html随机选数代码介绍 html随机数生成器( 三 )

[dechin@dechin-manjaro pytest]$ pytest --versionpytest 6.2.2pytest单元测试用例撰写根据前面一个章节中的random_number.py文件，我们可以对照的写一个简单测试用例：
# test_random_number.pyimport pytestfrom random_number import random_number_generator as rngdef test_random_number_generator():for i in range(10):random_number = rng()assert random_number == 0 or random_number == 1该测试用例的含义为：导入rng函数之后，测试10次该函数的返回值，所返回的值必须是0或者1的随机数，如果输出了这两个数字以外的返回结果，那么说明这个随机数产生器功能上存在问题。基于pytest的测试代码可以通过如下的指令来运行：
[dechin@dechin-20n2s01200 pytest]$ py.test=========================================== test session starts ============================================platform linux -- Python 3.8.5, pytest-6.2.2, py-1.9.0, pluggy-0.13.1rootdir: /home/dechin/projects/2021-python/pytestplugins: cov-2.11.1, metadata-1.11.0, html-3.1.1collected 1 itemtest_random_number.py .[100%]============================================= warnings summary =============================================../../../anaconda3/lib/python3.8/site-packages/projectq/ops/_gates.py:118/home/dechin/anaconda3/lib/python3.8/site-packages/projectq/ops/_gates.py:118: PendingDeprecationWarning: the matrix subclass is not the recommended way to represent matrices or deal with linear algebra (see https://docs.scipy.org/doc/numpy/user/numpy-for-matlab-users.html).

pytest初始化配置文件在上一节的测试结果中，我们发现有非常多的测试告警。假如我们确认这些告警信息可以忽略，那么我们可以通过在指令中配置忽略告警信息，或者直接使用这里介绍的pytest.ini来忽略相应的告警信息：
# pytest.ini[pytest]filterwarnings =ignore::PendingDeprecationWarning在当前目录下的ini配置文件中，我们添加了PendingDeprecationWarning作为忽略项，然后我们再回头看一下上述用例的测试结果：
[dechin@dechin-manjaro pytest]$ py.test=========================================== test session starts ============================================platform linux -- Python 3.8.5, pytest-6.2.2, py-1.9.0, pluggy-0.13.1rootdir: /home/dechin/projects/2021-python/pytest, configfile: pytest.iniplugins: cov-2.11.1, metadata-1.11.0, html-3.1.1collected 1 itemtest_random_number.py .[100%]============================================ 1 passed in 0.50s =============================================这里返回的结果中就没有告警信息了。
pytest生成html格式报告为了更好的展现测试的结果，这里我们需要先安装一个组件pytest-html：
