  • SoapUI
  • Tricentis Tosca
  • Apigee
  • Jmeter

5. What are the core components of an HTTP request?

An HTTP request includes five key elements:

  • HTTP methods – Set of request methods to perform desired action for a given resource (GET, PUT, POST, DELETE)
  • Uniform Resource Identifier (URI) – Describes the resource
  • HTTP Version, (example- HTTP v1.1)
  • Request Headers, (example- Content-type : application/json, Content-Length : 511)
  • Payload – It is basically a Request Body which includes message content.

6. State The Core Components of an HTTP Response?

Every HTTP response contains four key elements.

  • Status/Response Code – These are response codes issued by a server to a client’s request. For example, 404 means Page Not Found, and 200 means Response is OK.
  • HTTP Version – describes HTTP version, for example-HTTP v1.1.
  • Response Header – Includes information for the HTTP response message. For example, Content-type, Content-length, date, status and server type.
  • Response Body – It contains the data that was requested by a client to server.

7. What API information is exposed in Web Developer tools?

Request headers, Response body, Response cookies

8. What can we use to get API information from web developer tools into Postman?

Copy as cURL can get API information from web developer tools into Postman.

9. In which type of encoding does postman accept authorization credentials?

Postman accepts Base64 encoding only. This is provided inbuilt in postman or else you can also refer 3rd party websites to convert the credentials in base64.

10. Why does Postman accept Base64 encoding only?

We use base64 particularly because it transmits the data into the textual form and sends it in easier form such as HTML form data. Also, we can rely on the same 64 characters in any encoding language that we use.

11. What is meant by the term environment in postman?

An environment in postman is a set of key value pairs. You can create multiple environments in postman which can be switched quickly with a press of a button. There are 2 types of environment, global and local.

12. Can global scope variables have duplicate names in postman?

Since global variables are global i.e. without any environment, global variables cannot have duplicate names. Local variables can have the same name but in different environments.

13. Which one will be preferred in postman- a global variable or a local variable?

In postman, if 2 variables have the same name( one being local, other global) then the higher priority is of the local variable. it will overwrite the global variable.

14. What is a Postman Collection?

A Postman Collection lets us group individual requests together. Simply it allows us to organize the requests into folders.

15. What do you mean by postman monitors?

The postman monitor is used for running collections. Collections are run till specified time defined by the user. Postman Monitor requires the user to be logged in. Monitor reports are shared by users over email on a daily/monthly basis.

16. What do you understand by the term Postman Collection runners?

A postman collection runner is used to perform Data-driven testing. The group of API requests are run in a collection for the multiple iterations with different sets of data.

17. Can local variables be imported in Postman Monitors?

Yes. Postman monitors allow to import local variables but it does not allow to import global variables.

18. What is the purpose of Postman cloud if we are working in a company? Why?

A Postman cloud is a common repository of companies to access Postman collections. In Postman cloud, work can be saved instantly after logging in. Anyone from the team can access data/collections from anywhere.

19. Why is it not preferred to save work in Postman cloud?

It is not preferred to save your work in Postman cloud as company’s work is not allowed to be leaked and remain confidential. Security breaches can be experienced if Postman cloud is used as Postman cloud requires sign in. Therefore Postman Cloud is discouraged for saving work and team workspace is highly encouraged.

20. What is the purpose of status code 304?

It means NOT MODIFIED. It is used to reduce network bandwidth usage in case of conditional GET requests. Response body should be empty. Headers should have date, location etc.

21. Define status code 201?

It means created, when a resource is successfully created using POST or PUT request. It returns a link to a newly created resource using the location header.

22. When do we use global variables, collection variables, and local variables?

Global variables are general purpose variables, ideal for quick results, and prototyping. They are used while passing data to other requests.

Collection variables can be mostly used for storing some constants that do not change during the execution of the collection. They are used for constants that do not change during the execution and also for URLs / authentication credentials if only one environment exists.

Local variables are only available within the request that has set them or when using Newman/Collection runner during the entire execution. They are used whenever you would like to override all other variable scopes.

23. How do you remove local variables?

Local variables are automatically removed once the tests have been executed.

24. How can we stop executing requests or stop the collection run?

postman.setNextRequest(null);

25. What is the difference between form data and x-www-form-urlencoded ?

The difference between the form data and x-www-form-urlencoded is that the url will be encoded when sent through x-www-form-urlencoded.

26. Where are query parameters stored in a GET request?

Query parameters are stored in the URL in a GET request.

5. Explain the Android Architecture with its components.

This is a popular android developer interview question

Android Architecture consists of 5 components that are-

a. Linux Kernel: It is the foundation of the Android Architecture that resides at the lowest level. It provides the level of abstraction for hardware devices and upper layer components. Linux Kernel also provides various important hardware drivers that act as software interfaces for hardwares like camera, bluetooth, etc.

b. Native Libraries: These are the libraries for Android that are written in C/C++. These libraries are useful to build many core services like ART and HAL. It provides support for core features.

c. Android Runtime: It is an Android Runtime Environment. Android Operating System uses it during the execution of the app. It performs the translation of the application bytecode into the native instructions. The runtime environment of the device then executes these native instructions.

d. Application Framework: Application Framework provides many java classes and interfaces for app development. And it also provides various high-level services. This complete Application framework makes use of Java.

e. Applications: This is the topmost layer of Android Architecture. It provides applications for the end-user, so they can use the android device and compute the tasks.

6. What are the services that the Application framework provides?

The Android application framework has the following key services-

a. Activity Manager: It uses testing and debugging methods.

b. Content provider: It provides the data from application to other layers.

c. Resource Manager: This provides users access to resources.

d. Notification Manager: This gives notification to the users regarding actions taking place in the background.

e. View System: It is the base class for widgets, and it is also responsible for event handling.

7. What are the important features of Linux Kernel?

The important features of the Linux Kernel are as follows:

a. Power Management: Linux Kernel does power management to enhance and improve the battery life of the device.

b. Memory Management: It is useful for the maximum utilization of the available memory of the device.

c. Device Management: It includes managing all the hardware device drivers. It maximizes the utilization of the available resources.

d. Security: It ensures that no application has any such permission that it affects any other application in order to maintain security.

e. Multi-tasking: Multi-tasking provides the users the ease of doing multiple tasks at the same time.

8. What are the building blocks of an Android Application?

This is a popular android interview question for freshers.

The main components of any Android application are- Activity, Services, Content Provider, and Broadcast Receiver. You can understand them as follows:

a. Activity- It is a class that acts as the entry point representing a single screen to the user. It is like a window to show the user interface.

b. Services- Services are the longest-running component that runs in the background.

c. Content Provider- The content provider is an essential component that allows apps to share data between themselves.

d. Broadcast receivers- Broadcast receiver is another most crucial application component. It helps the apps to receive and respond to broadcast messages from the system or some other application.

9. What are the important components of Android Application?

The Components of Android application are listed below:

  1. Widgets
  2. Intents
  3. Views
  4. Notification
  5. Fragments
  6. Layout XML files
  7. Resources

10. What are the widgets?

Widgets are the variations of Broadcast receivers. They are an important part of home screen customization. They often display some data and also allow users to perform actions on them. Mostly they display the app icon on the screen.

11. Can you name some types of widgets?

Mentioned below are the types of widgets-

a. Informative Widgets: These widgets show some important information. Like, the clock widget or a weather widget.

b. Collective Widgets: They are the collection of some types of elements. For example, a music widget that lets us change, skip, or forward the song.

c. Control Widgets: These widgets help us control the actions within the application through it. Like an email widget that helps check the recent mails.

d. Hybrid Widgets: Hybrid widgets are those that consist of at least two or more types of widgets.

12. What are Intents?

Intents are an important part of Android Applications. They enable communication between components of the same application as well as separate applications. The Intent signals the Android system about a certain event that has occurred.

13. Explain the types of intents briefly?

Intent is of three types that are-

a. Implicit Intents: Implicit intents are those in which there is no description of the component name but only the action.

b. Explicit Intents: In explicit intents, the target component is present by declaring the name of the component.

c. Pending Intents: These are those intents that act as a shield over the Intent objects. It covers the intent objects and grants permission to the external app components to access them.

14. What is a View?

A view is an important building block that helps in designing the user interface of the application. It can be a rectangular box or a circular shape, for example, Text View, Edit Text, Buttons, etc. Views occupy a certain area of the screen, and it is also responsible for event handling. A view is the superclass of all the graphical user interface components.

15. What do you understand by View Group?

It is the subclass of the ViewClass. It gives an invisible container to hold layouts or views. You can understand view groups as special views that are capable of holding other views, that are Child View.

16. What do you understand about Shared Preferences?

It is a simple mechanism for data storage in Android. In this, there is no need to create files, and using APIs, it stores the data in XML files. It stores the data in the pair of key-values. SharedPreferences class lets the user save the values and retrieve them when required. Using SharedPreferences we can save primitive data like- boolean, float, integer, string and long.

17. What is a Notification?

A notification is just like a message that shows up outside the Application UI to provide reminders to the users. They remind the user about a message received, or some other timely information from the app.

18. Give names of Notification types.

There are three types of notifications namely-

a. Toast Notification- This notification is the one that fades away sometime after it pops up.

b. Status Notification- This notification stays till the user takes some action on it.

c. Dialog Notification- This notification is the result of an Active Activity.

19. What are fragments?

A fragment is a part of the complete user interface. These are present in Activity, and an activity can have one or more fragments at the same time. We can reuse a fragment in multiple activities as well.

20. What are the types of fragments?

There are three types of fragments that are: Single Fragment, List Fragment, Fragment Transactions.

  1. Single Transactions can only show a single view for the user.
  2. List Fragments have a special list view feature that provides a list from which the user can select one.
  3. Fragment Transactions are helpful for the transition between one fragment to the other.

Frequently asked Android Interview Questions and Answers

Security breaches can be experienced if Postman cloud is used as Postman cloud requires sign in. Therefore Postman Cloud is discouraged for saving work and team workspace is highly encouraged.

20. What is the purpose of status code 304?

It means NOT MODIFIED. It is used to reduce network bandwidth usage in case of conditional GET requests. Response body should be empty. Headers should have date, location etc.

21. Define status code 201?

It means created, when a resource is successfully created using POST or PUT request. It returns a link to a newly created resource using the location header.

22. When do we use global variables, collection variables, and local variables?

Global variables are general purpose variables, ideal for quick results, and prototyping. They are used while passing data to other requests.

Collection variables can be mostly used for storing some constants that do not change during the execution of the collection. They are used for constants that do not change during the execution and also for URLs / authentication credentials if only one environment exists.

Local variables are only available within the request that has set them or when using Newman/Collection runner during the entire execution. They are used whenever you would like to override all other variable scopes.

23. How do you remove local variables?

Local variables are automatically removed once the tests have been executed.

24. How can we stop executing requests or stop the collection run?

postman.setNextRequest(null);

25. What is the difference between form data and x-www-form-urlencoded ?

The difference between the form data and x-www-form-urlencoded is that the url will be encoded when sent through x-www-form-urlencoded.

26. Where are query parameters stored in a GET request?

Query parameters are stored in the URL in a GET request.
