Once the **patch** is successfully applied, developer must run tests to validate the fix that was backported by running following tests, locally.

Unit tests

```
λ make test
```

Verify different type of MinIO deployments work

```
λ make verify
```

Verify if healing and replacing a drive works

```
λ make verify-healing
```

There have been many tools created before that have helped inspire its creation.

I have been avoiding the creation of a new framework for several years. First I tried to solve all the features covered by **FastAPI** using many different frameworks, plug-ins, and tools.

It includes ways to authenticate using a "third party".

That's what all the systems with "login with Facebook, Google, Twitter, GitHub" use underneath.

### OAuth 1

There was an OAuth 1, which is very different from OAuth2, and more complex, as it included direct specifications on how to encrypt the communication.

It is not very popular or used nowadays.
