• Payement tests workings with refactor
• Implements wallets methods (getWalletData & deletePaymentMean)
• TU
• Javadoc

Feedback appreciated !

Great work so far, @Jydett!

Couple remarks up until now

• SIPS 1.0 is EOL and only ever sold in FR. I’d propose not to use any sips 2.0 references, as this will cause unneeded confusion

• ING Home’Pay is discontinued by ING and will shortly be removed from SIPS

[Jydett]

Ok @CrlH thx for the feedback.
I'll remove the SIPS 2.0 references and ING HomePay.

A couple a unit tests and documentations and this should be ready to review :D

On a side note are you interested to add github actions to this project ? (this could be done in another PR if you are interested)

[Jydett]

This si worth noting that this could be a major version since some imports and names changed

[Jydett]

I've updated the readme without changing the version number since I'm not sure how you want to bump the lib version with this PR
