Jest can be configured in many ways, but primarily you'll need to at least have the jestConfig options
|
|
|
|
```json
|
|
"test": {
|
|
"executor": "@nx/jest:jest",
|
|
"options": {
|
|
"jestConfig": "libs/my-lib/jest.config.ts"
|
|
}
|
|
}
|
|
```
|
|
|
|
It is also helpful to have `passWithNoTests: true` set so your project doesn't fail testing while tests are still being added.
|
|
|
|
```json
|
|
"test": {
|
|
"executor": "@nx/jest:jest",
|
|
"options": {
|
|
"jestConfig": "libs/my-lib/jest.config.ts",
|
|
"passWithNoTests": true
|
|
}
|
|
}
|
|
```
|
|
|
|
### Snapshots
|
|
|
|
Update snapshots running with `--update-snapshot` or `-u` for short.
|
|
|
|
```bash
|
|
nx test my-project -u
|
|
```
|
|
|
|
Other times you might not want to allow updating snapshots such as in CI.
|
|
Adding a _ci_ configuration is helpful for adding this behavior.
|
|
|
|
```json
|
|
"test": {
|
|
"executor": "@nx/jest:jest",
|
|
"options": {
|
|
"jestConfig": "libs/my-lib/jest.config.ts",
|
|
"passWithNoTests": true
|
|
},
|
|
"configurations": {
|
|
"ci": {
|
|
"ci": true
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
```bash
|
|
nx affected --target=test
|
|
```
|
