stime的Python项目详细描述
模拟时间
对python的time包的测试（和部分）替换，用于完全受控的时间相关测试。
测试依赖于时间的函数总是很棘手，而且可能需要很长时间。为了节省时间并避免依赖于time.sleep()，这个包允许任意地快进时间。
它实现了stime.time()和stime.monotonic()函数。
Note: This package in not meant to replace
timein production! Only in testing environments!
用法
其思想是让您的代码在测试时使用stime.test()，而不是time.test()。
理想情况下，您要测试的代码是通过依赖注入接收时间源，如下面示例中的Timer类。
如果您正在测试的代码没有使用依赖注入，那么您很可能仍然可以在测试中重写time函数。这不太优雅，但可以是一个公平的权衡，以避免其测试套件依赖于time.sleep()。
一旦代码使用stime，就可以使用stime.reset()和stime.tick()：
stime.time()（或stime.monotonic()）的输出。
tick(n)：将当前时间增加n秒（例如1.3秒）reset(t)：（re-）将当前时间设置为时间戳t（例如1561120200）

- ①导入
stime，如果不是测试的话，您可以导入time。 - ②将当前时间设置为任何方便的时间…
- ③根据需要经常复位……
- ④方便时快进……
- ⑤或一次前进一秒！
开发
开始
（可选）为此项目创建虚拟环境并将其激活。
python -m venv timer_venv # assuming Python 3
. timer_venv/bin/activate
那就做你的事！
# run the example test suite: python test_timer.py # once you're done deactivate the virtual environment if you use one: deactivate
释放
# Install the latest setuptools and wheel (in a virtual environment eventually) pip install --upgrade setuptools wheel # Update the package version number and tag it: vim setup.py git tag -a 'v1.0.0' -m 'Initial release' git push origin master --tags # Build the distribution files make build # And upload them to PyPI make upload_to_pypi
