4. the form of development and testing script is various, can use TXT file layout, also can use EXCEL formatted file, and test script is without the need to compiling, and exploitation, execution efficiency is high.
5. system can produce very exquisite test report, test macro daily record.Test report adopts XML format, can produce multiple format, as html, pdf, word etc. by XLST.Compare general test report, more flexibly, easy to understand.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is principle of the invention block diagram.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See Fig. 1, it is depicted as the automotive electronics test platform based on Python script provided by the invention.As seen from the figure, this test platform 100 mainly comprises these four parts of testing apparatus driver module 101, test library 102, test frame 103 and test script 104.
Testing apparatus driver module 101 in platform provides the driver of corresponding product to be tested 200, and its DLL using related libraries in Python to encapsulate product to be tested drives; If VISA equipment, utilize VISA to carry out equipment control, thus provide the hardware driving interface based on Python for upper strata test frame.
In the specific implementation, this module utilizes the storehouses such as pyVisa, pySerial, ctyp of Python, for the driver that the exploitation of different test products (equipment) 200 is corresponding.Generally need exploitation with device Driver for automobile electronics:
1.CANCaseXL drives: use ctype to encapsulate the driving of the DLL that CANCaseXL provides, thus control CAN, the bus that the automotive electronics such as LIN are conventional;
2. AWG (Arbitrary Waveform Generator) drives: use pyVisa to carry out the access of AWG (Arbitrary Waveform Generator);
3. programmable power supply drives: use pyVisa to carry out control programmable power supply;
4. analog quantity, number connect test board: use ctype to encapsulate dll form and drive;
5. wireless signal generator and radiofrequency signal resolver: use pyVisa to control;
6. relay matrix board: use ctype to encapsulate dll form and drive;
7. multimeter able to programme: use pyVisa to control
8. universal serial port equipment: use pySerial to carry out serial ports control.
Test library 102 in platform is RoboFramework test library, for the test frame on upper strata, is formed and tests key word accordingly.It connects with testing apparatus driver module data, and the testing apparatus driver of the hardware driving interface based on Python provided by testing apparatus driver module carries out step encapsulation, and being formed can the test key word of tested framework identification.
This test key word is realized by Python.
Test frame 103 in platform adopts RobotFramework test frame, because RobotFramework is the test frame of increasing income, specifically can reduce this framework, make it more be adapted to the test of automobile electronics.
This test frame 103 will provide running environment for test script 104, and its scheduling and controlling test script runs, and form corresponding test products test operation according to the content of test script; Simultaneously test frame 103 controls concrete test products by the testing apparatus program of encapsulation in test library 102, thus carries out encouraging product to be measured, and the test operation formed according to test script completes test and the measurement of product to be measured.
For all processes in test run, this test frame 103 will carry out record, form journal file, and test result will be recorded the report forming XML format.This report can use XLST to carry out the form of the forms such as format conversion formation html, pdf, word.
Test script 104 in platform drives based on the key word formed in test library and develops formation.Its method adopting key word to drive, can provide the form of multiple test script such as TXT, Excel.This test script is without the need to compiling, and exploitation, execution efficiency is high.The step of test is defined in test script 104, by condition, test data, variable etc., and the statement in test script can be resolved by tested framework 103, and run by framework.
The hardware driving interface data that product 200 to be tested and testing apparatus driver module 101 provide, when carrying out automobile electronics test, connects by the test platform formed thus.
Testing apparatus driver module 101 forms corresponding testing apparatus driver for the exploitation of required product 200 to be measured, thus provides the hardware driving interface based on Python for upper strata test frame.
Now, the testing apparatus driver of the hardware driving interface based on Python that testing apparatus driver module provides by RoboFramework test library carries out step encapsulation, and being formed can the test key word of tested framework identification.
Meanwhile, the test script developed formation and meet test request (as the step of test, by condition, test data, variable etc.) is driven based on the key word formed in test library.
After completing test script, scheduling and controlling test script runs by test frame, completes test to product to be measured.Concrete, test frame resolves the content of the test script transferred, thus parse corresponding key word, go out in test library to encapsulate the test key word of formation according to key word content recognition in the test script parsed, then the testing apparatus driver corresponding according to this test key word carrys out drived control product to be tested.This test frame reruns test script, forms corresponding test operation, utilize these test operations to control product to be tested and complete corresponding test process according to the content of test script.
Whole platform all adopts Python script to control from bottom to up, and having than general test platform more good characteristic, is a kind of test platform scheme of very applicable automobile electronics.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
