I use Cypress now for all my projects and combined with Typescript it’s the only testing I do. No unit or component testing as I find this combination catch’s the majority of issues and it’s it’s fast to develop and maintain.
Good, through run though thanks for sharing
For those using cypress for E2E testing do you simply mock all your API calls?
Has anyone found a testing strategy similar to how RoR does it? Specifically, a test database that gets reset after every run?
I just hate mocking every single endpoint in JS projects that heavily rely on multiple microservices. It becomes an exercise in tedium.
In rails you normally can use
FactoryBotthrough middleware on server side andcommandsto clean/setup specs in cypress. Doing calls to your real app makes everything updated, no need to write mocks, especially it can be a problem for websocket apps (not enough tools for now to mock websocket). So in other words you are doing integration testing, which is higher level, with easiness of unit testing - which is absolutely great and fast enough.One of the solutions: github.com/shakacode/cypress-on-rails
I do also like to test the middle-ware directly.
It forces you to keep all the logic away from client code.
If someone implements part of the business logic with a javascript in the browser ... that is not secure and might not end well in some cases.
My opinion is that the browser code should be used only for usability requirements. And those use cases need also test, so +1 for cypress for helping on that.
Nevertheless the middleware / APIs should be tested directly, also for preventing those invalid input cases that the interface might never send, but that might break everything.
Do you define all your interfaces by hand ?
In the case of REST endpoints, the same code generator (Ex: openapi-generator) that generate the endpoints from the API specs (Ex: OpenAPI) might generate the client library with basic unit tests.
I recommend using Cypress Testing Library to extend the commands cypress can use. I very rarely use
cy.getand instead use the commands that Cypress Testing Library gives you.You can do things like
cy.findByPlaceholderText,cy.findByText, orcy.findByTestIdfor hard to grab elements. And retries are built in if I remember correctly.If you have more than one element that matches you can just add
Allafter the find, for examplecy.findAllByTextand if you want to grab the first you'd docy.findAllByText("hello button").eq(0).click()testing-library.com/docs/cypress-t...
Hi Bushra,
Thank you for the very good article. I am new to cypress and javascript. please help me with below code. trying to get latest string value and compare it in while loop. but in while loop it keeps picking up old string value.
Thanking you in advance. Really appreciate your help.
allOpenCases.getCurrentSystemStep().then(($currentStep)=>
{
return $currentStep.text()
}).as('CSS')
cy.get('@CSS').then((cStep)=>{
let count = 1
while(cStep!==targetSystemStep && count < 50)
{
allOpenCases.getSearchButton().click()
cy.wait(3000)
allOpenCases.getCurrentSystemStep().then(function($currentStep)
{
let cStep = $currentStep.text() //latest text
})
count ++
}
})
Uh, using Cypress is such a bad experience.
I tried it because a colleague heard about the hype.
All your posts seem to be related to Cypress.
Why is that?
I just finished figuring out how use Cypress combined with XState for auto-generated model based tests. I also wanted to mock API responses a little differently than Cypress suppports out-of-the-box currently but I was able to make it work. I really like that I can review the test at each stage with Cypress. Anyways I posted about my experience here: dev.to/rjdestigter/model-based-ui-...
Agree Cypress is evolving however it can be fit everywhere. Not sure but it does not provide a free hand in using all the JS capabilities like in wdio. working with nested iframes is a pain. I don't want to change/manipulate the dom just to handle the new window opened by a link.
Also, on the architecture, I am not able to launch the url hubspot.com/ in Cypress but in wdio or playwright that's not a issue
We've been using Cypress for now one and a half year. It's very good and easy to use
Awesome! Thank you so much for sharing. I'm trying to implement Cypress in our React App.
There are just few things I don't get... should we use our real graphql service (in my case) to test the data or it's better to mock the graphql requests??
If we should mock the service data.. it's not complicated to maintain the tests every time the requirements changes? Thanks in advance!
It was an awesome description as well as a great read through tutorial.
Thanks Bushra Alam for such a simple got through post.
Need an advise for E2E Testing, if we have a frontend and backend both.
For using Cypress on frontend ,i will be needing my backend server running as well.So, how to manage frontend,backend and Cypress in CI?
Any advise is appreciated.
Thanks Again!!
My project is trying to get automated UI testing setup. I might try this out. Thanks for the introduction.
I heard TestCafe is in vogue now.
thank you for sharing nice blog
Very useful article. Thank Bushra
