Is there a reliable way to have Cypress exit as soon as a test fails?
2022 here and tested with cypress version: "6.x.x"
until "10.x.x"
You could use { force: true }
like:
cy.get("YOUR_SELECTOR").click({ force: true });
but this might not solve it ! The problem might be more complex, that's why check below
My solution:
cy.get("YOUR_SELECTOR").trigger("click");
Explanation:
In my case, I needed to watch a bit deeper what's going on. I started by pin the click
action like this:
Then watch the console, and you should see something like:
Now click on line Mouse Events
, it should display a table:
So basically, when Cypress executes the click
function, it triggers all those events but somehow my component behave the way that it is detached the moment where click event
is triggered.
So I just simplified the click by doing:
cy.get("YOUR_SELECTOR").trigger("click");
And it worked ????
Hope this will fix your issue or at least help you debug and understand what's wrong.

When it comes to web automation testing, the first automation testing framework that comes to mind undoubtedly has to be the Selenium framework. Selenium automation testing has picked up a significant pace since the creation of the framework way back in 2004.
We just raised $45 million in a venture round led by Premji Invest with participation from existing investors. Here’s what we intend to do with the money.
Find element by Text in Selenium is used to locate a web element using its text attribute. The text value is used mostly when the basic element identification properties such as ID or Class are dynamic in nature, making it hard to locate the web element.
We are nearing towards the end of 2019, where we are witnessing the introduction of more aligned JavaScript engines from major browser vendors. Which often strikes a major question in the back of our heads as web-developers or web-testers, and that is, whether cross browser testing is still relevant? If all the major browser would move towards a standardized process while configuring their JavaScript engines or browser engines then the chances of browser compatibility issues are bound to decrease right? But does that mean that we can simply ignore cross browser testing?
Web products of top-notch quality can only be realized when the emphasis is laid on every aspect of the product. This is where web automation testing plays a major role in testing the features of the product inside-out. A majority of the web testing community (including myself) have been using the Selenium test automation framework for realizing different forms of web testing (e.g., cross browser testing, functional testing, etc.).
Cypress is a renowned Javascript-based open-source, easy-to-use end-to-end testing framework primarily used for testing web applications. Cypress is a relatively new player in the automation testing space and has been gaining much traction lately, as evidenced by the number of Forks (2.7K) and Stars (42.1K) for the project. LambdaTest’s Cypress Tutorial covers step-by-step guides that will help you learn from the basics till you run automation tests on LambdaTest.
You can elevate your expertise with end-to-end testing using the Cypress automation framework and stay one step ahead in your career by earning a Cypress certification. Check out our Cypress 101 Certification.
Watch this 3 hours of complete tutorial to learn the basics of Cypress and various Cypress commands with the Cypress testing at LambdaTest.
