:::danger[Deprecated] The @nx/vite:test executor is deprecated. Please use @nx/vitest:test instead. This executor will be removed in Nx 23.

project.json:

json

//...
"my-app": {
    "targets": {
        //...
        "test": {
            "executor": "@nx/vite:test",
            //...
            //...
            "options": {
                "config": "apps/my-app/vite.config.ts"
            }
            //...
        }
    }
}

bash

nx test my-app

Examples

Running in watch mode

To run testing in watch mode, you can create a new configuration within your test target, and have watch set to true. For example:

json

"my-app": {
    "targets": {
        //...
        "test": {
            "executor": "@nx/vite:test",
            //...
            //...
            "options": {
                "config": "apps/my-app/vite.config.ts"
            },
            "configurations": {
                "watch": {
                    "watch": true
                }
            }
        }
    }
}

And then run nx run my-app:test:watch.

Alternatively, you can just run the default test target with the --watch flag preset, like so:

bash

nx run my-app:test --watch

Updating snapshots

Whenever a test fails because of an outdated snapshot, you can tell vitest to update them with the following:

bash

nx run my-app:test -u
