Description

Automatic test system based on 3D application software framework and its method {AUTOTEST SYSTEM BASED FRAMEWORK OF 3 DIMENSIONAL APPLICATION SOFTWARE AND METHOD THEREOF}

The present invention relates to a three-dimensional application software framework based test technology, and more particularly, to an automated test system and method thereof.

Currently, 3D application software has been actively introduced into the CAE system field due to the expansion of the importance of enterprise R & D as well as the CAD and game fields.

Three-dimensional application software requires its own model and related modeling functions, and commonly requires rendering, display and selection of models, and management of Undo / Redo functions.

In particular, in 3D application software, most modeling functions begin with the model selection operation by the mouse on the view window, and the model selection operation involves 3 steps of complex model selection to perform one function. It is an important factor that determines the convenience and productivity of dimensional application software.

For example, the 3D modeling function selects the model to mirror the model. For the mirror function, the model element to be projected is selected by mouse clicking or dragging, and the second three vertices or polygons are selected. The 3D plane that is the reference of the projection is generated and the third plane is selected, and the position of the third plane is selected.

Accordingly, various technologies for supporting modeling of 3D images and 3D images and technologies for commercialization of home appliances and electronic devices based thereon have been actively developed.

In addition, in order to display 3D images and 3D images in home appliances and electronic devices, the development of corresponding contents should be accompanied. Various types of 3D application software have been proposed for this purpose.

Current commercially available 3D application software framework products include HOOPS of Tech Soft 3D (www.techsoft3d.com) in the US, and GLView, Norway's Ceetron ASA (www.ceetron.com) ExtremeToolkit from Codejock Software Inc. (www.codejock.com) in the United States.

Meanwhile, in the three-dimensional application software field, the demand for developing a dedicated analysis system for three-dimensional modeling is increasing, and in addition to the engineering field, it is expanding to the three-dimensional modeling application software development field such as medicine, education, and virtual reality.

Therefore, the role of development tools and components for 3D modeling is very important in the future and the related market is expected to continue to expand.

However, as the level of customer demand for 3D modeling application software increases, the quality development plan becomes more important as the software development period and cost increase as well as the size of the program, and when developing 3D modeling application software, You will need to test the performance and reliability of the 3D modeling application software.

For this purpose, the white box automatic test technique and the black box automatic test technique are presented.

The white box automatic test technology is a technology for automatically generating test cases based on source code and automatically testing the performance and potential errors of application software.

However, the conventional white box automatic test technique has a problem in that it is impossible to generate a test case reliably for a user's model selection operation in which an infinite number of cases exist by generating a test case based on source code.

In addition, the conventional white box automatic test technique requires a function call and variable value adjustment at the time of reproduction, as well as a problem of regenerating the test case when the source code is changed.

In addition, the conventional white box automatic test technique generates a test case by source code analysis, which makes it impossible to generate a view manipulation test case and a selection test case, and to store input / output data for each function. In this case, there is a problem in that the memory capacity is excessively increased and thus cannot be applied.

In addition, the black box automatic test technology is a technology for automating the test of the corresponding application software by generating and reproducing a test case by recording an event of a GUI manipulated by a user.

An example of the black box automatic test technique is US Patent No. 05335342 (name: Automated software testing system), which records user input operations such as a mouse and keyboard, and displays the result screen by the user input. It is a technique for verifying the test results by storing as, by reproducing the user input operation based on the stored data, automating the test of the application software and comparing the result screen with the stored image.

However, the conventional black box automatic test technique can reproduce and test a model selection operation by recording user input operations such as a mouse and a keyboard, but screen operations (eg, rotation, enlargement / If the user environment variables such as the speed of reduction and movement and the sensitivity (range) and method of model selection are changed after the test case is generated, the same work result cannot be obtained, which makes it impossible to test the function of the application software. That is, the conventional black box automatic test technique of recording a GUI event by a user to generate a test case regenerates a test case when the GUI is changed by changing the corresponding GUI element identifier or separating one GUI element into several. There is a problem to be done.

In addition, the conventional black box automatic test technique can only perform process test and performance test that record and manipulate user's operation as a test case, and perform performance test only. It is impossible to compare, and there is a problem that model data having complex and diverse components is difficult to analyze and cope with invalid result errors of modeling by simply comparing images. That is, in the conventional black box automatic test technique, the results are different according to the view manipulation processing speed, so it is impossible to replay the view manipulation only by the event, and the selection test is impossible because the view manipulation cannot be accurately reproduced. Model data cannot be compared due to many factors such as card, background color, and model color, and there is a problem that it is difficult to accurately identify an error point as well as to verify and analyze a functional unit because it is a GUI event unit test.

Therefore, in order to improve the conventional problem, the present invention records a function execution history by a user and automatically generates a test case so that the function of the corresponding application software can be used by using the test case regardless of GUI and source code change. The purpose of the present invention is to provide an automated test system and method based on the 3D application software framework, which can be used to test.

That is, the present invention records the user's work history and automatically generates a test case to enable accurate reproduction and verification of view manipulation and selection even when changing a preference, as well as comparison and verification of the result model data in functional units, and functional units. Its purpose is to enable the testing of functional units such as performance and pinpoint error points.

An automatic test processor which executes an automatic test on the software and provides the result of the execution to the user, and compares / verifies the model data stored in the DB for each test step in the unit function automatic test and the process test and automatically verifies the verification result. Use with a model test component that notifies the test processor And an automatic test controller for executing the operation of the automatic test processor when the automatic test is detected by the ruler.

When the automatic test of the unit function is executed, the automatic test processor executes the GUI auto test component to generate / store the corresponding test case, and based on the test case recorded in the DB, the unit test function of the unit function for the 3D application software is executed. Automatic test is executed, and when the process test is executed, the user's application software operation is recorded to generate / store the test case in the DB, and process test is performed on the 3D application software based on the test case recorded in the DB. And to provide the execution result to the user.
