According to an embodiment of the invention, before step S210, the test script of propelling movement can be received.In the step S220 of the first thread implementation of test cases, implementation of test cases can be carried out by calling this test script, test script end of run and test case perform end, the second Thread Termination, now send termination signal to the second thread, this termination signal indicates end, second Thread Termination of test case.According to a kind of embodiment, test script obtains according to test case usually, and will follow " the separable independent operating of step " principle.
Then the second thread in step s 250, detect test case in the first thread whether still performing, wherein step S250 can comprise, detect the termination signal whether received from the first thread, if, then determine that in the first thread, test case performs end, otherwise determine that in the first thread, test case is still in execution.
According to an embodiment of the invention, if determine, in the first thread, test case performs end, then can stop internal memory monitoring, and stop the second thread.
If determine, in the first thread, test case still in execution, then gathers the EMS memory occupation data of tested application in step S260.Particularly, tested application can be selected, and gather the EMS memory occupation data of this tested application from the internal memory monitoring data that above-mentioned mobile terminal 100 obtains.
After obtaining these EMS memory occupation data, in step S270, can judge whether tested application memory overflow occurs according to these EMS memory occupation data.Particularly, according to an embodiment of the invention, can judge whether these EMS memory occupation data are greater than maximum memory alarm value, if so, then determine tested application generation memory overflow; Or calculate EMS memory occupation growth rate according to EMS memory occupation data, judge whether EMS memory occupation growth rate is greater than internal memory growth rate alarm value, if so, then determine tested application generation memory overflow.If be no both above, then determine that tested application memory overflow does not occur.Wherein by when after the EMS memory occupation data once gathered before time EMS memory occupation data of collection deduct, EMS memory occupation growth rate can be obtained divided by sampling time interval.
According to an embodiment of the invention, maximum memory alarm value can be 50MB, and internal memory growth rate alarm value can be 10KB/s.
If judge not there is memory overflow in tested application, then every sampling time interval, repeat above-mentioned steps S250, S260 and S270, till judging tested application generation memory overflow.
When judging tested application generation memory overflow, the second thread gives the alarm signal in step S280, and in step S290, extracts the memory information file of this tested application simultaneously, so that according to the memory leakage position of the tested application of this memory information document alignment.Particularly, by the PID of tested application, and kill-10PID order can be used, extract the memory information file of this application.After using this order, generally will equipment /data/misc catalogue under generate hprof file, hprof file comprises the memory usage information of this tested application, by MAT tool to open, can analyze concrete Memory Allocation situation.
Like this, can judge whether more accurately memory overflow occurs by EMS memory occupation data and internal memory growth rate, and can notify that tester pays close attention to the very first time when there is memory overflow, need not connect PC can obtain the file preserving complete memory information simultaneously, the concrete position that RAM leakage occurs can be located more accurately by this file tester, avoid because of internal memory be released after the memory information that causes complete, be difficult to the situation of locating.
