Jasmine is actually "chaining" the promises in expect together itself, which conveniently solves my problem.
