You agree to abstain from drinking, attend AA meetings three times a week, and submit to random alcohol testing.

So you move away from random testing, you target it through contact tracing or contact warning.

英语百科
Random testing
Random testing is a black-box software testing technique where programs are tested by generating random, independent inputs. Results of the output are compared against software specifications to verify that the test output is pass or fail. In case of absence of specifications the exceptions of the language are used which means if an exception arises during test execution then it means there is a fault in the program.
