Edit this Doc Getting Started
This doc will get you up and running with a simple Appium test and introduce you to some basic Appium ideas. For a fuller introduction to Appium concepts, please check out the conceptual introduction.
Installation via NPM
If you want to run Appium via an
npm install, hack with Appium, or contribute
to Appium, you will need Node.js and NPM (use
brew install node to install
Node.js. Make sure you have not installed Node or Appium with
you'll run into problems). We recommend the latest stable version, though
Appium supports Node 8+.
The actual installation is as simple as:
npm install -g appium
Installation via Desktop App Download
Simply download the latest version of Appium Desktop from the releases page.
You probably want to use Appium to automate something specific, like an iOS or Android application. Support for the automation of a particular platform is provided by an Appium "driver". There are a number of such drivers that give you access to different kinds of automation technologies, and each come with their own particular setup requirements. Most of these requirements are the same requirements as for app development on a specific platform. For example, to automate Android applications using one of our Android drivers, you'll need the Android SDK configured on your system.
At some point, make sure you review the driver documentation for the platform you want to automate, so your system is set up correctly:
- The XCUITest Driver (for iOS apps)
- The UiAutomator2 Driver (for Android apps)
- The Windows Driver (for Windows Desktop apps)
- The Mac Driver (for Mac Desktop apps)
- (BETA) The Espresso Driver (for Android apps)
Verifying the Installation
To verify that all of Appium's dependencies are met you can use
appium-doctor. Install it with
npm install -g appium-doctor, then run the
appium-doctor command, supplying the
--android flags to verify
that all of the dependencies are set up correctly.
When all is said and done, Appium is just an HTTP server. It sits and waits for connections from a client, which then instructs Appium what kind of session to start and what kind of automation behaviors to enact once a session is started. This means that you never use Appium just by itself. You always have to use it with a client library of some kind (or, if you're adventurous, cURL!).
Luckily, Appium speaks the same protocol as Selenium, called the WebDriver Protocol. You can do a lot of things with Appium just by using one of the standard Selenium clients. You may even have one of these on your system already. It's enough to get started, especially if you're using Appium for the purpose of testing web browsers on mobile platforms.
Appium can do things that Selenium can't, though, just like mobile devices can do things that web browsers can't. For that reason, we have a set of Appium clients in a variety of programming languages, that extend the regular old Selenium clients with additional functionality. You can see the list of clients and links to download instructions at the Appium clients list.
Before moving forward, make sure you have a client downloaded in your favorite language and ready to go.
Now we can kick up an Appium server, either by running it from the command line like so (assuming the NPM install was successful):
Or by clicking the huge Start Server button inside of Appium Desktop.
Appium will now show you a little welcome message showing the version of Appium
you're running and what port it's listening on (the default is
port information is vital since you will have to direct your test client to
make sure to connect to Appium on this port. If you want to change, the port,
you can do so by using the
-p flag when starting Appium (be sure to check out
the full list of server
Running Your First Test
- We'll assume you have an Android 8.0 emulator configured and running (the example will work on lower versions, just fix the version numbers accordingly)
- We'll assume you have this test APK downloaded and available on your local filesystem
Setting up the Appium Client
For this example, we'll use Webdriver.io as our Appium client. Create a directory for this example, then run:
npm install webdriverio
Now we can create our test file (name it whatever you like) and initialize the client object:
The next thing we need to do is to start an Appium session. We do this by
defining a set of server options and Desired Capabilities, and calling
wdio.remote() with them. Desired Capabilities are just a set of keys and
values that get sent to the Appium server during session initialization, that
tell Appium what kind of thing we want to automate. The minimum set of required
capabilities for any Appium driver should include:
platformName: the name of the platform to automate
platformVersion: the version of the platform to automate
deviceName: the kind of device to automate
app: the path to the app you want to automate (but use the
browserNamecapability instead in the case of automating a web browser)
automationName: the name of the driver you wish to use
For more information on Desired Capabilities and for a list of all the Capabilities you can use in Appium, see our Capabilities doc.
So here is how we begin to construct a session in our test file:
Running Test Commands
You can see that we've specified our Appium port and also constructed our Desired Capabilities to match our requirements (but don't forget to replace the path with the actual download path for your system). We've registered this fact with webdriverio and now have a client object which will represent the connection to the Appium server. From here, we can go ahead and start the session, perform some test commands, and end the session. In our case, we will simply tap into a few menus and then back out the way we came before ending the session:
What's going on here is that after creating a session and launching our app,
we're instructing Appium to find an element in the app hierarchy and click on
it. Specifically, webdriverio has a convention where the
~ prefix means to
find an element by its "accessbility id", which in the case of Android means an
element's "content description". So we find and tap on these elements in order
to navigate through the app's menu system. Then we can use the
to trigger the Android "back" behavior and get back to where we started before
ending the session.
Putting it all together, the file should look like:
You can try and run this test on your own. Simply save it and execute it using
node. If everything is set up correctly, you'll see Appium begin spitting out
lots of logs and eventually the app will pop up on the screen and start
behaving as if an invisible user were tapping on it!
