One e2e framework to rule them all
CodeceptJS is the only #e2e testing framework that can run same test accross different browser engines:
- @playwrightweb
- @webdriverio
- @lightpanda_io
- Moli
- Obscura
Even we live in 'coding solved' era I still feel that developer need to spend like 2-3 nights walking around the problem before actually doing the implementation
Let's go through lightweight browser engines that you can use today to speed up your testing and development
I tried all them and I would like to share my experience
Save this list of agentic browsers. You will need it one day!
And let's go:
Because of limited features support they use simulated browser events. I.e. initiated by JavaScript and not by real user event. They can send clicks to invisible elements and can't click by coordinates.
Even engines with rendering (Obscura, Molly) are not render perfectly
That's a wrap!
I will write more on agentic testing
Also the good part that all these 3 engines are availble in @CodeceptJS e2e testing framework, among with @playwrightweb and @webdriverio so you can run same test in different engines to find a perfect match!
How can you speed up your Playwright end2end tests?
Well, use one of alternative browsers that can run x3 fast with no chrome under hood
If you use @CodeceptJS you have plenty of options like choosing @lightpanda_io for some e2e tests, making them as fast as possible!
The good thing is that with CodeceptJS it is only one config switch to make tests running in Playwright to run in Lightpanda
No codechange required!

End2end test consists of these AAA steps:
Arrange
Act
Assert
Which of these steps should be scripted and which can be delegated to AI?
That's why bringing Jev-style AI decisions into e2e tests as assertions seems like a good idea:
I.decide(['navigation menu is shown',
'user has a logged in',
'user has ui to create new project',
'user sees list of existing proects']
)
As they are taken as one AI call
And this is how new Decision helper in @CodeceptJS work!
Enable it, connect Jev, and write expressive assertions. Fail when Jev is unconfident. The price of Jev calls are is comparable to price of running clould browser.
