如何运行 python 脚本来测试我自己的 shell？

Question

I am making my own shell and I want to make a python script to automate tests. I would like to run both programs like this: ./my_shell | test.py ./my_shell | test.py

How can I do that ?

Answer 1

import os


def command(command):
    exit_status = os.system(
        "echo \"%s\" | ./42sh > output 2> errout" % command)
    with open("output", "r") as output_file:
        output = output_file.read()
    with open("errout", "r") as error_file:
        error = error_file.read()
    return output, error, exit_status / 256


out, err, ex = command("ls -a")
