The scheduling room is called the scheduling room because it is the component that runs the nine components step by step. The component and the component do not know the other component's existence, but testinvocation knows it. Instead of creating an object through the reflection mechanism, it calls the interface method to get what it wants and then passes it to the next component. The above method shows that it first obtains the buildprovider object. Call the getbuild object to obtain the ibuildinfo object. In our program, we actually call the getbuild method of ctsbuildprovider.

If Info is not null: inject ibuildinfo to the test task to determine whether the task can be split. If not, register the device Recovery class and jump to the performinvocation method.

If Info is null: No executable build is displayed, call irescheduler. reschedulecommand () to retry.

/*** Performs the invocation ** @ Param config * The {@ link iconfiguration} * @ Param device * The {@ link itestdevice} to use. may be <code> null </code> * @ Param info * The {@ link ibuildinfo} */private void implements minvocation (iconfiguration config, itestdevice device, ibuildinfo info, irescheduler rescheduler) throws throwable {Boolean resumed = false; long starttime = system. currenttimemillis (); long Elapsedtime =-1; info. setdeviceserial (device. getserialnumber (); startinvocation (config, device, Info); try {Device. setoptions (config. getdeviceoptions (); // prepare to build and run caseprepareandrun (config, device, info, reschedrun);} catch (builderror e) {clog.

Resumed) {reportfailure (E, config. gettestinvocationlisteners (), config, info, rescheduler);} else {clog. I ("rescheduled failed invocation for resume");} Throw E;} catch (runtimeexception e) {// log a warning here so its captured before reportlogs is calledclog. W ("unexpected exception when running invocation: % s", E. tostring (); reportfailure (E, config. gettestinvocationlisteners (), config, info, resche Dashes); throw E;} catch (assertionerror e) {clog. W ("caught assertionerror while running invocation:", E. tostring (); reportfailure (E, config. gettestinvocationlisteners (), config, info, rescheduler);} finally {mstatus = "done running tests"; try {// reportlogs (device, config. gettestinvocationlisteners (), config. getlogoutput (); elapsedtime = system. currenttimemillis ()-starttime; If (! Resumed) {// send the report invocationsummaryhelper. reportinvocationended (config. gettestinvocationlisteners (), elapsedtime);} finally {config. getbuildprovider (). Cleanup (Info );}}}

Start the start method of all listeners to start a notification.

/** * Starts the invocation. * <p/> * Starts logging, and informs listeners that invocation has been started. *  * @param config * @param device * @param info */private void startInvocation(IConfiguration config, ITestDevice device, IBuildInfo info) {logStartInvocation(info, device);for (ITestInvocationListener listener : config.getTestInvocationListeners()) {try {listener.invocationStarted(info);} catch (RuntimeException e) {// don't let one listener leave the invocation in a bad stateCLog.e("Caught runtime exception from ITestInvocationListener");CLog.e(e);}}}

Then obtain the device_options object and set it to itestdevice. Call the prepareandrun (config, device, info, rescheduler); method.

Private void prepareandrun (iconfiguration config, itestdevice device, ibuildinfo info, irescheduler reschedable) throws throwable {// use the junit3 logic for handling exceptions when running teststhrowable exception = NULL; try {// If (config. getcommandoptions (). isneedprepare ()&&! Isrepeat) {dosetup (config, device, Info); // The isrepeat = true;} else {clog. loganddisplay (loglevel. debug, String. format ("No need to flash, derect to run case");} // run caseruntests (device, info, config, reschedsts);} catch (throwable running) {exception = running;} finally {try {If (config. getcommandoptions (). isneedteardown () {doteardown (config, device, info, exception) ;}} catch (throwable tea Ringdown) {If (exception = NULL) {exception = tearingdown ;}} if (exception! = NULL) {Throw exception ;}}

In this method, first obtain whether prepare is required according to performance_options. If necessary, call the target_prepare class to prepare for the work. If not, call the runtests method directly.

private void runTests(ITestDevice device, IBuildInfo buildInfo, IConfiguration config, IRescheduler rescheduler) throws DeviceNotAvailableException {List<ITestInvocationListener> listeners = config.getTestInvocationListeners();for (IRemoteTest test : config.getTests()) {if (test instanceof IDeviceTest) {((IDeviceTest) test).setDevice(device);}test.run(new ResultForwarder(listeners));}}

The above method calls the class configured by tests to catch up with the run method in the call to start the test. After the test is completed, perform teardown.
