Navigating Button Selection in Cypress Testing

When performing automated tests using Cypress, you might encounter scenarios where you need to interact with multiple elements that share the same selector. This can be particularly tricky when you want to exclude certain elements—like keeping the first item intact—while performing actions like deletions. In this guide, we’ll explore how to selectively click on buttons in a situation where some items need to remain untouched.

The Problem: Deleting Items Selectively

Suppose you have a table with multiple items, and your objective is to perform a delete action on all items except the first one. An initial attempt using the button click command looks like this:

While the above code effectively deletes all items, it fails to meet our requirement of preserving the first item. We need a solution that filters the selection of elements before the delete action is triggered.

The Solution: Slicing the Selected Elements

To ensure that we keep the first item while deleting the rest, we can utilize the .slice() method. This method allows us to select a portion of the elements fetched by our selector. Here’s how you can adjust the code to achieve this:

Steps to Click a Subset of Buttons

Select all items: Begin by fetching all the elements with the desired selector.

Exclude the First Item: Use the .invoke('slice', 1) method to skip the first item and select the rest.

Click on Selected Items: Trigger the click event on the remaining items.

Verify the Remaining Count: Finally, confirm that only one item remains in the selection.

Example Code

Here’s the refined version of the code that accomplishes our goal:

Explanation of Each Step

Fetching Items: cy.get('[data-cy="item"]') collects all elements that match the data-cy attribute you’ve specified.

Slicing the Array: The invoke('slice', 1) command effectively removes the first item from our selection, allowing us to work with just the rest of the elements.

Multiple Clicks: The { multiple: true } option ensures that all selected buttons are clicked simultaneously.

Verification: The last line of code checks that we still have one item left (the first item), maintaining our requirement for selective deletion.

Conclusion

By leveraging the .slice() method alongside other Cypress commands, you can effectively manage and manipulate selections of elements in your tests. This approach not only ensures that essential elements are preserved, but also enhances the reliability of your test automation scripts. Implementing these strategies will help you navigate complex UI testing scenarios with ease, minimizing the risk of erroneous deletions or actions. Happy testing!
