Implement Unit Tests for Validator-CLI Commands

[kenny-io]

The validator-cli contains several important commands in the src/node-commands.ts file, but currently lacks comprehensive unit tests. Adding tests for these commands will significantly improve the reliability and maintainability of the CLI.

Proposed Solution

Implement unit tests for all the commands in the src/node-commands.ts file, covering various scenarios and edge cases.

Expected Outcome

After implementing your solution:

• All commands in src/node-commands.ts should have corresponding unit tests
• Test coverage should be high (aim for >80%)
• Tests should cover successful executions, error handling, and edge cases
• The codebase will be more reliable and easier to maintain
• Potential bugs will be caught before reaching production

Getting Started

• Fork the repository
• Clone your fork: git clone [your-fork-url]
• Create a new branch: git checkout -b feature/add-unit-tests
• Create a new test file: src/tests/node-commands.test.ts
• Implement unit tests for each command in src/node-commands.ts, including but not limited to:
  start,stop,status,info,stake,unstake,version,update,gui,clean
• Run tests and ensure they pass
• Commit your changes: git commit -m "Add unit tests for operator-cli commands"
• Push to your fork: git push origin feature/add-unit-tests
• Create a pull request

Mentorship

👋 @kenny-io
You dont have any test runner in your package.json, should we pick anything we like or do you have a preference ?
I see a "defaultRpcConfig" at the beginning of the file, do we need to be running the test along side a running node or can it be run completely standalone (e.g real unit tests)
It's gonna be a tricky business mocking the dependencies and the API/Promise calls. Do you have a reference for those endpoints that can provide fake data to plug into the tests?

Last question:
Can I run those tests against my Atomium node running on the testnet or is there a risk of breaking it / overloading it ?

@phy-chain I would recommend jest for the test as we are using it in other projects but its ultimately up to you as we are not currently enforcing particular one.

For the best outcome, I would recommend running the cli against a locally running shardeum node, not the live testnet. If you haven't set one up before, this documentation is very helpful

We don't yet have any endpoints that provides mock data (this could be a good issue/PR to come out of this one)
