pytest灵魂产物

1.pytest:

默认命名规则：

测试类必须以TestXxx形式书写，即以Test开头，不能带有init方法
测试文件以test_*.py开头（以*_test.py结尾也可以）
测试函数以test_开头
断言使用基本的 assert 即可

实现一个简单的pytest project:

pydemo

--cases

　　--__init__.py

　　--test_order.py

　　--test_shipping.py

--conftest.py

--pytest.ini

--pytest.log

conftest.py:

作用提供全局灯具函数和全局调用工具方法

如接口登陆获取token

import  pytest
import uuid
@pytest.fixture()
def get_token():
    return uuid.uuid1().hex

pytest.ini:

pytest 的配置文件：

PYTEST_DISABLE_PLUGIN_AUTOLOAD set to disable plugin auto-loading

简单配置举例：

[pytest]
addopts = -s --pytest_report=pytest.html
testpaths=cases
console_output_style= classic
# SET LOGGER
log_cli = true
log_cli_level = DEBUG
log_format = %(asctime)s (%(filename)-4s: AT LINE %(lineno)-4s) %(levelname)-4s %(message)s
log_date_format = %Y-%m-%d %H:%M:%S
log_file=pytest.log


markers =
    order: for order
    logstics: for logstics
python_files = test_*  *_test  test*
python_classes =   Test*   test*
python_functions = test_*  test*

1.addopts 主要配置参数命令行参数，可以不用每次重复敲默认执行配置好的参数可以指定报告生成目录和重跑次数，还有打印详细程度

　　--pytest_report=pytest.html 指定html报告文件名称，默认在当前pytest.ini所在目录

2.testpaths 主要指要覆盖的测试目录，也就是跑那些测试目录

3.log_cli = true 设置日志控制台开关，打印日志作用

4.log_file 指定日志保存到文件的文件名

5.markers pytest的标记测试cases神器,可以只跑你标记的那部分特定模块case

6.对于测试执行顺序参考pytest-ordering

pip install pytest-ordering

用法：

第一个执行：@ pytest.mark.run(order=1)
第二个执行：@ pytest.mark.run(order=2)
倒数第二个执行：@ pytest.mark.run(order=-2)
最后一个执行：@ pytest.mark.run(order=-1)

@pytest.mark.run(order=2)
def test_laa():
    assert True


@pytest.mark.run(order=1)
def test_aaxx():
    assert True

7.markers 自定义标记：

多个标记换行书写

markers =

order: for order

logstics: for logstics

pytest mark testcase 案例：

pytest -m "order or logstics"

pytest -k 关键字匹配：

比如test case包含某些关键字的可以模糊匹配去执行：

接口参数化：

conftest.py:

import  pytest
import uuid
@pytest.fixture()
def get_token():
    return uuid.uuid1().hex

test_order.py

import pytest
import logging
logger=logging.getLogger('pytest')

@pytest.mark.order
@pytest.fixture()
def test_1(get_token):
    """ 为test_1的返回值给其他测试例用，通过pytest.fixture进行灯具化使其全局可用，pytest灵魂产物"""
    logger.debug("hello debug ")
    print('hello order订单 ..... {}'.format(get_token))
    return 329
@pytest.mark.order
def test_2(test_1):
    print("got is {}".format(test_1))

@pytest.mark.logstics
def test_logstics(get_token):
    logger.info("hello info ...")
    print('hello 物流..... {}'.format(get_token))
