drone.io headless dartium testing - unit-testing

Can you run browser based unit tests for Dart on drone.io? my last failed build is here. I tried sudo start xvfb but I'm not sure how to point that to my index.html file that launches my unit tests, anyone know how to do this? I should say that I am in no way interested in any actual DOM testing but my library imports 'dart:html' so I can't run it in the basic dart vm only configuration.

Update: Modified the build script to download content_shell. Also updated the path to content_shell in the hop task createUnitTestTask().
I use the hop pub package to do headless testing for drone. You can refer to the simplot library for a relatively simple example. But the steps are basically to add the following to your pubspec.yaml as developer dependencies:
hop: '>=0.27.0'
unittest: '>=0.9.0 <0.10.0'
Create a tool directory in your project root and add a file hop_runner.dart. Mine looks something like this:
library dumprendertree;
import 'package:hop/hop.dart';
import 'dart:io';
import 'dart:async';
main(List<String> args) {
addTask('test', createUnitTestTask());
runHop(args);
}
Task createUnitTestTask() {
return new Task((TaskContext tcontext) {
tcontext.info("Running Unit Tests....");
var result = Process.run('./content_shell',
['--dump-render-tree','test/simplot_tests.html'])
.then((ProcessResult process) {
tcontext.info(process.stdout);
});
return result;
});
}
You can see where it is calling my simplot_tests.html file in the test directory.
Then my drone script is:
$DART_SDK/../chromium/download_contentshell.sh
unzip content_shell-linux-x64-release.zip
mv drt*/* .
pub get
sudo start xvfb
dart --checked tool/hop_runner.dart test
The simplot_tests.html file looks like the following:
<!DOCTYPE html>
<html>
<head>
<title>Unit Tests for Simplot Library</title>
</head>
<body>
<script type="text/javascript" src="packages/unittest/test_controller.js"></script>
<script type="text/javascript" src="packages/browser/dart.js"></script>
<script type="application/dart" src="simplot_tests.dart"></script>
</body>
</html>
And finally, the dart file looks something like this:
import 'package:simplot/simplot.dart';
import 'package:unittest/unittest.dart';
import 'package:unittest/html_enhanced_config.dart';
import 'dart:html';
import 'dart:math';
part 'tests/logarithmic_tests.dart';
part 'tests/time_stamp_tests.dart';
part 'tests/axis_configure_tests.dart';
part 'tests/create_single_plot.dart';
part 'tests/create_multiple_plots.dart';
part '../lib/src/axis_config.dart';
void main() {
print('Running unit tests for simplot library.');
useHtmlEnhancedConfiguration();
group('All Tests:', (){
test('test of logarithmic functions', () => logarithmicTests());
test('test of time stamp', () => timeStampTests());
test('test of axis configuration', () => axisConfigTests());
test('test of creating a single plot', () => createSinglePlot());
test('test of creating multiple plots', () => createMultiplePlots());
});
}
Hopefully, that should get you started.

This is my Drone script for the xml2json library
pub install
sudo start xvfb
content_shell --args --dump-render-tree test/xml2json.html | sed -n 2p | grep PASS
It uses standard HTML based unit testing, ie includes htmlconfiguration().
The grep is just to check for pass/fail, you may not need this.

Can't Figure out the Syntax Error in App.js

I am using this tutorial to install React for the front with an API built in Django.
https://sweetcode.io/how-use-djang-react-ap/
My repository for this projects so far is here:
https://github.com/AlexMercedCoder/DjangoReactCRM
When I npm run dev I get a syntax error in App.js, I've played with it and can't seem to figure it out. The error I get is.
ERROR in ./frontend/src/components/App.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
SyntaxError:
C:\Users\alexm\projects\DjangoReactCRM\drcrm\frontend\src
\components\App.js: Unexpected token, expected "," (29:6)
27 |
28 | wrapper ? ReactDOM.render(<app>, wrapper) : null;
> 29 | </app>
App.js
import React, { Component } from "react";
import ReactDOM from "react-dom";
class App extends Component {
state = {
data: ''
};
componentDidMount() {
fetch("/api")
.then(response => {
return response.json();
})
.then(data => this.setState({ data: JSON.stringify(data)}));
}
render(){
return (
<p>Jason data = {this.state.data}</p>
)
}
}
wrapper ? ReactDOM.render(<app>, wrapper) : null;
</app>
First, the <app> component is closed outside the ternary operator, so you'd have to use <app></ app> or even simpler <app />.
wrapper ? ReactDOM.render(<app></app>, wrapper) : null;
or
wrapper ? ReactDOM.render(<app/>, wrapper) : null;
Then, all React components must start with a capital letter
to differentiate default DOM component from those created with React, so you have to use this notation.
wrapper ? ReactDOM.render(<App />, wrapper) : null;
Finally, I do not see the utility of the ternary operator at the end of your code. Normally, the second argument when we call reactDOM.render(X, Y) must represent the DOM element in which we will render our main React component (in this case, <App />).
By default, when we create a React project with create-react-app, we don't have to deal with these settings and the DOM element is automatically defined as <div id='root'></div> (check inside the <body> in public/index.html inside your project root).
So call document.getElementById('root') to get the DOM element and simply put the result as second argument.
ReactDOM.render(<App />, document.getElementById('root'));
If it persist, I suggest you to simply create another React project with create-react-app and copy/paste only the code you need.

I hope it can help you.
** I apologize if my explanations are not clear or if I made some mistakes.
There are three problems in your component.
I'm guessing wrapper was supposed to be document.getElementById("root") ? Even then the ternary condition doesn't make sense. It should be something like:
ReactDOM.render(
<App />,
document.getElementById("root")
)
You defined the component as App, yet in ReactDOM.render you are using app
You have </app> at the end of the file. It doesn't do anything in this case.

How to mock global Vue.js variable in JEST test

I have a global property/variable with my app urls:
Vue.prototype.$apiUrls = {
root: 'http://localhost:8080/',
api: 'api/v1/'
// etc.
}
I use it inside my components as axios request:
axios.get(`${this.$apiUrls.root}${this.$apiUrls.api}/users/`)
Now I want to test my component's code, I've mocked axios already, but still I receive an error:
TypeError: Cannot read property '$apiUrls' of undefined
I've tried to define/mock this property inside each test and/or in JEST's setup file, like e.g.
global.$apiUrls = {...}
// or
Vue.prototype.$apiUrls = {...}
// or
Object.defineProperties(Vue.prototype, {$apiUrls: {...}})
I've also tried mocking it to window or this (yeah, thats silly), but with no success - I still receive that error - please help.
There is two ways to achieve this. One is using the Config option, as mentioned by #Aldarund. You can read about it here.
If you are using Jest, I recommend doing this in the jest.init.js file:
import { config } from '#vue/test-utils'
config.mocks['$apiUrls'] = {
'some/endpoint'
}
Then add this to the jest section of your package.json:
"setupFiles": [
"<rootDir>/jest.init.js"
]
Now it is globally mocked. If you want to do this on a per test basis, you can use the mocks mounting option:
const wrapper = shallowMount(Foo, {
mocks: {
$apiUrls: 'some/endpoint'
}
})
Hopefully this helps!
If you are interested I am compiling a collection of simple guides on how to test Vue components here. It's under development, but feel free to ask make an issue if you need help with other related things to testing Vue components.
I don't think the answers above work anymore (in 2020).
Here's what worked for me:
For vue-test-utils 1.x.x (Vue 2)
Create a new file, name it eg. jest.init.js
Give it the following content:
import { config } from "#vue/test-utils";
config.mocks["yourGlobalProperty"] = label => label; //you can replace it with your own mock
Add this to your jest.config.js (actually write "rootDir", don't replace anything with a real path)
module.exports = {
setupFiles: ["<rootDir>/jest.init.js"]
}
These files will be only ran before jest runs unit tests.
Note that I'm importing {config}, not the default export. I don't know why the default didn't work for me. Even the documentation for vue test utils doesn't import the default export anymore
Also make sure you're not trying to import from the old vue-test-utils package. (The new one is #vue/test-utils)
For #vue/test-utils 2.x.x (vue-test-utils-next) (Vue 3)
Follow steps like for 1.x.x above, but in step two, do this instead:
import { config } from "#vue/test-utils"; //2.0.0-beta.5
config.global.mocks = {
yourGlobalProperty: label => label
};
You can do it with vue-test-utils beta 15 and later.
Here docs
And some example would be:
import VueTestUtils from '#vue/test-utils'
VueTestUtils.config.mocks['$apiUrls'] = {
...
}

Jest globalSetup option not working

I'm trying to make a function called loadFixtures available to all Jest tests.
I have the following line within the jest config object inside package.json:
"globalSetup": "<rootDir>/src/test/js/config/setup-globals.js"
setup-globals.js contains:
module.exports = function() {
function loadFixtures(filename) {
console.info('loadFixtures is working');
}
}
Within my tests I have, for example:
beforeEach(() => {
loadFixtures('tooltip-fixture.html');
});
However when I run Jest I get the following for each test:
ReferenceError: loadFixtures is not defined
I verified that the setup-globals.js file is definitely being found and loaded in by Jest before the tests execute.
Can anyone assist in identifying where I've gone wrong here? I've spent pretty much an entire day trying to debug without luck.
You should be using setupFiles and not globalSetup.
// jest config
"setupFiles": [
"<rootDir>/src/test/js/config/setup-globals.js"
]
then src/test/js/config/setup-globals.js:
global.loadFixtures(filename) {
console.info('loadFixtures is working');
}
references: https://medium.com/#justintulk/how-to-mock-an-external-library-in-jest-140ac7b210c2
If you bootstrapped your application using npx create-react-app (CRA), you do not need to add the setupFiles key under your jest key in the package.json file (CRA prevents overriding that key).
what you simply need to do is to add the file setupTests.js in the root of your SRC folder, and populate it with the snippet below:
import { configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';
configure({
adapter: new Adapter(),
});
remember you must have earlier installed the right versions of enzyme and enzyme-adapter-react
CRA has been wired to automatically load the setupTests.js file in the src folder if it exists. Hence after adding these, you can then go over to your test and do import {shallow} from enzyme without triggering an error.
if you are not using Create-react-app, all you need to do, in addition to adding the file above to your src folder is to add the key setupFiles into the jest key in your package.json. it should look like this:
"jest": {
"setupFiles": ['<rootDir>/src/setupTests.js'],
}
and you are good to go.
Cheers!
You're defining a function in a different scope. How about you create a separate module and import it directly in your test files. Or if you really want to define it in the global scope, try using the following code in your setup-globals.js file.
module.exports = function() {
global.loadFixtures = function(filename) {
console.info('loadFixtures is working');
}
}

Gulp-Inject Not Working

I have a simple Gulp build process setup for testing. I've read the documentation many times but I can't seem to get Gulp-inject to inject the scripts I want into an index.html file.
My Gulp file looks like this:
gulp.task('inject1', function() {
return gulp.src('app/index.html')
.pipe(inject(gulp.src('./app/scripts/app.js', {read : false}))) // Not necessary to read the files (will speed up things), we're only after their paths
.pipe(gulp.dest("dist"));
});
gulp.task('inject2', function() {
return gulp.src('app/scripts/**/*.js', {read : false}) // Not necessary to read the files (will speed up things), we're only after their paths
.pipe(inject("./app/index.html"))
.pipe(gulp.dest("./dist"));
});
This is part of my Index.html:
<!-- inject:js -->
<!-- endinject-->
Both of these are copied from the documentation on github.
When I run either of these tasks the console just says "Started 'inject' Finished 'Inject' '
In my ./dist folder it creates an Index.html file but no js files are injected.
I've tried typing in the src and inject properties many different way but no luck. Any idea what I'm doing wrong?
First of all you have a mistake in your endinject tag:
<!-- endinject-->
should be
<!-- endinject -->
This plugin has worked great for me and others in various settings, so the problem is probably in your configuration.
Because when you are using streaming, you cannot be sure which files you pipe along, always try to use a plugin to see exactly what files you are piping. I recommend using gulp-using. Try this to debug your setup:
var debug = require('gulp-debug');
gulp.task('inject2', function() {
return gulp.src('app/scripts/**/*.js', {read : false})
.pipe(debug())
.pipe(inject("./app/index.html"))
.pipe(gulp.dest("./dist"));
});
Also make sure you use the same method to verify that you match your html file as well.
Other than that - it's just trial and error until you understand piping to get just the right files with the correct path.
If gulp-inject isn't injecting any files, that means you didn't pipe them correctly, or your target inject was not correct. The plugin works, and works great for me.
If you need to see an example working gulp file, check out this this gulpfile.js gist
I had the same problem with the following code:
var injectSrc = gulp.src(['./public/css/*.css', '.public/js/*.js'], {read: false});
var injectOptions = {
ignorePath: '/public'
};
var options = {
bowerJson: require('./bower.json'),
directory: './public/lib',
ignorePath: '../../public'
}
gulp.task('inject', function() {
return gulp.src('./src/views/*.html')
.pipe(debug())
.pipe(wiredep(options))
.pipe(debug())
.pipe(inject(injectSrc, injectOptions))
.pipe(debug())
.pipe(gulp.dest('./src/views'));
});
My index.html had the following:
<!--bower:css-->
<!--endbower-->
<!--bower:js-->
<!--endbower-->
<!--inject:css-->
<!--endinject-->
<!--inject:js-->
<!--endinject-->
Click on this link to see what my file structure was.
The inject was creating the css files correctly but not the js files. Also the bower dependencies were working just fine.
Finally I caught the missing '/' in the array passed to gulp.src(). After fixing that to:
var injectSrc = gulp.src(['./public/css/*.css', './public/js/*.js'], {read: false});
it works correctly.

Testing service in Angular returns module is not defined

I am trying to run the default service unit test in my project (Taken from the Angular Seed project on GitHub), but I keep getting the error "module is not defined".
I have read that it could be something to do with the order of the referenced JavaScript files, but I can't seem to get it to work, so hopefully one of you might be able to help.
My configuration for the test looks like this:
basePath = '../';
files = [
'public/javascripts/lib/jquery-1.8.2.js',
'public/javascripts/lib/angular.js',
'public/javascripts/lib/angular-.js',
'public/app.js',
'public/controllers/.js',
'public/directives.js',
'public/filters.js',
'public/services.js',
JASMINE,
JASMINE_ADAPTER,
'public/javascripts/lib/angular-mocks.js',
'test/unit/*.js' ];
autoWatch = true;
browsers = ['Chrome'];
junitReporter = { outputFile: 'test_out/unit.xml', suite: 'unit'
};
The service looks like the following:
angular.module('myApp.services', []).
value('version', '0.1');
The test looks like this:
'use strict';
describe('service', function() {
beforeEach(module('myApp.services'));
describe('version', function() {
it('should return current version', inject(function(version) {
expect(version).toEqual('0.1');
}));
});
});
And the error when running the test through testacular is this:
ReferenceError: module is not defined
You are missing the angular-mocks.js file.
I had the same problem, and I understood why it wasn't working:
The jasmine.js javascript must be referenced BEFORE the angular-mocks.js file.
Indeed, the angular-mocks.js checks if Jasmine is loaded, and only if it is it will add the module function to the window.
Here is an extract of Angular Mocks code:
(Edit after the few comments about 'hacking' I had below: this is just an extract of the code, this is not something you need to write yourself, it's already there!)
window.jasmine && (function(window) {
[...]
window.module = angular.mock.module = function() {
var moduleFns = Array.prototype.slice.call(arguments, 0);
return isSpecRunning() ? workFn() : workFn;
/////////////////////
[...]
};
In a nutshell:
Just reference your jasmine.js before angular-mocks.js and off you go.
The window.module function comes in angular-mocks.js and is a shorthand for angular.mock.module. As mentioned in the docs, the module function only works with Jasmine.
Using Testacular, the following example configuration file will load angular-mocks.js.
/** example testacular.conf.js */
basePath = '../';
files = [
JASMINE,
JASMINE_ADAPTER,
'path/to/angular.js',
'path/to/angular-mocks.js', // for angular.mock.module and inject.
'src/js/**/*.js', // application sources
'test/unit/**/*.spec.js' // specs
];
autoWatch = true;
browsers = ['Chrome'];
And, as suggested elsewhere, you can run Testacular with debug logging to see what scripts are loaded (you can also see the same in the inspector):
testacular --log-level debug start config/testacular.conf.js
The angular.mock.inject docs include a pretty complete example.
We use 'module' without 'angular' in our unit tests and it works fine.
CoffeeScript:
describe 'DiscussionServicesSpec', ->
beforeEach module 'DiscussionServices'
beforeEach inject ... etc.
which compiles to
JavaScript:
describe('DiscussionServices', function() {
beforeEach(module('DiscussionServices'));
beforeEach(inject(function ... etc.
The only time I see something like the error you described is if in the testacular.conf.js file the angular-mocks.js file is not listed in the files section before the specs trying to use 'module'. If I put it after my tests in the 'files' list I get
ReferenceError: Can't find variable: module
(Our tests are being run through PhantomJS)
I had included angular-mocks.js in my karma config, but was still getting the error. It turns out the order is important in the files array. (duh) Just like in the head of an html doc, if a script calls angular before it's defined, and error occurs. So I just had to include my app.js after angular.js and angular-mocks.js.
If you're using Yeoman and its angular-generator, you probably get this error. Especially when you do the Tutorial ( ._.)
I fixed it, by copying the angular-mocks.js file, from the bower_components/angular-mocks dir to the test/mock dir. Of course you have to be sure, that your karma.conf.js file is configured correctly.
Greetings!
I had this same issue when I was doing something like var module = angular.module('my',[]). I needed to make sure it was surrounded by IIFE
