what are the types of testing that can be done on a smart contract in the ton-contract-executor? And what are its limitations?

You want to use emulator, it's newer and has more functions. But basically you can check what messages will be sent from contract

Ok, well let me repeat the question then for emulator. What type of tests can be run and what are its limitations? Also for the test themselves are those typically typescript?

I've described basic outline. You make message and check what it will do to contract state. You can check examples in getgems contracts repository.

Emulator will do the same and a little bit more.

Will you update your ton lite client fork to support newer version of ton js?

it's already updated to use ton-core

whats some good test examples to look at in getgems contract repo?

idk, look at all of them, it's not that many

when I look at the top-level dependencies I don't see emulator there .. "dependencies": {
"@ton.org/func-js": "^0.1.3",
"@types/uuid": "^8.3.4",
"bn.js": "^5.2.1",
"chai": "^4.3.6",
"mocha": "^10.0.0",
"ton": "^11.18.2",
"ton-compiler": "^1.0.0",
"ton-contract-executor": "^0.5.2",
"uuid": "^8.3.2"
}

is it included via "ton": "^11.18.2"?

may be this https://github.com/ton-community/tx-emulator

yes thats the one

after const client = new LiteClient({ engine }); how can i know when client is ready to query? it shows engine closed error. if i query something as soon as instantiated

no idea

🤔

just wait a bit
