instructions in the Playwright contributing guide. Keep the documented
`checkForViewportScreenshot` example and its viewport text-hiding behavior; do
not add a grid helper.

What is this paragraph trying to say? Don't add a -- between the run command and the flags. Or something else? Either way it might need to be reworded.

Maybe best to say "see DicomTagBrowserPageObject for an example of this?

Does checkForGridScreenshot exist yet?

I might be wrong, but the inverse that is stated is not the inverse of the previous sentence. I think maybe the sentence you might be looking for is "A helper that is not specific to a certain segmentation representation should not carry the representation in its name".
But then again I might be missing something.

I added some clarifications here.

Thanks for this. See my minor comments.
- Reword the note on passing Playwright flags through pnpm scripts - Point to DicomTagBrowserPageObject as an example of a dialog page object - Correct the naming rule for representation-agnostic helpers - Drop the checkForGridScreenshot reference until the helper lands

testing documentation to set TEST_ENV=true before invoking Playwright, so direct
runs use the same test environment as E2E scripts. Leave the existing guidance

Maybe just the one suggestion from Coderabbit is left.

- Around line 330-334: Update the screenshot guidance in the Playwright testing
section to allow `checkForScreenshot` with `viewportPageObject.grid` for
whole-grid captures in MPR and 3D layouts, while retaining its use for
non-viewport locators. Clarify that `checkForViewportScreenshot` is for
capturing a single viewport.

Context
The Playwright E2E contribution guide currently lives in
tests/CONTRIBUTING.md, next to the suite, and the Playwright testing docs page links out to it on GitHub. Contributors reading docs.ohif.org have to leave the site to find the conventions, and the guide is invisible to the docs sidebar and search.This PR moves the guide into the docs site so there is a single, discoverable source.
Changes & Results
platform/docs/docs/development/playwright-contributing.mdwith the full guide (fixtures, page objects, normalized viewport coordinates, render waits, assertions, screenshot baseline rules, naming, PR submission). It appears in the Development section of the sidebar as "Contributing E2E Tests", directly after "Playwright Testing".checkForViewportScreenshotandcheckForGridScreenshot, and to limit the genericcheckForScreenshotto non-viewport locators such as panels and dialogs. This matches the helper set introduced in test(e2e): capture viewport and grid screenshots text-free across the suite #6296.tests/CONTRIBUTING.mdso the guide is not maintained in two places.Depends on #6296 for the
checkForGridScreenshothelper the guide references. That PR also editstests/CONTRIBUTING.md, so whichever lands second will see a modify/delete conflict on that file; keeping the deletion is the correct resolution.Testing
