Option
room of testApp
Where the code of the app runs in the test.
Value
'apart' runs it in the test room, a thread of its own with 512 MB, which crosses every call as a room apart does. 'program' runs it in the program of the test. Left out, the room of the program, unless the run states TENT_ROOM=apart, which testApp alone reads, and which tent test --room apart states for a whole run.
Example
TypeScript
const app = await testApp({ room: 'apart' })
