Interview Questions.

Q1. What Is Input Injection And What Are Different Ways Of Doing It ?

Input Injection:  It is the act of simulating user input, in numerous ways you could simulate user input.

Direct Method Invocation

Invocation the use of an accessibility interface

Simulation using low-degree enter

Simulation using a device driver

Simulation the usage of a robot

Q2. Mention What The Main Areas To Be Taken In Consideration While Writing Api Document ?

The key area to be taken into consideration whilst writing API documents are:

Source of the content

Document plan or cartoon

Delivery layout

Information required for each feature within the document

Automatic report advent programs

Q3. What Are The Main Challenges Of Api Testing?

The main demanding situations in API testing is:

Parameter Selection

Parameter Combination

Call sequencing

Q4. What Are The Tools Used For Api Testing?

The tools used for diverse API checking out are:

SoapUI Pro

LoadUI Pro

Alertsite API tracking

Q5. What Are The Tools Used For Api Test Automation?

While checking out Unit and API checking out,  each target supply code, if an API method is the usage of code  based totally on .NET then the tool that is helping have to have .NET

Automation gear for API checking out can be used are:

NUnit for .NET

JUnit for Java

HP UFT

Soap UI

Q6. What Is Api Testing?

API (Application Programming Interface) specifies how some software program components need to interact with different, in different phrases it’s a fixed of capabilities and methods that permits the introduction of packages which get admission to the features or information of an utility or working device.   Testing of those capabilities is called API trying out.

Q7. What Are The Common Protocols That Are Testing In Api Tesing ?

HTTP

JMS

REST

SOAP

UDDI

Q8. Explain What Is Rest Api?

It is a fixed of capabilities to which the builders plays requests and acquire responses. In REST API interplay is made via HTTP protocol

REST – stands for Representational State Trfer, it's far quickly becoming defacto widespread for API creation.

Q9. In Api Document Explain How To Document Each Function ?What Are The Tools Used For Documentation?

Description: Small description approximately what a characteristic does

Syntax: Syntax approximately the parameter of the code, the collection wherein they arise, required and elective elements and so forth.

Parameters: Functions parameters

Error Messages: Syntax of error messages

Example Code: Small snippet of code

Related Links: Related capabilities

Popular equipment used for API documentations are JavaDoc (for Java code ) Doxygen (for .Net code)

Q10. Difference Between Api And Unit Testing?

API checking out:

API is owned via QA group

API is commonly black field testing

Full functionality of the system is taken into consideration in API checking out as it could be used by the quit-person (outside developers who will use your API )

API check are regularly run after the build is ready and authors do now not have get entry to to the source code. 

UNIT trying out:

Unit testing is owned via improvement group 

Unit testing is white field trying out

Unit checking out is carried out to affirm whether every unit in isolation plays as predicted or now not

For each in their module the builders are expected to construct unit checks for each of their code modules and should make sure that every module bypass unit test before the code is covered in a build.
 

Q11. What Is Api Testing With Runscope ?

Runscope is an internet software that offers backend offerings and smooth to use interface for checking out APIs.

Q12. What Are The Types Of Bugs Will Api Testing Finds?

The forms of Bugs, API will find:

Missing or reproduction capability

Fails to deal with error situations gracefully

Stress

Reliability

Security

Unused flags

Not applied errors

Inconsistent blunders handling

Performance

Multi-threading issues

Improper errors

Q13. Mention The Steps For Testing Api ?

API trying out steps:

Select the test case that has to be fulfilled

For API call increase a take a look at case

To meet the test case configure the API parameters

Determine how can you validate a a success take a look at

Using programming language like PHP or .NET execute the API name

Allow the API name to return the records to validate.

Q14. Explain Api Framework?

API framework is self-explanatory. Values for check run and for holding the configurable elements, config document is used.  Automated take a look at cases have to represent in “ parse-desk” format inside config document.  When checking out API, it isn't always essential to test each API so the config record have a few phase whose all API are activated for that unique run.

Q15. Explain What Is Testapi ?

TestApi is a library of utility and check APIs that allows testers and builders to create checking out equipment and automatic tests for .NET and Win32 software.  It gives a hard and fast of common test constructing blocks, kinds, statistics-structure and algorithms.

Q16. Mention The Key Difference Between Ui Level Testing And Api Testing?

UI ( User Interface) refers to checking out graphical interface together with how consumer interacts with the applications, testing software factors like fonts, pictures, layouts and many others. UI trying out essentially focuses on appearance and feel of an application.

While, API permits communique among two separate software systems. A software gadget enforcing an API incorporates functions or sub-exercises that may be done via every other software program device.

Q17. How Does The Api Builder Work?

API Builder is a PLSQL application includes four SQL files:

For placing API parameters and beginning the process one file is responsible

Two files are created for brief tables and Master bundle to create the outputted code

Fourth report creates “spooled” output of the code right into a file known as “output_script_.Square”.

Q18. Explain What Is Soap?

SOAP-stands for Simple Object Access Control, and it is an XML based protocol for exchanging facts between computers.

Q19. Explain What Are The Principles Of Api Test Design?

The precept for API take a look at layout are:

Setup : Create gadgets, start services, initialize information and so forth

Execution: Steps to workout API or scenario, additionally logging

Verification: Oracles to assess execution final results

Reporting: Pass, failed or blocked

Clean up: Pre-take a look at state
