I've used eBay, Aliexpress and native TaoBao directly. About the only difference is their current market cap. They are so alike in user interaction and session flow one could probably reuse 80% of test cases unmodified.

Wechat is great but here (Norway) payments have been a solved problem for years. I'm not even sure I used cash this year at all other than to unlock a luggage trolley at the airport and it's been like that for over a decade. Even the bank card transaction is so smooth, fast (seconds) and ubiquitous that mobile payment services like Vipps struggled to get a foothold.
