How do I debug a failing test without enabling stop on "all exceptions?"

Environment

node -v: v10.12.0
npm -v: 6.9.0
npm ls jest: jest@23.5.0
your vscode-jest settings if customized:
- jest.pathToJest? blank
- jest.pathToConfig? blank
Operating system: macOS 10.14.5

Prerequisite

are you able to run jest test from command line? yes
how do you run your tests from command line? (for example: npm run test or node_modules/.bin/jest) copy-paste the line executed by vscode-jest:

cd /Users/ec/Sync/Code/excmd ; env CI=vscode-jest-tests /Users/ec/.nodenv/shims/node --inspect-brk=14995 node_modules/jest/bin/jest.js --runInBand parser.test.js --testNamePattern "parses a single command"

Relevant Debug Info

The only line in the Inspector console that appears to be jest-related:

spawning process with command=/Users/ec/Sync/Code/excmd/node_modules/.bin/jest, args=--json,--useStderr,--outputFile,/var/folders/xt/wm01x2h50nv993t_csb1t5qm0000gn/T/jest_runner.json,--watch,--no-color

(Unrelatedly: Every other output appears to be self-annotated by the relevant plugin with its' plugin-name; maybe add [jest] … to your log-lines?)

Here's my launch.json configuration:

{
   "type": "node",
   "name": "vscode-jest-tests",
   "request": "launch",
   "args": ["--runInBand"],
   "cwd": "${workspaceFolder}",
   "console": "integratedTerminal",
   "internalConsoleOptions": "neverOpen",
   "program": "${workspaceFolder}/node_modules/jest/bin/jest.js"
}

Expected Behavior

Clicking the ‘debug’ annotation on a broken test would launch a debugger, which then would stop executing at that test, or possibly on the exception generated during that test, even with “all exceptions”

Actual Behavior

I must be missing something, because without enabling stopping on caught exceptions, I just see the tests running in the debugger output, and then the process exits … and if I do turn on stop on caught exceptions (“all exceptions” in VScode), which can't be necessary (!?), then the debugger stops on a billion low-level Node control-flow constructs involving module-loading within Jest itself.

I'm assuming this is user-error, but I can't figure out what I've configured incorrectly. How do I simply debug one failing test?
