@Kmaschta maybe you can help me.
How can I test my little change? Any idea?

This package doesn't have unit tests. Yet!
We use jest for unit tests. It is already configured and you just have to run it with make test-unit-watch.
To test this package, you have to create a new file index.spec.js next to the index.js you edited.
There is a lot of these files, you can take them as examples.

Data providers like ra-data-simple-rest are basically a function which takes an httpClient and return a closure containing a big switch to build a request.

For your case, in order to test your change, you'll have to:

• mock the HTTP client
• call the data provider with the correct fixtures simpleRestProvider('url', mockedHttpClient)(UPDATE_MANY, ...)
• test that mocked HTTP client is correctly called with the correct arguments, including the method PUT

Hi! Could it be configurable to use PUT or PATCH?

As explained in #2372, this is not just a fix, it's a potential BC break. That being said, I'm willing to accept it on a minor release since it's only a BC break for people who replicated (imperfectly) the API of JSONRestServer instead of using their lib.

However, this needs to be done on the next branch rather than on master - even a minor BC beak is a no-go for a bugfix release. Can you please rebase on next?
