python pytest框架发送邮件

Python的pytest是一个流行的单元测试框架，主要用于编写和运行测试代码，确保程序的正确性。如果你需要在pytest测试中发送电子邮件，通常会用到第三方库如`smtplib`（用于发送邮件的SMTP协议）或者更高级的库如`selenium-requests`（结合了requests和selenium的邮件功能）。然而，pytest本身并不直接支持邮件发送，它是专注于测试的。

以下是一个使用`smtplib`在pytest中发送简单邮件的基本示例：

import smtplib
from email.mime.text import MIMEText

def test_send_email():
    sender = "your-email@example.com"
    receiver = "recipient-email@example.com"
    password = "your-password"  # 可以从环境变量或配置文件获取
    subject = "pytest test email"
    body = "This is a test email sent from pytest."

    msg = MIMEText(body)
    msg['Subject'] = subject
    msg['From'] = sender
    msg['To'] = receiver

    try:
        server = smtplib.SMTP('smtp.example.com', 587)  # 邮箱服务端
        server.starttls()  # 加密连接
        server.login(sender, password)
        server.sendmail(sender, receiver, msg.as_string())
        server.quit()
        print("Email sent successfully.")
    except Exception as e:
        print(f"Failed to send email: {e}")

# 在pytest中执行这个测试
def test_suite():
    test_send_email()

要执行此测试，你需要在pytest命令行中运行：

pytest -v test_email.py
