我是Python和Robot Framework的新手。对于学习的测试项目我创建:

general_scenario.robot:

*** Settings ***
Documentation    Suite description
Resource          ../resource.robot
*** Variables ***
...


*** Test Cases ***
[Config] Extend Config Model
[Tags]                model
Extend Config Model

然后,创建关键字lib:

...
class ModelLibrary(ModelAbstract):
...
@keyword('Extend Config Model')
    def extend_config_model(self):
        moGen = ModelGeneral.__init__(self, 45.5, 2.04)
        moAdd = ModelAdditional(True, 0.34)
        moRoute = ModelRoute("path")
        mo = Model("ship002", moGen, moAdd, moRoute)
        print(mo.name, mo.general, mo.additional, mo.route)
        pass

我想使用helper(数据模型类)helper.Model.py,它在这个关键字lib中导入,如下所示:

from helper.Model import ModelGeneral, ModelAdditional

也有resource.robot文件:

Library     libs/ModelLibrary.py
Library     libs/EmulationLibrary.py
Library     helper/Model.py

所以>pybot general_scenarios.robot

[ ERROR ] Error in file 'C:\..\resource.robot': Importing test library 'C:\..\libs\ModelLibrary.py' failed: ModuleNotFoundError: No module named 'helper'
Traceback (most recent call last):
  File "C:\..\libs\ModelLibrary.py", line 5, in <module>
    from helper.Model import ModelGeneral, ModelAdditional

and:
[ ERROR ] Error in file 'C:\..\resource.robot': Test Library 'Model' expected 4 arguments, got 0.

修复args未修复导入测试库失败。无法理解导入普通py模块的错误。

您缺少帮助程序模块,以下命令将在您的cmd中安装该模块

pip install helper

每当缺少模块名称时,您都可以通过pip或第三方进行安装
