Question

How do you debug Jest Tests ?

Answer 1

Run

node --debug-brk node_modules/.bin/jest

in your project directory. It should start the node process paused an listening (usually at port 5858) for a debugger. Visual Studio Code is an example of a nice graphical debugger for node.js that can be used to connect to the listening node process.
