Embodiment
In describing below, in order to illustrate rather than in order to limit, it is proposed that such as tool of particular system structure, technology etc
Body details, thoroughly to understand the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specific
The present invention can also be realized in the other embodiments of details.In other situations, omit to well-known system, device, electricity
Road and the detailed description of method, in case unnecessary details hinders description of the invention.
In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
Embodiment one
Referring to Fig. 1, there is provided the data of the embodiment of the present invention send the implementation process schematic diagram of method of testing, are described in detail such as
Under：
Step S101, send equipment by first and obtain character sequence to be sent according to the characteristic of default character string
Row；The first transmission equipment is to be devices under.
In order to test data sendaisle correctness, it is necessary to by send equipment be arranged to be devices under.Acquired
Character string is one group of regular character string as caused by first sends equipment.
It is typically the correctness that sendaisle or receiving channel are verified using random number in the prior art, however, this
One method is needed simultaneously using the sendaisle and receiving channel of equipment to be tested, with the data verified the data received with sent
It is whether consistent.But when data transmission fault, due to using the sendaisle and receiving channel of equipment to be tested simultaneously,
And it is sendaisle or receiving channel produced problem to be difficult to determination.And the present embodiment is then using the character with certain rule
Sequence, then the data of reception need to only be verified in receiving terminal, when data transmission fault, be directly assured that it is to send
Passage produced problem.
Further, send equipment by first and obtain character string to be sent according to the characteristic of default character string
Process be：
Equipment is sent for first and distributes interim internal memory, and the size of the interim internal memory is not less than the maximum of single transmission data
Number of characters M；The value S of the current initial character to be sent of the initialization and character count C1 sent.
Character number L to be sent is determined, is obtained since the initial character S to be sent according to increasing or decreasing mode
The character string to be sent being made up of L character.
Initial character S to be sent is updated, for obtaining next section of character string.
It is readily appreciated that, in order to meet that single sends transmitted max number of characters, it is necessary to be first in whole test
Send equipment and distribute enough internal memory M.For example, it is 10240 bytes that single, which sends the max number of characters for needing to test, then distribute
The datarams of 10240 bytes can meet to require.Need first to open and configured PORT COM before transmitting data, make
Operation must be sent can be with normal operation.Here we open and configured communication terminal by the api function of calling system offer
Mouthful.Communicate malfunction when, for the ease of being united to the byte position of error, expected right value and total number of characters for having received
Meter is, it is necessary to which initial character to be sent and the character count sent are zeroed out.
For the ease of being counted to received character number, it is necessary to first determine character number L to be sent, here
Character number can be an a range of random number or a fixed-length value set in advance, can be with
It is the length value of a progressive change., can be with for example, character to be sent can be the fixed value that length is all 1 or 5 every time
It is that each data length value is the character string incremented by successively of the data lengths such as 3,5,7,9.
After character number to be sent is determined, according to default generation character since initial character S to be sent
Form generation character string, and the character string of generation is distributed into the internal memory of the first equipment.For example, work as default data
Sample be circulation increasing sequence, then incrementally produce data, when default data sample be circulation descending series, then with
The mode successively decreased produces data., wherein it is desired to the shape of the generation data of the increasing or decreasing of data sample is preset before testing
Formula.
, it is necessary to update the value of initial character to be sent after one section of character string is sent, to be used to obtain next section
Character string.Specifically, character string is produced by the way of incremental using circulation, then the lead-in identifier value after updating is needed than this
The value more 1 of last byte of data is sent, when last byte value is 255, then the lead-in identifier value after updating is 0.
Similarly, character string is produced by the way of successively decreasing using circulation, then the lead-in identifier value after updating is needed than this transmission data
Last byte value few 1, when last byte value is 0, then the lead-in identifier value after updating is 255.
Step S102, the character string is sent to the first receiving device, and, send next section to the first receiving device
Character string.
Further, it is to the process of the first receiving device transmission character string：
The correlation function that calling system provides, persistently detect whether sendaisle there are enough transmission buffering areas.
When detecting that sendaisle has the transmission buffering area not less than L byte, the transmission letter of calling system offer
Number, sends the character string to be sent being made up of L character of the acquisition, and data length L is added into what is sent
In character count C1.
It is readily appreciated that, needs first to detect whether sendaisle there are enough transmission bufferings before data to be tested are sent
Area is, it is necessary to could send data to be sent in the case where there is enough buffering areas.Here enough transmissions buffering
Area refers to the single data length L to be sent.
Step S103, the described first character string for sending equipment and sending is received by first receiving device；
First receiving device is testing service equipment trusty.
In order to test the correctness of sendaisle, it is necessary to set a receiving device to receive and verify that sending equipment is sent out
The data sent, receiving device herein is testing service equipment trusty.
Further, it is in the process of the character string of reception the first transmission equipment transmission：
Interim internal memory is distributed for the first receiving device, the size of the interim internal memory receives the maximum of data not less than single
Number of characters N；The value R of the current initial character to be received of the initialization and character count C2 received.
The detection function that calling system provides, persistently check whether receiving channel has the arrival of data.
When detecting that receiving channel has data arrival, the correlation reception function of calling system offer, described first is received
Send the character string being made up of L character that equipment is sent.
The character string received is stored in order caching, and data length L is added to the character meter received
In number C2.
It is readily appreciated that, in order to meet that single receives transmitted max number of characters, it is necessary to be first in whole test
Receiving device distributes enough internal memory N.The selection of maximum memory needs to ensure that receiving data terminal will not occur to receive overflowing for data
Go out.It is also required to open and configured PORT COM before receiving the data.For the ease of statistics communication error when byte position and
The total number of characters received is, it is necessary to which the value R of current initial character to be received and the counting C2 for having been received by character are zeroed out.
Before character string is received, first check whether receiving channel has the arrival of data, wherein, carried by calling system
The detection function of confession detects whether receiving channel has the arrival of data.In the case where detecting that data arrive, calling system
The receiver function of offer, to receive the L character string for sending equipment and sending.While in order to count of received character
Number is, it is necessary to the character length received every time is added in the character count C2 received.
Step S104, the character string of the reception is verified according to the characteristic of the default character string.
Further, the process verified according to the characteristic of default character string to the character string of the reception
For：
When default character string is circulation increasing sequence, the character string of the reception is incrementally contrasted；
When default character string is circulation descending series, the character string of the reception is contrasted in a manner of successively decreasing.
Initial character R to be received is updated, for the character string received to be compared next time.
Specifically, it is necessary to which the byte-by-byte character string to reception is entered during the data to receiving are verified
Row compares.It is compared according to the characteristic of default character string, it is necessary to update waiting after the completion of one section of character string compares
The initial character of receipts, specifically, character string is produced by the way of incremental using circulation, then the lead-in identifier value after updating is needed than this
The value more 1 of secondary last byte for sending data, when last byte value is 255, then the lead-in identifier value after updating is
0.Similarly, character string is produced by the way of successively decreasing using circulation, then the lead-in identifier value after updating is needed than this transmission number
According to last byte value few 1, when last byte value is 0, then the lead-in identifier value after updating is 255.
Step S105, if the content of certain byte of the reception and default data are inconsistent, pause receives described the
One sends the character string transmitted by equipment, and reports that described first sends equipment error.
When occurring expected character value and inconsistent actual characters value in comparison process, numeral 1 is returned, represents that comparison is obstructed
Cross.Need to suspend when comparing and occurring wrong and receive transmitted character string, and report error.Meanwhile report the interior of error
Appearance includes：The position of the value of the wrong data byte received, expected right value and wrong data byte, in addition, also including：
Content of all data for receive the sum of character untill current, being currently received etc..
