Example
Hey, did you hear the new patch is already live on the PTR?
Yeah! I jumped on last night to try out the new class changes. They totally reworked the Druid’s talents
No way—were there a lot of bugs?
A few, but that’s the whole point of the PTR. Better to catch them now than after launch
True. I might hop on tonight. I want to get a feel for the new raid before it hits live servers

PTR is a term used primarily in the gaming world, especially by World of Warcraft (WoW) players to describe servers that are special versions of a game where developers release upcoming content, patches, or balance changes before they go live. Gamers can log in to a PTR to test new features, provide feedback, and help spot bugs.
Game developers and hardcore fans often use PTRs to fine-tune gameplay and squash bugs early. For this reason, PTRs are common in large online games that evolve over time, like MMOs or competitive shooters.
Origin of PTR
Blizzard Entertainment, the developer of WoW, popularized the term in the mid-2000s when they launched PTR servers to improve the quality of major updates before rolling them out to everyone. While WoW helped cement the term, it's now used in other titles like Overwatch, Diablo, and League of Legends (LoL).
