Unit Tests Generator Open Source – Your Opinion

I'm thinking about developing a new open source project and want to check if people would like to use it before I do.

The idea is to record each function call, input and output on runtime and offer developers to add unit tests within a mouse click, based on the intercepted data.

So you are a developer, and running your software in order to manually test it, the open source will then intercept each called function, and filter the most interesting ones and offer those for you.

It will write the test code for you and let's say it will deal with input, output, mocks (not just simple functions) and assertions,

would it be something you would use? or at least try?
