1、Robot Framework库的路径

E:\Program Files\Python3.7.1_X64\Lib\site-packages\robot\libraries

2、自定义系统关键字

• E:\Program Files\Python3.7.1_X64\Lib\site-packages下创建文件夹MyLibrary
• MyLibrary下创建count.py

#coding=utf-8
class Count(object):
    def add(self, a, b):
        '''
        用于计算a、b两数相加的结果，例：
        | add | a | b |		
        '''
        return int(a) + int(b)

    def sub(self, a, b):
        '''
        用于计算a、b两数相加的结果，例：
        | add | a | b |
        '''
        return int(a) - int(b)


if __name__ == "__main__":
    c = Count()
    result=c.add(1, 2)
    print(result)
    assert result == 3

• MyLibrary下创建__init__.py

#coding=utf-8
from MyLibrary.count import Count

__version__='1.0'

class MyLibrary(Count):
	ROBOT_LIBRARY_SCOPE='GLOBAL'

3、查看自定义的系统关键字

• suite中导入MyLibrary
  
• RIDE中按F5，可以查看定义的关键字
