wow v0 built a whole system to collect testimonials

I am jetlagged and couldn't sleep so check out my experimental E2E testing agent verify a whole purchase flow from a 2 sentence description

this is gonna be huge 🤩

Here's a more complex example

- describe your test
- agent tries to make it happen on your website (50sec)
- writes down steps as playwright script
- future runs replay the script and verify website works (10sec)

I'm excited. This will save so much tedium

81% faster than the first run with full agent mode
on airport wifi, no video speedup 🤘

Alright the e2e testing agent is verging on useful

added a very basic caching layer and now you have the agent outputing a stable test suite that's pretty fast to run (70% faster than 1st run)

I think we can push harder

Ok it's a little slow but this feels like a good way to write e2e tests. Just needs a good caching layer

video sped up 5x

IT WORKED!

The agent can follow a simple instruction and test a workflow \o/

now just gotta keep track of the playwright calls and output a test suite
