Everyone knows that Test Automation is important but...

"We don't have time to write UI tests"

"Writing automated tests slows us down"

"We have a tight deadline so we need to release ASAP"

"I don't know how to use Selenium"

"I have a lot of tickets to test manually"

"Tests are so flaky"

"How do you debug it?"

"Setup is difficult"

"Let's leave it to the SDETs. It's their job"

"I don't understand the error messages"

Modern Web Testing with Cypress

By Marie Drake

Modern Web Testing with Cypress

The web has evolved. Finally, testing has too. This is what you see when you visit Cypress' landing page. In this talk, I would like to share what Cypress is, what its different features are and how it's bridging the gap between developers and testers.
