Returning array of values

[Juan-cc]

Hi, I am trying to simulate a call to UniswapV2Router02.swapExactETHForTokens() (link)

That method returns a uint[], so I tried mocking that using: abi.rawEncode([ "uint[]" ], [ [1] ])

Here is the complete method mock definition:

await uniswapV2Router02.givenMethodReturn(
      uniswapEncorder.encodeRouterETHForTokens(),
      abi.rawEncode([ "uint[]" ], [ [1] ])
    );

Is it possible to encode an array of values?

Thanks!

Yes, this is possible. The way to do it should be:

const method = await mockedUniswap.contract.methods.swapExactETHForTokens(0, [], 0x00...00, 0).encodeABI();
const result = web3.eth.abi.encodeParameter("uint[]", [1,2,3])
await mock.givenMethonReturn(method, result)

It worked! Thanks @fleupold
