语言:python - 3.7.3 机器人框架 - 3.1.1 熟练程度:新手
我想从命令提示符将参数传递给 python 文件变量，然后想通过添加 python 文件作为变量从机器人文件打印相同的内容。
cmd (Variables) --> python file --> robot (print those variables)
但显然所有的尝试都没有产生预期的结果。任何指导将不胜感激。
注意:Robot 和 Python 文件在 pycharm IDE 中位于同一目录下。
命令行:-
1st try: robot -d Report -V test.py Test_sample.robot|py test.py test@test.com test@123 QA1
2nd try: robot -d Report Test_sample.robot|py test.py test@test.com test@123 QA1
3rd try: robot -d Report --Variablefile py test.py Test_sample.robot|py test.py test@test.com test@123 QA1
4th try: robot -d Report -V | py test.py test@test.com test@123 QA1| Test_sample.robot
python :-
import sys
username = str(sys.argv[1])
password = str(sys.argv[2])
environment = str(sys.argv[3])
机器人:-
*** Settings ***
Library SeleniumLibrary
Library Collections
Variables test.py
*** Test Cases ***
Pass variables from Python File
log to console The usr is: "${username}"
log to console The pwd is: "${password}"
log to console The env is: "${environment}"
预期:
usr 是:test@test.com 密码是:test@123 环境是:QA1
实际:

请您参考如下方法:
在您写的评论中:
My aim is to pass credentials from command line.
Robot 支持使用 --variable(和 -v)命令行选项。使用它会覆盖任何导入的变量或机器人文件中定义的变量。
例如，您可以在测试本身中为您的凭据设置默认值:
*** Variables ***
${USER} test@test.com
${PASSWORD} test@123
${ENVIRONMENT} QA1
*** Test cases ***
Example
log to console \n*****
log to console username: ${USER}
log to console password: ${PASSWORD}
log to console environment: ${ENVIRONMENT}
您可以使用 -v 或 --variable 从命令行修改这些值:
$ robot -v USER:bob -v PASSWORD:bob@123 -v ENVIRONMENT:QA2 ...
如果需要在 python 函数中访问这些变量而不传入它们，可以使用内置关键字 get_variable_value获取值:
from robot.libraries.BuiltIn import BuiltIn
...
user = BuiltIn().get_variable_value('${USER}')
