Debugging in Foundry and Forge: Techniques for Solidity Developers

In this video, I walk through four essential debugging techniques in Foundry and Forge, as outlined in my YouTube video. These techniques include:

1. Verbose Test Output
2. Foundry Interactive Debugging
3. Printf Debugging
4. Event Logging

1. Verbose Test Output

Verbose test output is …

I found the discussion of "Dancing Cells" in Don Knuth's latest lecture (2023) extremely relevant to blockchain programming.

The reason is this method of memory allocation is very similar to the method required to organize data as a set in Solidity. See here

Here is a example implementation of some …

mocking calls to specific addresses in solidity

Mocking a specific address signature in Solidity is useful for simulating expected behavior from an existing address or instance of a contract. In mock testing dependencies are replaced with simulated implementations to isolate the behavior of the funtion under test.

Proxy contracts that …
