Validating Button Clicks in Cypress: Enable and Disable Functionality Explained

In modern web applications, validating user interactions is crucial for delivering a seamless user experience. One common scenario involves enabling or disabling buttons based on certain conditions, such as the presence of slides in a carousel. This post will guide you through how to validate button clicks using Cypress, ensuring buttons respond correctly to user actions only when appropriate.

The Problem: Validating Button Clicks

You may encounter a situation where you have a button that should only be clickable if certain conditions are met—for example, if slides are available in a carousel. When no slides are present, the button should become disabled, typically indicated by adding a disabled class to the button element.

Consider the following HTML structures:

When Slides Are Available

The challenge is to write a Cypress test that correctly validates this behavior: the button should be clickable when enabled and should not allow any actions when it is disabled.

The Solution: Implementing the Validation Logic

To achieve this functionality in your Cypress tests, you can use the following refined code structure. Instead of using .then(), we'll apply .each() to handle multiple button states.

Step 1: Retrieve the Button Elements

First, we'll use cy.get('.arrow') to retrieve all button elements that match the .arrow class.

Step 2: Validate Each Button

We will iterate through each button using .each() and check if it has the disabled class. Here's how you can implement this logic:

Breakdown of the Code

cy.get('.arrow'): This selects all buttons with the class arrow.

should('be.visible'): Confirmation that the button is visible on the page.

.each(($btn): Iterates through each button element, allowing for individual validation.

hasClass('disabled'): Checks if the button has the disabled class.

cy.wrap($btn): Wraps the raw DOM element to enable Cypress commands on it.

CSS Assertions: Validates the button's visual state based on its enabled/disabled status.

Conclusion

By implementing this structured approach in your Cypress tests, you can ensure that buttons behave as expected based on the availability of slides. This not only improves the functionality of your application but also enhances the overall user experience. With clear visual feedback and robust testing, you can lead users smoothly through your application.
