serenity-js- How to use before and after hooks - cucumberjs

How to use before and after hooks in serenity-js, without using Mocha? Any sample code available in the cook book?

Handling before and after hooks is the responsibility of a test runner, rather than Serenity/JS itself.
You can find out more in the documentation of both of the supported test runners:
Cucumber - https://github.com/cucumber/cucumber-js/blob/1.x/docs/support_files/hooks.md
Mocha - https://mochajs.org/#hooks
Hope this helps!

how generate logs and reports in ruby capybara rspec

I am new to this technology and I am working on an automation framework, ruby-capybara-rspec. And this project is in POC state. Now I want to generate "Logs" and "reports" as well. Please help me if there is any default/inbuilt functionality to do so or is there any specific gem I can use to achieve it. Thank you in advance.
PS: There is no specific ask from the client so I can bring my own logging and report to this framework.
From the official documentation:
rspec example_spec.rb --format documentation --out rspec.txt

Why we need `afterEach(cleanup);`?

This is question about unit test (jest + #testing-library/react)
Hi. I started using #nrwl/react these days.
This is amazing products and I'm excited monorepos project with nx.
Btw, there is afterEach(cleanup); in generated template test file.
This is my sample project.
https://github.com/tyankatsu0105/reproducibility-react-test-nx/blob/master/apps/client/src/app/app.spec.tsx#L7
However react-testing-library doesn't need cleanup when using jest.
https://testing-library.com/docs/react-testing-library/api#cleanup
Please note that this is done automatically if the testing framework you're using supports the afterEach global (like mocha, Jest, and Jasmine). If not, you will need to do manual cleanups after each test.
In fact, I see error when remove afterEach(cleanup); from test files.
Found multiple elements with the text:
thanks!

Custom code for #javascript tags in Capybara Webkit

I have some test set up code that I need to run before any Capybara tests that are running JavaScript with the #javascript tag. I don't want the code to run the rest of the time since this test set up is expensive in terms of system resources and cognitive load.
I've searched the documentation extensively and was unable to find any examples of running arbitrary ruby before tests based in tagging. Can anyone help me out?
Edit: after thinking about this some more, I only need the code to run once before any tests are run, so this is probably a simpler problem then I first described.
Since you're asking about an #javascript tag I'm assuming you're talking about Cucumber driven tests, if you're not then please clarify.
To run code before a test you use Before
Before('#javascript') do
# any code here will get run before each test tagged with #javascript
end
To make it only run that code once you'd need to use a global variable
Before('#javascript') do
$already_run ||= false
return $already_run if $already_run
# code here will get run once before the first test tagged #javascript
$already_run = true
end

Stop jasmine test after first expect fails

I'm familiar with python unittest tests where if an assertion fails, that test is marked as "failed" and it moves on to other tests. Jasmine on the other hand will continue through all expects even if the one of them fails. How can I make Jasmine stop processing a test after the first expectation fails?
it ("shouldn't need to test other expects if the first fails", function() {
expect(array.length).toBe(1);
// don't need to check this if the first failed.
expect(array[0]).toBe("foo");
});
Am I thinking about it wrong? I have some tests with lots of expect's and it seems like a waste to show all the stack traces when only the first is wrong really.
#Gregg's answer was correct for the latest version of Jasmine at that time (v2.0.0).
However, since then, this new feature was added in v2.3.0:
Allow user to stop a specs execution when an expectation fails (Fixes #577)
It's activated by adding throwFailures=true to the query string of the runner page, eg:
http://localhost:8000/?throwFailures=true
Jasmine doesn't support failing early, in a single spec. The idea is to give you all of the failures in case that helps figure out what is really wrong in your spec.
Jasmine has stop on failure feature and you can check it here:
https://plnkr.co/plunk/Ko5m6MQz9VUPMMrC
This starts jasmine with oneFailurePerSpec property.
According to the comments of https://github.com/jasmine/jasmine/issues/414 I figured out that 2 solutions exists for this:
https://github.com/radialanalytics/protractor-jasmine2-fail-whale
https://github.com/Updater/jasmine-fail-fast
I just started to use the protractor-jasmine2-fail-whale because it seems to have more features. Although to take screenshots in case of test failures I currently use protractor-jasmine2-html-reporter.
I'm using Jasmine in Appium (a tool to test React Native apps).
I fixed the issue by adding stopSpecOnExpectationFailure=true to Jasmine configs
jasmine v3.8.0 & jasmine-core v3.8.0

Meteor test driven development [closed]

Closed. This question needs to be more focused. It is not currently accepting answers.
Want to improve this question? Update the question so it focuses on one problem only by editing this post.
Closed 5 years ago.
Improve this question
I don't see how to do test driven development in meteor.
I don't see it mentioned anywhere in documentation or FAQ. I don't see any examples or anything like that.
I see that some packages are using Tinytest.
I would need response from developers, what is roadmap regarding this. Something along the lines of:
possible, no documentation, figure it out yourself
meteor is not built in a way that you can make testable apps
this is planned feature
etc
Update 3: As of Meteor 1.3, meteor includes a testing guide with step-by-step instructions for unit, integration, acceptance, and load testing.
Update 2: As of November 9th, 2015, Velocity is no longer maintained. Xolv.io is focusing their efforts on Chimp, and the Meteor Development Group must choose an official testing framework.
Update: Velocity is Meteor's official testing solution as of 0.8.1.
Not much has been written about automated testing with Meteor at this time. I expect the Meteor community to evolve testing best-practices before establishing anything in the official documentation. After all, Meteor reached 0.5 this week, and things are still changing rapidly.
The good news: you can use Node.js testing tools with Meteor.
For my Meteor project, I run my unit tests with Mocha using Chai for assertions. If you don't need Chai's full feature set, I recommend using should.js instead. I only have unit tests at the moment, though you can write integration tests with Mocha as well.
Be sure to place your tests in the "tests" folder so that Meteor does not attempt to execute your tests.
Mocha supports CoffeeScript, my choice of scripting language for Meteor projects. Here's a sample Cakefile with tasks for running your Mocha tests. If you are using JS with Meteor, feel free to adapt the commands for a Makefile.
Your Meteor models will need a slight bit of modification to expose themselves to Mocha, and this requires some knowledge of how Node.js works. Think of each Node.js file as being executed within its own scope. Meteor automatically exposes objects in different files to one another, but ordinary Node applications—like Mocha—do not do this. To make our models testable by Mocha, export each Meteor model with the following CoffeeScript pattern:
# Export our class to Node.js when running
# other modules, e.g. our Mocha tests
#
# Place this at the bottom of our Model.coffee
# file after our Model class has been defined.
exports.Model = Model unless Meteor?
...and at the top of your Mocha test, import the model you wish to test:
# Need to use Coffeescript's destructuring to reference
# the object bound in the returned scope
# http://coffeescript.org/#destructuring
{Model} = require '../path/to/model'
With that, you can start writing and running unit tests with your Meteor project!
Hi all checkout laika - the whole new testing framework for meteor
http://arunoda.github.io/laika/
You can test both the server and client at once.
See some laika example here
See here for features
See concept behind laika
See Github Repository

I realize that this question is already answered, but I think this could use some more context, in the form of an additional answer providing said context.
I've been doing some app development with meteor, as well as package development, both by implementing a package for meteor core, as well as for atmosphere.
It sounds like your question might be actually a question in three parts:
How does one run the entire meteor test suite?
How does one write and run tests for individual smart packages?
How does one write and run tests for his own application?
And, it also sounds like there may be a bonus question in there somewhere:
4. How can one implement continuous integration for 1, 2, and 3?
I have been talking and begun collaborating with Naomi Seyfer (#sixolet) on the meteor core team to help get definitive answers to all of these questions into the documentation.
I had submitted an initial pull request addressing 1 and 2 to meteor core: https://github.com/meteor/meteor/pull/573.
I had also recently answered this question:
How do you run the meteor tests?
I think that #Blackcoat has definitively answered 3, above.
As for the bonus, 4, I would suggest using circleci.com at least to do continuous integration for your own apps. They currently support the use case that #Blackcoat had described. I have a project in which I've successfully gotten tests written in coffeescript to run unit tests with mocha, pretty much as #Blackcoat had described.
For continuous integration on meteor core, and smart packages, Naomi Seyfer and I are chatting with the founder of circleci to see if we can get something awesome implemented in the near term.
RTD has now been deprecated and replaced by Velocity, which is the official testing framework for Meteor 1.0. Documentation is still relatively new as Velocity is under heavy development. You can find some more information on the Velocity Github repo, the Velocity Homepage and The Meteor Testing Manual (paid content)
Disclaimer: I'm one of the core team members of Velocity and the author of the book.
Check out RTD, a full testing framework for Meteor here rtd.xolv.io.
It supports Jasmine/Mocha/custom and works with both plain JS and coffee. It includes test coverage too that combines unit/server/client coverage.
And an example project here
A blog to explain unit testing with Meteor here
An e2e acceptance testing approach using Selenium WebdriverJS and Meteor here
Hope that helps. Disclaimer: I am the author of RTD.
I used this page a lot and tried all of the answers, but from my beginner's starting point, I found them quite confusing. Once I had any trouble, I was flummoxed as to how to fix them.
This solution is really simple to get started with, if not fully documented yet, so I recommend it for people like myself who want to do TDD but aren't sure how testing in JavaScript works and which libraries plug into what:
https://github.com/mad-eye/meteor-mocha-web
FYI, I found that I also need to use the router Atmosphere package to make a '/tests' route to run and display the results from the tests, as I didn't want it to clutter my app every time it loads.
About the usage of tinytest, you may want to take a look at those useful ressources:
The basics are explained in this screencast:
https://www.eventedmind.com/feed/meteor-testing-packages-with-tinytest
Once you understood the idea, you'll want the public API documentation for tinytest. For now, the only documentation for that is at the end of the source of the tinytest package: https://github.com/meteor/meteor/tree/devel/packages/tinytest
Also, the screencast talks about test-helpers, you may want to have a look at all the available helpers in here:
https://github.com/meteor/meteor/tree/devel/packages/test-helpers
There often is some documentation inside each file
Digging in the existing tests of meteor's packages will provide a lot of examples. One way of doing this is to make a search for Tinytest. or test. in the package directory of meteor's source code
Testing becomes a core part of Meteor in the upcoming 1.3 release. The initial solution is based on Mocha and Chai.
The original discussions of the minimum viable design can be found here and the details of the first implementation can be found here.
MDG have produced the initial bones of the guide documentation for the testing which can be found here, and there are some example tests here.
This is an example of a publication test from the link above:
it('sends all todos for a public list when logged in', (done) => {
const collector = new PublicationCollector({userId});
collector.collect('Todos.inList', publicList._id, (collections) => {
chai.assert.equal(collections.Todos.length, 3);
done();
});
});
I'm doing functional/integration tests with Meteor + Mocha in the browser. I have something along the lines of the following (in coffeescript for better readability):
On the client...
Meteor.startup ->
Meteor.call 'shouldTest', (err, shouldTest) ->
if err? then throw err
if shouldTest then runTests()
# Dynamically load and run mocha. I factored this out in a separate method so
# that I can (re-)run the tests from the console whenever I like.
# NB: This assumes that you have your mocha/chai scripts in .../public/mocha.
# You can point to a CDN, too.
runTests = ->
$('head').append('<link href="/mocha/mocha.css" rel="stylesheet" />')
$.getScript '/mocha/mocha.js', ->
$.getScript '/mocha/chai.js', ->
$('body').append('<div id="mocha"> </div>')
chai.should() # ... or assert or explain ...
mocha.setup 'bdd'
loadSpecs() # This function contains your actual describe(), etc. calls.
mocha.run()
...and on the server:
Meteor.methods 'shouldTest': -> true unless Meteor.settings.noTests # ... or whatever.
Of course you can do your client-side unit testing in the same way. For integration testing it's nice to have all Meteor infrastructure around, though.
As Blackcout said, Velocity is the official TDD framework for Meteor. But at this moment velocity's webpage doesn't offer good documentation. So I recommend you to watch:
Concept behind velocity
Step by step tutorial
And specially the Official examples
Another option, made easily available since 0.6.0, is to run your entire app out of local smart packages, with a bare minimum amount of code outside of packages to boot your app (possibly invoking a particular smart package that is the foundation of your app).
You can then leverage Meteor's Tinytest, which is great for testing Meteor apps.
Ive successfully been using xolvio:cucumber and velocity to do my testing. Works really well and runs continuously so you can always see that your tests are passing.
Meteor + TheIntern
Somehow I managed to test Meteor application with TheIntern.js.
Though it is as per my need. But still I think it may lead someone to the right direction and I am sharing what I have done to resolve this issue.
There is a execute function which allows us to run JS code thorugh which we can access browsers window object and hence Meteor also.
Want to know more about execute
This is how my test suite looks for Functional Testing
define(function (require) {
var registerSuite = require('intern!object');
var assert = require('intern/chai!assert');
registerSuite({
name: 'index',
'greeting form': function () {
var rem = this.remote;
return this.remote
.get(require.toUrl('localhost:3000'))
.setFindTimeout(5000)
.execute(function() {
console.log("browser window object", window)
return Products.find({}).fetch().length
})
.then(function (text) {
console.log(text)
assert.strictEqual(text, 2,
'Yes I can access Meteor and its Collections');
});
}
});
});
To know more, this is my gist
Note: I am still in very early phase with this solution. I don't know whether I can do complex testing with this or not. But i am pretty much confident about it.
Velocity is not mature yet. I am facing setTimeout issues to use velocity. For server side unit testing you can use this package.
It is faster than velocity. Velocity requires a huge time when I test any spec with a login. With Jasmine code we can test any server side method and publication.
