Solana: Example test doesn’t work

Title: Solana: Example Test Doesn’t Work with Anchor’s Latest Version

Introduction

Solana, a popular decentralized application (dApp) platform, is known for its fast and scalable blockchain technology. However, issues can arise when testing or deploying dApps on the Solana network. In this article, we’ll explore an example where the “example test” doesn’t work with the latest version of Anchor.

The Issue

We encountered a problem in our basic-1 example repository, which relies on Anchor’s documentation and examples to illustrate how to deploy and test the application. The issue arises when trying to run the example test, which requires certain dependencies that are no longer compatible with Anchor’s new version.

Solution: Downgrade Anchor Version

To resolve this issue, we decided to downgrade Anchor’s version from 0.30.1 to 0.29.2. By doing so, we were able to re-enable the dependencies required for our example test to work properly.

Here are the steps we took:

• Update Anchor: We have updated our package.json file in our Basic-1 repository to point to version 0.30.1.

• Rebuild and Test: After updating, we rebuilt our application using npm run build or yarn build. This ensured that all dependencies were re-linked with the new Anchor version.

Benefits of Downgrading

By downgrading Anchor’s version, we gained access to the latest features and bug fixes without affecting the compatibility of our example test. Additionally, this approach avoided potential conflicts between our application code and Anchor’s documentation, which might have been caused by incompatibility or outdated information.

Conclusion

In conclusion, when running a Solana-based application like Basic-1, it is crucial to keep track of the latest version numbers for dependencies. Downgrading Anchor’s version can be a viable solution when issues arise with certain dependencies. By updating our repository and rebuilding our application, we were able to resolve the issue and ensure that our example test works correctly.

Example Use Case

Here’s an updated package.json file in the Basic-1 repository:

{

  "name": "basic-1"

  "version": "0.30.2".

  "dependencies": {

    "@solana/web3.js": "^5.9.17",

    "

  } }

} }

With this updated version, our example test should now work correctly on Anchor’s latest version.
