eshfaq-ux · 2025-10-02T10:24:10Z

This PR was automatically generated by the AI Test Case Generator.

Summary by CodeRabbit

Tests
- Added automated tests to validate sticky navbar behavior on scroll, ensuring it reveals correctly after passing the threshold.
- Simulates a browser environment and user scrolling to verify initial hidden state and visible state transitions.
- Mocks external dependencies to isolate behavior and improve test reliability.
- Enhances confidence in navigation consistency and helps prevent regressions affecting header visibility during scrolling.

Walkthrough

Adds a new Jest test generated.test.js to validate sticky navbar behavior on scroll within a JSDOM environment. Mocks WOW.js and the owlCarousel jQuery plugin, injects and executes main.js, simulates scroll events, and asserts the navbar’s CSS top transitions from -100px to 0px when scrollTop exceeds 300px.

Changes

Cohort / File(s)	Summary
Tests: Sticky navbar behavior `generated.test.js`	New Jest test that mocks WOW.js and owlCarousel, sets up JSDOM with a sticky navbar, loads and runs main.js, simulates scroll from 0 to >300px, and asserts CSS top changes from -100px to 0px.

Poem

I hop through tests with whiskers keen,
A navbar sticks—now clearly seen.
From minus heights to zero’s line,
At three-oh-one, the scroll’s just fine.
With mocks and DOM, I tap-tap-tap—
All green carrots in my CI lap. 🥕✅

⚠️ Potential issue | 🔴 Critical

Remove Markdown fences from source file.

The test file is wrapped in Markdown code fences (```javascript … ```), so the emitted file is not valid JavaScript and fails to parse (Biome flags cascading syntax errors). Drop the fence lines so the file starts directly with the JSDOM pragma.

In generated.test.js around lines 1 to 78, the file is wrapped in Markdown code fences (```javascript ... ```), which makes it invalid JS; remove the opening ```javascript line and the closing ``` line so the file begins with the JSDOM pragma comment and contains only plain JavaScript; ensure there are no leftover fence characters or blank lines before the pragma.

⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

Validate main.js lookup path.

The test reads ../../source code/js/main.js, but the repository appears to keep assets under different directories (commonly source/js or assets/js). Please confirm the actual location so the test doesn't throw ENOENT.

Run this script from the repo root to see where main.js lives:

🏁 Script executed:

#!/bin/bash set -euo pipefail fd -H --type f --max-results 20 main.js

Length of output: 22

🏁 Script executed:

#!/bin/bash set -euo pipefail test_file=$(fd -H --type f generated.test.js) echo "Test file: $test_file" test_dir=$(dirname "$test_file") echo "Checking resolution from $test_dir:" target="$test_dir/../../source code/js/main.js" if [[ -f "$target" ]]; then echo "Exists at:" $(realpath "$target") else echo "Not found at $target" fi

Length of output: 100

Fix main.js lookup path. In generated.test.js the code calls

path.resolve(__dirname, '../../source code/js/main.js')

but main.js lives at source code/js/main.js relative to the repo root. Update to:

path.resolve(__dirname, 'source code/js/main.js')

🤖 Prompt for AI Agents

In generated.test.js around lines 27 to 29, the path.resolve call incorrectly uses '../../source code/js/main.js' which points outside the repo root; update the lookup to use 'source code/js/main.js' relative to __dirname so the code reads path.resolve(__dirname, 'source code/js/main.js') and keep the fs.readFileSync usage as-is to read that resolved path.
