PASS tID1 > 0 is true
PASS tID2 > 0 is true
PASS tID3 > 0 is true
PASS tID1 !== tID2 is true
PASS tID1 !== tID3 is true
PASS tID2 !== tID3 is true


Checking the results of setInterval:
PASS iID1 > 0 is true
PASS iID2 > 0 is true
PASS iID3 > 0 is true
PASS iID1 !== iID2 is true
PASS iID1 !== iID3 is true
PASS iID2 !== iID3 is true
