[0045] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is merely intended to explain the present application, and is not intended to limit the present application. The present application can be implemented without some of the specific details, which are not required for understanding the present application. The following description of the embodiments is merely provided to give a better understanding of the present application by showing examples of the present application.

[0046] It should be noted that the terms such as first and second, etc., are merely used to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between such entities or operations. Also, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that processes, methods, articles or apparatuses including a series of elements not only include those elements, but also include other elements not explicitly listed, or further include elements inherent in such processes, methods, articles or apparatuses. Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the processes, methods, articles or apparatuses including the elements.

[0047] As described in the background section, the actual server does not necessarily conform to the window size of the client, so this also leads to the possibility of transmission errors between the client and the server.

[0048] To solve the problems in the prior art, the application sends first segmented transmission data in the plurality of segmented transmission data to the server, so that the server sends the expected window size of the server capable of receiving transmission data to the client in the case that the expected window size is smaller than the preset window size, so that the segmented transmission data can be sent to the server according to the expected window size of the server, so that each segmented transmission data can be normally transmitted to the server, the probability of errors in the transmission of the segmented transmission data is reduced, and the accuracy of data transmission is improved.

[0049] Based on this, the application provides a data testing method, a transmission method, equipment, a client and a storage medium. First, the data transmission method provided by the embodiment of the application is introduced.

[0050] Figure 1 A flowchart of the data transmission method provided by an embodiment of the application is shown.

[0051] As shown in Figure 1 , it can include the following steps:

[0052] S101, obtaining transmission data;

[0053] S102, segmenting the transmission data according to the preset window size of the client and the byte length of the transmission data to obtain a plurality of segmented transmission data;

[0054] S103, transmitting first segmented transmission data to the server, so that the server sends the expected window size to the client in the case that the expected window size is smaller than the preset window size, the preset window size corresponds to the client, and the expected window size corresponds to the server;

[0055] S104, transmitting each segmented transmission data to the server in turn according to the expected window size.

[0056] Based on the above embodiment, the application obtains the transmission data, segments the transmission data according to the communication protocol to obtain a plurality of segmented transmission data, and then sends the first segmented transmission data in the plurality of segmented transmission data to the server. Thus, the server sends the expected window size of the server capable of receiving the transmission data to the client in the case that the expected window size is smaller than the preset window size, so that the segmented transmission data can be sent to the server according to the expected window size of the server, and each segmented transmission data can be normally transmitted to the server, thereby reducing the probability of error in the transmission of the segmented transmission data and improving the accuracy of data transmission.

[0057] In S101, the transmission data to be tested is obtained.

[0058] As an example, in order to ensure the test effect, the byte length of the transmission data should be long enough, otherwise the number of segments will be too small, which will affect the test effect.

[0059] In S102, the data is segmented and sent according to the specified format, which can ensure the correctness and compatibility of the data. Therefore, the transmission data needs to be segmented according to the preset window size and the byte length of the transmission data, and more specifically, there is a transmission sequence between each segmented transmission data.

[0060] As an example, the "window size" generally refers to the size or format of the data packet used when the network client communicates with the network server. This size is usually measured in bytes.

[0061] In S103, each segmented transmission data is transmitted to the server one by one. After the first segmented transmission data is transmitted to the server, if the expected window size of the server is smaller than the preset window size of the client, the server cannot receive the first segmented transmission data transmitted by the client, so the server sends the expected window size of the server to the client in the form of a message.

[0062] In S104, after obtaining the expected window size of the server, the client retransmits the first segmented transmission data according to the expected window size until each segmented transmission data is transmitted to the server.

[0063] Specifically, the following method can be used to determine that each segmented transmission data is transmitted to the server.

[0064] The order identifier of the third segmented transmission data is obtained.

[0065] In a case where the sequence identifier of the third segment transmission data is the preset identifier, it is determined that all the segment transmission data are transmitted to the server after the third segment transmission data are transmitted to the server.

[0066] Each segment transmission data is provided with a corresponding sequence identifier, which is used to indicate the transmission sequence of the segment transmission data. As an example, the sequence identifier can be a MOR field in the segment transmission data. If the MOR field is 1, it indicates that there is other segment transmission data to be transmitted after the segment transmission data. If the MOR field is 0, it indicates that there is no other segment transmission data to be transmitted after the segment transmission data. Therefore, if the sequence identifier of the third segment transmission data is the preset identifier, it indicates that all the segment transmission data are transmitted to the server.

[0067] In order to test more data transmission methods, the application further provides another implementation manner of the data transmission method.

[0068] Figure 2 Another flowchart of the data transmission method provided by an embodiment of the application is shown in FIG. 6. Figure 2 As shown in FIG. 6, S104 can further include the following steps.

[0069] S201, respectively determining actual window sizes corresponding to the segment transmission data according to the expected window size.

[0070] S202, sequentially transmitting the segment transmission data to the server according to the actual window sizes.

[0071] Based on the above embodiment, the actual window sizes of the segment transmission data are determined according to the expected window size, so that the segment transmission data are respectively transmitted to the server according to the corresponding actual window sizes. Therefore, the connection between the actual transmission windows of the servers can be tested.

[0072] In S201, the actual window sizes corresponding to the segment transmission data are respectively determined based on the communication protocol, the expected window size of the server, and the arrangement sequence of the segment transmission data.

[0073] Specifically, as an example:

[0074] The actual window size is determined as the difference between the expected window size and a fixed value, the fixed value is increased by 1 in each cycle, and the fixed value is greater than or equal to 1.

[0075] For example, the actual window size of the first segment transmission data can be the expected window size-1; the actual transmission window size of the second segment transmission data can be the expected window size-2, and the actual window size of the third segment transmission data can be the expected window size-3. Wherein, 1, 2, and 3 are: an increasing sequence with a tolerance of 1 and a first term of 1.

[0076] Each segmented transmission data transmission to the server is a cycle.

[0077] Alternatively, the actual window size is determined as the difference between the expected window size and a random value, and the random value is greater than 1.

[0078] The actual window size of the first segmented transmission data can be the expected window size-2; the actual window size of the second segmented transmission data can be the expected window size-3, and the actual window size of the third segmented transmission data can be the expected window size-7; wherein 1, 3 and 7 are random values.

[0079] In addition, in the plurality of segmented transmission data, the actual window size of any segmented transmission data can be the difference between the expected window size and a fixed value, or the difference between the expected window size and a random value.

[0080] It should be noted that, in the embodiment, the second segmented transmission data refers to the segmented transmission data sent to the server after the first segmented transmission data is transmitted to the server, and the third segmented transmission data refers to the segmented transmission data sent to the server after the second segmented transmission data is transmitted to the server.

[0081] In the above S202, after the actual window size corresponding to each segmented transmission data is determined, the server transmits each segmented transmission data to the client according to the actual window size corresponding to each segmented transmission data.

[0082] In other embodiments, when the expected window size is greater than or equal to the preset window size of the client, the actual window size of any segmented transmission data in the transmission process can be the difference between the expected window size and a fixed value, or the difference between the expected window size and a random value.

[0083] In order to test more data transmission methods, the application further provides another implementation manner of the data transmission method.

[0084] Figure 3 Another flowchart of the data transmission method provided by an embodiment of the application is shown, as shown in Figure 3 The above S104 can further include the following steps:

[0085] S301, after the first segmented transmission data is transmitted to the server, a first reply message of the server is received;

[0086] S302, the transmission of the second segmented transmission data to the server is stopped;

[0087] S303, receiving a second reply message replied by the server according to the first segmented transmission data, the second reply message being sent by the server in a case that the second segmented transmission data is not received by the server within a preset time length;

[0088] S304, in a case that the first data identifier in the first reply message is consistent with the second data identifier in the second reply message, determining that the communication state between the server and the client is a normal state.

[0089] Based on the above embodiment, by respectively receiving the first reply message replied by the server after sending the first segmented transmission data; and the second reply message sent by the server after stopping sending the second segmented transmission data, the consistency of the first reply message and the second reply message is compared, so that in a case that the first reply message and the second reply message are consistent, it can be determined that the communication between the client and the server is normal, and the server can normally start the timeout retransmission mechanism in a case that the client does not respond for a long time.

[0090] In the above S301, after the client sends the first segmented transmission data to the server, the server will reply the first reply message to the client according to the first segmented transmission data, so that the client can receive the first reply message replied by the server, and the first reply message is used to tell the client that the server has received the first segmented transmission data.

[0091] In the above S302, when the client uploads each segmented transmission data to the server, the client may not receive a response due to network fluctuation, at this time the server will send a response message (i.e. timeout retransmission mechanism) to the client again. However, the probability of natural network fluctuation during testing is very low, which is difficult to control artificially, so it is difficult to cover the test scene of the timeout retransmission of the server response message. Therefore, in order to test the timeout retransmission mechanism, after sending the first segmented transmission data to the server, the second segmented transmission data needs to be stopped from being sent to the server, so as to simulate the case that there is communication abnormality between the client and the server due to network fluctuation, and the client cannot respond to the first reply message, resulting in the failure to continue sending the second segmented transmission data.

[0092] In the above S303, if the server does not receive the second segmented transmission data within a preset time length, the timeout retransmission mechanism will be triggered, so the server will send the second reply message to the client again, so that the client sends the second segmented transmission data to the server, but the second reply message is not necessarily generated due to the triggering of the timeout retransmission mechanism, but also a reply message for error reporting due to communication error.

[0093] In S304, the first data identifier in the first reply message is compared with the second data identifier in the second reply message. If they are consistent, it is indicated that the first reply message and the second reply message are consistent, and the second reply message is the same as the first reply message, which is a prompt information sent by the server to the client after receiving the first segmented transmission data, and is used to prompt the client to send the second segmented transmission data to the server. Therefore, the second reply message is sent by triggering the timeout retransmission mechanism. Otherwise, the second reply message may not be generated by triggering the timeout retransmission mechanism.

[0094] As an example, the data identifier can include an Invoke ID and a Sequence Number.

[0095] As an example, the data identifier in each reply message is stored in the database of the client.

[0096] After the data transmission method for data transmission test is completed, the data transmission method can be further tested.

[0097] The data transmission test method provided by the embodiment of the application will be introduced below.

[0098] Figure 4 A flowchart of the data transmission test method provided by an embodiment of the application is shown. As shown in the figure, the method can include the following steps: Figure 4

[0099] S401, obtaining an actual data transmission process of the client and the server;

[0100] S402, comparing the actual data transmission process with the data transmission test process of the method, to obtain a test result.

[0101] The actual data transmission between the server and the client can be obtained by using a packet capture tool. The actual data transmission is compared with the data transmission method in any one of the above methods, to obtain a test result. Specifically, whether the data transmission between the server and the client is consistent with the transmission process described in the data transmission method is detected. Figures 1-3 If they are consistent, it is indicated that the data transmission between the server and the client is normal. If they are not consistent, it is indicated that the data transmission between the server and the client is abnormal, and the packet capture file obtained by the packet capture tool needs to be provided to the developer for problem troubleshooting. Therefore, the accuracy and convenience of the data transmission detection are improved.
