Tests
What each test checks, against real files in a real browser, and the negative control that proves each check can fail.
No mocks: the tests load the real release files, from the published path, into a real browser. tests/harness.mjs launches Playwright's Chromium (or BROWSER=firefox|webkit) and routes https://api.storyboards.sgit.ai/ to this checkout, so a test that loads /v0/v0.1/v0.1.0/storyboard.js gets the bytes in the tree, with the headers GitHub Pages sends. SB_UNDER_TEST=src routes every release path to src/, to test the next release before it is cut.
| Test | Checks | Its negative control |
|---|---|---|
test_formats.mjs (Node) | a gen-z and a pki storyboard validate clean; the markdown has a heading per panel and is the same bytes twice; the graph's ids are unique, every edge names real nodes, there is a has_panel per panel and a next between each | a storyboard with an unknown character, an unknown mood and an unknown kind fails, naming each; the pki storyboard without the security pack fails on its props |
test_render.mjs (Chromium) | <sg-storyboard> on another origin draws every panel of both fixtures with no console error; the grid and script views; view="panel" with the security pack's vault; scripts load with the manifest's SRI strings; the kit's vocabulary equals formats.js's, list by list; the SVG, animated SVG, embedded-font SVG, sheet, PNG and JPEG exports, their sizes, and the same panel exporting to the same bytes | a script given another file's integrity string does not run |
test_site.mjs (Chromium) | every page of the website, assembled as Pages serves it, opens with no error; the home page's live embed draws |
The fixtures in tests/fixtures/ are real storyboards from the two origin sites (gen-z's Everything is connected, with graphs and a map, and pki's The first key, with the security props), with their casts.
