机器人框架-导入外部python库不起作用

Question

我有一个机器人框架项目，下面的文件夹和文件结构。

​

​

logger.py文件如下所示。

def log_into_console():
    print("log_into_console() method executed")

message_printer.py文件如下所示。

# This line cause the problem. it says "ModuleNotFoundError: No module named 'Lib.Common'"
from Lib.Common.logger import log_into_console

def print_message():
    print("print_message() method executed")
    log_into_console()

我想在我的机器人测试用例中调用上面的print_message()函数，如下所示。

*** Settings ***
Library    SeleniumLibrary
Library    ../Lib/Util/message_printer.py

*** Test Cases ***
My Test Robot Test Case
    print message

我的问题是当我执行测试时，它会抱怨它找不到Lib.Common模块。当我执行测试时，我会出错。

有人能帮我解决这个问题吗。

Answer 1

#1:要解决"ModuleNotFoundError: No模块名为‘Lib.Common’“的错误，请尝试以下一个

from logger import log_into_console

def print_message():
    print("print_message() method executed")
    log_into_console()

由于函数log_into_console位于同一个目录中，所以可以直接使用记录器而不是要获得更多详细信息，请参阅下面的链接https://intellipaat.com/community/9924/call-a-function-from-another-file-in-python#:~:text=If%20you%20want%20to%20call,b)

#2:您可以在机器人文件中进行以下更改，以解决名称为“打印消息”的No关键字找到的错误

*** Settings ***
Library    SeleniumLibrary
Library    Lib

*** Test Cases ***
My Test Robot Test Case
    Lib.message_printer

当你尝试这个时，如果你面临任何错误，请告诉我！
