Error running anchor tests on Solana
Overview
The issue you are facing is related to running tests on your Solana blockchain using the Anchor framework. Specifically, when trying to run a test using the anchor test
command, you are encountering an error that points to a file extension issue.
Step-by-step solution
- Check your file extensions
: Make sure your
.ts
files are compiled correctly and have the same file extensions as their corresponding Solana tests. Typically, Solana tests end with “.sol”.
- Update anchor command: Make sure you are using the correct anchor command to compile and run your test. The command is typically
anchor compile --test
. Replace
with the actual path to your test file.
- Check Solana’s Solhint configuration:
Solhint is a tool that helps you detect errors in your code. To configure Solhint for better error handling, follow these steps:
– Create a solhint.json
configuration file in the root directory of your project.
– In the solhint.json
file, specify the path to the solhint executable and configure the rules accordingly.
For example:
`json
{
"rules": ["
"path": "/usr/bin/solhint"
}
solhint.json
Compiling and running tests
: Once you have updated yourconfiguration, run the following command to compile and test your code:
hit
anchor compile --test /home/ahmed/development/your-x/tests/your-x.ts
- Verify that your tests are running correctly:
After running the compiled tests, verify that they are running correctly by checking the output or logs for errors related to TypeError: Unknown file extension “.ts”.
- Update Anchor - If the test build still fails, make sure your Solana node is up to date and the necessary packages are installed.
Troubleshooting
- Make sure you have installed the necessary dependencies in your project root directory.
- Check for conflicts between solhint rules and other tool configurations (e.g. npm or yarn).
- Check that your test files do not contain any syntax errors but still cause theTypeError`.
By following these steps, you should be able to resolve the error associated with building and running tests on your Solana blockchain using Anchor.
