Does anyone have any idea how you would handle errors in gulp-ruby-sass. I have noticed that it outputs directly to console when there is an error, but I would like to handle it myself.
gulp.task('styles', function () {
return gulp.src(sources.sass.files)
.pipe(plumber({errorHandler: notify.onError("Error: <%= error.message %>")}))
.pipe(
plugins.rubySass({
lineNumbers: true,
style: 'expanded',
sourcemap: true,
sourcemapPath: '../../dev/sass'
})
)
.on("error", function(err) {
console.log(err);
})
.pipe(gulp.dest(sources.sass.dest));
});
As you can see, I am trying two different ways to handle my error here but neither of them work. If I try .on("error", console.log('error')) that works, but it tells me the 'listener must be a function'.
Thanks in advance.
You can also use a package I published, pipe-error-stop as follows:
pipeErrorStop = require('pipe-error-stop');
// in the task
.pipe(pipeErrorStop(rubySass()))
If rubySass emits an error, no data will be passed onward further down the pipe. This prevents you from making a syntax error in your sass and finding a stack trace on your home page.
pipeErrorStop has callbacks that you can use to hook into, as well.
Using gulp-plumber might help you, have a look at this blogpost !
It would allow you do:
var onError = function (err) {
// whatever you need to do
};
gulp.task('styles', function () {
gulp.src('scss/style.scss')
.pipe(plumber({
errorHandler: onError
}))
.pipe(rubysass())
.pipe(gulp.dest('dist/'));
});

This question is not about a problem which I can't solve, it is just a curiosity. I'm not very experienced with Mocha, but there's something interesting I've stumbled upon already.
What I want is to use done() to tell Mocha the promise has been resolved.
The following code DOESN'T work:
beforeEach((done) => {
user = new User({ name: 'Dummy' })
user.save()
.then(done)
})
I know I'm passing the result of the user.save() promise to done, but I think it shouldn't be a problem.
Instead this other code works:
beforeEach((done) => {
user = new User({ name: 'Dummy' })
user.save()
.then(() => done())
})
It seems to me that Mocha done() has some kind of control flow which leads to: Error: done() invoked with non-Error: {"_id":"5b65b9d2669f7b2ec0a3d503","name":"Dummy","__v":0}
Is it because done() wants strictly an error as its argument?
Why done() does even care about what I pass to it?
Can you make some example showing why done() argument to be an Error is useful?
Thanks in advance ;)
It is because done() in Mocha only accepts Error argument. In your case, your save() method returns json object not an Error ie new Error('failed save').
If we take a look at mocha test file, we can see that it won't accept other type of arguments.
// https://github.com/mochajs/mocha/blob/master/test/unit/runnable.spec.js#L358
describe('when done() is invoked with a string', function () {
it('should invoke the callback', function (done) {
var test = new Runnable('foo', function (done) {
done('Test error'); // specify done with string/text argument
});
test.run(function (err) {
assert(err.message === 'done() invoked with non-Error: Test error');
done();
});
});
});
But if we see the test when the argument is Error, it works
// https://github.com/mochajs/mocha/blob/master/test/unit/runnable.spec.js#L345
describe('when an error is passed', function () {
it('should invoke the callback', function (done) {
var test = new Runnable('foo', function (done) {
done(new Error('fail'));
});
test.run(function (err) {
assert(err.message === 'fail');
done();
});
});
});
Btw, I suggest that you avoid using done since mocha supports promise by specifying return statement. So, we change the code into
beforeEach(() => {
user = new User({ name: 'Dummy' })
return user.save().then(user => {
// antyhing todo with user
});
});
Hope it helps.
I have recently installed the jasmine-spec-reporter package in order to produce more verbose and helpful logging during execution of test suites.
I want to be able to log expected and actual values for failed test cases and was wondering if I needed to explicitly have a statement in the form of expect(someCondition).toEqual(true); in order for me to see these values.
For example, I have a function like the following:
it('should log in', function(done) {
var customerNameElement;
customerNameElement = element.all(by.xpath('some_xpath')).first();
core.infoMessage(browser, JSON.stringify(params, undefined, 4));
login.login(browser, undefined, undefined, getWaitTime())
.then(function() {
return browser.wait(protractor.ExpectedConditions.and(
function() { return core.isUnobscured(browser, customerNameElement);
}, protractor.ExpectedConditions.elementToBeClickable(customerNameElement)), getWaitTime());
})
.catch(fail)
.then(done);
});
I can still log the failure to the console but not in the form that I'd like. Does jasmine-spec-reporter handle this or do I have to add the statement from above in each test case?
Also, does the fail keyword in the .catch() have any properties I can use to my advantage? It comes from:
// Type definitions for Jasmine 2.5.2 // Project: http://jasmine.github.io/
Thanks
you can try adding the below in protractor_config file:
let SpecReporter = require('jasmine-spec-reporter').SpecReporter;
exports.config = {
// your config here ...
onPrepare: function () {
jasmine.getEnv().addReporter(new SpecReporter({
spec: {
displayStacktrace: true
}
}));
}
}
Also, add the print function in the jasmineNodeOptssection
jasmineNodeOpts: {
...
print: function() {}
}
I heard that the webdriver Control flow is being removed in the future, and wanted to update my test cases.
I am not sure what is the better way to replace it:
Async await: worked well, but are not supported by jshint.
promises chaining: I don't know how to ensure promises chaining with jasmin.
For example:
it('should should clear qa cookies using the qa command', function() {
browser.waitForAngularEnabled(false)
.then(browser.get('cookies url'));
});
it('should open product page', function() {
browser.waitForAngularEnabled(true)
.then(browser.get('page-url'))
.then(browser.wait(function() {
return element.all(by.css('locator')).first().isDisplayed();
}))
.then(expect(true).toBe(true));
});
How to make the second spec to be run only after the first spec ??
Thank you !!!
I still recommend to use async/await. Problems will happen when you will need to work with pageobjects, save some data for future use and so on.
If your jshint is erroring, consider TypeScript + TSlint
You need 'return' and for clean view- arrow functions
it('should should clear qa cookies using the qa command', function() {
return browser.waitForAngularEnabled(false)
.then(() => browser.get('cookies url'));
});
it('should open product page', function() {
return browser.waitForAngularEnabled(true)
.then(() =>browser.get('page-url'))
.then(() =>browser.wait(() => element.all(by.css('locator')).first().isDisplayed()))
.then(() => expect(true).toBe(true));
});
describe('my homepage', function() {
var ptor = protractor.getInstance();
beforeEach(function(){
// ptor.ignoreSynchronization = true;
ptor.get('http://localhost/myApp/home.html');
// ptor.sleep(5000);
})
describe('login', function(){
var email = element.all(protractor.By.id('email'))
, pass = ptor.findElement(protractor.By.id('password'))
, loginBtn = ptor.findElement(protractor.By.css('#login button'))
;
it('should input and login', function(){
// email.then(function(obj){
// console.log('email', obj)
// })
email.sendKeys('josephine#hotmail.com');
pass.sendKeys('shakalakabam');
loginBtn.click();
})
})
});
the above code returns
Error: Error while waiting for Protractor to sync with the page: {}
and I have no idea why this is, ptor load the page correctly, it seem to be the selection of the elements that fails.
TO SSHMSH:
Thanks, your almost right, and gave me the right philosophy, so the key is to ptor.sleep(3000) to have each page wait til ptor is in sync with the project.
I got the same error message (Angular 1.2.13). My tests were kicked off too early and Protractor didn't seem to wait for Angular to load.
It appeared that I had misconfigured the protractor config file. When the ng-app directive is not defined on the BODY-element, but on a descendant, you have to adjust the rootElement property in your protractor config file to the selector that defines your angular root element, for example:
// protractor-conf.js
rootElement: '.my-app',
when your HTML is:
<div ng-app="myApp" class="my-app">
I'm using ChromeDriver and the above error usually occurs for the first test. I've managed to get around it like this:
ptor.ignoreSynchronization = true;
ptor.get(targetUrl);
ptor.wait(
function() {
return ptor.driver.getCurrentUrl().then(
function(url) {
return targetUrl == url;
});
}, 2000, 'It\'s taking too long to load ' + targetUrl + '!'
);
Essentially you are waiting for the current URL of the browser to become what you've asked for and allow 2s for this to happen.
You probably want to switch the ignoreSynchronization = false afterwards, possibly wrapping it in a ptor.wait(...). Just wondering, would uncommenting the ptor.sleep(5000); not help?
EDIT:
After some experience with Promise/Deferred I've realised the correct way of doing this would be:
loginBtn.click().then(function () {
ptor.getCurrentUrl(targetUrl).then(function (newURL){
expect(newURL).toBe(whatItShouldBe);
});
});
Please note that if you are changing the URL (that is, moving away from the current AngularJS activated page to another, implying the AngularJS library needs to reload and init) than, at least in my experience, there's no way of avoiding the ptor.sleep(...) call. The above will only work if you are staying on the same Angular page, but changing the part of URL after the hashtag.
In my case, I encountered the error with the following code:
describe("application", function() {
it("should set the title", function() {
browser.getTitle().then(function(title) {
expect(title).toEqual("Welcome");
});
});
});
Fixed it by doing this:
describe("application", function() {
it("should set the title", function() {
browser.get("#/home").then(function() {
return browser.getTitle();
}).then(function(title) {
expect(title).toEqual("Welcome");
});
});
});
In other words, I was forgetting to navigate to the page I wanted to test, so Protractor was having trouble finding Angular. D'oh!
The rootElement param of the exports.config object defined in your protractor configuration file must match the element containing your ng-app directive. This doesn't have to be uniquely identifying the element -- 'div' suffices if the directive is in a div, as in my case.
From referenceConf.js:
// Selector for the element housing the angular app - this defaults to
// body, but is necessary if ng-app is on a descendant of <body>
rootElement: 'div',
I got started with Protractor by watching the otherwise excellent egghead.io lecture, where he uses a condensed exports.config. Since rootElement defaults to body, there is no hint as to what is wrong with your configuration if you don't start with a copy of the provided reference configuration, and even then the
Error while waiting for Protractor to sync with the page: {}
message doesn't give much of a clue.
I had to switch from doing this:
describe('navigation', function(){
browser.get('');
var navbar = element(by.css('#nav'));
it('should have a link to home in the navbar', function(){
//validate
});
it('should have a link to search in the navbar', function(){
//validate
});
});
to doing this:
describe('navigation', function(){
beforeEach(function(){
browser.get('');
});
var navbar = element(by.css('#nav'));
it('should have a link to home in the navbar', function(){
//validate
});
it('should have a link to search in the navbar', function(){
//validate
});
});
the key diff being:
beforeEach(function(){
browser.get('');
});
hope this may help someone.
I was getting this error:
Failed: Error while waiting for Protractor to sync with the page: "window.angular is undefined. This could be either because this is a non-angular page or because your test involves client-side navigation, which can interfere with Protractor's bootstrapping. See http://git.io/v4gXM for details"
The solution was to call page.navigateTo() before page.getTitle().
Before:
import { AppPage } from './app.po';
describe('App', () => {
let page: AppPage;
beforeEach(() => {
page = new AppPage();
});
it('should have the correct title', () => {
expect(page.getTitle()).toEqual('...');
})
});
After:
import { AppPage } from './app.po';
describe('App', () => {
let page: AppPage;
beforeEach(() => {
page = new AppPage();
page.navigateTo();
});
it('should have the correct title', () => {
expect(page.getTitle()).toEqual('...');
})
});
If you are using
browser.restart()
in your spec some times, it throws the same error.
Try to use
await browser.restart()
I have a bunch of failing specs from a rather large architectural change. I'd like to work on fixing them one by one by tagging each one with 'focus'.
Does jasmine.js have a feature like this? I swore I read at one point that it does but I don't see it in the docs.
When using Karma, you can enable only one test with fit or fdescribe (iit and ddescribe in Jasmine before 2.1).
This only runs Spec1:
// or "ddescribe" in Jasmine prior 2.1
fdescribe('Spec1', function () {
it('should do something', function () {
// ...
});
});
describe('Spec2', function () {
it('should do something', function () {
// ...
});
});
This only runs testA:
describe('Spec1', function () {
// or "iit" in Jasmine prior 2.1
fit('testA', function () {
// ...
});
it('testB', function () {
// ...
});
});
In core since 2.1 with fit and fdescribe.
You can run a single spec by using the url for the spec
describe("MySpec", function() {
it('function 1', function() {
//...
})
it('function 2', function() {
//...
}
})
Now you can run just the whole spec by this url http://localhost:8888?spec=MySpec and a the first test with http://localhost:8888?spec=MySpec+function+1
There are a few ways you can do it.
There is: Jasmine's feature Focused Specs (2.2): http://jasmine.github.io/2.2/focused_specs.html
Focusing specs will make it so that they are the only specs that run. Any spec declared with fit is focused.
describe("Focused specs", function() {
fit("is focused and will run", function() {
expect(true).toBeTruthy();
});
it('is not focused and will not run', function(){
expect(true).toBeFalsy();
});
});
However, I don't really like the idea of editing my tests (fit and fdescribe) to run them selectively. I prefer to use a test runner like karma which can filter out tests using a regular expression.
Here's an example using grunt.
$ grunt karma:dev watch --grep=mypattern
If you're using gulp (which is my favourite task runner), you can pass args into gulp-karma with yargs and match patterns by setting karma's config.
Kinda like this:
var Args = function(yargs) {
var _match = yargs.m || yargs.match;
var _file = yargs.f || yargs.file;
return {
match: function() { if (_match) { return {args: ['--grep', _match]} } }
};
}(args.argv);
var Tasks = function() {
var test = function() {
return gulp.src(Files.testFiles)
.pipe(karma({ configFile: 'karma.conf.js', client: Args.match()}))
.on('error', function(err) { throw err; });
};
return {
test: function() { return test() }
}
}(Args);
gulp.task('default', ['build'], Tasks.test);
See my gist: https://gist.github.com/rimian/0f9b88266a0f63696f21
So now, I can run a single spec using the description:
My local test run: (Executed 1 of 14 (skipped 13))
gulp -m 'triggers the event when the API returns success'

Also see: https://github.com/karma-runner/karma-jasmine
For anyone stumbling upon this, a better approach, which you can set up from the code itself, is to use this plugin: https://github.com/davemo/jasmine-only
It allows you set the spec exclusivity right on the code like this:
describe.only("MySpec", function() {
it('function 1', function() {
//...
})
it.only('function 2', function() {
//...
}
})
// This won't be run if there are specs using describe.only/ddescribe or it.only/iit
describe("Spec 2", function(){})
There has been a long discussion to get this added to Jasmine core, see: https://github.com/pivotal/jasmine/pull/309
If you happen to be using Jasmine via Karma/Testacular you should already have access to ddescribe() and iit()
You can create your all your specs up front but disable them with xdescribe and xit until you're ready to test them.
describe('BuckRogers', function () {
it('shoots aliens', function () {
// this will be tested
});
xit('rescues women', function () {
// this won't
});
});
// this whole function will be ignored
xdescribe('Alien', function () {
it('dies when shot', function () {
});
});
This is the most simplified answer with a practical example .Even in fdescribe you can run few it blocks using it. f means focus.
Also in a none fdescribe block which is just describe, you can select only specific it blocks by marking them as fit.
Please run the below code and observe the console log, also read the comments in the code.
Read this author's article it helps too . https://davidtang.io/2016/01/03/controlling-which-tests-run-in-jasmine.html
//If you want to run few describe only add f so using focus those describe blocks and it's it block get run
fdescribe("focus description i get run with all my it blocks ", function() {
it("1 it in fdescribe get executed", function() {
console.log("1 it in fdescribe get executed unless no fit within describe");
});
it("2 it in fdescribe get executed", function() {
console.log("2 it in fdescribe get executed unless no fit within describe");
});
//but if you and fit in fdescribe block only the fit blocks get executed
fit("3 only fit blocks in fdescribe get executed", function() {
console.log("If there is a fit in fdescribe only fit blocks get executed");
});
});
describe("none description i get skipped with all my it blocks ", function() {
it("1 it in none describe get skipped", function() {
console.log("1 it in none describe get skipped");
});
it("2 it in none describe get skipped", function() {
console.log("2 it in none describe get skipped");
});
//What happen if we had fit in a none fdescribe block will it get run ? yes
fit("3 fit in none describe get executed too eventhough it;s just describe ", function() {
console.log("3 fit in none describe get executed too");
});
});
With stand-alone Jasmine(2.0.0), on the spec_runner.htlm, I could click a specific spec and focus on that one spec. I should have noticed this feature earlier.
Not exactly what you've asked for but adding iit will test only that particular spec and ignore all others in the file, ddescribe works in the same way. So you can focus on a particular spec using iit or ddescribe
