What are some useful Cypress plugins for visual testing?

Cypress has several plugins for visual testing, such as 'cypress-image-snapshot' and 'cypress-plugin-visual-regression'. These help in comparing screenshots and ensuring UI consistency.

How do I install the 'cypress-image-snapshot' plugin?

You can install it using npm with the command: npm install --save-dev cypress-image-snapshot. After that, you need to add it to your Cypress support file.

Can you explain how to use the plugin in my tests?

Sure! After installing, you can use it in your tests by calling cy.matchImageSnapshot() after taking a screenshot with cy.screenshot(). This will compare the current screenshot with the baseline.

What should I do if the visual test fails?

If a visual test fails, you can review the differences in the screenshots. If the changes are intentional, you can update the baseline image using cy.matchImageSnapshot({ update: true }).
