Description of drawings
Fig. 1 is the concrete flow chart of implementing of the present invention.
Embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
Adopt this invention, the upper computer software of tester generally is made up of test module and support programs, and test module is finished the function relevant with test service, and support programs are then finished auxiliary function, as interface display, data access etc.
Usually, upper computer software is initiated test command, but actual test is finished by slave computer and measurand.Slave computer is special test hardware device or the test instrumentation with disposal ability, can cooperatively interact with measurand and finish real test.When carrying out concurrent testing, the support of slave computer resource is tested some measurands simultaneously.
In the test of cdma base station clock veneer, slave computer carries out communication by unique serial ports and host computer, accepts the test command that host computer issues and tests, or the query statement that issues is answered; Simultaneously, slave computer and each tested single board are formed the actual subsystem of testing together, and they can be tested simultaneously.
Concrete step is as follows:
One, the testing process of measurand is divided into a series of test items of front and back ordinal relation
According to the test characteristic and the method for measurand, at first the testing process with measurand is divided into a plurality of test items.
As method of testing and characteristic according to cdma base station clock veneer, be divided into testing process relatively independent and have the test item of a graded, comprise test items such as program download, Automatic parameter setting, TOD state verification, the concrete test process of these test items is realized by the function in the test dynamic link library file.
Most of test processs of these test items all are to issue test command by host computer to give slave computer, slave computer begins test and responds to host computer, whether host computer transmitting order to lower levels inquiry test is frequently finished then, slave computer then returns to host computer with current test case, inquires till test finished and obtain test result up to the host computer transmitting order to lower levels.
Finishing of these test items is not to finish in test once, and as the TOD state verification, whole test process needs 30 minutes, all is that a plurality of timeslices in the wheel current test are finished.
Two, with host computer processing time burst, in a timeslice, host computer only carries out communication with a slave computer, finishes all slave computer communications successively, and so circulation is finished until all measurand tests.
In the test process of described step 2, timesharing is to realize in upper computer software, the timeslice dynamic assignment, and the length of each timeslice can be indefinite.Concrete steps are as follows:
1, beginning current time sheet obtains current measurand, and reads current test item to be measured;
2, carry out the current test item of current measurand;
3, after current test item returns, preserve the test item data, finish the current time sheet;
4, jump to next measurand, distribute new timeslice to test, change step 1 over to, all finish, then jump out the wheel current test as all test items of all measurands.
Above-mentioned steps does not also require the test of synchronously all measurands, and each measurand test item is independently; Permission adds new measurand at any time in test process, enter the wheel current test; Each timeslice can be carried out a test item of a measurand, but a test item might be tested in a plurality of timeslices in front and back.
When the user begins to test, in upper computer software, create and independently test thread.No matter it is individual how many measurands has, all only use same test thread to test.After the test thread starts,, create or the refresh test object data according to the actual measurand information that tester obtains.Upper computer software is that each tested object creates a software data structure, has comprised the information such as ID, test position, current test item of measurand.These tested object data will be comprised in certain container, as array, chained list etc., so that at the test subsequent process, utilize container to locate and handle the measurand of appointment fast.
Clock single board test apparatus as cdma base station, in upper computer software, created a class for veneer and association attributes thereof, defined members such as tested single board test trough number, current step ID, and created such object for each actual veneer to be measured, these objects are preserved with the chain sheet form.
After the test beginning, all test items to all measurands are taken turns current test according to certain order, the time of carrying out one of them test item in the measurand is called timeslice, the time size of each timeslice is indefinite, by the definition decision of the test function of test item, whole test process is made up of timeslice.
In each timeslice, at first from the container of preserving measurand, find current measurand, the test position in this object data has been indicated actual measurand, obtains current test item information again from object data; According to current test item information, call the function of realizing test item, carry out actual test, after function returns, current test result is kept in the tested object data, the current time sheet finishes.In next timeslice and then, in container, find next measurand, repeat above-mentioned test.Each test item of each measurand is all had an opportunity to obtain timeslice and is tested.
The moment that is about to begin in the new time, upper computer software can at first be checked the next measurand that is kept in the container, confirm whether it has finished the test of all test items,, then directly skip this object next object is operated as finishing.All finish as all measurands, then finish whole test.
As in cdma base station clock single-board testing, suppose to test simultaneously the polylith veneer, then the tested object chained list has comprised corresponding a plurality of tested objects.
When the test beginning, upper computer software obtains current testing single-board successively from chained list, whether the test sign of checking this veneer is that all test is finished, as unfinished, then read the test item data current to be measured of veneer,, call the function in the corresponding dynamic link library file according to test item dynamic link library file name in the data and test item function name thereof, function is kept at test result in the testing process after carrying out and returning.
The test item function definition the concrete test process of a test item, general, finish a test item and only need carry out linear function, but in some cases, need in a plurality of timeslices that separate front and back, repeatedly carry out function and just can.In realization, have three types during each test item function returns, be respectively test successfully, test crash or hang-up.Test successfully or when failing when function returns, illustrate that this test item finishes, not only will preserve test result, also will define, find next test item information and be made as current test item, treat that the next timeslice that this veneer obtains carries out according to test item; When function returns test and hangs up, illustrate that this test item do not finish as yet, still preserve current test item information, treat that the next timeslice that this veneer obtains carries out.
As TOD state verification function, this function will comprise host computer and send the order whether the inquiry test is finished, and wait and analyze the result that slave computer returns, as return slave computer and tested and finish, then this function returns test success or test crash, as return slave computer still in test, then this function returns the test hang-up.So, in nearly time half an hour of test TOD state verification, though the TOD state of this tested single board is tested in a plurality of timeslices, repeatedly called this function, but except last acquisition result's timeslice, this function all returns the test hang-up under other situations, after function returns the test hang-up, illustrate this test item as yet test finish, need to distribute the follow-up time sheet to continue this test item is tested.After the current time sheet finishes, from the test chained list, obtain next veneer, carry out above-mentioned test.
Begin in each new timeslice, whether upper computer software can be inquired about current tested single board and test and finish, as finishing, then jump to next veneer in the chained list (as current single board in the chained list end position, think that then next veneer is in the chained list original position), continue to judge and test, finish until all clock single-board testings.
Three, EOT quits a program
All tested and finished when upper computer software inquires all measurands, then withdrawed from the circulation of wheel current test, and withdraw from test program, finished whole test process.
In above-mentioned test implementation procedure, can see in test and carrying out in the process, can add new measurand at any time.As in cdma base station clock single-board testing, add new veneer, then in the upper computer software chained list, add new testing single-board data, also just added the process of wheel current test.And, since the test mode of each veneer all by tested object data corresponding in the chained list record, so the testing progress of each veneer can be asynchronous.
The actual test of the measurand test of such scheme is finished jointly by slave computer and measurand, they itself have the characteristic of concurrent testing, though test process needs the intervention of host computer, but the characteristics of have in each measurand upper and lower computer communication process that the communication number of times is few, the time is short, and whole test process host computer free time is longer.So the characteristics of the essence of scheme is to make full use of host computer when testing single measurand a large amount of free times become it into a plurality of measurands of the host computer timesharing testing scheme that communication is carried out in test to slave computer in turn.Adopt this method, utilize time-sharing characteristic, the free time of originally testing an object is used for other a plurality of object tests, make testing efficiency than the obvious raising of conventional method.
Above-described is a production test specific embodiment that uses time sharing test approach to realize a plurality of measurands.Should be noted that this embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under the enlightenment of the method for the invention; do not breaking away under the scope situation that aim of the present invention and claim protect; can also make a lot of distortion, these all belong within the protection of the present invention.
