将位于 python 文件中的 python 类中的函数导入机器人框架

Question

Consider I have this file hierarchy for my project:

• my_project (root folder)
  • Resources
    • python_file.py containing two classes: FirstClass and SecondClass
  • Tests
    • test_suite.robot

Here are the classes how they look like

    class FirstClass:
        def my_method:
            pass

    class SecondClass:
        variable = {
              key1: value1,
              key2: value
           }

Firstly, I want to use my_method in .robot file by importing whole class FirstClass using relative path.

Secondly, I want to use a dictionary from SecondClass by importing this class somehow (also using relative path).

Is this possible in RF?

Thanks in advance.

While a class might not be directly accessible, its methods can be accessed using objects/instances within python. To do so, in your Setting you would have to add the python file -

*** Settings ***
Library    ../Resources/python_file.py

Now within your Test Cases you can invoke the function like any other keyword although it would be advisable to use the file name as well to prevent any confusion to the compiler as follows

*** Test Cases ***
${result}=    python_file.foo #Calls the new function foo that calls my_method

And within the python_file.py create another method -

def foo():
    obj = FirstClass()
    return obj.my_method()

Or

def bar():
    return SecondClass.variable
