I am using visual studio code and truffle and would like to easily debug my JavaScript tests.
A similar question has been asked here: how can I run a truffle test in a debugger?. This has been wrongly marked as a duplicated and not been released.

This similar answer, using truffle-core, worked for me: ethereum.stackexchange.com/a/41096/3708– SvanteApr 24, 2018 at 11:24

Add the following to your configurations in launch.json:
"configurations": [
{
"name": "run tests",
"type": "node",
"request": "launch",
"program": "${workspaceRoot}/node_modules/truffle/build/cli.bundled.js",
"args": ["test"],
"cwd": "${workspaceRoot}",
"outFiles": [
"${workspaceRoot}/test/**/*"
],
}
]
You will need to adjust the program property to match the path of your installed truffle if you have installed truffle globally.

You may want to add the network (configured in
truffle-config.js) to the arguments, like, assuming you called your networkdevelop:"args": ["test", "--network", "develop"],Also, you can just use the truffle executable instead ofcli.bundled.jsin the "program" section; I have found it runningwhich trufflefrom shell.– FantaJul 17, 2021 at 10:33
Clearly, if you have installed truffle globally (npm install -g truffle), you will need to provide the full path of that directory e.g.:
"program": "/usr/local/lib/node_modules/truffle/build/cli.bundled.js"
