How to Compare Text Content of Two Elements in Cypress Testing

In the world of automated testing, particularly when using frameworks like Cypress, ensuring that your web application behaves as expected is crucial. One common scenario developers encounter is the need to compare the text content of two elements after user interactions, such as clicking on a button. In this guide, we will explore how to effectively compare the text of buttons with corresponding chart elements to ensure correct data representation in your application.

The Problem

Imagine you have a web application with five buttons representing different time periods: Day, Week, Month, Year, and Decade. When a user clicks on one of these buttons, the application updates the corresponding value in a chart below. Your goal is to confirm that the text displayed in the chart matches the button clicked. However, you hit a snag with your initial testing code.

The Challenge

You need to check if the text of the second element (like your chart) updates to match the button clicked. Your existing approach involves using Cypress's cy.get() method, but it doesn't seem to yield the desired results. Here’s what your original code looked like:

This code attempts to access the text of the 'Second element' but gets stuck because you can't directly compare the text like that. Let's look at how to restructure this for success.

Step-by-Step Solution

Here’s a rewritten approach that successfully compares the text of the clicked button and the second element (presumably your chart). Follow these steps to implement the solution:

1. Define Your Selectors

First, ensure your array of selectors for the buttons is defined correctly. This will allow your testing framework to locate each button accurately:

2. Use forEach to Click Each Button

Utilize the forEach method to iterate through your button selectors. For each button, you will click and then compare the text:

This snippet clicks each button and retrieves its text (assertionText).

3. Fetch the Text of the Second Element

Next, you will need to grab the text from the second element (the chart). To do this effectively, use the invoke() method to obtain the text value:

This part ensures that you are fetching the current text content from your second element.

4. Compare the Texts

With both texts at hand, you can now perform the comparison. Depending on whether they match, you can execute specific assertions or logic:

Final Code Implementation

Putting it all together, here’s the complete function:

Conclusion

In this post, we tackled the typical scenario of comparing text content between two elements during automated tests using Cypress. By ensuring proper retrieval of text values and restructuring the comparison logic, you can enhance the reliability of your tests. This not only improves the quality of your application but also boosts the confidence in your testing framework.

Using this approach will streamline your testing process and help catch discrepancies between the expected output and the actual displayed result on your web page. Happy testing!
