A local two-step fictional workshop-registration form with labeled fields, preserved back navigation, error summary and a review-before-submit screen; no data is sent.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Create a step map and verify that Next, Review, and local completion have distinct behavior.
  • Produce an inspected label/group map with working for/id associations.
  • Record missing, malformed, endpoint, and repaired input behavior with actionable error messages.
  • Build a Back-navigation matrix proving that edits change the intended value and preserve other fields.
  • Produce a literal-text review that rejects an invalid complete request and reflects changed valid values.
  • Deliver source plus separate rule-test and rendered-journey evidence, with honest unverified checks.

Review and revise

Use these criteria to check your work and choose what to improve.

  • The implementation or declared simulation follows the supplied contract and retains inspectable original inputs.
  • Normal, boundary and rejected cases are recorded with expected versus observed results.
  • The changed case has a correct explanation and does not rely on hidden state.
  • The project includes source, outputs, instructions and honest tool, privacy and verification limits.

Before you begin

The idea in everyday life

The supplied Node suite checks six logic cases; the manual matrix covers label activation, missing values, Back, review, and local completion.

The idea

Pure validation tests check rules; browser tests check rendered labels, focus, navigation, and retained controls. Neither alone establishes a complete accessible form.

Test the complete form journey honestly — original worked practice

Pure validation tests check rules; browser tests check rendered labels, focus, navigation, and retained controls. Neither alone establishes a complete accessible form.

The supplied Node suite checks six logic cases; the manual matrix covers label activation, missing values, Back, review, and local completion.

  1. 1. Step 1

    Run node test-form.mjs and record the actual terminal output.

    You should see: 6 form logic checks passed.

    Pure validation tests check rules; browser tests check rendered labels, focus, navigation, and retained controls. Neither alone establishes a complete accessible form.

  2. 2. Step 2

    In the browser use Tab, Shift+Tab, Enter, and Space where appropriate to complete the fictional request. Record focus position after each step/error.

    You should see: A keyboard journey record based on actual observations.

    Pure validation tests check rules; browser tests check rendered labels, focus, navigation, and retained controls. Neither alone establishes a complete accessible form.

  3. 3. Step 3

    Repeat with 4 seats, decimal 2.5, empty nickname, and a Back edit; distinguish expected from observed for each.

    You should see: Four documented browser cases, with any failures preserved.

    Pure validation tests check rules; browser tests check rendered labels, focus, navigation, and retained controls. Neither alone establishes a complete accessible form.

  4. 4. Step 4

    Stop the local server with Ctrl+C; package the source, Node result, and browser matrix. Mark any unavailable screen-reader check unverified.

    You should see: A form project with rule tests, manual observations, and scoped verification limits.

    Pure validation tests check rules; browser tests check rendered labels, focus, navigation, and retained controls. Neither alone establishes a complete accessible form.

Now change one thing

Node passes but no browser was available. How many browser journeys may be reported as performed?

Your work

What to finish

Deliver source plus separate rule-test and rendered-journey evidence, with honest unverified checks.

Common mistake

Watch for this

Reporting Node assertions as a completed browser or screen-reader test.

How can I tell I understand it?

Demonstrate the rule: Pure validation tests check rules; browser tests check rendered labels, focus, navigation, and retained controls. Neither alone establishes a complete accessible form. Use the supplied variant to distinguish a changed result from a broken implementation.
