29. Can automation testing completely replace manual testing?

No, automation testing cannot completely replace manual testing.

Automation testing requires human intervention for setting up the environment. Automation testing is good for long large and repeated testing tasks. For newer scripts and rarely executed tests, automation testing is hard of any use. 

30. How will you determine which test cases you will pick for automation testing?

We will consider the following criteria for picking up test cases for automation testing:

  1. The frequency of executing the test cases is one of the major criteria in deciding whether to select the test case for automation testing or not. The higher the frequency of re-running the test cases more viable it is for automation testing. 
  2. Find out whether automating the test case would save you time or not.
  3. The criticality of the test case is another major decision whether to automate the test case or not. 
  4. The automation testing of the test case should not exceed the time required to execute the test case manually
  5. Consider the criticality of the test case in deciding if to automate it or not. the more critical test cases are better to be automated. 

31. Which types of test cases will you not automate?

We will not automate the following test cases:

  • Usability tests generally require manual intervention to check the test results
  • Test cases that include setup 
  • Test cases that re not to be repeated
  • Test cases that return unpredicted test results
  • UX tests 
  • exclude unplanned and random test cases 

32. Describe the automation testing lifecycle?

The stages of automation testing are.

  1. Decide whether to automate testing or not
  2. Identify the Automation tool
  3. Recognize the scope of automation testing
  4. Design and development of a test suite
  5. Continuous test execution 
  6. Maintain test suite

33. Describe your plan for automation testing of web applications?

Irrespective of the choice of your automation tools like SilkTest, QTP, Selenium or any other test tool you can follow the following rules

  •       Web UI testing.
  • Have a unique name for every web page.
  • Follow uniform naming scheme for similar objects.
  • No two objects should have the same name.
  • Every image should have an ALT attribute set.
  • Dynamic content must have a proper name, ID or XPath.
  • Data tables should have specific names.
  • Cross-browser stability.
  •       Web service layer (Rest/Soap) testing.
  • API Request/Response verification.
  • API error code testing.
  • Web service XSD validation.
  • Cross-server validation.

34. What are the advantages and disadvantages of automation testing at the UI layer?

  •       Advantages of automation testing in UI layer
  • It helps to validate end-to-end UI flows.
  • Helps in the integration of the testing application with the external systems.
  • It allows giving test suite to the customer to gather his feedback 
  • Helps in getting early feedback on high priority modules 
  • It helps in the early revealing of severe bugs.
  • Tests UI functionality even when it cannot be done manually.
  •       Disadvantages of automation testing in UI layer
  • UI automation can break for frequently changing UI element locators.
  • Slow Test execution.
  • Only limited information can be verified.
  • You have to limit the number of test cases because of slow test execution.
  • It is time demanding involving many steps.

35. Which test automation strategy would you prefer for your agile software?

For the Agile methodology, the pyramid approach has been proven quite successful. It divides the complete cycle into three levels.

  • The base or the first level belongs to unit tests
  • Next is the service layer including API tests. 
  • The last and the topmost is GUI testing.

Using it testers can test the complete application. Each layer of the pyramid has its own significance and as a whole, the complete pyramid results in complete testing of the system. 

36. Tell me about the automation framework in general?

The automation framework is a software platform that provides the needed structure and echo system to automate and run test cases. They are also a set of rules for users for efficient automation testing.

Some of the rules are:

  • Rules for writing test cases.
  • Coding rules for developing test handlers.
  • Prototype for Input test data.
  • Management of Object repository.
  • Log configuration.
  • Usage of Test results and reporting.

37. State a few coding practices to follow during automation?

Some of the best coding practices for test automation are:

  • Reusable test handlers’ development that is put in a separate file.
  • Add comments whenever fixing a bug.
  • Follow standards set by the programming language being used.
  • Store test data in an external data source.
  • Run test scripts regularly.

38. State the scripting standard for automation testing? 

The scripting standards for writing scripts for automation testing are: 

  • Naming convention should be uniform.
  • For every 10 lines of code, there should be a 3 Lines of comments 
  • There should be proper indentation.
  • There should be robust error handling and recovery scenario
  • Use Frameworks whenever possible

39. Explain Sikuli? 

Sikuli uses the “Visual Image Match” method for automating the graphical user interface. Sikuli takes images as input for all its web elements. It consists of 

  • Sikuli Script
  • Visual Scripting API for Jython
  • Sikuli IDE

It is used to

  • automate flash websites or objects
  • It automates window based application without using internal API support
  • Offers simple API
  • Easy to link with tools like Selenium
  • Can automate Desktop application 
  • Extensive support to automate flash objects
  • uses “Visual Match” and Flash objects to automate desktop
  • works on multiple technologies -.NET, Java,

40. What is your next step after identifying your automation test tool?

The next step would be to design a framework.

41. What are the characteristics of a good framework?

The characteristics of a good framework are:

42. Why do you keep URL, Login, and passwords in a separate file and not directly in the code?

These pieces of information are used very frequently, if we hardcode them into the code, we will require to change them in every file they are referred in.

Therefore such information is stored in a separate file.

43. What is the main reason for testers to refrain from automation? How can they overcome it?

The main reason that holds back the testers from automation testing is to learn programming language/coding. To overcome this, they can:

  • Collaborate with developers for automation
  • Automation is not only testers job, but it is also a combined team effort
  • Give dedicated time for automation.
  • Get management support whenever needed.

44. Name important modules of automation testing Framework?

Important modules for automation testing framework are:

  • Test Assertion Tool
  • Data setup
  • Build Management Tool
  • Continuous integration tool
  • Reporting tool
  • Logging tool

45. What are the advantages of the Modular Testing framework?

The advantages of Modular Testing Framework are:

  • Easy to maintain
  • scalability of test cases
  • can create test scripts using already scripted modules

46. What are the disadvantages of the keyword-driven testing framework?

The disadvantages of the keyword-driven testing framework:

  • It is more complicated 
  • Test cases get longer and complex 

47. Can we do automation testing without a framework? If yes, how?

Yes, automation testing can be done without a framework. Understand the tool and program the steps in the programming language supported by the tool.

48.  Which tools are you well-acquainted with?

List out the tools you have used, however, make sure that you have experience in handling Selenium

49. Can we automate CAPTCHA or RECAPTCHA?

Nope, not possible. You can either enable or disable it in the test environment.

50.  When do you go for manual rather than automated testing?

Exploratory tests, usability testing, ad-hoc testing, etc require tester skills rather than technical skills. So these testing requires manual intervention rather than automation.
