9. HOW TO BECOME A WEB DEVELOPER

10. CYPRESS VS SELENIUM

11. CYPRESS VS SELENIUM
„Quick Preview

12. WHY CYPRESS IO
„It’s a new and shiny thing
„You can write tests on JavaScript
„It’s faster than Selenium
„You have Time Travel, videos and
screenshots

13. WHY CYPRESS IO
„Built-in “waits”
„All the needed Requests, Mocks and
Asserts are available out of a box
„You can write asynchronous code
synchronously

14. SELENIUM VS CYPRESS
„Selenium Pros:
Can be used with any programming
language
Supports different browsers
Can switch tabs
Can be ran in parallel

15. SPEED

16. SELENIUM VS CYPRESS
„Should be Super Fast
It doesn’t use HTTP requests like Selenium

17. SELENIUM VS CYPRESS
„How much time would it take
Selenium to enter email, password
and press Submit?

18. SELENIUM VS CYPRESS
„How much time would it take Selenium to
enter email, password and press Submit?

19. SELENIUM VS CYPRESS
„What about Cypress?

20. SELENIUM VS CYPRESS
„What about Cypress?

21. SELENIUM VS CYPRESS
„Cypress 786ms VS Selenium 386ms
„Cypress turned out to be 2 times
slower in action

22. SELENIUM VS CYPRESS
„This is the price you pay for Time Travel,
snapshots, screenshots, video, etc.
„In production it can be faster, because
you have all the requests, direct access to
Local Storage and JS

23. WAITS

24. SELENIUM VS CYPRESS
„Has all the waits (Actionability) ready from
the box

25. SELENIUM VS CYPRESS
„How many waits do we need to
write, before we can click an
element in Selenium?

26. SELENIUM VS CYPRESS
„How many waits do we need to write, before we
can click the element in Selenium?
Wait for element to be present in DOM
Wait for element to be in view
Wait for element to have size bigger then 0
Wait for element not be covered by other
element
…..

27. SELENIUM VS CYPRESS
„What waits do we have in Cypress?

28. SELENIUM VS CYPRESS
„What waits do we have in Cypress?

29. SELENIUM VS CYPRESS
„Everything that we used to have to write
manually in Selenium we now have in
Cypress?

30. SETUP

31. https://www.cypress.io/how-it-works/

32. CYPRESS HOW TO
„Easy to install and setup:
>npm install cypress --save-dev
>cypress open/run

33. CYPRESS HOW TO
„Easy to install and setup
https://docs.cypress.io/guides/getting-started/writing-your-first-test.html

34. CYPRESS HOW TO
„Write asynchronous code
synchronously

35. CYPRESS HOW TO
„Write asynchronous
code synchronously

36. CYPRESS DRAWBACKS

37. CYPRESS DRAWBACKS
„Modules are overridden

38. CYPRESS DRAWBACKS
„Modules are overridden

39. CYPRESS DRAWBACKS
„Modules are overridden
How to deal with it?

40. CYPRESS DRAWBACKS
„It doesn’t support cross-browser testing

41. CYPRESS DRAWBACKS
„It doesn’t support cross-browser testing
It is going to be released soon. It’s one of
the main priorities for the Cypress team

42. CYPRESS DRAWBACKS
„It can’t switch windows.

43. CYPRESS DRAWBACKS
„It can’t switch windows.
So if you need to test something in few
windows it’s better to choose other tool
