An issue with error 'Attempt to load a program that does not exist'

[Rinat Shigapov]

I have an issue when I try to test my pet project.

It looks like I'm loading some unexisting program.

Here is test output of trdelnik test

running 1 test
test test_id ... ok

I built trdelnik from current master

type trdelnik
trdelnik is hashed (/Users/rinatshigapov/workspace/evita/../trdelnik/target/debug/trdelnik)

I tried to add extra log messages to runtime/src/accounts.rs in solana checkout at v1.10.29 tag. I want to output which program_id is not found.

But I don't know how to see test-validator log messages.

solana --version
solana-cli 1.10.29 (src:devbuild; feat:1425680972)

Hi!
The problem might be that you're declaring a different program ID (6syjPkpJf6gT6JCaXvWVDfKk4vv29s16F7FTWB2t4XP5) than you're actually using in your test.
Changing your program ID to the public key of program_keypair(1) (Po1RaS8BEDbNcn5oXsFryAeQ6Wn8fvmE111DJaKCgPC) you're using in your test should hopefully solve this issue.

@antoninkriz , thank you for pointing this!

Indeed it fixes the problem.

I find it strange that I have to synchronise the declared id.

If I decide to test my program in another environment using another keypair do I have to change it again?

I think the default template for trdelnik test should look for the program keypair the same way as solana does - in the same directory as build artifacts.

Now it uses constant keypairs that do not work out of the box.

[Rinat Shigapov]

I noticed that a new key-pair subcommand and updated README.md have landed in master. Now it's more clear how to use test program keypairs.

Thank you!
