The interview question includes locating xpaths, using waits in Selenium, and scenario-based questions.

• To locate xpaths, use the findElement() method with By.xpath() as the locator strategy.

• Waits in Selenium are used to synchronize the test execution with the application's state. Use explicit waits with ExpectedConditions for better control.

• Scenario-based questions require analyzing and solving real-life testing scenarios. Provide practical examples and demonstrate problem-so...read more

• Catch SQL Exceptions in try-catch blocks

• Log the error details for troubleshooting

• Handle exceptions gracefully to prevent application crashes

Regression is the process of retesting previously tested functionalities to ensure that new changes have not affected the existing features.

• Re-running test cases that were previously executed to verify that new code changes have not introduced any defects

• Ensuring that the microwave oven still functions correctly after any updates or modifications

• Testing all the basic functionalities like heating, defrosting, timer, etc. to confirm they are working as expected

Print tables from 1 to 20 in one sequential order.

• Use a loop to iterate from 1 to 20

• Inside the loop, multiply the current number with each number from 1 to 10

• Print the result in a formatted table

Different environments refer to various platforms or setups where software is tested or deployed.

• Development environment: where software is developed

• Testing environment: where software is tested

• Staging environment: where software is prepared for production

• Test case for navigating to different pages using keyboard shortcuts

Run time driver calling function is a mechanism where a function is called during the execution of a program.

• Run time driver calls a specific function based on certain conditions or events during program execution.

• This mechanism is commonly used in software testing to simulate real-world scenarios.

• Example: A test script that triggers a function to validate user input during runtime.

Finding a critical security vulnerability in a financial application

• Discovered a flaw in authentication process allowing unauthorized access

• Reported the issue to the development team and provided detailed steps to reproduce

• Received recognition for identifying a high-risk vulnerability

Regression is the process of retesting previously tested functionality to ensure that changes or fixes have not introduced new defects.

• Regression testing is performed to validate that existing functionality still works correctly after changes have been made.

• It helps identify any unintended side effects or bugs introduced by new code changes.

• Regression testing can be done manually or through automated testing tools.

• Examples of regression testing include running a suite of test...read more

Challenges in testing include time constraints, changing requirements, lack of resources, and complex systems.

• Time constraints can lead to rushed testing and potential oversights.

• Changing requirements can result in rework and delays in testing.

• Lack of resources such as skilled testers or testing tools can hinder the testing process.

• Complex systems with intricate interactions can make it difficult to identify and isolate bugs.
