Download Java Client Jar For Appium
Phebe Aherns
Can any one please tell me how do I make sure which appium java-client jar version is compatible with which selenium jar version. I have tried a lot of different appium java-client versions and also selenium versions and I faced below issues :-
The Appium Java client has dedicated classes to support most of the official Appium drivers. For other driversyou could simply use the AppiumDriver classor build your custom derivatives from it. Check the Drivers Supportarticle to learn more about the current driver class implementations.

For Appium-Java client 8.0.2 is it necessary to use appium node 2.0 Beta ?
As I am not able to do few of the feature on 1.X.X appium server for example programmatically running the server , taking out adb logs etc. Can anybody tell ?
java client 8 and above are compatible with appium 2 features so it is reasonable to upgrade your appium server as well. but, I think you should be able to do the same thing (or at least most of them) with those versions as well.
The TouchActions and MultiTouchActions classes for automating gestures from your client code have been deprecated. Support for these actions will be removed from future Appium versions. It is recommended to use W3C Actions instead or the corresponding extension methods for the driver (if available).
Now Java client supports Selenium 4, which means it is strictly W3C compliant. Previously, JSON wire protocol acts as a mediator between client libraries and WebDrivers. It transfers data between the client and the server on the web. The server doesn't understand the programming language in which the program is created, it just understands the protocol. Old JWP -based servers are not supported anymore, and it won't be possible to use the new client version with them.
I will briefly explain how to install Appium v2. Prerequisite to install appium 2 is to have node.js version 14+ and NPM 8+ version. Appium 2.0 can't be installed using npm install -g appium, it still install appium 1.x because version 2 is still in beta release. So we can install appium 2 using npm install -g appium@next but with this command drivers and plugins are not installed.
Appium 2.0 decouples its supported WebDrivers, hence we can choose to install only required drivers and plugins. For Android we can install UiAutomator2 and for iOS we can install XCUITest driver with appium driver install uiautomator2 and appium driver install xcuitestcommands respectively. Driver can be updated by appium driver update and driverName is the name of the driver as printed in the output of appium driver list --installed.
The project is using Appium java-client 7.6.0 as Maven dependency. I've also checked that there are no conflicts regarding HttpClient dependency (using same as java-client's which is 4.5.13 ).
Considering the support for multiple languages by Appium choosing Java becomes obvious since Java is the most common language used by mobile testers and quality assurance professionals for automation. The Appium Java client currently has the most robust Appium functionality.
When it comes to your test script, the only thing which differentiates the client (sometimes called driver) object from the client for a different test, is the session ID. All the client libraries automatically save the session ID when a session is started and include in in the path for all further commands. This is the only state a client object needs to keep, and we can take advantage of this to unlock some useful flexibility.
I, and others, have run into many cases where we want to control an automation session which is already in progress, but cannot share the client object itself. Sometimes I will have a Java test script paused halfway through a test in debugging mode, and want to connect my Javascript REPL to quickly try out some commands in the current app state. I can't pass the Java client object to my Javascript REPL, but I can easily copy and paste the session ID into my REPL and connect the client.
Another use case testers run into is when, for some reason driven by necessity, part of a test run is operated in a different scope. It could be you want to duplicate the client object and pass it to another thread, or maybe you are recovering from an error where the driver object has been destroyed but you need to delete the session on the server still. Maybe you are in a very unfortunate position where your test codebase is split across projects and you need to continue your session in another language entirely.
For most clients this trick is very easy. The clients have a method for getting the current session ID, and another accessible field for setting the session ID. There are examples of how to do this online for most of the clients, but the Java solution is particularly difficult. Years ago, it was relatively easy, but recent updates have made it trying.
I'm working on a pull request to the Appium Java client to add a new constructor which make this very easy. I wasn't able to finish in time for this article, but next week the following constructor should be available for all to use:
This results in a client object which will send commands to the given session ID, without starting a new session. Notice we don't need desired capabilities, since the session has already been started. If you need to get the desired capabilities which created the session, they are returned by the getAllSessionDetails() method.
This was much trickier to implement than I bargained for: the Selenium client which the Appium client extends attempts to create a new session as part of the constructor. Since we want to connect to an existing session, we have to skip this initialization. I ended up taking a slightly different approach but could have saved myself some frustration if I had read this great explanation of the code involved posted by Tarun Lalwani.
Appium is a completely free-to-use mobile automated testing framework. It is available as a Node package and also as a desktop app. We basically download the Appium server, but the client-side coding is done in a variety of programming languages. To learn more about the client-server architecture of Appium, refer to our post on Appium architecture.
In this post, we're going to show you how to install and set up Appium on macOS. We will also talk about the client-side setup in different languages. Finally, by the end of the post, we'll help you start writing test cases.
In this post, we showed how to set up Appium on Mac, starting with installing Java, Node, and Carthage. After that, we walked through setting up Appium in two ways, setting up Xcode and Android Studio, and checking all of these setups with Appium Doctor. Finally, we proceeded to do the client setup and write test cases.
The Appium client libraries wrap standard Selenium client libraries. Further it provide all the regular selenium commands dictated by the JSON Wire protocol, and add extra commands related to controlling mobile devices. Examples includes multi-touch gestures and screen orientation.
These client libraries implement the Mobile JSON Wire Protocol, and elements of the W3C Webdriver spec. In general, a transport-agnostic automation spec, this is where the MultiAction API is defined).
