the flow of the test method is described below with reference to fig. 1:

step 101: the client obtains the test script.

Specifically, the client has a data input interface, a user can import a manually written test script through the data input interface, and the client obtains the test script through the data input interface. The test script is computer readable instructions in a test process.

Step 102: the client sends an excitation signal to the running simulation device according to the test script.

Specifically, the client executes each instruction in the test script, generates an excitation signal corresponding to the instruction, and sends the excitation signal to the operation simulation device. The client is provided with a test platform access interface, and the test platform access interface is used for executing a signal setting instruction of a test case and calling an interface based on a test verification environment to realize data excitation.

Step 103: and operating the simulation device to simulate the cabin display system to execute the test operation corresponding to the excitation signal and display a test display interface comprising the test operation result.

Specifically, the operation simulation device is used for simulating the cockpit display system, the cockpit display system comprises a CDS end and a UA end, and the operation simulation device comprises a display component, and the display component is used for displaying pictures in the simulated UA end. The operation simulation device receives the excitation signal, the CDS end in the operation simulation device is triggered by the excitation signal to execute the test operation corresponding to the excitation signal, and the operation simulation device displays the display state of each UA in the cockpit display system, namely a test display interface of a test operation result is displayed on a display interface in the operation simulation device. The client side can send an instruction to the server side after sending the excitation signal, wherein the instruction is used for instructing the server side to collect a test display interface of the operation simulation device. The client can also instruct the server to monitor the test display interface of the running simulation device in a preset time period.

Step 104: and the server collects a test display interface of the running simulation device according to the indication of the client.

In particular, the server is deployed in a high-performance computer with a graphics card and an image acquisition card. The client is also provided with a server communication interface, and the server communication interface realizes data interaction with the server based on http, and comprises: detecting the state of the server, testing the recognition result and the like. The line for transmitting data between the server and the client may be an ethernet line. The server receives the instruction and collects the test display interface of the operation simulation device, in this example, the test display interface of the operation simulation device can be collected by a camera.

Step 105: and the server side identifies the test display interface to obtain a test identification result.

And identifying the identifiable objects in the test display interface according to the image identification network trained to be converged in advance. The recognizable object in the test display interface may be text, an image of a control, etc.

A relevant recognition model library is constructed according to the characteristics of different controls in the cockpit display system by adopting a mode combined with a neural network, and a better recognition effect is achieved by preprocessing an image by utilizing a computer vision technology. The training that the service end that uses in the training process stores the image of the sample display interface of at least 3 different image acquisition equipment acquisitions, wherein, the neural network model that the system used in the aspect of deep learning has: the convolutional neural network CNN realizes the efficient classification of images by using convolutional operation based on a convolutional kernel and a multi-layer (convolutional layer, pooling layer and full-connection layer) structure; a fast RCNN network can also be adopted, and the RCNN network positions specified characteristic images in the test display interface based on the network obtained by training, such as pointers, characters and the like; and after the positioning is finished, calling other algorithms or network models to realize further content identification. An LSTM network can be adopted, is a special recurrent neural network, can control the transmission state through the gating state, is more favorable for forgetting some unimportant information while remembering the information needing to be memorized for a long time, and is used for identifying the character correlation model.

Step 106: and the server transmits the test identification result to the client.

Step 107: and the client determines the test result according to the received test identification result and the pre-stored identification result of the expected display interface.

Specifically, the client may pre-store an identification result of an expected display interface to be tested, compare the test identification result with the identification result of the expected display interface, determine that the test is qualified if the state of each control in the identification result is the same as the pre-stored state of each control, and determine that the test is unqualified if the states are different. After obtaining the test result, a test report may be generated, and the client supports exporting the test report into pdf or txt format.

It should be noted that the test script includes a plurality of test cases to be tested, the client supports adding the test script into the execution list and executing all the test cases in the script, and the execution process includes data excitation, waiting, result determination, and the like.

The embodiment of the application realizes a test method which can obtain the test script, execute the test script and record the test result; the full-automatic execution of the test case is realized; in the process of testing the script, the server controls the industrial camera to finish image acquisition and executes information (such as text content, color, control state and the like) extraction and identification result return of a specified identification target.

In one embodiment, the test script obtained in the test method is generated by the client, and a schematic diagram of the test script is shown in fig. 2.

Step 1011: and receiving the configuration information of each test item determined by the user, and generating a test script.

Specifically, the configuration information may be input by a user, for example, a test case editor may be displayed on a display interface on the client, the client edits the test case according to a selection instruction, the selection instruction is used to indicate a test control or an instruction in the test case editor selected by the user, and the selection instruction may be a click. For example, the display Interface receives an instruction of selecting an SET Control or other command controls related to parameters in an Interface Control Document (ICD) by a user, and the client dynamically provides selectable parameter prompts according to the currently selected Control of the user in combination with ICD parameter configuration when the parameters are input; the user can input parameters based on the optional parameter prompt; a test script is automatically generated.

The test method also comprises the step that the client queries the parameters in the interface definition file.

Specifically, the client receives a query request of a user, queries ICD parameters according to the parameters in the query request query interface definition file, so as to generate a test script quickly. For example, the query result is displayed, the input selection instruction is received, the single or multiple parameters in the query result are obtained, and the client side completes automatic generation of the test script corresponding to the test item based on the selected parameters. The test script includes the execution sequence of each test case.

It should be noted that, the test method adopts an asynchronous execution mechanism and an asynchronous test mechanism, so that the occupation of the main thread can be reduced, and the problem that the occupation time of the main thread is too long to influence the test speed is solved. An asynchronous test execution mechanism is adopted, namely the process control during the test execution is realized, and the problem of overlong response time caused by the occupation of a main thread is solved.

In the embodiment, the test script does not need to be manually compiled, and the test efficiency is improved.

In one embodiment, the client checks the test script, which is schematically illustrated in fig. 3.

Step 102-1: and carrying out validity detection on the test script according to a pre-stored interface definition file.

In a traditional mode, all test cases of a user are compiled based on Excel, and because ICD parameter configuration of an SSDL platform cannot be timely and effectively acquired in the compiling process, errors that signals cannot be identified in actual operation of a finally completed test script, namely CVT invalid errors, easily occur. Meanwhile, because the update frequency of the SSDL platform is fast in the production environment, a lot of time and effort are often consumed for verifying the correctness of the test script by a tester.

Before the test script is executed, validity verification is carried out on the test script, and the verified content comprises the validity of the parameters and the validity of the parameter values, so that the accuracy of the test script can be ensured.

The validity check of the parameter may be performed by: and acquiring an interface definition file of the test item, and acquiring parameters in the interface definition file. And acquiring the test script, detecting whether the test script comprises all parameters in the interface definition file of the test item, and if not, indicating that the current test script has missing parameters.

The method can also be realized by detecting whether the pre-stored parameter values are the same as the corresponding parameter values in the test script.

Step 102-2: and if the invalid information is detected to exist in the test script, indicating the position of the invalid information.

And outputting all error reasons and position information after the verification is finished so as to be checked by a user.

In the embodiment, because the test script comprises a plurality of test cases, if manual detection is performed, the workload is large, manual detection is not needed in the embodiment, the detection efficiency is improved, and the test accuracy is improved.

In one embodiment, the client stores each version of the test script in a database for review by a tester, a schematic of which is shown in FIG. 4.

Step 102-3: the client stores the test script of each version into the database, and the test script corresponds to respective identification information.

Specifically, the client is further provided with a database access interface, the database access interface is used for storing and reading data in the database, and the database can be a MySQL database. Because the test script is updated, each version of the test script can be stored in the database, and the identification information of each version of the test script is stored in the database. The procedure for saving the test script is as follows:

when the test script is executed, the client generates a unique round number according to the content and the version of the test script; and all relevant test process and result data including the acquired images are stored under the turn in the test execution process for the test personnel to view.

In this example, the test system may also monitor parameters selected by the user, and the user may select parameters from the input/output end of the client; the numerical values of the parameters are monitored, the monitoring duration can be set according to needs, and the monitored parameters can be refreshed manually or regularly by a system so as to adapt to different test scenes.

The client supports the import of the Excel format user test script, and can perform operations such as retrieval, update, check, deletion and the like on the test script of the import system.

In this embodiment, each version of the test script is saved, and the test script is subsequently queried for the tester to study.

In one embodiment, the client provides at least two test modes, which are schematically illustrated in fig. 5.

Step 104-1: the client displays at least two preset test mode options so that a user can select a test mode through a display interface.

Step 104-2: and the client responds to the selected test mode and tests the simulated cockpit display system according to the test mode.

The test mode includes two modes, an adaptive mode and a fully automatic mode. The self-adaptive mode refers to a hybrid test with supervision, namely, the self-adaptive mode can be automatically switched between a semi-automatic execution mode and a full-automatic execution mode according to the type of the test step; the full automatic test step will be skipped automatically; the full-automatic mode refers to unsupervised long-time full-automatic test, and semi-automatic test steps are automatically skipped, and errors which can occur in operation, such as: the use case contains illegal signals or SSDL calling errors and the like, the pop-up of the user confirmation dialog box is cancelled, and error information is recorded.

In the embodiment, a plurality of test modes are provided for the user to select, and the test flexibility is improved.

In one embodiment, the client may also process the onboard data, which is schematically illustrated in fig. 6.

Step 1011: and receiving the configuration information of each test item determined by the user, and generating the test script.

Step 102: and the client sends an excitation signal to the running simulation device according to the test script.

Step 108: the client acquires airborne data of the airborne equipment.

The onboard data indication refers to data collected by onboard equipment, such as an airplane. The on-board data may be imported to the client by other devices.

Step 109: the client analyzes the airborne data to obtain each parameter in the airborne data.

Step 110: and the client draws a curve corresponding to the airborne data according to each parameter in the airborne data and a pre-stored airborne interface definition file.

Specifically, the airborne data is analyzed, and each parameter in the airborne data is acquired, so that the airborne data is simulated, or the airborne data is analyzed and processed. The pre-stored airborne interface definition file can be distributed to the airborne data, and the curves corresponding to the airborne data are drawn according to the distribution time sequence.

It should be noted that the test system in this embodiment performs deployment test in a laboratory environment, and can continuously run for automatic test for more than 10 hours in an unsupervised laboratory environment, thereby ensuring continuous working time; in terms of the operation response time, the average operation response time is less than 1 second, and the heavy load operation response time is less than 2 seconds; when the length of the airborne data file to be analyzed is tested, the prototype system can analyze the airborne data file with the size exceeding 2GB, and the parameter number of a single airborne data file can realize the analysis of the airborne data file containing more than 200 parameters; recording the data processing time of a single recorded file during testing, and actually measuring and analyzing the airborne data file with the size of 2GB for about 6 minutes; in an image processing module of the server, pictures of different test display interfaces are used for testing, and numerical information, English sentences and line types in the pictures can be successfully identified. Wherein the numerical information includes: content, color, position and duration of the numerical value, and the English sentence comprises: appearance (appearance) and disappearance (disppear) of english sentences, color, position, and time of continuous display of the sentences; the line type includes: the state of the line (combination of color, length and thickness) and the duration.
