![]() ![]() This gives a lot of lead time to react on the potential browser update issues. Playwright's WebKit version matches the recent WebKit trunk build, before it is used in Apple Safari and other WebKit-based browsers. Instead you can test against the recent Firefox Stable build. Playwright doesn't work with the branded version of Firefox since it relies on patches. Playwright's Firefox version matches the recent Firefox Stable build. ![]() So if you are part of the organization that uses such policies, it is easiest to use bundled Chromium for your local testing, you can still opt into stable channels on the bots that are typically free of such restrictions. Google Chrome and Microsoft Edge respect enterprise policies, which include limitations to the capabilities, network proxy, mandatory extensions that stand in the way of testing. If your site relies on this kind of codecs (which is rarely the case), you will also want to use the official channel. Chromium does not have all the codecs that Google Chrome or Microsoft Edge are bundling due to various licensing considerations and agreements. Media codecs Īnother reason for testing using official binaries is to test functionality related to media codecs. In this case, you can opt into one of the stable channels, "chrome" or "msedge". Having said that, testing policies often require regression testing to be performed against the current publicly available browsers. You catch breakage early and have a lot of time to fix it before the official Chrome update. Since Playwright is ahead of Stable channels for the browsers, it gives peace of mind that the upcoming Google Chrome or Microsoft Edge releases won't break your site. Using the default Playwright configuration with the latest Chromium is a good idea most of the time. When to use Google Chrome & Microsoft Edge and when not to? Defaults Run with the -help option to see a full a list of browsers that can be installed. Google Chrome or Microsoft Edge installations will be installed at the default global location of your operating system overriding your current browser installation. In particular, the current Playwright version will support Stable and Beta channels of these browsers.Īvailable channels are chrome, msedge, chrome-beta, msedge-beta or msedge-dev. ![]() While Playwright can download and use the recent Chromium build, it can operate against the branded Google Chrome and Microsoft Edge browsers available on the machine (note that Playwright doesn't install them by default). Since the Chromium project is ahead of the branded browsers, when the world is on Google Chrome N, Playwright already supports Chromium N+1 that will be released in Google Chrome and Microsoft Edge a few weeks later. Chromium įor Google Chrome, Microsoft Edge and other Chromium-based browsers, by default, Playwright uses open source Chromium builds. To run on other/multiple browsers click the play button's dropdown from the testing sidebar and choose another profile or modify the default profile by clicking Select Default Profile and select the browsers you wish to run your tests on.Ĭhoose a specific profile, various profiles or all profiles to run tests on. Safari will let you go through with the download if you ignore all the warnings.The VS Code test runner runs your tests on the default browser of Chrome. ![]() Security: While other browsers will warn you if you land on a suspicious website, Firefox will actually block downloads it deems malicious.Firefox allows you to make some of these tweaks. You can't re-arrange toolbars, or make other adjustments to your tastes. Customizability: One feature Safari lacks, due to some design decisions by Apple, is the ability to customize the interface.But if there's a website that just won't work right for you in Safari, the Quantum rendering engine from Mozilla may iron things out for you. Compatibility: In terms of compatibility, both Firefox and Safari (and Chrome, for that matter) are pretty compliant with web standards.Privacy: Firefox's private browsing feature goes beyond just not recording your history, and will actually prevent websites from tracking you.If freedom and privacy are important to you, Firefox's development process is more transparent, and there isn't a for-profit company making decisions about it. Freedom: The Mozilla Corporation operates as a not-for-profit, and Firefox itself is open source software.It also has a larger portion of the market (second only to Chrome), so developers are more likely to consider Firefox for their extensions than Safari. One example is extensions: the Firefox extension library has been around for longer, and likely has a wider selection of add-ons. While both are mature products, Firefox may have an upper hand in some areas. Maturity: Firefox has been around longer than Safari. ![]()
