Link Integrity & Navigation

Run 23 test cases across 3 parallel agents covering internal links, external links, and link behavior/semantics.

Setup

URL="${ARGUMENTS:-http://localhost:3000}"
TIMESTAMP=$(date +%Y%m%d-%H%M%S)
OUTDIR="test-results/test-links/$TIMESTAMP"
mkdir -p "$OUTDIR/screenshots" "$OUTDIR/snapshots" "$OUTDIR/traces"

Pre-check: Discover Links

playwright-cli -s=links-discovery open "$URL"
playwright-cli -s=links-discovery run-code "async page => {
  const links = await page.locator('a[href]').all();
  const hrefs = await Promise.all(links.map(l => l.getAttribute('href')));
  const origin = new URL(page.url()).origin;
  const internal = hrefs.filter(h => h && (h.startsWith('/') || h.startsWith(origin)));
  const external = hrefs.filter(h => h && h.startsWith('http') && !h.startsWith(origin));
  return { total: hrefs.length, internal: internal.length, external: external.length };
}"

Parallel Execution — 3 Subagents

Agent 1: Internal Links (-s=links-internal)

Tests all internal link targets.

playwright-cli -s=links-internal open "$URL"
playwright-cli -s=links-internal tracing-start

Test Cases:

TC	Test	How to Check
TC-L1	All internal links resolve (no 404s)	run-code to collect all internal hrefs, fetch each with HEAD request, check for 200/301/302
TC-L2	Internal links use correct paths	run-code to verify links are well-formed (no double slashes, no broken relative paths)
TC-L3	Navigation menu links work	Find nav element, click each link, verify page loads (no error)
TC-L4	Footer links work	Find footer element, check all links resolve
TC-L5	Sidebar links work	If sidebar exists: check all links resolve
TC-L6	In-content links work	Find links within main content area, verify they resolve
TC-L7	CTA buttons link to correct targets	Find primary CTA elements (buttons with href or onclick navigation), verify targets exist
TC-L8	Logo links to homepage	Find logo/brand link, verify it links to / or homepage URL

Agent 2: External Links (-s=links-external)

Tests external link behavior and security.

playwright-cli -s=links-external open "$URL"
playwright-cli -s=links-external tracing-start

Test Cases:

TC	Test	How to Check
TC-L9	External links open in new tab	run-code to find external links, verify target="_blank" attribute
TC-L10	External links have rel="noopener noreferrer"	run-code to find external links with target="_blank", verify rel includes noopener and noreferrer
TC-L11	External links not broken (HEAD check)	run-code to fetch external URLs with HEAD request, check for non-error status codes
TC-L12	Social media links correct	run-code to find links to known social platforms (twitter, facebook, linkedin, etc.), verify they point to valid profiles
TC-L13	No links to HTTP (should be HTTPS)	run-code to find any links starting with http:// (not https://), flag as insecure

Agent 3: Link Behavior (-s=links-behavior)

Tests link semantics, visual states, and special link types.

playwright-cli -s=links-behavior open "$URL"
playwright-cli -s=links-behavior tracing-start

Test Cases:

TC	Test	How to Check
TC-L14	Links have descriptive text	run-code to find links with generic text: "click here", "here", "read more", "link", "more"
TC-L15	Links visually distinguishable from text	run-code to compare link styles (color, underline) vs paragraph text — must be distinct
TC-L16	Visited links have different style	run-code to check if :visited styles are defined (different color from unvisited)
TC-L17	Links have hover state	hover over links, run-code to check style changes on hover
TC-L18	Links have focus state	Tab to links, run-code to check focus outline/indicator is visible
TC-L19	Anchor links scroll to correct section	Find anchor links (href="#...") , click them, verify scroll position targets correct element
TC-L20	Download links have download attribute	run-code to find links to downloadable file types (.pdf, .zip, .doc), check for download attribute
TC-L21	Email links use mailto:	run-code to find links containing email addresses, verify they use mailto: protocol
TC-L22	Phone links use tel:	run-code to find links containing phone numbers, verify they use tel: protocol
TC-L23	No orphan pages	Navigate all internal links discovered, build a page graph, check all pages are reachable from main nav

Report Generation

After all 3 agents complete, merge results into $OUTDIR/report.md.

Include a link inventory:

• Total links found: N
• Internal: N (N broken)
• External: N (N broken)
• Special: N mailto, N tel, N download

Group results by category:

1. Internal Links (TC-L1 through TC-L8)
2. External Links (TC-L9 through TC-L13)
3. Link Behavior (TC-L14 through TC-L23)
