This is Appium driver for automating Firefox on different platforms, including Android.
The driver only supports Firefox and Gecko-based web views (Android only) automation using W3C WebDriver protocol.
Under the hood this driver is a wrapper/proxy over geckodriver binary. Check the driver release notes and the official documentation to get more details on the supported features and possible pitfalls.
Note
Since version 1.0.0 Gecko driver has dropped the support of Appium 1, and is only compatible to Appium 2. Use the
appium driver install geckocommand to add it to your Appium 2 dist.
It is mandatory to have both Firefox browser installed and the geckodriver binary downloaded on the platform where automated tests are going to be executed. Firefox could be downloaded from the official download site and the driver binary could be retrieved from the GitHub releases page. The binary must be put into one of the folders included to PATH environment variable. On macOS it also might be necessary to run xattr -cr "<binary_path>" to avoid notarization issues.
Then you need to decide where the automated test is going to be executed. Gecko driver supports the following target platforms:
- macOS
- Windows
- Linux
- Android (note that
androidcannot be passed as a value toplatformNamecapability; it should always equal to the host platform name)
In order to run your automated tests on an Android device it is necessary to have Android SDK installed, so the destination device is marked as online in the adb devices -l command output.
Since driver version 1.3.0 you can automate the validation for the most of the above
requirements as well as various optional ones needed by driver extensions by running the
appium driver doctor gecko server command.
Gecko driver allows defining of multiple criterions for platform selection and also to fine-tune your automation session properties. This could be done via the following session capabilities:
| Capability Name | Description |
|---|---|
| platformName | Gecko Driver supports the following platforms: mac, linux, windows. The fact your test must be executed on Android is detected based on moz:firefoxOptions entry values. Values of platformName are compared case-insensitively. |
| browserName | Any value passed to this capability will be changed to 'firefox'. |
| browserVersion | Provide the version number of the browser to automate if there are multiple versions installed on the same machine where the driver is running. |
| appium:automationName | Must always be set to Gecko. |
| appium:noReset | Being set to true adds the --connect-existing argument to the server, that allows to connect to an existing browser instance instead of starting a new browser instance on session startup. |
| appium:marionettePort | Selects the port for Geckodriver’s connection to the Marionette remote protocol. The existing Firefox instance must have Marionette enabled. To enable the remote protocol in Firefox, you can pass the -marionette flag. Unless the marionette.port preference has been user-set, Marionette will listen on port 2828, which is the default value for this capability. |
| appium:systemPort | The number of the port for the driver to listen on. Must be unique for each session. If not provided then Appium will try to detect it automatically. |
| appium:verbosity | The verbosity level of driver logging. By default minimum verbosity is applied. Possible values are debug or trace. |
