How to tell OBS to wait longer for test before killing it?

Hello, I try to build CheMPS2. https://build.opensuse.org/package/show/home:andythe_great/CheMPS2 But the test took too long that OBS kill it first. Which it just have to wait a bit longer. Job seems to be stuck here, killed. (after 5400 seconds of inactivity) How to make OBS wait longer? Kind regards, Andy
