pytest简述--pytest.ini、allure、logging、assert的使用

1.assert

• assert xx 判断xx为真
• assert not xx 判断xx不为真
• assert a in b 判断b包含a
• assert a == b 判断a等于b
• assert a != b 判断a不等于b

2.pytest.ini

cmd执行：pytest --help #查看pytest.ini　　

pytest详细使用：https://cloud.tencent.com/developer/article/1640840

"""
pytest测试：
    测试文件以test_开头（以_test结尾也可以）
    测试类以Test开头，并且不能带有 init 方法
    测试函数以test_开头
    断言使用基本的assert即可

3.allure（官网地址：https://docs.qameta.io/allure/#_installing_a_commandline）

        Options:
          -h, --host
            This host will be used to start web server for the report.
          -p, --port
            This port will be used to start web server for the report.
            Default: 0
    plugin      Generate the report
      Usage: plugin [options]

4.logging

logging模块的详细使用：https://www.cnblogs.com/nancyzhu/p/8551506.html

https://blog.csdn.net/Runner1st/article/details/96481954

1）修改pytest.ini文件

pytest是从pytest.ini中读取log_cli配置的，默认是关闭的

[pytest]
log_cli = 1
log_cli_level = INFO
log_cli_format = %(asctime)s [%(levelname)8s] %(message)s (%(filename)s:%(lineno)s)
log_cli_date_format=%Y-%m-%d %H:%M:%S

2）用pytest -o方式重写，这个功能在pytest 3.4之后才实现，如下

pytest testcases.py -o log_cli=true -o log_cli_level=INFO　　

　logging模块使用：

logging.basicConfig(level=logging.INFO, filemode='a', filename='logger.log',
                    format='%(asctime)s - %(filename)s[line:%(lineno)d] - %(levelname)s: %(message)s')

def test_a():
    log.info('info message')
    log.debug('debug message')
    log.warning('warning message')
    log.error('error message')
    log.critical('critical message')
    assert 1, "pass"

allure+logging实例：

currentPath = os.path.dirname(os.path.abspath(__file__))
date = time.strftime("%Y-%m-%d_%H_%M_%S", time.localtime())

"""
    filemode='a',##模式，有w和a，w就是写模式，每次都会重新写日志，覆盖之前的日志
                    #a是追加模式，默认如果不写的话，就是追加模式
"""

if __name__ == '__main__': 
# 使用pytest生成报告：pytest --html=report.html # 
使用allure生成报告 
report_path = os.path.join(currentPath, 'results', 'reports', str(date))
allure_report_path = os.path.join(currentPath, 'results', 'allurereport', str(date)) 
test_folder = os.path.join(currentPath, 'testcases') 
pytest.main([test_folder, '--alluredir=%s' % (report_path), '-o log_cli=true']) #-o log_cli_level=INFO 
os.system('/usr/local/Cellar/allure/2.13.5/bin/allure generate %s -o %s/html --clean' % (report_path, allure_report_path)) # 替换为本地的 allure 安装路径
