It is commonly called the Instrumentation Test Runner and is basically a runner which is responsible for smoothly running the test case on an application package. The tools that offer API and the SDK tools are present in this runner and it is responsible for writing the programs that control the Android gadgets.
The use of mobile apps is becoming quite common and currently millions of apps are developed each day across the globe. Although they have different purposes and use, a few of the features are quite essential in all of them. This includes:
This is basically a procedure to simply test the same functionality on the other devices for understanding its behavior on the different platforms.
Well, Mobile apps are widely replacing the software. More and more people are utilizing their phones for performing various tasks. As their dependency on phones in increasing, there is probably nothing wrong to say that those apps are becoming more and more common. The good thing is these days apps are capable to perform all the tasks that were once restricted to a PC by making use of the software. Also, apps can be deployed for business enlargement and several other enterprises need fulfillment.
In-network applications, WAPI has important applications. It stands for Wireless Application Protocol and plays a significant role in assuring the reliability of the network and the good thing is, it makes sure that applications can be deployed to other platforms for testing purposes very easily.
There are several testing tools available. You can answer this question based on those who have experienced with or you have used it. The common ones are Image-Based Mobile Testing tools and Object-Based Mobile Testing Tools.
These are Integration Test, Unit Test, System Test, as well as Operation Test. Depending on the use and the features of a mobile application, there is another test also which is generally performed in this environment.
The application package simply means the target application which needs to be tested for finding various errors, performance parameters, and other important information regarding an application.
The two calluses are named Mock Objects, as well as the Test Case Classes. This includes the test methods and mock data for sample tests and for inputs. The users can modify the same depending on the overall complexity of the program or the code they are working on. Sometimes the Test Package has to deploy the application on another platform than the one it is based on and these classes are useful during such an approach.
This can be a higher-level question for those who haven’t exposed the mobile application testing with different technologies. However, you can answer this question simply by telling the interviewer about the following practices which are common
The very first one is storing the test cases together with the source code. The next one is assuring that the rooted devices (devices on which a customized OS has been installed as Android is an open-source technology) should be avoided. The third one is to build the test cases at the same time when the codes are written by the developer and the fourth one which is rare is making use of continuous integration and executing the test whenever there is a change in the code is noticed.
There are many things that can go wrong with a mobile application and all the bugs couldn’t be categorized under the same headline. Some of the common ones are crashing the phone OS during the test of a particular feature on the phone. Not able to perform any task on the phone, GUI, bugs, a specific feature of an application is not operating (this is very common). In addition to this, the other ones are:
It is not always easy to perform the test on the Android Framework for the device. This is because it takes a lot of time, as well as efforts to build different test cases and developing the strategies. Thus, the Robo-electric approach simply lets the users run the Android test without depending o a simulator.
The most common problem is the high cost which is obvious in the cloud. Next issue that declares their presence because of uncertain internet connectivity. Problems related to the subscription models and the lock-in situations are also critical to deal with. Moreover, there are sometimes restrictions on automation when it comes to using the same outside the framework.
They often fail to capture the important attributes of a device. Also, they suffer a lot from compatibility issues if no open source technology is considered.
It is basically a type of software testing in which there is a micro group of end-users takes part. It is generally done to find the defects which are related to the usability of the application in the mobile environment. One of the main aims of this test is to make sure that users can easily use the app under all conditions. Generally, attention is given to the application flexibility and controls of the apps. The other name of this testing is User Experience Testing
Different types of mobile app testing as follows:
[ Related Blog: What are the Types of Software Testing ]
Standard Android testing strategy as follows:
Simulator is basically electronic equipment which is widely adopted in mobile application and other testing environments. It is also considered as a base station for the testing of an app for all its features and behavior before it is actually made available for public use on the concerned platforms. The apps are generally developed on simulators before the actual development takes place.
Well, the term compatibility has wide use and scope when it comes to application testing. It simply means the ability to survive together with something similar. Compatibility testing is quite common and it is basically a type of testing that assures the ability of an application to run on different Operating Systems, platforms, networks, as well as on hardware. It is also considered non-functional testing.
Detecting the areas which are sensitive in applications.
As the name itself indicates, it is basically a test that is done to make sure what sort of performance an application offer when the same is made run under a load which is more than what it can actually handle or tolerate. Here it really doesn’t matter what type of function and the features are supported by the software under concern. One of the main aims in this testing is not to find the errors that affect the functionality but to find parameters that can enhance the performance of the app. This is how it is different from any other testing technique. The other name of this testing is Perf Testing.
Mobile application testing tracking tools:
These are Services Testing, Interference testing, Low-level Resource Testing, Usability testing, Security testing, as well as Operational testing.

Platform Testing and second is Device Testing.
There is nothing wrong to say that security largely matters and it is one of the major factors that device the overall number of users. The fact is applications have to deal with a lot of information about the users and this often includes some personal data. Therefore, security test matters a lot and it simply makes sure to the users that the application can simply be trusted.
It totally depends upon the project to project, can you please elaborate on the question because this is project-specific as starting from installation and version upgrade, uninstallation, etc we do apart from functional testing. Security and Performance of applications also need to be tested.
Sometimes some issue appear on particular version device and OS of the device also do matter.
Generally, the issue depends upon the different OS/device version, it might be the same thing is working on one OS while it might not work on another version. The example we faced an issue that our application was working fine on iOS 6.x version devices but on tapping a few modules on iOS 5.x devices application crashes and same happened with 2.3.5 Vs
In the very first test we have to perform installation, after that we check the basic functionality and after that, we check the connectivity-related stuff of the application, Then we uninstall the build and verify how application responds when we interrupt during installation and also we check interruption scenarios when our application request network call.
We also do low network/poor connectivity testing during network calls. Upgrade from older version to newer version. navigation in the application without a network if it supports this feature. Compatibility of the app on different kind of phones like having external buttons & devices do not have external buttons or other than this flip phone etc
The issue is saving a contact on phone memory or deleting it or sometimes a conference call issue while an active call is there n like that.
This is of the same nature as any other software testing project using any tool like Jira, Bugzilla, etc
We generally divide the modules among the team members and then shuffle the modules among team members with different devices.
They are generally categorized into three types and they are:
Web Application, Native Application, and the third is Hybrid Application.
Yes, there are certain factors that the users have to pay attention to. The very first thing is to make sure that the installation of every tool has been taken place properly. The next thing to pay attention to is to assure the launch of the application when no network is available.
Next is to pay attention to the orientation of the app which sometimes needs users to simply uninstall the same. After this, the users have to make sit sure that the performance of the application is up to the mark when it is made run on a different device and noting down the response.
The common ones are Test Studio, Appium, and iPad Peek.
The monkey procedure is the one that simply makes sure that the users are able to access the configuration options without facing any problem. It also simply makes sure of the availability of all the debugging options. Moreover, users can get an idea of the operational constraints easily.
The very first thing that the test automation tool has is the support for multi-platform so that even the future needs of the users could easily be fulfilled. The overall usability of the script should be high and the tool must have some basic or advanced jailbreak requirements.
This is because there are users who often install a customized ROM on their devices and the violation of MDM policies often creates issues. Next is the ability of the tool to support the new versions of the OS. If possible, the tool should be capable of sharing the source code.
Either the application needs to be tested multiple times or when it has new functionality.
We have to test the application on 2G/EDGE, 3G, and Wifi network because some times application faces issues on slower networks.
