Pytest：如何从测试方法外部访问命令行参数

Question

I have a NON-TEST method defined in a python module. (Say- read_test_data()), which has to consume the test_ID's passed through the command line. I have another test-method, defined in a class, which calls read_test_data() and gets the values from there. Now, how can I get the values from command line arguments, into the non-test method?

Answer 1

if your function is located on a file called file_name.py, that would be something like this:

import argparse

def read_test_data(testcase_id):
    print(testcase_id)

if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument("-t", "--testcase_id", help="test case id helper documentation")
    args = parser.parse_args()
    read_test_data(args.testcase_id)

if you make a call from command line like:

python file_name.py --testcase_id "test1A, test1B"

You will get as output:

test1A, test1B
