Due to a ransomware attack, the wiki was reverted to a July 2022 version. . We apologize for the lack of a more recent valid backup.
Although CHOTestMonkey still runs based on test cases, we don't explicitly specify pass/fail criteria for each test case, but catch abnormal conditions of ONOS by injecting various checking into each test case.
Sample test case sequence:
0,1,2,3,[10,30,21,31,10,32,21,33,50,10,30,21,31,10,32,21,33,51,40,60,10,30,21,31,10,32,21,33,50,10,30,21,31,10,32,21,33,51,41,60]*500,100
