Pytest 仅通过了模块中我的 cli 的第一次测试，而下一次测试失败了，无视排序。 为什么会这样？

Question

pytest 版本：pytest==7.1.2

打字机版本：打字机==0.4.1

我有这个测试文件

import pytest
from mimicbot import (
    __app_name__,
    cli,
    config,
)
import typer
from typer.testing import CliRunner, Result
from configparser import ConfigParser
from pathlib import Path 

default_path = Path(config.APP_DIR_PATH)
default_config = default_path / "config.ini"

@pytest.fixture
def mock_config_path(tmp_path):
    tmp_config_path = tmp_path / "config.ini"
    config.init_app(tmp_path)
    # copy a file from path default_config and paste it to tmp_config_path
    tmp_config_path.write_text(default_config.read_text())
    return tmp_config_path


class TestMine:
    # Must have an initialized mimicbot config to the default parameters
    def test_successful_mine(self, mock_config_path, tmp_path):
        parsed_config = ConfigParser()
        parsed_config.read(str(mock_config_path))
        runner = CliRunner()
        result = runner.invoke(cli.app, ["mine", "-ap", tmp_path])

        data_path = tmp_path / "data" / parsed_config.get("discord", "guild") / parsed_config.get("general", "session")
        messages_path = data_path / "messages.csv"

        assert "Successfully mined data." in result.stdout
        assert result.exit_code == 0
        assert messages_path.exists()
    
    def test_failed_mine_api_key(self, mock_config_path, tmp_path):
        parsed_config = ConfigParser()
        parsed_config.read(str(mock_config_path))
        parsed_config.set("discord", "api_key", "xxFAKExx")
        with open(str(mock_config_path), "w") as config_file:
            parsed_config.write(config_file)

        runner = CliRunner()
        result = runner.invoke(cli.app, ["mine", "-ap", tmp_path])

        assert "Error: API_KEY_ERROR" in result.stdout
        assert result.exit_code == 1

我正在运行这两个依赖于等待 cli 执行的测试。 cli 依赖于一个需要几秒钟才能运行的函数。

不管我如何订购这两个测试，我总是得到相同的结果：第一个（依次）通过，而下一个失败。

运行前一个文件时，我得到以下回溯。

然后，当测试的顺序（文件开始到结束）被翻转时，我得到以下回溯：

最后，两个文件似乎都发生了相同的问题，因为它们以相同的方式失败。

我还尝试将测试移动到单独的文件中（我认为是垃圾解决方案），但也以同样的方式失败。

可能是什么问题呢？ 我该如何解决？

提前致谢！
