10+ Bajaj Finserv QA Automation Engineer Interview Questions and Answers

I am using the Selenium WebDriver framework for automation testing.

• Selenium WebDriver is a popular open-source framework for automating web applications.

• It supports multiple programming languages such as Java, Python, C#, etc.

• It provides a rich set of APIs for interacting with web elements and performing actions.

• It also supports parallel execution and integration with other tools like TestNG and Maven.

• I have used it to automate testing for various web applications such as e-c...read more

The @BeforeMethod and @AfterMethod annotations are used for opening and closing the browser.

• The @BeforeMethod annotation is used to open the browser before each test method.

• The @AfterMethod annotation is used to close the browser after each test method.

• These annotations are part of the TestNG framework.

• Example: @BeforeMethod public void setUp() { //code to open browser } @AfterMethod public void tearDown() { //code to close browser }

Regression testing ensures that changes to the code do not affect existing functionality. Sanity testing checks if the critical functionalities are working after a small change.

• Regression testing is done after making changes to the code to ensure that existing functionalities are not affected.

• Sanity testing is done after a small change to ensure that critical functionalities are still working.

• Regression testing is done after every major change, while sanity testing is done af...read more

We use multiple environments including development, testing, staging, and production.

• Development environment for coding and testing new features

• Testing environment for automated and manual testing

• Staging environment for final testing before deployment

• Production environment for live usage

• Each environment is isolated and has its own database and configurations

• We also use virtual environments for testing different operating systems and browsers

Failed test cases can be executed by identifying the root cause of failure and fixing it before re-executing the test case.

• Identify the root cause of failure by analyzing the test results and logs

• Fix the issue causing the failure

• Re-run the test case to ensure it passes

• Update the test case status and report any defects found

• Repeat the process for all failed test cases

API testing involves verifying the functionality, reliability, performance, and security of APIs.

• Identify the API endpoints and their expected behavior

• Create test cases to cover all possible scenarios

• Use tools like Postman, SoapUI, or JMeter to send requests and validate responses

• Verify the response status codes, headers, and payload

• Test for security vulnerabilities like SQL injection or cross-site scripting

• Automate API tests using frameworks like Selenium or RestAssured

Yes, but it may not always be the most efficient or reliable method.

• Xpath can be used to locate elements on any website, but it may require some trial and error to find the correct path.

• Other methods such as CSS selectors or ID attributes may be more efficient in some cases.

• Xpath can also be affected by changes to the website's structure or layout.

• Using browser developer tools can help in identifying the correct xpath for an element.

SDLC is the process of developing software while STLC is the process of testing software.

• SDLC includes planning, designing, coding, testing, and maintenance stages while STLC includes test planning, test case development, test execution, and test closure stages.

• SDLC focuses on the development of software while STLC focuses on the testing of software.

• SDLC is a broader term that includes STLC as a part of it.

• SDLC is a continuous process while STLC is a sequential process.

Annotations are used in Java to provide additional information about classes, methods, and fields.

• Annotations are declared using the @ symbol followed by the annotation name.

• Annotations can have attributes that can be set using key-value pairs.

• Annotations can be applied to classes, methods, fields, parameters, and local variables.

• Annotations can be inherited from superclasses or interfaces.

• Annotations can be used for documentation, code analysis, and runtime processing.

• Some c...read more

Selenium waits are used to synchronize the test script execution with the web application's response time.

• Selenium waits are used to handle synchronization issues in test automation.

• There are three types of waits in Selenium: Implicit, Explicit, and Fluent waits.

• Implicit waits wait for a certain amount of time before throwing an exception if the element is not found.

• Explicit waits wait for a certain condition to occur before proceeding with the next step.

• Fluent waits wait for...read more

Postman tool allows different parameters to be used for API testing.

• Query Parameters: Used to filter and sort data in the API response.

• Path Parameters: Used to identify a specific resource in the API.

• Header Parameters: Used to provide additional information about the request.

• Body Parameters: Used to send data in the request body.

• Form Data Parameters: Used to send data in the form of key-value pairs.

• Environment Variables: Used to store and reuse values across requests.
