  • is there an easy (python like way) to do mocks? | 2021-10-16
    I discovered this lib a few days ago. it allows you to monkey patch entire functions, replacing them by whatever you want. Perfect for mocking. It's simple to use. The program is hard patching the code using assembly to replace the function address at runtime. You should not use this lib out of your tests since it's absolutely not safe. It's only compatible with linux and windows. But it works great!

    Either the author is confused or has decided that he doesn't want to maintain an hack. Anyway license is pretty clear.

    There was an HN thread[2] when it was released.
