Summary

This is a test PR to trigger CI and investigate the flaky test failure in spec/stimulus/turbo_spec.rb:20.

Issue

The test "shows inline form when Inline Form link is clicked" is failing intermittently with:

expected `#<Capybara::Session>.has_css?(".form-inline")` to be truthy, got false 

This appears to be a timing/race condition where the .form-inline CSS class isn't appearing quickly enough after clicking the link.

Action

Re-running CI to see if this is a flaky test or a real regression.

This is a test commit to re-run CI and check if the failing spec/stimulus/turbo_spec.rb:20 test passes on re-run. The test failure appears to be a timing issue with the Turbo/Stimulus interaction where the .form-inline CSS class isn't appearing quickly enough. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

PR Review: Test Commit to Trigger CI

Overview

This PR is a test commit designed to re-run CI and investigate the flaky test in spec/stimulus/turbo_spec.rb:20. The PR contains no code changes, which is appropriate for its stated purpose.

Analysis

Purpose Assessment: ✅ Good

  • The PR correctly identifies this as a test commit to investigate intermittent test failures
  • The approach of re-running CI to verify if the test is flaky is reasonable

Issue Identified: ⚠️ Timing/Race Condition
After reviewing the test and related code, the flaky test failure appears to be a legitimate timing issue:

Root Cause Analysis:

  1. Test Location: spec/stimulus/turbo_spec.rb:20-23

    it "shows inline form when Inline Form link is clicked" do click_link("Inline Form") expect(page).to have_css(".form-inline") end
  2. The Problem:

    • The test clicks "Inline Form" link which triggers a Turbo Frame request to /comments/inline_form
    • The controller (app/controllers/comments_controller.rb:95-100) renders the partial comments/turbo/_inline_form.html.erb
    • The partial has the CSS class on line 7: class: "form-inline flex flex-col lg:flex-row flex-wrap gap-4"
    • The test expects the .form-inline class to be present immediately after clicking
    • No explicit wait is configured - the test relies on Capybara's default wait time
  3. Configuration Issues:

    • spec/rails_helper.rb doesn't configure Capybara.default_max_wait_time
    • Capybara's default wait time is 2 seconds, which may be insufficient under CI load
    • No retry logic or explicit waits are used for Turbo Frame loading

Recommendations

1. Fix the Flaky Test (Priority: High)

Add explicit wait configuration in spec/rails_helper.rb:

# Around line 78, add: Capybara.default_max_wait_time = 5 # Increase from default 2 seconds

2. Alternative: Add Test-Specific Wait (Priority: Medium)

If the global timeout is too aggressive, add a test-specific wait:

it "shows inline form when Inline Form link is clicked" do click_link("Inline Form") expect(page).to have_css(".form-inline", wait: 5) end

3. Consider Turbo-Specific Helpers (Priority: Low)

For better Turbo Frame testing, consider waiting for the frame to finish loading:

it "shows inline form when Inline Form link is clicked" do click_link("Inline Form") # Wait for turbo frame to finish loading expect(page).to have_selector('turbo-frame[id="form_tabs"]:not([busy])', visible: false) expect(page).to have_css(".form-inline") end

4. Review Other Similar Tests (Priority: Medium)

The other tab-switching tests (lines 15-18, 25-29) may have similar issues but might be passing due to:

  • have_no_css assertions being more lenient
  • Different timing characteristics

Consider applying consistent wait strategies across all tab-switching tests.

Additional Observations

Test Quality:

  • ✅ Tests use appropriate Capybara matchers
  • ✅ Tests are well-organized and descriptive
  • ⚠️ Tests lack explicit waits for asynchronous operations (Turbo Frames)

Code Quality (Related Files):

  • ✅ Controller is clean and follows Rails conventions
  • ✅ Stimulus controller properly handles form validation and ActionCable
  • ✅ ERB templates use proper Turbo Frame tags
  • ⚠️ No console error handling in Stimulus controller (non-critical)

Security: ✅ No concerns

  • Strong parameters properly configured (comment_params)
  • No XSS vulnerabilities identified

Performance: ✅ No concerns for this test commit

Test Coverage: ⚠️ The flaky test reduces confidence in CI

  • Once fixed, coverage should be adequate for the Turbo/Stimulus integration

Verdict

This PR successfully serves its purpose of triggering CI to investigate the flaky test. However, the underlying issue is a real timing/race condition that should be fixed rather than just re-running CI and hoping it passes.

Suggested Next Steps:

  1. Close this PR (or merge if it passes, since there are no code changes)
  2. Create a new PR implementing one of the recommended fixes above
  3. Monitor the new PR's CI runs to verify the fix resolves the flakiness
