test: enable turborepo caching for deterministic test tasks

[Harsh16gupta]

Fixes #1825

Removes "cache": false from test, test:unit, and test:integration
to allow Turborepo to cache successful runs.

test:update and test:integration:update keep "cache": false since
they mutate snapshot files and must always run.

Result:

---

npx turbo run test:unit
1st run

2nd run

---

npx turbo run test:integration
1st run

2nd run

---

npx turbo run test
1st run

2nd run

Summary by CodeRabbit

• Chores
  • Simplified build pipeline configuration for test steps by removing explicit cache settings and relying on default configurations. This streamlines the setup while maintaining test execution functionality.

What reviewer looks at during PR review

The following are ideal points maintainers look for during review. Reviewing these points yourself beforehand can help streamline the review process and reduce time to merge.

1. PR Title: Use a concise title that follows our Conventional Commits guidelines and clearly summarizes the change using imperative mood (it means spoken or written as if giving a command or instruction, like "add new helper for listing operations")

   Note - In Generator, prepend feat: or fix: in PR title only when PATCH/MINOR release must be triggered.

2. PR Description: Clearly explain the issue being solved, summarize the changes made, and mention the related issue.

   Note - In Generator, we use Maintainers Work board to track progress. Ensure the PR Description includes Resolves #<issue-number> or Fixes #<issue-number> this will automatically close the linked issue when the PR is merged and helps automate the maintainers workflow.

3. Documentation: Update the relevant Generator documentation to accurately reflect the changes introduced in the PR, ensuring users and contributors have up-to-date guidance.

4. Comments and JSDoc: Write clear and consistent JSDoc comments for functions, including parameter types, return values, and error conditions, so others can easily understand and use the code.

5. DRY Code: Ensure the code follows the Don't Repeat Yourself principle. Look out for duplicate logic that can be reused.

6. Test Coverage: Ensure the new code is well-tested with meaningful test cases that pass consistently and cover all relevant edge cases.

7. Commit History: Contributors should avoid force-pushing as much as possible. It makes it harder to track incremental changes and review the latest updates.

8. Template Design Principles Alignment: While reviewing template-related changes in the packages/ directory, ensure they align with the Assumptions and Principles. If any principle feels outdated or no longer applicable, start a discussion these principles are meant to evolve with the project.

9. Reduce Scope When Needed: If an issue or PR feels too large or complex, consider splitting it and creating follow-up issues. Smaller, focused PRs are easier to review and merge.

10. Bot Comments: As reviewers, check that contributors have appropriately addressed comments or suggestions made by automated bots. If there are bot comments the reviewer disagrees with, react to them or mark them as resolved, so the review history remains clear and accurate.

📝 Walkthrough

Walkthrough

The pull request modifies turbo.json to remove explicit cache: false settings from test, test:unit, and test:integration pipeline tasks. These tasks are now defined with empty objects, enabling them to use default caching behavior instead of forcing re-execution on every CI run.

Changes

Cohort / File(s)	Summary
Turborepo Configuration turbo.json	Removed explicit cache: false from test, test:unit, and test:integration tasks; these tasks now use default caching behavior while retaining their dependsOn configurations.

turbo.json (1)

13-18: Remote caching required for CI benefit

The demonstrated speedups are from the local filesystem cache. Turborepo's caching results in significant time savings when working locally — and is even more powerful when Remote Caching is enabled, sharing a cache among your entire team and CI. If you run the same task on a different machine that is also authenticated to your Remote Cache, it will hit cache the first time it runs the task.

CI agents start with cold local caches on each run, so enabling cache: true here has no effect on CI unless a remote cache (Vercel Remote Cache or a self-hosted provider) is also configured and authenticated in the CI workflow. Verify that the CI pipeline is wired to a remote cache backend, or the improvement will be local-only.
