Root index.js is only used for local development, so
assuming dev mode there is fine. This way we do not have
to worry about calling setUnderTest early enough.
This patch removes the `PLAYWRIGHT_GLOBAL_INSTALL=1` variable
and instead introduces a new var - `PLAYWRIGHT_BROWSERS_PATH`.
You can specify `PLAYWRIGHT_BROWSERS_PATH` to affect where playwright
installs browsers and where it looks for browsers.
Fixes#1102
This patch:
- removes `browserType.downloadBrowserIfNeeded()` method. The method
turned out to be ill-behaving and cannot not be used as we'd like to (see #1085)
- adds a `browserType.setExecutablePath` method to set a browser
exectuable.
With this patch, we take the following approach towards managing browser downloads:
- `playwright-core` doesn't download any browsers. In `playwright-core`, `playwright.chromium.executablePath()` returns `null` (same for firefox and webkit).
- clients of `playwright-core` (e.g. `playwright` and others) download browsers one way or another.
They can then configure `playwright` with executable paths and re-export the `playwright` object to their clients.
- `playwright`, `playwright-firefox`, `playwright-chromium` and `playwright-webkit` download
browsers. Once browsers are downloaded, their executable paths are saved to a `.downloaded-browsers.json` file. This file is read in `playwright/index.js` to configure browser executable paths and re-export the API.
- special case is `install-from-github.js` that also cleans up old browsers.
This patch starts respecting `PLAYWRIGHT_DOWNLOAD_HOST` env variable
in `playwright` package and it's vendored flavors (`playwright-firefox`,
`playwright-chromium` and `playwright-webkit`).
Fixes#1045
This patch makes it so all our packages, like `playwright` and
browser-specific flavors, download browsers to their
directories rather then using directory of `playwright-core`.
This way yarn@1 caches are not busted: they didn't expect that directory
content might change after packages's explicit install step
is failed, there's that was what we were doing.
Fixes#1085
