=xxx ", wherein " xxx " it is relative path that web application functional module to be measured tests Java code, once starting, just open
Begin automatic test, whole process is without manual intervention.
5. a kind of web application automated testing method, it is characterised in that：Realize that step is as follows：
(1) substantial amounts of web page operation function is write based on Selenium, realizes basic browser operation and basic webpage behaviour
Make, provide the user the built-in function interface for using；To each web page operation, after web page element is found, pass through
Selenium interfaces, ask to the control sending action, including click on, and are input into certain key, choose drop-down menu, obtain its various
Value；A predetermined time is waited before and after action, to ensure that web page element can use, and action is accomplished；Use one
Single thread is completed to wait and performed；User is realized when test program is write by calling built-in function；
(2) self-defined language codes are compiled, Java code are generated, comprising T CompilerTools and preprocessor, with reference to C
Language syntax, using bison and flex instruments, designs and writes T CompilerTools and preprocessor, and compiler is compiled with C language
Write, preprocessor is write with python language；T CompilerTools with T language testing code be input, by preprocessor by its
C language style code is rewritten as, then by morphological analysis, syntactic analysis, generative grammar tree；Then, in traversal syntax tree process
In, generate Java code；T language is the simplified version of Java language and C language, need to only understand webpage test scene and simple volume
Journey rudimentary knowledge, just can easily use；According to the demand and feature of web application, write substantially using selenium interfaces
Function library, is write with Java language；According to the function library finished writing, built-in function list is added in compiler；
(3) script is write using python language, above procedure is combined, complete test flow is formed, in test scene and survey
After the completion of examination case designing, automatic operating is realized.
