Happy start of 2019! This is another post from Appium contributor Jonah Stiennon. In the past, I & # x27; ve labeled his contributions to Appium Pro & quot; guest posts & quot;, but as of now, Jonah has officially joinCloud Greyas a partner! More to come about Jonah later, but meanwhile get ready to see more of him in this newssheet, on Appium & # x27; s GitHub, and around the world consulting with you all.

Thanks to Appium contributor@ AnnaWyrwal, there are two new desired capabilities uncommitted in the modish Appium beta release (see our on how to install beta adaptation of Appium). Under the correct circumstances these can improve the time it occupy to start an Android session.

skipDeviceInitialization

Available for all Android platform, theskipDeviceInitializationdesired capability can be pass with the boolean valuetrueto hop-skip installing theio.appium.settings appon the gimmick. This peculiar app is installed by theAppium Android Driverat the beginning of each test and is used to manage specific settings on the gimmick, such as:

• wifi/data settings
• disabling animation
• setting a locale
• IME settings

Without the io.appium.settings app, the Appium Android driver can not automatize these functions, but if the device antecedently had this app installed by Appium, it doesn & # x27; t need to install it again. If you know that your twist is already in the proper province then you can setskipDeviceInitialization to trueand skip the time it takes to reinstall it.

For autonomous testing across multiple user personas, check out SUSATest — it explores your app like 10 different real users.

Appium already insure if the settings app is already installed on the device, but with this capability enabled it even skips the chit to see if the app is installed.

This is most useful for tests which postdate a previous successful test, or tryout being run on the same emulators or device over and over.

skipServerInstallation

The skipServerInstallationdesired capability only applies when using theUiAutomator2automation method. The way the UIAutomator2 driver act, it installs a specialserveronto the device, which hear to test dictation from Appium and executes them.

By default, Appium installs this server onto the device at the beginning of every examination session. If the value ofskipServerInstallation is set to true, you can cut the time it direct to install this server.

Of course, without the waiter on the device Appium can & # x27; t automate it, but if you know that the server was instal during a previous test run you can safely hop-skip this stride.

A warning: make sure to disable this capacity if you have updated the version of Appium you are using, because you want it to install the late variation of the UIAutomator2 host.

This capableness is also most useful for trial which follow a previous successful examination, or examination being run on the same emulators or devices over and over.

Using appPackage and appActivity to launch existing apps

Another major time-saver when it arrive to Android tests is utilize theappPackageand appActivityhope capability instead of theapp capability.

We postulate to tell Appium whichappto test. Usually we use the app capability, which can be a path to a.apk, .apks, or .zipfile stored on your computer & # x27; s filesystem or stored on a public website. If the app under test is known to already be establish on the device (most belike from a previous test run), the app parcel name and independent activity can be legislate alternatively (usingappPackageand appActivitycraved capabilities). Skipping the clip to download a tumid file or install it on the Android operating system take to big economy.

As with the previously discussed capabilities, make sure that youdoinstall the app again if you are testing a newer version. Nothing is more frustrating than accidentally running test on an older version of your app!

Honorary Mention: ignoreUnimportantViews

The ignoreUnimportantViewsdesired capability is not new, and is outside the scope of this post, but it deserves to be mentioned as another way to potentially speed up Android automation tests, especially if your exam focus on find many elements using XPath locators. Set this totrue to speed up Appium & # x27; s ability to chance element in Android apps. (To learn more about this capability and other capabilities utilise for speeding up test execution, check out).

Below is an example of theskipDeviceInitialization, skipServerInstallation, and appPackagecraved capabilities be used to speed up an Android test. The first tryout runs without these capabilities in order to make sure that the io.appium.settings app and the UiAutomator2-server are installed. The second exam lam without devil to check or establish these dependencies or the app under trial on the device. By my not-so-rigorous analysis,skipDeviceInitializationand skipServerInstallationsaved about 1 2d per tryout and usingappPackagesaved ten seconds per test (generally because the representative code downloads an app from the internet).
