TypeScript with express, nodemon & jest --watch

I've got just set up just fine, I can run jest and my unit tests are run. I've also get tsc-watch keeping an eye on my changes and compiling when I run yarn dev the below script in package.json is triggered.

  "scripts": {
    "dev": "tsc-watch --project . --outDir ./dist --onSuccess \"nodemon ./dist/app.js\"",

Is there some way I can have jest constantly watching at the same time, so if I break a test as I'm coding it will tell me immediately?

My jest.config.js looks like

module.exports = {
    roots: ['<rootDir>/tests'],
    transform: {
      '^.+\\.tsx?$': 'ts-jest',
    testRegex: '(/tests/.*|(\\.|/)(test))\\.tsx?$',
    moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'json', 'node'],

and my tsconfig.js

    "compilerOptions": {
        "module": "commonjs",
        "esModuleInterop": true,
        "target": "es6",
        "noImplicitAny": true,
        "moduleResolution": "node",
        "sourceMap": true,
        "outDir": "dist",
        "baseUrl": ".",
        "paths": {
            "*": [
    "include": ["api/**/*"],
    "exclude": ["node_modules", "tests/**/*"]
