WinRunner学习

        1，report_msg  :  prints a user-defined string  expression to the test run report

        2,   pause  :     The pause function stops the test run and displays a string expression in a message box on the screen
          report_Msg和pause是在Win下显示的信息，在UNIX下是printf

        3,   radio_button :  控制按扭属性是ON还是OFF，如：
        set_window ("Flight Reservation", 3);
        button_set ("{class: radio_button, MSW_class: Button, label: Business}", ON);

        4,    return[expression]  ： 返回值

        5，脚本格式 ：
         Test Header :
         ---------> Test Name
         ---------> Subject
         ---------> Test Creator
         ---------> Date of creation/Date of revision
         ---------> Purpose of the test
         正式脚本

        6，static const = ;放在脚本最前面

        7，[static/public] = [];静态和公共变量

        8， 三种判断方式
         ------->if (win_exists ("Window_Name") == 0) {
          set_window ("Window_Name");
         --------> if (!win_exists ("Window_Name")) {
           set_window ("Window_Name");
         ---------> if (win_exists ("Window_Name") == E_OK) {
            set_window ("Window_Name");

        9,自己创建错误提示代码的协定
         -------->Error codes should be in capital letters.必须为大写字母
         -------->Error codes should begin with the letter “E” followed by an underscore   (for example, E_MY_ERROR).
          -------->Error code numbers should include a dash “-” followed by a five digit   value (for example, -31001).
         -------->Error codes should be defined as public in a library or initialization test   or example, public const E_MY_ERROR = -31001).

        10, GUI_Load和GUI_Unload
         GUI_Load(file_name):   加载GUI的MAP文件，加载的是全路径
         GUI_unload( ): 释放GUI文件
         如：
        # This loads the GUI file

        GUI_load ("E:\\file1.gui");
        GUI_list_map_buffers(out_file, out_buffer);

        # The out_file contain the loaded gui file file1.gui.

        GUI_unload (file1.gui);

        # This unloads the GUI file

        GUI_list_map_buffers(out_file, out_buffer);
        # Now the out_file array does not contain file1.

        11，tl_step  :  可以输出一些的信息

        12,   Function Header
        The function header is placed above a user defined function. Like the Test
        Header, the function header is enclosed by the "#" symbol and stores
        information about the function:
        >Function Name
        >Descrīption or purpose of the function
        >Input parameters
        >Output parameters
        >Return Values

        For example:
        ################################################################
        # FUNCTION: get_flight_from_table
        # PURPOSE: This function is static only to this file. It selects a flight from the
        # flight table using a given flight number. Also uses split() function to access the
        # flight number from the table.
        #
        # INPUT PARAMS: flight_num   The flight number to be selected.
        # OUTPUT PARAMS:   none
        # RETURN VALUES: Standard return values.
        ###############################################################
        static function get_flight_from_table (in flight_num){...

        13, TSL includes four types of functions:
        >Context Sensitive functions perform specific tasks on GUI objects, such as
        clicking a button or selecting an item from a list. Function names, such as
        button_press and list_select_item, reflect the function’s purpose.
        >Analog functions depict mouse clicks, keyboard input, and the exact
        coordinates traveled by the mouse.
        >tandard functions perform general purpose programming tasks, such as
        sending messages to a report or performing calculations.
        >Customization functions allow you to adapt WinRunner to your testing
        environment.
