用python的pytest完成: f1为fixture函数,传入两个参数,test_2函数调用f1,传入参数为1,2

Sure! Here's an example of how you can use pytest in Python to accomplish this:

import pytest

@pytest.fixture
def f1():
    def _f1(a, b):
        return a + b
    return _f1

def test_2(f1):
    result = f1(1, 2)
    assert result == 3

In the above code, we define a fixture function `f1` using the `@pytest.fixture` decorator. This fixture function takes two arguments `a` and `b` and returns their sum.

The `test_2` function is a pytest test function that utilizes the `f1` fixture. It calls `f1` with arguments 1 and 2 and asserts that the result is equal to 3.

To run this test using pytest, save the code in a file (e.g., `test_example.py`) and run the following command in the terminal:

pytest test_example.py

I hope this helps! Let me know if you have any more questions.
