![]() ![]() Instead, you tell Appium which drivers you care to use. That's because no drivers are included by default with Appium 2.x. What this is telling us is that you need to have Appium install a driver before you run any tests. (And you'll get the same message with respect to plugins). Use the "appium driver" command to install the one(s) you want to use. Instead, Appium 2.0 beta versions will be available with a special NPM tag next, so you can install it on any platform using NPM as follows: npm install -g it! Installing Appium driversĪt this point, after installing Appium 2.x for the first time, if you run the server, you'll get a line in the logs that looks something like this: ![]() We're going to take the opportunity to make those changes now, and keep bringing Appium into the future.Īt the moment, Appium 2.0 is not the main line of Appium development, so it cannot be installed with a simple npm install -g appium. There has been a lot of deferred work on Appium that kept getting pushed off because it could introduce a breaking change into the API. And it would be even better for anyone in the world to be able to easily create Appium plugins that can implement new commands, or alter the behavior of existing commands! Using the same model as our driver ecosystem, anyone can create plugins like these and easily share them with the world of Appium users. It would be better to be able to install these features as independent plugins. Not every automation use case requires these features, but the code and dependencies that support these features are included with every Appium install. Some good examples of this would be the Find Element by Image API or the Appium + Test AI Classifier. In addition to drivers, it's become clear that there are a huge variety of use cases for Appium, which involve the use of special commands or special ways of altering the behavior of Appium for specific commands. All of these custom drivers can then be installed by any Appium user (or custom drivers could be private, or sold, or whatever you can dream of). Once the drivers are decoupled from Appium, it's quite an obvious question to ask: what's special about these drivers, anyway? Why couldn't anyone else create a driver for their own platform? Well with Appium 2.0, they can, and they should! By using any existing Appium drivers as a template, anyone can create their own custom drivers with a minimum of extra code. It also makes it possible to freely update drivers independently of Appium and of one another, so that you can get the latest changes for one driver while sticking with a known stable version of another driver, for example. This decreases the size of an Appium install dramatically, and makes it so that you don't need to install drivers that you don't need to use. With Appium 2.0, the code for these drivers will no longer be bundled with the main Appium server. ![]() They really ought to be developed as independent projects that implement the same interface and can be used equivalently with the Appium server. Decouple the drivers! Appium's platform drivers (the XCUITest driver, UiAutomator2 driver, Espresso driver, etc.) have very little in common with one another.If you've been around the Appium world for a while, you've probably heard that Appium 2.0 has been "coming soon" for a very long time! I'm happy to report that work on it has been progressing well, and Appium 2.0 is now ready to use as a beta! Appium 2.0's visionīefore we get into the details of installing and running Appium 2.0, it's worth mentioning some of the core goals for this next major revision of Appium: ![]()
