How to Retrieve Elements in Cypress by the Last Word in its Attribute

When working with automated testing in Cypress, you may encounter situations where you need to locate elements based on specific patterns in their attributes. For instance, you might have a div element with the following ID: random_is_good and want to retrieve it by focusing on the last part of its identifier (_is_good) or even using just the beginning and ending portions (random_ and _good). In this guide, we will explore how to effectively accomplish this using different selectors in Cypress.

Understanding Element Selectors in Cypress

Cypress provides a few powerful ways to select elements based on attribute values using a variety of operators. Here, we'll break down the specific operators you need to master.

1. Using the Partial Text Match Operator *=

If you want to match elements that contain certain text anywhere in their attribute, the *= operator is your best friend. In our case:

To select any div whose ID includes _is_good, you would write:

This command tells Cypress to grab any div elements where the ID contains the substring _is_good, allowing for flexible matching.

2. Using the Starts With Operator ^=

If you know the starting part of the attribute value, you can use the ^= operator. For example, to select a div that starts with random_, the command would look like this:

Start a search for elements whose IDs begin with random_:

This is particularly useful when you would rather match based on the beginning of an attribute rather than the entire value, or just a segment of it.

3. Using the Ends With Operator $=

Conversely, if your focus is on the end of the attribute value, you can utilize the $= operator. For example:

To select a div whose ID ends with _good, you’ll use:

This method is excellent for cases where you only want to ensure that the ID concludes with a particular suffix, offering yet another layer of flexibility in your tests.

Combining Selectors for Greater Precision

Sometimes, you may need to combine these selectors for a more precise match. By mixing and matching the *= (contains), ^= (starts with), and $= (ends with) operators, you can create very exact queries to retrieve the needed elements. For example, if you want to ensure that an ID starts with random_ and also ends with _good, you can chain the commands logically.

Conclusion

Utilizing these selectors in Cypress allows you to become highly efficient in your automated test scripts. Whether you need to match partial strings or focus on particular segments of an attribute, the ability to get elements by the last word in their ID or any other pattern helps streamline your testing process. With practice, you’ll be able to apply these techniques effectively and confidently in your Cypress projects.

So, the next time you find yourself needing to pick apart a complex identifier, remember these operators and how they can simplify your work! Happy testing!
