Pytest的一些实用技巧

import pytest


@pytest.fixture()
def new_one():
    yield dict(a=1, b=2)


@pytest.fixture(scope='module')
def always_one():
    yield dict(a=1, b=2)


def test1(new_one:dict, always_one:dict):
    assert new_one'a' == 1
    assert always_one'a' == 1
    new_one'a' = -1
    always_one'a' = -1


def test2(new_one:dict, always_one:dict):
    assert new_one'a' == 1
    assert always_one'a' == 1

import pytest


def test():
    with pytest.raise(KeyError) as error:
        data = dict(a=1, b=2)
        data.pop('c')
    assert 'c' in str(error)

[tool:pytest]
python_paths = . ;好在根目录下运行py.test的时候扫描到需要测试的包
norecursedirs = .git .tox venv* requirements*; 不扫描的目录
python_files = test*.py ;测试代码
filterwarnings =
    ignore::DeprecationWarning ;在输出中过滤掉特定的警告信息

py.test --cov=app --cov-report=xml --cov-report=html
