如何使用机器人框架运行pytest测试用例？

Question

我们已经使用pytest功能使测试用例自动化，但是现在我们必须使用Robot框架来报告和运行测试用例。是否可以使用机械手运行pytest测试用例。

Pytest文件：test_sample.py

import pytest

@pytest.mark.parametrize("test_input,expected", [("3+5", 8), ("2+4", 24), ("6*9", 54)])
def test_eval(test_input, expected):
        print(test_input, expected)
        assert eval(test_input) == expected

将由机器人文件调用的执行文件。

exec.py

import os
import sys

def run_test_cases_of(sample_Test):
    os.system("pytest -s -v test_sample.py" )

Robot file which is runner: 


 ******settings ***
 Library  test_sample.py
 Library  exec.py


 ****Test Cases ***

 Running test case

    #test eval # When running through this robot is asking for argument
    run test cases of   sample_test #When throygh this robot understaing there is only one test case
