Android Studio and Xcode Basic Commands

Question 1

How are mobile testing and mobile app testing are different?

Answer 1

Mobile testing = testing functionalities of a mobile device.

Mobile app testing = testing apps running over mobile devices.

Question 2

Give an example of common mobile bugs and how you prioritizing it?

Answer 2

Testers work to find four types of common bugs; critical, block, minor, and major.

For example there, a phone system crash when testing a particular feature of the device will be classified as a critical bug.

Certain performance unavailability through the device is ON will fall into the block bug list.

The GUI bugs will be categorized as minor bugs.

Functional disability of a particular feature will be submitted to a major bug list.

Question 3

What are the types of mobile applications?

Answer 3

• Native apps are created for one specific platform or operating system.
• Web apps are responsive versions of websites that can work on any mobile device or OS because they’re delivered using a mobile browser.
• Hybrid apps are combinations of both native and web apps, but wrapped within a native app, giving it the ability to have its own icon or be downloaded from an app store.

Question 4

Native apps

Answer 4

Created for one specific platform or operating system.

Question 5

Web apps

Answer 5

Responsive versions of websites that can work on any mobile device or OS because they’re delivered using a mobile browser.

Question 6

Hybrid apps

Answer 6

Combinations of both native and web apps, but wrapped within a native app, giving it the ability to have its own icon or be downloaded from an app store.

Question 7

What according to you is the importance of Usability testing?

Answer 7

Usability testing is used to check if the app is user-friendly.

It involves analyzing customer’s behavior and experience on the application to identify bugs and discrepancies.

The metrics considered for usability testing are the design of the app, response time and how intuitive it is.

Question 8

What is the latest version of iOS?

Answer 8

iOS version 16 (I double checked to makes sure this is true)

Question 9

What is the latest version of Android?

Answer 9

Android 12

Question 10

What is the extension of Android files?

Answer 10

.apk (Android application package)

Question 11

How would you define AVD?

Answer 11

AVD stands for Android Virtual Device. It is an Android emulator to test applications on PCs.

Question 12

What is the extension of iOS files?

Answer 12

.ipa (iOS App Store Package)

Question 13

What all major networks to be considered while performing application testing?

Answer 13

You should test the application on 4G, 3G, 2G, and WIFI. 2G is a slower network, it’s good if you verify your application on a slower network also to track your application performance.

Question 14

What are the tools based on cloud-based mobile testing?

Answer 14

Perfecto Mobile, AWS Device Farm, BrowserStack, SauceLabs.

Question 15

What is the most common problem with the emulators according to you?

Answer 15

They often fail to capture the important attributes of a device. Also, they suffer a lot from the compatibility issues if no open source technology is considered.

Question 16

How would you define a good test case?

Answer 16

Good test case: Here is an example of a good test case: install and launch the application. Try to login with user info@interview.com with password “abcd”, wait 5 seconds for the app to respond and shows you the app interface after the login.

Question 17

How would you define a bad test case?

Answer 17

Bad test case: There can be two main bad test case scenarios. The first one would be very undescriptive, e.g. install, launch and login. In this case you don’t really know what to expect exactly from the test.

The other bad test case would be a test case that tries to test many different functionalities at the same time.
The result would be that you don’t concentrate on just one aspect of the app at a time and you might be missing other important functionality.

Question 18

On what metrics is the sanity test performed on mobile apps?

Answer 18

The sanity test on apps can be performed based on 5 metrics:
1. Performance on different devices.
2. Performance in various network environments.
3. Installation and update of apps.
4. If the app allows calls when running in the background.
5. Media compatibility.

Question 19

What is WAP?

Answer 19

WAP stands for Wireless Application Protocol. Used in network apps, this communication protocol enables data access through wireless networks.

It facilitates easy connectivity between mobiles and the internet and enhances wireless interoperability.

Question 20

How will you communicate app crashes to the developer?

Answer 20

I would start by identifying the scenario in which the app crashes.

Then I would use a defect tracking tool to report app crashing and attach screenshots with the error message.

I would also suggest steps to reproduce to bring app crashes in control.

Question 21

What would you do if your app works well on some devices and crashes on others?

Answer 21

I would conduct compatibility tests to analyze the application’s performance on multiple devices with different network environments.

This will help in the identification of the devices on which the app crashes.

I would try uninstalling and installing the app and if it still does not function properly, I would highlight the issue to the developer and suggest fixes.

Question 22

Can you name 2 apps for Android and 2 for iOS to record crash logs?

Answer 22

To record crash logs, you can use:

Android Studio and Eclipse for Android devices
and
iOS LogInfo and Xcode iOS device

Question 23

What are the most important mobile application test cases according to you?

Answer 23

In my opinion, the most important mobile app test cases are:
* Usability test case.
* Battery usage test case.
* app functioning test case.
* Touchscreen test case.
* Security test case.
