Fixes #907

Describe the changes you have made in this PR -

Extended the unit test suite for RailwayRemoteOpsProvider in tests/remote/test_ops.py. This PR adds coverage for:

  • logs(): Verifying command construction for log streaming.
  • fetch_logs(): Verifying capturing and combining stdout/stderr output.
  • restart(): Verifying JSON parsing of the redeploy command.
  • Error handling for invalid JSON output and unexpected JSON shapes from the Railway CLI.

Code Understanding and AI Usage

Did you use AI assistance (ChatGPT, Claude, Copilot, etc.) to write any part of this code?

  • No, I wrote all the code myself
  • Yes, I used AI assistance (continue below)

If you used AI assistance:

  • I have reviewed every single line of the AI-generated code
  • I can explain the purpose and logic of each function/component I added
  • I have tested edge cases and understand how the code handles them
  • I have modified the AI output to follow this project's coding standards and conventions

Explain your implementation approach:

  • What problem does your code solve? It fixes the lack of test coverage for remote operations in the Railway provider, ensuring that changes to the CLI interaction logic are caught by CI.
  • Implementation: I used unittest.mock.patch to stub subprocess.run and shutil.which. This allows us to simulate the Railway CLI environment perfectly without actually requiring the tool to be installed.
  • Key Components: I introduced a reusable _Result class at the module level to standardize how we mock subprocess results. I specifically added tests for stderr-only output in logs and malformed JSON responses to handle Railway CLI edge cases robustly.

Checklist before requesting a review

  • I have added proper PR title and linked to the issue
  • I have performed a self-review of my code
  • I can explain the purpose of every function, class, and logic block I added
  • I understand why my changes work and have tested them thoroughly
  • I have considered potential edge cases and how my code handles them
  • If it is a core feature, I have added thorough tests
  • My code follows the project's style guidelines and conventions

Greptile Summary

This PR extends the unit test suite for RailwayRemoteOpsProvider by adding coverage for logs(), fetch_logs(), restart(), and JSON-parsing error paths. It also refactors the previously inline _Result helper class to module scope, which is a good DRY improvement shared across all tests.

Confidence Score: 5/5

Safe to merge — test-only changes with correct assertions and no impact on production code.

All new tests are logically correct and their assertions align precisely with the production implementation. The only finding is a P2 style suggestion about next() vs explicit list filtering for clearer failure messages.

No files require special attention.

Important Files Changed

Filename Overview
tests/remote/test_ops.py Adds 6 new test functions covering logs, fetch_logs, restart, and JSON error handling; refactors _Result helper to module scope. All assertions align correctly with the production implementation.
