Guide to Playwright visual regression tests in Handsontable: when a screenshot is justified, the tablePage fixture, naming, reg-suit comparison and demo routes.

  • Writing a Playwright visual regression test for a Handsontable feature
  • SKILL.md covers Decision rule, Custom fixture: tablePage, Test naming and Screenshot workflow, plus 6 more sections
  • Calls npm
  • Adding a demo route so a new feature can be captured

What it does

Visual tests live in the visual-tests folder as Playwright and TypeScript specs, and reg-suit compares their screenshots with golden records. Two jobs are covered: adding a visual test for an existing demo route, and adding a new feature demo route to the js demo under examples/next/visual-tests before writing its test. The documentation examples tree is not served by the visual suite.

A decision rule limits captures. A screenshot proves pixels only, so each distinct visual state gets one capture, asserted first, while focus, selection, data and menu facts stay as Playwright assertions in the E2E tests, and a visual spec is added to those assertions, never instead of them. Specs import the custom visualTest runner, since a bare test call is a lint error. The tablePage fixture opens the demo page, waits for the table, disables CSS animations and clears stray text selections before each capture, and file names are kebab-case descriptions of the visual state.

When your agent uses it

  • Writing a Playwright visual regression test for a Handsontable feature
  • Adding a demo route so a new feature can be captured
  • Deciding whether a behavior deserves a screenshot at all

Example prompts

  • “Add a visual test for the nested header class name feature using the tablePage fixture.”
  • “Create a demo route for the new row hiding feature and a visual spec for it.”
  • “Does selecting a cell need a screenshot, or is an assertion enough?”

Requirements

  • A checkout of the Handsontable repository
  • Playwright

What it can do on your machine

Read from SKILL.md and the folder at commit 68b5e97. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Handsontable Visual Testing loads about 2.3k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 1,031 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,031 words (~2,325 tokens).

“Visual tests live in visual-tests/ (Playwright + TypeScript); reg-suit compares screenshots against golden records. Two workflows: (a) add a visual test for an existing demo route, (b) add a new /-demo route to the js demo in examples/next/visual-tests/js/demo/ (the creating-visual-test-examples…”
