• pytest fixture及conftest详解三 (pytest.ini配置文件)

    在这里插入图片描述

    文章目录

    一、pytest.ini介绍

    是pytest框架的主配置文件，实际生产中主要用来规范日志的格式或日志文件保存的位置，增加用例标签等等，总之简单易用，属于pytest学习的重要知识点。

    特别注意:
    pytest.ini文件命名不能修改，文件中第一行必须用【pytest】申明这是一个pytest的ini文件

    二、自定义mark标签

    我门在编写自动化测试用例时，会有各种类型的场景用例，我们又不想一次性运行全部，只想运行其中的几个，这时我们可以借助mark标签来管理测试用例，mark标签是任意取的，但是要避开Python和pytest关键字，运行标签用 - m 来运行，如：pytest -m div testcases/menus/test_menus1.py::TestMenus

    特别注意:
    多个标签要换行，且不能在顶格写，要有空格

    在这里插入图片描述

    1.案例:只执行div的测试用例

    # encoding=utf-8
import pytest

class TestMenus:

    @pytest.mark.div
    def test_menu1(self):
        assert 1 == 1

    @pytest.mark.div
    @pytest.mark.add
    def test_menu2(self):
        assert 1 == 1

    def test_menu3(self):
        assert 2 == 5


if __name__ == '__main__':
    pytest.main()

    2.注册标记来防止拼写错误

    自定义标记可以简化测试工作，让我们用指定的标记运行某个测试子集。但是，标记很容易拼错，比如把@pytest.mark.smoke拼成@pytest.mark.somke，默认情况下。这不会引起程序错误。pytest会以为这是你创建的另一个标记。为了避免拼写错误。可以在pytest.ini文件里注册标记
    标记完可以通过:pytest --markers 查看
    在这里插入图片描述

    案例1:注册标记使用正确

    [pytest]
;python_files = check*
;python_functions = check*
;python_classes = CHECK*

markers =
    smoke: Run the smoke test functions for tasks project
    get: Run the test functions that test tasks.get()
    div
    add
addopts= -v -s --capture=no

        assert 1 == 1


    @pytest.mark.smoke
    def test_menu2(self):
        logging.info('执行测试用例2')
        assert 1 == 1

    def test_menu3(self):
        logging.info('执行测试用例3')
        assert 2 == 5

    案例2:注册标记使用错误

    执行命令:pytest -m smoke1(smoke1没有注册)
    把smoke故意写错了，也没有报错，只是给我们一个警告，只需要我们在ini里注册下就不会有警告了

    pytest -m smoke1

    3.指定pytest忽略某些目录(norecurse)

    pytest执行测试搜索时，会递归遍历所有子目录，包括某些你明知道没必要遍历的目录。遇到这种情况，你可以使用norecurse选项简化pytest的搜索工作。
    在这里插入图片描述

    pytest.ini
    把menus用例目录注销了,不会去执行这个目录下的用例了

    [pytest]

norecursedirs = .* venv menus *.egg dist build
url = https://blog.csdn.net/YZL40514131
markers =
    smoke: Run the smoke test functions for tasks project
    get: Run the test functions that test tasks.get()
    div
    add
addopts = -v -s --capture=no

log_cli = true
log_cli_level = info
log_cli_format = %(asctime)s [%(levelname)s] %(message)s (%(filename)s:%(lineno)s)
log_cli_date_format = %Y-%m-%d %H:%M:%S
log_file = ./logs/all.log
log_file_level = info
log_file_format = %(asctime)s [%(levelname)s] %(message)s (%(filename)s:%(lineno)s)
log_file_date_format = %Y-%m-%d %H:%M:%S

    也可以指定多个目录

    norecursedirs = .* venv menus works *.egg dist build

    • 1

    4.指定测试目录(testpaths)

    norecuredirs告诉pytest哪些路径不用访问，而testpaths则指示pytest去哪里访问。testpaths是一系列相对于根目录的路径，用于限定测试用例的搜索范围。只有在pytest未指定文件目录参数或测试用例标识符时，该选项才有作用

    pytest.ini
    如果我们只想执行testcases/menus下的测试用例，则可以把testcases/menus放到testpaths里

    [pytest]

testpaths = testcases/menus
url = https://blog.csdn.net/YZL40514131
markers =
    smoke: Run the smoke test functions for tasks project
    get: Run the test functions that test tasks.get()
    div
    add
addopts = -v -s --capture=no

log_cli = true
log_cli_level = info
log_cli_format = %(asctime)s [%(levelname)s] %(message)s (%(filename)s:%(lineno)s)
log_cli_date_format = %Y-%m-%d %H:%M:%S
log_file = ./logs/all.log
log_file_level = info
log_file_format = %(asctime)s [%(levelname)s] %(message)s (%(filename)s:%(lineno)s)
log_file_date_format = %Y-%m-%d %H:%M:%S

    5.如果我既指定了testpaths和 norecursedirs ，而且两个是一样的，结果会怎样

    在这里插入图片描述
    从上面两次的运行结果可以看出，如果既指定了testpaths和 norecursedirs ，而且两个是一样的，则是按照testpaths执行的

    collected 3 items

    三.自定义运行时的默认参数

    pytest有多个经常使用的参数，如 - vs 来打印更详细的信息，但是每次都要手动输入很麻烦，例如上个案例 pytest -vs -m div testcases/menus/test_menus1.py::TestMenus
    这是需要用到 addopts 配置默认运行参数

    特别注意
    addopts 运行时参数（可添加多个命令行参数，空格分隔，所有参数与命令行一致）

    案例:

    pytest.ini

    [pytest]
markers =
    smoke: Run the smoke test functions for tasks project
    get: Run the test functions that test tasks.get()
    div
    add
addopts= -v -s

    五.自定义测试文件命名规则

    测试用例默认命名规则

    除非pytest命令指定到测试用例文件，否则测试用例文件命名应该以 test_开头或者以_test结尾。
    测试函数命名，测试类的方法命名应该以test_开头。
    测试类命名应当以Test开头。
    tips: 测试类的不应该有构造函数。

    python_files 自定义测试文件命名规则
    python_classes = Test_* 自定义测试类命名规则
    python_functions= test_* check_* 自定义测试方法命名规则

    在这里插入图片描述

    pytest 框架可以通过pytest.ini配置文件自定义命名规则，在某些特定场景下可能会用到。

    特别注意:
    想控制多种文件类型，用空格隔开

    案例

    pytest.ini文件

    [pytest]
python_files = check*
python_functions = check*
python_classes = CHECK*

markers =
    smoke: Run the smoke test functions for tasks project
    get: Run the test functions that test tasks.get()
    div
    add
addopts= -v -s --capture=no


log_cli = true
log_cli_level = info
log_cli_format = %(asctime)s [%(levelname)s] %(message)s (%(filename)s:%(lineno)s)
log_cli_date_format = %Y-%m-%d %H:%M:%S
log_file = ./logs/all.log
log_file_level = info
log_file_format = %(asctime)s [%(levelname)s] %(message)s (%(filename)s:%(lineno)s)
log_file_date_format = %Y-%m-%d %H:%M:%S

    check_menus.py

    @pytest.mark.add

        logging.info('执行测试用例2')
        assert 1 == 1

    def check_menu3(self):
        logging.info('执行测试用例3')
        assert 2 == 5


if __name__ == '__main__':
    pytest.main()
