Before moving a browser suite, isolate the cause of failures

A browser framework migration is a product decision as well as an engineering project. It affects fixtures, debugging habits, CI and the work needed to keep coverage useful. It's also easy to start for the wrong reason.

Classify what's failing today

Before comparing tools, go through recent failures in the current suite. If they come from shared accounts, arbitrary waits or unclear expectations, changing the framework may leave the underlying problem intact. You'd pay for the migration and still have the flakiness.

Run a small comparison

Choose a small, representative set of flows. Use equivalent data and assertions in both versions, then:

1. Inspect an intentional failure. How quickly can someone who didn't write the test explain it?
2. Make a harmless UI change. What did each version need?
3. Run both in CI. How long did they take, and what did you have to set up?

Consult the current Cypress documentation and Playwright documentation for the capabilities you actually need. Both have changed a lot, and older comparison posts can mislead.

You might not need to move at all

The same approach applies when you're looking at Zerocheck. Start alongside your existing suite with one described browser flow, ideally one nobody has automated yet. It doesn't convert framework code, and useful component or integration tests should stay where they are.
