使用机器人框架访问静态类变量? [英] accessing static class variables with robotframework?

问题描述

是否可以从加载到机器人框架中的库中访问静态类变量?

Is it possible to access static class variables from a library loaded into robot framework?

例如，假设我在我的 .robot 文件中包含以下 python 库:

For example, say I include the following python library in my .robot file:

foo = 'value'

class MyClass(self):
    bar = 'value'

在包含它的 .robot 文件中有没有办法引用 foo 或 bar?

Is there a way in the .robot file that included it to refer to foo or bar?

推荐答案

您可以通过使用 获取库实例，然后使用 扩展变量语法 以获取值.

You can get at these by getting a reference to the raw python module with Get Library Instance, and then use extended variable syntax to get the values.

例如，考虑一个名为 MyLibrary.py 的库:

For example, consider a library named MyLibrary.py:

# MyLibrary.py
foo = "this is foo"

class MyClass(object):
    bar = "this is bar"

您可以使用获取库实例 获取库的句柄:

You can access foo and bar by using Get Library Instance to get a handle to the library:

*** Settings ***
| Library | MyLibrary.py

*** Test Cases ***
| Example of accessing variables in a library
| | ${lib}= | Get Library Instance | MyLibrary
| | 
| | Should be equal as strings | ${lib.foo} | this is foo
| | Should be equal as strings | ${lib.MyClass.bar} | this is bar
