The system also identifies trace logs associated with each test case, and maps each test case to one or more functions based on the association of the trace logs with each test case. ## Claims ### Claim 1 A method comprising: executing, by a processor, a plurality of test cases against a code that includes a plurality of functions, wherein the executing of the test cases against the code is performed at least twice generating trace logs, wherein each of the executing of the test cases is performed a first time using a first trace switch value and a second time using a second trace switch value, and wherein the first trace switch value is different from the second trace switch value, wherein the executing of the test cases the first time is associated with a first set of functions, wherein the executing of the test cases the second time is associated with a second set of functions, and wherein the first set of functions is different than the second set of functions; identifying the trace logs associated with each of the executing of the test cases; generating a mapping of each test case of the test cases to at least one function of the plurality of functions based on association of the trace logs with each test case by randomly sampling the trace logs;
