Unit tests for endpoints and renderer

Ramil Karimov,developer

February 9

Tests for server-side logic: sitemap generation helpers, RSS feed sanitizer, and the page renderer. Most of these functions are currently not exported and need to be made testable first.

Part of Add tests and CI integration (sub-task 3 of 4). Requires testing environment setup first. Can be done in parallel with utility tests.

Prerequisite: export helper functions

Before writing tests, these currently-private functions need to be exported (or extracted into separate testable modules):

sitemap-appendix.xml/+server.js:getRouteFromPath , calculatePriority,extractSections
feed.xml/+server.js: sanitizeContentForRSS
page-renderer.svelte.js: getCoverUrl, createSvelteKitStateMocks, createRenderContext

Sitemap helpers

From src/routes/sitemap-appendix.xml/+server.js:

`getRouteFromPath(filePath)`

Strips +page.svelte and .. prefix
Prepends base path

`calculatePriority(path)`

/ (root) returns "0.9"
Each nesting level reduces by 0.1
Minimum priority is "0.1" (deeply nested paths don't go below)
Returns string with one decimal place

`extractSections(pagePaths)`

Extracts parent sections from page paths
Returns sorted, deduplicated array
Each section has trailing slash
Handles deeply nested paths (creates all intermediate sections)

Feed sanitizer

From src/routes/feed.xml/+server.js:

`sanitizeContentForRSS(html)`

Removes onload, onerror and other event handler attributes
Removes single-quoted event handlers
Removes style attributes (both quote types)
Removes javascript: URLs
Removes data-* attributes
Removes class attributes
Removes id attributes
Preserves actual content text and tag structure
Test with HTML containing all pattern types combined

Page renderer

From src/lib/page-renderer.svelte.js:

`getCoverUrl(cover)`

Returns empty string for null/undefined/falsy
Returns the string directly if cover is a string
Extracts img.src from object form
Returns empty string if object has no img.src

`createSvelteKitStateMocks(filePath, pageData)`

Returns object with url, params, route, data, form, error, status
url is a valid URL object based on filePath
data.info merges defaults with provided pageData
Default date is '01-01-2024'

`createRenderContext`

Returns a Map
Has 'meta' key with a Store instance
Has '__request__' key with page mock

Date formatting in `renderBlogPage`

DD-MM-YYYY converts to YYYY-MM-DDT00:00:00-00:00
Fallback to 01-01-2024 when no date provided

`EXCLUDE_PATHS` filtering

Pages matching excluded paths return null
Pages not in the set are rendered normally
