HR Revealed Automation Interview Questions For Freshers

1. What is the difference between Manual Testing and Automation Testing?

Tests conducted by testers manually is called Manual Testing, wherein they compare the expected and actual functionality are in accordance with the test cases.

Tests conducted by using software tool is called Automation Testing, wherein the expected results are fed into the tool to be compared with the actual output of software being tested.

2. What are the prerequisites to start automation testing?

Following are the prerequisites for starting automation testing:

Stable build
List of repeated functionality
List of Test Data
iAutomation Framework

3. Explain the procedure followed in Automation Testing?

Tool Selection – List down the automation tools compatible, depending on whether the application is Desktop / Web based, language used for software development etc

Scope of Automation – List down the scenarios and functionality which are repetitive and automatable

Planning – Design a framework, Schedule the scripting and execution of the same

iDevelopment – Scripting the scenarios to be tested with inputs(Test Data) and expected output

Execution – Running/Executing the scripts and reporting the results

vMaintenance – Update the scripts in accordance to the latest changes with the software under test

4. What are the different types of Automation Testing?

Unit tests, GUI tests and Functional tests

Unit tests – Done at development phase which helps reduce the bugs

GUI tests – Done at testing level, which focuses its scripts to test user interface of application under test

Functional tests – Done at testing level, which simulates the functional scenarios to test the application with provided input and expected results

NOTE : Other automation test include Webservice testing

5. What are the Advantages of Automation Testing

Reduced test execution time
Can be executed in cross platforms test cases (different OS, browsers, environment, etc)
Simplifies complex functional tests
Automating repetitive tasks

6. What are the Disadvantages of Automation Testing

Continuous script maintenance/updation is necessary
Basic programming knowledge is a must for better automation test
Expensive
Skilled resources required for scripting

7. Why use a particular tool for automation testing ?

Tool selection should be done considering –

Platform to be tested – like supported OS, scripting languages supported by tool and testing
environment
Debugging facility
Support for object identification
Frameworks supported

8. What are the aspects considered while shortlisting test cases for Automation?

Following cases should be automated :

GUI cases
Regression cases
Most repeated scenarios
Tests with multiple data sets

9. What are the factors to prove the maximum usage of automation testing?

Following are the criteria considered to prove maximum usage of automation testing :

Number of test cases to defect detected ratio
Execution time and time required to release the product
Reduction in manual interference
Complexity of Maintenance
Test coverage

10. What are the Popular tools used for automation testing?

HP UFT(Formerly QTP)
Rational Robot
IBM Rational Functional Tester
Selenium

11. Conditions when we can’t consider automation testing

Conditions considered to be disadvantageous when automating a test are :

Ever changing requirements
Documentation required is exhaustive
Only suitable for continuous integration
One time test cases
Adhoc : Random testing

12. What is Automation Framework?

It is a set of standard rules followed by a company to structure the test automation of an application. Wherein the supporting scripts, data sheets and reports are organized and put together for easier access and maintenance.

13. What are the different types of Automation Frameworks?

Most popular and used Automation frameworks are :

Data Driven Testing Testing Framework
Keyword Driven Testing Framework
Hybrid Driven Testing Framework
Behavior Driven Development Framework

14. What are the Advantages of Automation Framework?

Ease of maintenance
Simplifying the process followed
Adherence to standard
Re-usability
Complete coverage
vEasier future enhancements

15. What is Data Driven Testing Framework?

Major usage of automation testing is to simplify the testing process involving complex and huge data sets by documenting the same, which will be used as input to testing tools.

In Data Driven Testing Framework, the test data which includes input, expected output and a result field are listed in files like CSV files, excel files, text files, XML files etc. These files are fed to automation tool for execution, which in turn compares the expected and actual data. Logs the result of each test data into result field.

16. What is Keyword Driven Testing Framework?

The keywords and locators required to locate an element by automation tool are listed in files like CSV files, excel files, text files, XML files etc. These files act as input to automation tool for element detection. Keywords and locators are updated regularly to keep up with application changes, hence the maintenance becomes difficult with unstable applications.

17. What is Hybrid Driven Testing?

Hybrid Driven is combination of both Data Driven and Keyword Driven Testing Framework, most of the company adopt Hybrid Driven Testing Framework for better utilization automation tool. Related data sets and element keywords are documented and fed as input to automation tool.

18. What are the Standards followed for scripting?

Following are the standards considered while scripting,

Uniformity in naming convention.
Commenting the functionality whenever and wherever necessary
Adequate indentation.
Robust error handling and ability to recovery
Use of Frameworks

19. Have you used any customized automation testing tool?

There are many companies which develop in-house testing tools for in-depth testing of applications, list out some if your company uses any. An example of same is customized Selenium for load testing. It should be able to explain basic flow or framework used to implement the customized tool effectively.

20. Is documentation required in Test Automation?

Documentation plays a critical role in Test Automation. Practices should be documented, so that they are repeatable. Specifications, designs, configurations, code changes, automation plan, test cases listed for automation, bug reports, user manuals should all be documented.
