The whole network is super complete, and the pytest automated testing framework pytest.ini configuration file is detailed (actual combat)

Contents: Guide

foreword

The pytest configuration file can change the operation mode of pytest. It is a fixed file pytest.ini file, which reads the configuration information and runs according to the specified method.

Some files in non-test files
pytest are non-test files pytest.ini: the main configuration file of pytest, which can change the default behavior of pytest
conftest.py: some fixture configurations for test cases
init.py : identify this folder as a python package

Check the configuration option cmd execution of pytest.ini

Where should pytest.ini be placed?
Just put it in the root directory of the project, don't mess around, don't mess with other names

Common configuration items

marks

Function: The @pytest.mark.webtest decorator is added to the test case. If the marks option is not added, warnings will be reported

Format: list list type
Writing method:

[pytest]
markers =
    weibo: this is weibo page
    toutiao: toutiao
    xinlang: xinlang

xfail_strict

Effect: Setting xfail_strict = True allows those test cases marked as @pytest.mark.xfail but actually passing XPASS to be reported as failed

Format: True, False (default), 1, 0

Writing:

[pytest]

# mark标记说明
markers =
    weibo: this is weibo page
    toutiao: toutiao
    xinlang: xinlang

xfail_strict = True

Specific code example
When xfail_strict = True is not set, the test result shows XPASS

@pytest.mark.xfail()
def test_case1():
    a = "a"
    b = "b"
    assert a != b

collecting ... collected 1 item

02断言异常.py::test_case1 XPASS [100%]

============================= 1 xpassed in 0.02s ==============================

When xfail_strict = True is set, the test result shows failed

collecting ... collected 1 item

[XPASS(strict)]

[XPASS(strict)] 
=========================== short test summary info ===========================

============================== 1 failed in 0.02s ==============================

addopts

Function: The addopts parameter can change the default command line options. When we enter a bunch of instructions in cmd to execute the use case, we can use this parameter instead, saving the repetitive work of typing commands

For example: if you want to test and generate a report, if you fail, rerun it twice, run it twice in total, and test it through distribution. If you write it in cmd, the command will be very long

pytest -v --rerun=2 --count=2 --html=report.html --self-contained-html -n=auto

It is not realistic to knock like this every time, addopts can perfectly solve this problem

[pytest]

# mark
markers =
    weibo: this is weibo page
    toutiao: toutiao
    xinlang: xinlang

xfail_strict = True

# 命令行参数
addopts = -v --reruns=1 --count=2 --html=reports.html --self-contained-html -n=auto

After adding addopts, we only need to type pytest in cmd to take effect.

norecursedirs

Function: When pytest collects test cases, it will recursively traverse all subdirectories, including some directories that you know you don't need to traverse. In this case, you can use the norecursedirs parameter to simplify the search work of pytest.

default setting:

norecursedirs = .* build dist CVS _darcs {
    
    arch} *.egg

Correct writing: Multiple paths are separated by spaces

[pytest]

norecursedirs = .* build dist CVS _darcs {
    
    arch} *.egg venv src resources log report util

Change test case collection rules:

pytest’s default test case collection rules
File names start with test_*.py files and * test.py
functions starting
with test Classes starting with Test cannot contain init methods Methods
in classes starting with test_

We can modify or add this use case collection rule; of course, it is recommended to add it to the original rule, as follows

[pytest]

python_files =     test_*  *_test  test*
python_classes =   Test*   test*
python_functions = test_*  test*
