Abstract

The present invention relates to a multithread test method in a communication equipment tester. The present invention adopts a preemptive mode to allocate the right of use of kernel resources; simultaneously, when the kernel resources are taken up by one thread, the other threads can carry out port activation or test state switchover. Due to the adoption of the preemptive multithread mode, test ports are allocated around the kernel resources, and unreasonable allocation caused by needing artificially setting the order of the test ports can not occur. Thus, the kernel resources in test equipment can be allocated sufficiently and reasonably, and all the port test state switchover and activation operation before service test are both completed at the time of waiting for the kernel resources. The present invention really fully utilizes the kernel resources, and the test efficiency can achieve the maximum value.

Description

Multithread testing method in a kind of tester for communication devices

Technical field

The present invention relates to a kind of method of testing, be specifically related to a kind of multithread testing method that is used for tester for communication devices.

Prior art

In many tests of the communications field, the ADSL test is wherein common and important a kind of production test solution, and this test needs test in two sub-sections: performance test (operational trials) and LAYER1 test (veneer index test).Wherein, main core resource is generally SmartBits (or Ixia) and PSM selects flat level meter in the test process, is respectively applied for two parts of test service and layer1.

These two resource modules belong to the resource of comparison core in a whole set of testing equipment, also be comparison expensive resources module.For the consideration of cost and service efficiency, generally in single testing equipment, only dispose one respectively.

In test process, no matter be that operational trials or LAYER1 test all must be done the port status conversion earlier before test, even tested port is in test mode.In addition, also must be before the operational trials with port activation; Then must arrive the test mode of response by the port switching state before the LAYER1 test.Comparatively speaking, the activation port before the operational trials is more consuming time, and the frequency test among the LAYER1 is more consuming time.

In the prior art, tested single board generally has 16 to 32 road ports not wait, and can reach 64 road ports at most.Existing method of testing has two kinds substantially: serial test and part parallel test.

For the serial test, because when port of test, other ports can not utilize other utilizable resources, thus there is resource utilization low, the shortcoming that testing efficiency is low.

For concurrent testing, its part parallel in test process has utilized core resource, but must activate before the concurrent testing middle port carrying out operational trials, if it is bad to activate characteristic, consuming time longer, will cause phenomenons to be tested such as all resources, caused the wasting of resources to a certain extent.In addition, this method need artificially be provided with the test port order in design early stage, needs the situation consuming time in the consideration test process, if it is not high to dispatch the unreasonable testing efficiency that will cause.

Summary of the invention

The object of the invention can make full use of core resource and the high multithread testing method that is used for tester for communication devices of testing efficiency for providing a kind of.

To achieve these goals, the technical scheme taked of the present invention is:

A kind of tester for communication devices multithread testing method that is used for, it may further comprise the steps:

(1) starts a plurality of test threads, for each core resource is distributed system's mutex;

(2) respectively test thread synchronization contention system mutex, the test thread that obtains system's mutex obtains the right to use of core resource, and the test thread waits that does not obtain system's mutex participates in synchronous contention system mutex next time;

(3) use core resource to test to the test thread of system's mutex, delivery system mutex immediately after test is finished;

(4) judge whether to also have the not test thread of test,, change step (two) over to,, then finish test if do not have if having.

Described step (one) may further comprise the steps:

(1) according to the core resource number, statement system resource;

(2) discharge all system resource, so that the test thread is fought for resource.

Synchronous contention system mutex in the described step (two) specifically comprises the steps:

A, test thread contention system core resource;

When B, mutual exclusion test, the stand-by period can be set to unlimited wait;

The test thread of C, competitive resource is waited for always, up to obtaining system resource.

The test thread of the synchronous contention system mutex in the described step (two) is meant and switches to the test thread that test mode or port are activated.

When described step (three) is carried out, do not switch to the test thread that test mode or port be not activated and to switch to test mode simultaneously or activate port.

Because the present invention has adopted technique scheme, so have following advantage:

1, owing to used the preemptive type multithreading, carries out the test port scheduling, avoided causing dispatching irrational situation appearance because of needs artificially are provided with the test port order around core resource;

2, the core resource in the abundant rational management testing equipment of energy, and all port test state switched and operational trials before activation manipulation all in the time of wait core resource, finish, really make full use of core resource, greatly improved testing efficiency.

Description of drawings

Fig. 1 is the overall flow figure of the specific embodiment of the invention.

Embodiment:

As shown in Figure 1, multithread testing method in a kind of tester for communication devices may further comprise the steps:

(1) starts a plurality of test threads, for each core resource is distributed a Windows system mutex (MUTEX); That is:

1, according to the core resource number, statement system resource Cmutex m_Mutex[n]:

2, discharge all system resource, so that the test thread is fought for resource m_Mutex.Release ();

(2) respectively test and switched to the test thread synchronization contention system mutex that test mode or port are activated in the thread, the test thread that obtains system's mutex obtains the right to use of core resource, the test thread waits that does not obtain system's mutex participates in synchronous contention system mutex next time, does not switch to the test thread that test mode or port be not activated and can switch to test mode simultaneously or activate port; The contention system mutex specifically comprises the steps: synchronously

A, test thread contention system core resource m, occupation mode:

WaitForSingleObject(m_Mutex[m]，WAITTIME)；

When B, mutual exclusion test, stand-by period WAITTIME can be set to unlimited wait, promptly can be set to INFINITE;

The test thread of C, competitive resource is waited for always, up to obtaining system resource m_Mutex[m], this moment, expression obtained corresponding core resource m.

(3) the test thread of system's mutex uses core resource to test, delivery system mutex immediately after test is finished;

Whether (four) disconnected also have the test thread of not testing, if having, changes step (two) over to, if do not have, then finishes test.

Because whole test process is launched around core resource, system start-up a plurality of test threads, in actual mechanical process, be that each core resource distributes system's mutex, the thread that has only obtained this mutex can obtain resource, needs to discharge this mutex after test is finished.Do not obtain the port of test core resource, before obtaining core resource, can earlier state be switched to test mode, in the test service test process, it is preceding to obtain operational trials core resource (SmartBits/IXIA), can activate port earlier, go competition to obtain core resource again after finishing activation, so just state can be switched and port activation operates in other ports and uses in the process that core resources test executed in parallel to finish, see on the whole, our handover operation and activation manipulation are equal to nothing the consumption systems testing time, system test time has utilized core resource to greatest extent by the testing time decision of core resource, has improved testing efficiency.
