Description
Technical field
The invention belongs to and relate to virtual instrument technique, domestic electric appliances controller measuring technology and component frame technical field.
Background technology
Domestic electric appliances controller and Complete set manufacturers generally carry out according to the process shown in Fig. 1 the technological process of production of domestic electric appliances controller.
The process procedure of typing test therein mainly is that the function accordance and the performance of product (be domestic electric appliances controller, below corresponding place all abbreviate product as) are tested.At this moment needing independently the tester connects the true peripheral hardware of corresponding household electrical appliances to domestic electric appliances controller and carries out true operation.The method of test is general to be adopted by test of test outline and random test.The test outline is to be made according to the function of product by the designer in the design phase of product, generally is exactly the function accordance of test products by the test of test outline.Random test is according to test experience in the past product to be carried out random operation by experienced tester, with the logic error of hiding of measuring the part of software design in the product or defective (as some link lack the Software Anti-interference measure, overflow or the like on the logical condition border).No matter be that traditional handicraft all is to be carried out by hand by experienced tester by test of test outline or random test.
In the production practices of product, find that gradually there is following defective in traditional handicraft:
The serious dependence manually, the close examination of test result all leans on people's sense organ to carry out, and the demonstration of test result and expression way are also very limited.Can cause following consequence, the first is because the tester is subjected to the restriction of the human physiology limit to cause some test not carry out, as the clock accuracy of the frequency of test buzzer, test Millisecond, test certain boundary condition or the like by the continuous running that reaches a few days; Its two test result seriously relies on tester's quality, virtue, health and family status, and these factors all are that test process is uncontrollable; Its three reliability of testing result reduces.
The serious test experience that relies on, particularly in the work of random test, the mistake on the testing software design logic how, need for many years design and the experience of test domestic electric appliances controller.So usually software design for many years, conscientious, careful by doing in traditional manufacturer, health and the good slip-stick artist of family status are the Test Engineer.And the process procedure of this serious dependence experience is understood owing to the production factors scarcity, is subjected to factors such as external disturbance is serious to become the bottleneck of whole production technological process.
The test experience can not be accumulated, and it is qualitative and lack quantitative methods to make test job become a kind of deflection.The effect that is product test so all can be different at same slip-stick artist's different times.
The test process automation degree is low, as producing test report etc. automatically.Can't satisfy the informationalized requirement of modern enterprise.
Summary of the invention
The objective of the invention is to utilize correlation technique of the present invention to transform the typing test production technology link of domestic electric appliances controller development and production, reduce the consequence of this link because of artificial serious dependence is caused, improve the automaticity of this link, improve the computed domestic electric appliances controller auxiliary test unit and the method for testing thereof of the reliability of typing test activity.
