[PROPOSAL] End to end testing for your decentralized application

[yehia67]

• Content is: [x] Coding tutorial [ ] Informational content [ ] Other (describe)

• Which blockchain protocol is this about?: multichain

• Description (two or three phrases describing what is it about):

• Introduction: the difference between a unit test, integration test, and end-to-end testing.

• Testing with Foundry

• Add unit test using Test smart contract

• Integrate testing using Jest

• Fuzz Testing on Foundry.

• end to end testing with Cypress and Synpress(testing automation tool for Metamask wallet)

• Smart contract to deposit tokens with the "approve" transaction and ERC721 with the "signature."

• A form to deposit using React.

• Test scenario when the user approves some tokens and deposits them inside a staking pool.

• Test scenario when the user signs a message to deposit an NFT. (Explain how to test personal wallet signatures)

A little more breakdown please.

Specifically,

1. This is a DAPP testing tutorial, right? Will you be including testing for smart contract?

2. Which framework will you be using to write the smart contract? We prefer Foundry, but Hardhat also works.

3. Can you include a section where you explain signature signing a little bit?

1. Tutorial to test smart contracts and the frontend app, I am going to add unit testing and integration testing for the smart contract, and the end-to-end testing will be done by an automation tool(Synpress) from the frontend app
2. I prefer Foundry, too, because doing tests with solidity is much more efficient. If you are interested in Foundry, I will also add some topics related to testing with the foundry framework (e.g., fuzzy testing, smartContractTest.sol ...etc.)
3. Testing signatures is challenging because it passes the unit testing quickly, but sometimes it only works on the front end for other external reasons. for example a) User passed the signature validation time b) User use Ledger wallet, which produces a different personal signature So it is better to test signatures with the signing wallet with an automation tool like Synpress.

I updated the topics @Genesis3800.

Approving this. Looking forward to seeing your drafts.
