如何使用不同的参数和不同的结果模拟被调用两次的命令

import subprocess

# 定义要模拟的命令及其参数和结果
commands = [
    {'cmd': 'ls', 'args': ['-l'], 'result': '文件1\n文件2\n文件3\n'},
    {'cmd': 'echo', 'args': ['Hello, World!'], 'result': 'Hello, World!\n'}
]

# 模拟被调用两次的命令
for command in commands:
    cmd = [command['cmd']] + command['args']
    result = command['result']

    # 执行命令
    process = subprocess.Popen(cmd, stdout=subprocess.PIPE)
    output, _ = process.communicate()

    # 比较命令执行结果与预期结果
    if output.decode('utf-8') == result:
        print('命令执行成功！')
    else:
        print('命令执行失败！')

from unittest.mock import patch

# 定义模拟的命令结果
mock_result = '模拟的命令结果'

# 定义被调用的命令
def my_command(*args):
    return mock_result

# 使用patch装饰器替换命令的执行结果
@patch('subprocess.check_output', side_effect=my_command)
def test_command(mock_subprocess):
    # 调用两次命令
    result1 = subprocess.check_output(['ls', '-l'])
    result2 = subprocess.check_output(['echo', 'Hello, World!'])

    # 比较命令执行结果与预期结果
    assert result1 == mock_result
    assert result2 == mock_result

# 执行测试
test_command()
