Test automation is a critical component in the realm of software testing, streamlining the verification process and ensuring the delivery of high-quality software. When delving into interview discussions about test automation, candidates are often assessed on their understanding of automation frameworks, scripting languages, testing tools, and overall proficiency in automating repetitive testing tasks.

1. Explain test automation.


Test automation is the process of testing software applications with specialized software tools. The automation tools perform pre-scripted tests, compare actual results with predicted outcomes, and provide complete test reports instead of manually executing test cases. This method guarantees effective software defect identification while expediting the testing process.

2. What makes test automation necessary?


Test automation is essential to meet the demands of modern software development, where frequent upgrades and releases are the norm. Automation increases productivity by quickly running test cases and facilitating faster code modification feedback. Because the same set of tests can be conducted again, it encourages repeatability by lowering the possibility of human mistakes.

3. Does Selenium WebDriver mean what?


Web applications can be automated with the powerful tool Selenium WebDriver. Operating as an interface for programming enables users to engage with many web components and carry out tasks. Many computer languages, such as Java, Python, C#, and others, are supported by this automation tool, which is frequently used for online testing.  

4. Which locator types are there in Selenium WebDriver?


Selenium WebDriver recognizes and interacts with web components using a variety of locators. These consist of XPath, CSS Selector, ID, Name, Class Name, Tag Name, Link Text, and Partial Link Text.

  • The Selenium method findElement aims to locate and return the first element on a web page that satisfies the given criteria.
  • Perfect for Individual Components: It works especially well when you need one matching piece.

Find elements In Selenium: 

  • Provides a List: Unlike `findElement, `findElements yields a list or collection that includes every web element that meets the requirements.
  • Useful for Multiple Elements: You can interact with each matching element on the web page as needed with this method, which is helpful when dealing with circumstances when there are multiple of them.

7. How should dynamic items be handled in Selenium?


Managing dynamic elements on a web page can be difficult because their properties can change while the page is being rendered. Using CSS selectors with partial matching or dynamic XPath, where attributes are partially matched, is how Selenium handles dynamic elements. Furthermore, relative locators—which locate items based on their relationship with neighbouring elements, independent of changing attributes—are introduced in Selenium 4 and provide a more reliable method for managing dynamic elements. These methods improve Selenium scripts’ ability to adjust to dynamic web content.

8. What is the definition of TestNG?


Inspired by JUnit and NUnit, TestNG is a powerful Java testing framework. It has parallel test running, configuration, and thorough test reporting features. Software testing professionals frequently utilize TestNG because it provides a strong and adaptable environment for managing test suites and running tests.

9. What do TestNG annotations mean?


Special techniques called annotations are used in TestNG to regulate how tests are executed. Several annotations are included in this list, such as @Test, @BeforeMethod, @AfterMethod, @BeforeClass, and more. For example, a method can be marked as a test case with @Test. @BeforeMethod and @AfterMethod run before and after each test method, and @BeforeClass and @AfterClass run once before and after the complete test class.

10. What benefits can utilizing a framework driven by keywords offer?


  • Improved Cooperation:  Enables communication and coordination between team members with and without technical expertise.
  • Accessibility for Non-Programmers: Allows test participants with subject knowledge but need more programming experience to participate.

  • Compares pointers to objects.
  • Determines whether two pointers lead to the same chunk of memory.
  • Frequently employed for comparison of references and primitive types.

The.equals() method: 

  • compares an object’s values or content.
  • Used to override the Object class’s default equals() behaviour.
  • It is crucial to compare content meaningfully, particularly when implementing custom classes.

12. In TestNG, what is a Data Provider?


One useful component that allows parameters to be sent to test methods is TestNG’s Data Provider. This feature improves test coverage and enables more extensive testing, making it easier to run the same test with various data sets. TestNG is a flexible tool for testing different scenarios with varied input values since it incorporates Data Providers, which allows parameterization.

13. What is a Framework for Test Automation?


An organized set of principles and procedures known as a test automation framework helps to improve and expedite the process of automating tests. It includes object repository administration, test script organization, coding standards, and test data handling procedures. A framework’s major objective is to give automation a standardized, scalable approach that improves the effectiveness and maintainability of the testing process.

14. Describe what the Page Object Model (POM) is.


A popular design pattern in web application test automation is the Page Object Model (POM). Every web page should have an object repository created for it, with all of the page’s elements represented as variables in a corresponding class. This modular strategy isolates page-specific information within their classes, which enhances code reusability and maintainability. The Page Object Model encourages a distinct division of labour between test logic and page structure and improves the readability of test scripts.
