default environments:
default -> Invoke pytest to run automated tests
additional environments:
build -> Build the package in isolation according to PEP517, see https://github.com/pypa/build
clean -> Remove old distribution files and temporary build artifacts (./build and ./dist)
docs-> Invoke sphinx-build to build the docs
doctests-> Invoke sphinx-build to run doctests
linkcheck -> Check for broken links in the documentation
publish -> Publish the package you have been developing to a package index server. By default, it uses testpypi. If you really want to publish your package to be publicly accessible in PyPI, use the `-- --repository pypi` option.

# 往 pyproject.toml 中添加对boto3 的依赖并安装(add 还能从本地或 git 来安装依赖 ),
poetry add boto3
# 将依照 pyproject.toml 文件中定义安装相应的依赖到当前的 Python 虚拟环境中
# 比如在 /lib/python3.9/site-packages 目录中，安装好模块后也可让测试用例使用
poetry install

1.poetry build# 构建可安装的 *.whl 和 tar.gz 文件
2.poetry shell# 会根据定义在 pyproject.toml 文件中的依赖创建并使用虚拟环境
3.poetry run pytest# 运行使用 pytest 的测试用例，如 tests/test_sample.py
4.poetry run python -m unittest tests/sample_tests.py# 运行 unittest 测试用例
5.poetry export --without-hashes --output requirements.txt# 导出 requirements.txt 文件, --dev导出含 dev 的依赖，或者用 poetry export --without-hashes > requirements.txt
