anchor: cli: Renaming program mod causes test to fail

Steps to reproduce

anchor init hello
anchor test
change the progrma’s main mod hello to mod fails_now_hello
anchor test

The test will throw Transaction simulation failed: Attempt to load a program that does not exist.

This is caused by the fact that there are two target/idl idls and only a single program.

@ezy I was able to get around this. I’m not sure what the underlying issue is, but I noticed that the solana-test-validator process was still running between tests (maybe there was an initially failed test that left it hanging…idk).

Checked if local chain was running ps au
killed local solana-test-validator process
Cleaned out the workspace cargo clean
Deleted node_modules rm -rf node_modules
Reinstalled node modules yarn install
Re-ran tests anchor test

My hunch is the issue has something to do with the hanging solana-test-validator process.

Ran into the same issue, then realized I missed the line that said Make sure to turn off the validator before you begin testing Anchor programs. so I was able to get it running by simply stopping the validator 😅

As @h4rkl mentioned, you can also run anchor test --skip-local-validator

@tomjohn1028 For me, the issue ended up being that my solana-test-validator was already running. Killing that process did the trick. Surprisingly the extremely thorough Solana dapp tutorial here didn’t mention making sure local Solana processes were stopped whilst testing. 🤔

I had similar problems here @ezy - did you try anchor test --skip-local-validator?

1. Checked if local chain was running `ps au`

2. killed local _solana-test-validator_ process

3. Cleaned out the workspace `cargo clean`

4. Deleted node_modules `rm -rf node_modules`

5. Reinstalled node modules `yarn install`

6. Re-ran tests `anchor test`
My hunch is the issue has something to do with the hanging solana-test-validator process.

When I turn off the solana-test-validator and run anchor test, I get this error: Unable to get recent blockhash. Test validator does not look started. Check .anchor/test-ledger/test-ledger-log.txt for errors. Consider increasing [test.startup_wait] in Anchor.toml.

It’s sorted now actually. I had to update my Program ID after the initial deploy.

Thanks @tomjohn1028, followed the instructions more closely and got it working.
