Hey @ippy1997 try and increase the timeout value and see if it works. Try 500000

[othaime-en]

Could you please push your code to github and leave a link here. I'll look into it.

Hey @ippy1997 I've fixed a few errors you had in your test code and pushed it to github. Checkout the PR I've made to see the specific changes

Thanks a lot @othaime-en , would you kindly explain what was the issue with the code?

[othaime-en]

There were several errors.

1. reject(e) was supposed to be reject(error) because you were catching error here } catch (error) { not e
2. Here, const winnerStartingBalace = await accounts[1].getBalance()you were checking the balance ofaccount[1]which was wrong because the winner account wasaccount[2]so I changed it toconst winnerStartingBalace = await accounts[2].getBalance()`
3. In this line assert.equal(endingTimeStamp > startingTimeStamp) there was an error too because if you use assert.equal you shouldn't use operators inside the test. Here you were using > which would naturally throw an error. So I fixed it by removing .equal and changing the line to assert(endingTimeStamp > startingTimeStamp)

raffle.once("WinnerPicked", async () => {
                          console.log("Found the event")

The above console.log does not show up, which signifies our event listener for the winner being picked not occurring within the specified timeframe; this is why it leads to a time-out and not either a reject or a resolve.

Firstly, increase timeout to 5mins; if it still persists, you can diagnose the logic to account for the above.

got the same error after increasing the time

What can i do to fix this issue?

[Benrockiee]

Change your config file settings to goerli and try again, Rinkeby isnt helping much these days..

[jorgect207]

bro i got the same problem can you solutionate the problem?

[ippy1997]

@jorgect207 can you make a discussion and post your code so we can see whats the issue

[jorgect207]

i did but no one answer me :(

[ippy1997]

@jorgect207 can you share the link to that discussion?
