Test cases for an application which has both php and javascript - jasmine

There is an application which uses both php and javascript. If I want to write test cases for this application. Shall I have to write both (phpunit test cases for php code and jasmine test cases for javascript code)? .
I have downloaded phpunit from the link https://phar.phpunit.de/phpunit.phar
I am just not clear how to start the test cases.Please help .
From the link https://softwareengineering.stackexchange.com/questions/28306/can-i-test-effectively-javascript-functions-with-a-php-unit-testing-framework , they say I have to write javascript test cases for javascript code and php test cases for php code. But my javascript code is in between php code. How can I write and execute the test cases?

The first important concept is: to be tested, your code must be run, and for that you have to use the environment needed for each case:
for php: usually the php command line executable
for Javascript: a real browser, a headless browser like PhantomJS, or node.js
Once you have this clear, it's easy to understand how to setup the tests. Use PHPUnit for testing your php files and classes, and your Javascript framework of choice for testing Javascript code.
Regarding Javascript code being mixed with php code:
Strictly, the Javascript code will finally be sent to the browser, even if it is being written by php. So it should be testable running it in a Javascript environment.
But in reality, this probably is an indication of a poorly structured app, in which Javascript code is not separated from the backend code, and probably does not use objects and separation of concerns. This will make the code quite hard to test.
IMO the hardest part of testing is being able to write testable code, not writing the actual tests. If your code does not uses objects, some kind of dependency injection, templates for writing the HTML and the Javascript code is not fully separated from the backend code, I'd say you'll have a bad time trying to test it. My advice is that you rewrite some part of your app using best practices and try to test it. Using a framework usually helps because frameworks enforce the separation of concerns and usually have unit testing integrated.

How do you test response contains string in Inertia unit tests?

I am using Inertia and would like to run some tests to check whether the response contains a certain string.
->assertInertia(
fn (AssertableInertia $page) => $page->component('UsersPage')->has('profile')->dd('profile.0.buttons')
);
so the above works and i can dump the profile.0.buttons and see the string i want to check for, but how do i automatically test that this string exists? normal unit tests, i'd use assertSee. whereContains also doesn't work.
I think that Inertia page about testing has done a great job in summing the testing option for Laravel/Inertia.
Endpoint tests (assertInertia) are feature tests, and you can use them to check if a controller is sending the right components and data to Inertia.
Your question is going more in the direction of "Client-side unit tests" e.g. Jest, where you can send some data to React/Vue component and see how that data has been rendered.
There are "End-to-end tests": Cypress is great but lacks nice integration with setting up Laravel enviroment and seeders in test.
That leave us with Laravel Dusk. I love this tool because it give us best of both worlds (backend and frontend).
You can set up your test with seeders or Model factories, and in the same test you can fire up virtual browser and see how Inertia rendered page. Best thing is that you can use helpers for typing and clicking so you can realy test your app and how it behaves.

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.

One set of tests for few projects with different parameters

i'm using Protractor and Jasmine and would like to organize my E2E test in the best way.
Example:
There is a set of the tests for check registration function (registration with right credentials, register as existed user, etc.).
I need to run those tests in three different projects. Tests are same, but credentials are different. For one project it could be 3 fields in the registration form, in another one - 6.
Now everything is organized in a very complicated way:
each single test is made not as "it" but as a function
there is a function which contains all tests (functions which test)
there is a file with Describe function in each
in that file there is one "it" which call the function which contains all tests
there is test suite for each project
I believe that there is a practice how to organize everything in a right way, that each test was in own "it". So will be happy to see some links or advice.
Thank you in advance!
Since it's a broad question, i will redirect you to few links. You should probably be looking at page-object model of Protractor. It will help you simplify and set a standard to organise your tests in a way that is readable and easy to use. Here's the link to it as described by Protractor team.
page-object model
However if you want to know why do we need to use such a framework, there are many shortcomings to it, which can be solved by using such framework. A detailed explanation is here
shortcomings of protractor and how to overcome them
EDIT: Based on your comments i feel that you are trying make a unified file/function that can cater to all the suites that will be using it. In order to handle such things try adding a generalised function (to fill form fields in your case), export that function and then require it into your test suites. Here's a sample link to it -
Exports and require
Hope this helps.

Rails rspec controller test vs integration test

I just completed writing a detailed rspec capybara integration and unit tests for Rails app, which includes mocking Omniauth (twitter) login, filling in forms, data validations, etc. However, I am wondering whether there is a need to write a separate controller or functional test.
Would appreciate your input and any links to further readings etc.
I'll play devil's advocate here, since I know I'm probably in the minority with this opinion: I actually prefer to do exceedingly thorough controller testing. A few reasons:
1) I find it easier to systematically test every path and outcome at the controller level than at the integration test level. My integration tests are primarily just happy-paths, and some of the more common error paths.
2) A lot of potential security issues occur at the controller level. Thorough testing helps me ensure that nothing malicious can get through to my model logic.
3) This is subjective, but it really forces me to think about some of the long-tail paths that my application might go through. What if someone tries to for an invalid password reset token into the URL? Controller testing ensures that I consider all options.
4) Unlike integration tests, they're fairly straight-forward to test. Each action is just a ruby method!
Personally, I think if your request (integration) spec is exercising all code paths you're covered. Ryan Bates has a great Railscast about how he tests here: http://railscasts.com/episodes/275-how-i-test?autoplay=true and about 5:05 in he says a similar thing. Like you I like to write integration tests rather than controller specs. Most of the time controllers simply front CRUD type operations anyway (especially if you're careful about keeping domain logic out of the controller), so all you're testing is the scaffolding.

Testing CodeIgniter controllers

We are creating a RESTful API using CodeIgniter and I'm trying to determine how to create tests for the controllers. The controllers take some input from a client app, perform some business logic using one or more models, then output JSON.
The purpose of the tests is primarily regression testing-- to make sure that client-side engineers who are not principally web/php developers don't break something if they need to touch server code.
How would you test a controller action in CI?
I currently have two ideas:
1.) Create a test function/class that does its setup with the database then calls the controller via curl, simulating the behavior of the client.
2.) Don't test controllers, keep all logic in the models and write tests for the models.
Any thoughts on which will be more robust/easier to use? (or additional suggestions?)
As well as CodeIgniter's own testing library (CodeIgniter 2) it is possible to use PHPUnit with CodeIgniter with FooStack. If you're using CodeIgniter 2.x, it's not as straightforward to integrate as it was in CodeIgniter 1.x but I have seen it done.
FooStack itself comes with example tests covering both models and controllers, among other things, and can give you a good starting point.
Another way to test your controller, which you've said is returning JSON, might be to use the Selenium IDE. This would allow you to run simple tests that check the required input returns the expected output without worrying how it's done. FooStack or the unit testing library would probably give you a more coverage and confidence though.
If you want quality testing you need both.
One to test your code and how it handles with errors
and one to test how client itself would see potential issues.
You can validate controller also through passing the form data to your test controller like
$_POST['name'] = 'testuser';
$this->CI->index_post();
$data = output();
# Decode Response data
$actualArray = json_decode($data, true);
$this->assertNotEmpty($actualArray['status'], 'Status is empty');
like this you can validate your controller through your test/controller.
