| | | npm run test -- --watch |

| | | > NOTE: You may see an `ENOSPC` error on Linux systems like the following: |
|---|
| | | ```bash |
|---|
| | | ERROR jest exited with code 1. |
|---|
| | | npm ERR! code ELIFECYCLE |
|---|
| | | npm ERR! errno 1 |
|---|
| | | npm ERR! todolist-fe@1.0.0 test: `vue-cli-service test "--watch"` |
|---|
| | | npm ERR! Exit status 1 |
|---|
| | | ``` |
|---|
| | | To fix this error, run the following command: |
|---|
| | | ```bash |
|---|
| | | echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p |
|---|
| | | ``` |
|---|
| | | |
|---|
| | | 3. All the tests should be passing when we begin. If `No tests found related to files changed since last commit` is on show; hit `a` on the terminal to re-run `all` tests. |
