OSS License compatibility question
There’s some possible confusion on the license of your repository when you combine other open-source code. 

The module `tests/libs/mock.py` claims its license as **the BSD License**. However, the license of your whole project is shown as **the MIT license** in LICENSE, i.e., **less strict** than the BSD License on license terms, which has impacted the whole license compatibility in your repository and may bring legal and financial risks.

You can select another proper license for your repository, or write a custom license with license exceptions if some license terms couldn’t be summed up consistently
