[@Banksy_said_hi]

This instruction is marvelous

[@EatTheBlocks]

Thanks!

[@GajeshSNaik]

Can I use remix to test smart contract?

[@EatTheBlocks]

I think so but I Truffle is more suited for testing

Indeed! Truffle seems not intuitive at the beginning but, as you get more experience, you realize that it makes your life easier as developer.

How do you pass in things like Msg.sender and Msg,value into your tests?

[@EatTheBlocks]

you can customize web3 transactions like this: web3.methods.foo(/*args here*/).send({from: /*address here*/, value: /* amount of ether sent */})

[@0f0crypto]

I followed the exact steps (up to ~9:00), but I get an error right away that the contract has not been deployed to the network ... so clearly there are some steps missing ... :(

[@JunPrg]

Awesome... Thank you so much

[@EatTheBlocks]

Most welcome 😊

[@auroraiiit5765]

at @22.41 how can we explicitly send 10 as uint parameter for the add function in the contract?

[@cryptotester5042]

Have you got an example on how to test a payable function with parameters?

[@theemacsen1518]

What are the vim plugins you use for Solidity?

[@EatTheBlocks]

this one: github.com/TovarishFin/vim-solidity (its forked from an older plugin that is abandoned)

[@theemacsen1518]

@@EatTheBlocks Thank you

[@rachelblack6407]

Im curious, so the contract is only re-deployed after every contract block in the test file, not after each time an instance is created and deployed with contract.deploy()?

[@EatTheBlocks]

The migration script is re-executed after each contract() block. But you can also manually deploy more contract instances with the deploy() method

thank u

When ever I am running following test : 1. Should NOT update a non-existing user 2. Should destroy an existing user 3. Should NOT destroy a non-existing user. all these test fail and give this error: AssertionError: Unspecified AssertionError please help how to solve this

[@EatTheBlocks]

Hey, thanks for reporting an error. However, Its impossible to help you with so little info. Please ask for help in the eattheblocks forum with the required info, as explained here: forum.eattheblocks.com/t/how-to-ask-for-help/62/2

[@leykunejigu7477]

Thank you for this awesome Tutorial. One question I got is, wouldn't it be better to define a function that returns crud.read() in the describe(contract) block and use it in the It blocks to avoid duplication.

[@eyalhochstadt3878]

I am trying to use the toNumber method, but get the result saying toNumber is not a function.
