Redis Building redis release version 7.2.1 and then try to run make test failed on Testing unit/oom-score-adj

I didn't have any error when building binary file and launch redis-server seems ok. OS version: Ubuntu 18.04 make test output is as below:

[exception]: Executing test client: ERR CONFIG SET failed (possibly related to argument 'oom-score-adj') - Failed to set current oom_score_adj. Check server logs..
ERR CONFIG SET failed (possibly related to argument 'oom-score-adj') - Failed to set current oom_score_adj. Check server logs.

that's possibly due to insufficient permissions or something. you can try running ./runtest --single unit/oom-score-adj --dump-logs to get more info
