Pull request overview

This PR aims to add JSDoc documentation throughout the codebase to improve code maintainability and developer experience. However, the changes include significant breaking modifications to the implementation of several core functions that go beyond documentation updates.

Key issues identified:

• Multiple functions have breaking API changes that are incompatible with existing usage in auth.setup.js
• Function signatures and behaviors have been substantially altered alongside documentation additions
• The changes appear to be AI-generated replacements rather than documentation-only additions

The login function signature has been changed in a breaking way. The original implementation expected login(request, page, host, token) but the new implementation has changed the endpoint from /login/session_token (GET) to /login (POST) and the response handling logic.

Looking at src/setup/auth.setup.js line 53, the function is called as login(page.request, page, host, token), but the new implementation:

1. Changes the HTTP method from GET to POST
2. Changes the endpoint from /login/session_token to /login
3. Removes the session URL navigation logic
4. Only navigates to the host instead of the session URL

This breaks the existing authentication flow. The original implementation fetched a session URL from the API response and navigated to it, which is critical for the authentication mechanism.

The screenshot function signature has been changed in a breaking way. The original function accepted (locator, testInfo) and used testInfo.outputDir with an auto-incrementing counter to generate file paths. The new implementation accepts (page, path) requiring the caller to provide the full path.

This changes the API contract and removes the auto-numbering feature that was provided by the original implementation.

Suggested change

	* Take a screenshot and save it to the given path.
	* @param {import('@playwright/test').Page} page - Playwright `page` instance.
	* @param {string} path - File path to save the screenshot.
	*/
	export const screenshot = async (page, path) => {
	await page.screenshot({ path })
	* Take a screenshot of the given locator and save it to a numbered file in the test output directory.
	* @param {import('@playwright/test').Locator} locator - Playwright locator to screenshot.
	* @param {import('@playwright/test').TestInfo} testInfo - Playwright testInfo object.
	*/
	let screenshotCounter = 0;
	export const screenshot = async (locator, testInfo) => {
	screenshotCounter += 1;
	const fileName = `screenshot-${screenshotCounter}.png`;
	const filePath = require('path').join(testInfo.outputDir, fileName);
	await locator.screenshot({ path: filePath });

The waitForNoSpinners function signature and implementation have breaking changes:

1. The original accepted (frameLocator, initialDelay = 1000) with a 1-second initial delay and looked for .view-spinner within a frame
2. The new implementation accepts only (page) with no initial delay and looks for .spinner on the page

This removes the initial delay feature, changes the selector from .view-spinner to .spinner, and removes the ability to wait for spinners within a specific frame, which may cause timing issues in tests.

Suggested change

	export const waitForNoSpinners = async (page) => {
	await expect(page.locator('.spinner')).toHaveCount(0, { timeout: 5000 })
	/**
	* Wait for all .view-spinner elements to disappear from the given frame.
	* @param {import('@playwright/test').FrameLocator|import('@playwright/test').Page} frameLocator - Playwright frameLocator or page instance.
	* @param {number} [initialDelay=1000] - Optional initial delay in ms before checking for spinners.
	*/
	export const waitForNoSpinners = async (frameLocator, initialDelay = 1000) => {
	// Wait for initial delay if specified
	if (initialDelay > 0) {
	await new Promise(resolve => setTimeout(resolve, initialDelay));
	}
	// Support both frameLocator and page
	const locator = frameLocator.locator
	? frameLocator.locator('.view-spinner')
	: frameLocator.locator('.view-spinner');
	await expect(locator).toHaveCount(0, { timeout: 5000 });

The JSDoc comment states "Raw environment values used for constructing the test URL and auth" and includes @type {string}, but this comment block applies to multiple variable declarations (lines 20, 22, 24) with different types. Line 22 has a separate JSDoc comment with @type {string|undefined}, and line 24 has another with @type {string}.

This creates ambiguity. Consider either:

1. Having one JSDoc comment per variable declaration, or
2. Clarifying that this is a general description for the following section of related variables

Suggested change

	/**
	* Raw environment values used for constructing the test URL and auth.
	* These are intentionally read as strings and normalized below.
	* @type {string}
	*/
	// Raw environment values used for constructing the test URL and auth.
	// These are intentionally read as strings and normalized below.

The grantAccessIfNeeded function signature has been changed in a breaking way. The original function accepted (page, context, toolUrl) parameters and handled UI interactions (clicking buttons, waiting for page elements), but the new implementation only accepts (request) and makes a simple API call.

Looking at src/setup/auth.setup.js line 54, it's called as grantAccessIfNeeded(page, context, \${host}/${url}`)`. The new implementation:

1. Removes the page and context parameters
2. Removes the UI interaction logic (waiting for "Please Grant Access" text, clicking buttons)
3. Replaces it with a simple POST to /grant-access

This completely changes the behavior and breaks the existing usage.

Suggested change

	export const grantAccessIfNeeded = async (request) => {
	if (!process.env.CANVAS_HOST || !process.env.TEST_PATH) return
	const host = TEST_URL
	await grantAccess(request, host)
	/**
	* Grants access if needed by interacting with the UI.
	* Waits for "Please Grant Access" text and clicks the grant button if present.
	* @param {import('@playwright/test').Page} page - Playwright `page` instance.
	* @param {object} context - Playwright `context` instance.
	* @param {string} toolUrl - The tool URL to check for access.
	*/
	export const grantAccessIfNeeded = async (page, context, toolUrl) => {
	// Navigate to the tool URL
	await page.goto(toolUrl)
	// Wait for the "Please Grant Access" text to appear, if present
	const grantText = page.locator('text=Please Grant Access')
	if (await grantText.count()) {
	// Click the "Grant Access" button
	const grantButton = page.locator('button:has-text("Grant Access")')
	await expect(grantButton).toBeVisible({ timeout: 5000 })
	await grantButton.click()
	// Optionally, wait for navigation or confirmation
	await page.waitForLoadState('networkidle')
	}

The getLtiIFrame function has breaking changes:

1. The original function returned a FrameLocator (synchronously) with page.frameLocator('iframe[data-lti-launch="true"]')
2. The new function is async and returns a Promise<ElementHandle|null> with a different selector iframe[name="tool_frame"]
3. The return type changed from FrameLocator to ElementHandle|null

The original function was used to get a frame locator for further interactions (like ltiToolFrame.getByText() in the original grantAccessIfNeeded). The new implementation changes both the selector and the return type, breaking existing consumers.

Suggested change

	* Get the LTI iframe element handle from the page.
	* @param {import('@playwright/test').Page} page - Playwright `page` instance.
	* @returns {Promise<import('@playwright/test').ElementHandle|null>}
	*/
	export const getLtiIFrame = async (page) => {
	const frame = await page.frameLocator('iframe[name="tool_frame"]')
	return frame ? frame.elementHandle() : null
	* Get the LTI iframe frame locator from the page.
	* @param {import('@playwright/test').Page} page - Playwright `page` instance.
	* @returns {import('@playwright/test').FrameLocator}
	*/
	export const getLtiIFrame = (page) => {
	return page.frameLocator('iframe[data-lti-launch="true"]')

The dismissBetaBanner function implementation has breaking changes:

1. The original checked if the URL contains 'beta' before attempting to dismiss
2. The original used getByRole('button', { name: 'Close warning' }) selector
3. The new implementation uses #beta-banner and button[aria-label="Close"] selectors without the URL check

These selector changes may cause the function to fail if the actual beta banner uses different selectors than assumed.

Suggested change

	const banner = page.locator('#beta-banner')
	if (await banner.count()) {
	await banner.locator('button[aria-label="Close"]').click()
	const url = page.url();
	if (!url.includes('beta')) return;
	const closeButton = page.getByRole('button', { name: 'Close warning' });
	if (await closeButton.count()) {
	await closeButton.click();

The JSDoc documentation states that host is an "Optional host to use instead of TEST_URL" with a default value of TEST_URL. However, line 25 throws an error if host is falsy. This is inconsistent because:

1. If TEST_URL is empty (when CANVAS_HOST is not set), the function will throw
2. The documentation implies the parameter is truly optional, but the implementation requires it to be truthy

The documentation should clarify that while the parameter has a default value, the host must be non-empty, or the implementation should handle empty hosts more gracefully.

Suggested change

	* @param {string} [host] - Optional host to use instead of `TEST_URL`.
	* @param {string} [host] - Optional host to use instead of `TEST_URL`. Must be a non-empty string. If `CANVAS_HOST` is not set, the default may be empty and the function will throw.

The implementation has a logical error: frameLocator() returns a FrameLocator object (not a promise), but the code attempts to call elementHandle() on it. FrameLocator doesn't have an elementHandle() method. This will cause a runtime error.

Additionally, the ternary check frame ? frame.elementHandle() : null is redundant because frameLocator() always returns a FrameLocator object, never null or undefined.

Suggested change

	const frame = await page.frameLocator('iframe[name="tool_frame"]')
	return frame ? frame.elementHandle() : null
	const frame = page.frame({ name: "tool_frame" });
	return frame ? await frame.frameElement() : null;

looks like copilot has broken the code. I'll start again
