Pull request overview

This PR adds a Jest/Supertest test suite for the Task API, fixes multiple bugs discovered via testing, and implements the new PATCH /tasks/:id/assign feature with validation and documentation notes.

Changes:

• Added unit tests for taskService and integration tests for /tasks endpoints (including the new assign endpoint).
• Fixed status filtering to match exact statuses and prevented completeTask from overwriting priority.
• Added PATCH /tasks/:id/assign with request validation, and adjusted pagination parsing to allow page=0.

validateAssignTask assumes body is a non-null object and will throw if it’s called with undefined/null (e.g., when the request has no JSON body or a non-JSON Content-Type, req.body can be undefined). Consider defensively handling a falsy body (treat as {}) and returning a 400 validation message instead of letting the request fall into the 500 error handler.

Pagination defaults look inconsistent with the (now-supported) page=0 / zero-based paging model: when limit is provided without page (e.g. /tasks?limit=2), parsedPage becomes NaN and pageNum defaults to 1, which skips the first page (offset = page * limit). Consider defaulting pageNum to 0 when page is missing, or (if the API is intended to be 1-based) adjusting the service call to use (pageNum - 1) when computing the offset. Also consider rejecting negative page/limit values to avoid Array.slice's surprising behavior with negatives.

	const parsedPage = parseInt(page);
	const pageNum = isNaN(parsedPage) ? 1 : parsedPage;
	const parsedLimit = parseInt(limit);
	const limitNum = isNaN(parsedLimit) ? 10 : parsedLimit;
	const parsedPage = page === undefined ? 0 : parseInt(page, 10);
	const parsedLimit = limit === undefined ? 10 : parseInt(limit, 10);
	if (Number.isNaN(parsedPage) || parsedPage < 0) {
	return res.status(400).json({ error: 'page must be a non-negative integer' });
	}
	if (Number.isNaN(parsedLimit) || parsedLimit < 0) {
	return res.status(400).json({ error: 'limit must be a non-negative integer' });
	}
	const pageNum = parsedPage;
	const limitNum = parsedLimit;

The pasted coverage table appears internally inconsistent: it reports tasks.js (and taskService.js) at 100% lines/statements while also listing uncovered line numbers (e.g. tasks.js | ... | 21-23). If these line numbers are truly uncovered, the percentages should be <100; otherwise the uncovered-line column should be empty. Please re-run npm run coverage and update this snippet so the numbers match the actual output.
