Problem running discovery test

has anyone experienced a similar issue?

hey @berlin ,

I’m not getting that error. I’m on node v10.16 too. I wonder, did you perform these steps prior to discovery test?

discovery start
discovery compile
discovery migrate

I’m wondering if an exception is getting thrown because the network’s not running or the contracts haven’t been deployed.

I’m working with a fresh project after doing a discovery init … that might not be your case?

I’m able to run the tests though I had to modify the migrations/2_deploy_contract.js script to reflect where I’m running it from (the project directory). The boilerplate code in there was trying to write the secret contract address to a .txt file under ../test/simple_addition.txt. That file is used by the tests. If you run into that issue, either run the migration from within the migrations folder or change the deploy script to write to test/simple_addition.txt.

I’d reiterate what @laura said – and add that while we did have some problem with specific node versions, it doesn’t look like that is the issue with your setup. cc @adi to have a look when possible!

I did discovery start
discovery compile works fine.

discovery migrate return errors. as you can see the node version is v10.16.0.

iscovery migrate

Can you post the output of discovery start?

when you ran discovery init did you specify HW for SGX hardware mode or SW for software mode? I believe the EnigmaSimulation.json is for SW mode and since it can’t be found I’m thinking it wasn’t generated due to the mode chosen during init.

berlin · July 31, 2019, 6:28pm

I specified sw as indicated in the instruction.

laura · July 31, 2019, 6:48pm

I couldn’t see the entire log of your post for the output of discovery start but at a certain point the command displays:

Compiling your contracts ...

One of the lines should say:
Compiling ./contracts/EnigmaSimulation.sol

That’s what causes the EnigmaSimulation.json to get generated under the build/enigma_contracts dir.

Can you confirm that the json file is missing from that directory? If it is, can you do another discovery start and post the relevant output here, where the contract compiling messages are displayed?

berlin · July 31, 2019, 7:07pm

I resolved the issue.

I reinitialized discovery to get the the ./contracts/EnigmaSimulation.sol.
The location of the file ‘millionaires_problem.txt’ which contains the contact address needs to be changes in deployment and the test scripts.

laura · July 31, 2019, 7:11pm

Awesome!

Yes, I saw that issue as well. I’ll relay that to the team.

Thanks, @berlin!

I had the same initial problem (await is only valid in async function) then I realized the code to add in 2_deploy_contracts.js must be added inside of module.exports = async function(deployer, network, accounts) {}

guix · August 1, 2019, 4:58pm

If you launch discovery migrate or discovery test from the root folder, you must edit 2_deploy_contracts.js and in the function deploySecretContracts, replace '../test' by './test' in writeFile

For the record, the above issue has been addressed in Fixpath by lacabra · Pull Request #6 · scrtlabs/discovery-cli · GitHub, and a new version 0.0.20 has been released that includes the above changes. It will be fixed in any future installations.
