`jest` is the testing framework itself, and `ts-jest` is just a simple function to make running TypeScript tests a little easier.
### Configure Jest
Jest's configuration lives in `package.json`, so let's open it up and add the following code:
```json
"jest": {
"globals": {
"__TS_CONFIG__": "tsconfig.json"
},
"moduleFileExtensions": [
"ts",
"js"
],
"transform": {
"^.+\\.(ts)$": "./node_modules/ts-jest/preprocessor.js"
},
"testMatch": [
"**/test/**/*.test.(ts|js)"
],
"testEnvironment": "node"
},
Jest's configuration lives in `jest.config.js`, so let's open it up and add the following code:
```js
module.exports = {
globals: {
'ts-jest': {
tsConfigFile: 'tsconfig.json'
}
},
moduleFileExtensions: [
'ts',
'js'
],
transform: {
'^.+\\.(ts|tsx)$': './node_modules/ts-jest/preprocessor.js'
},
testMatch: [
'**/test/**/*.test.(ts|js)'
],
testEnvironment: 'node'
};
```
Basically we are telling Jest that we want it to consume all files that match the pattern `"**/test/**/*.test.(ts|js)"` (all `.test.ts`/`.test.js` files in the `test` folder), but we want to preprocess the `.ts` files first.
This preprocess step is very flexible, but in our case, we just want to compile our TypeScript to JavaScript using our `tsconfig.json`.
