There are 3 ways to import `@playwright/test` library in the modern Node.js ecosystem:
- Using `require`: works great, this patch doesn't change it
- Using `import` statement from `.mjs` file - we have wrong `default` for @playwright/test that should be a `test`. This is what test checks for
- Using `import test from '@playwright/test'` from `.ts` file - was broken because TypeScript thought it's a CJS module, whereas it's a ESM module in reality.
Also, typescript types import from `.d.ts` file was broken because we had no default export (`export *` syntax does not export default).
This reverts commit a25b11659be8887b700311180fcd3653aa9e472b.
In a discussion with Dmitry Gozman we decided to revert this and instead
proceed with the following approach:
- rename `//browser_patches/firefox` to `//browser_patches/firefox-beta`
- rename `//browser_patches/firefox-stable` folder to
`//browser_patches/firefox`
In all of the folders, we will keep the `BUILD_NUMBER` original so that
it doesn't clash on the CDN.
This patch:
- starts downloading Firefox Stable equivalent by default
- starts running Firefox-Stable on our smoke tests (tests-1)
- starts running Firefox-Beta on our CQ1 tests (tests-2)
Note: there's a little confusion right now with browser names:
- `firefox-stable` - firefox-stable equivalent
- `firefox`- firefox-beta equivalent
I'll rename `firefox` to `firefox-beta` in a follow-up.
Fixes#6817
- Source now lives at `src/test`.
- Former folio tests live at `tests/playwright-test`.
- We use `src/test/internal.ts` that exposes base test without
Playwright fixtures for most tests (to avoid modifications for now).
- Test types live in `types/testFoo.d.ts`.
- Stable test runner is installed to `tests/config/test-runner` during `npm install`.
- All deps including test-only are now listed in `package.json`.
Non-test deps must also be listed in `build_package.js` to get included.
This makes it much nicer to use `BrowserType` because it no longer has a template.
Technically a breaking change because of the rare edge case where someone used their own non-browser type inside the template, but I don't consider that intended behavior and think this is fine.
Browser registry is responsible for 3 things:
1. Remove downloaded browsers if there are no packages that refer to them
2. Install default browsers needed for the current package
3. Install browsers on-demand when used through Playwright CLI
Currently, registry relies on a single "download" field in `browsers.json`
to carry both (1) and (2). However, browsers in (3) are marked as
`download: false` so that they aren't installed automatically in (2), so
auto-remove procedure in (1) removes them on subsequent installation.
One possible approach to fix this would be modifying package's `browsers.json` to
change `download: false` to `true` when browsers are installed with
Playwright CLI. This approach was explored here:
bc04a51800
We decided against this since we have a history of issues related to
package modifications after NPM installation. This breaks all
sorts of yarn/npm caching mechanisms.
Instead, this patch is a two-step refactor:
- remove the "download" field in `browsers.json`. Now, all registries
(including old ones from previously-released versions) will retain any
browsers that are mentioned in the `browsers.json`.
- add a new flag "installByDefault", that is **only used** for default
installation.
With this change, the registry tasks are done like this:
- (1) auto-removal: if browser has a back reference, it is retained,
otherwise it is removed from registry
- (2) default installation: use only `installByDefault` to carry default installations
- (3) CLI installation: simply installs browsers. Since we retain
everythings that's referenced in (1), browsers aren't removed.
Fixes#5902
We get relative registry path when PLAYWRIGHT_BROWSERS_PATH or HOME is relative.
In this case, it would be good to resolve to the same absolute path
during installation and execution, and we can usually do that using INIT_CWD.
- Introduce internal "out of process" start()/stop() mode.
- This mode is used both in regular tests and installation tests.
- Emulate basic driver installation, browser download and running.
This patch starts downloading FFMPEG like we download our browsers
instead of bundling it in the NPM package.
With this patch, NPM size is reduced from 8.8MB to 1.7MB.
Consequences:
- `npx playwright` is drastically faster now
- playwright driver for language bindings is way smaller
- projects that bundle Playwright can pass Apple Notorization
Fixes#5193
- Allow specifying which browsers to install. This comes handy in playwright-cli.
- Print "npx playwright" as a tool name in help messages, instead of "cli".
