Test Architect Quality Assurance Lead Interview Questions and Answers

Use a CSV parser library to extract data from CSV files.

• Use a CSV parser library like Apache Commons CSV or OpenCSV to read and extract data from CSV files.

• Identify the structure of the CSV file (e.g. delimiter, headers) to properly parse the data.

• Iterate through the CSV file to extract the desired data fields.

• Handle any data formatting or transformations needed during extraction.

• Store the extracted data in a suitable data structure for further processing.

Run-time polymorphism is the ability of a method to do different things based on the object it is acting upon.

• Run-time polymorphism is achieved through method overriding in inheritance.

• It allows a subclass to provide a specific implementation of a method that is already provided by its superclass.

• An example of run-time polymorphism is when a parent class reference variable is used to refer to a child class object.

Singleton pattern is a design pattern that restricts the instantiation of a class to one object.

• Singleton pattern ensures that a class has only one instance and provides a global point of access to it.

• It is commonly used in scenarios where only a single instance of a class is needed, such as managing database connections or configuration settings.

• In a test automation framework, singleton pattern can be used to create a single instance of a driver object for browser automation...read more

Test data is managed through a combination of manual and automated processes. Automation framework is designed using BDD and Selenium.

• Test data is created and maintained in a separate database or spreadsheet

• Automated scripts are designed to pull test data from the database or spreadsheet

• Data is randomized or parameterized to ensure test coverage

• Automation framework is designed using BDD principles to ensure collaboration between developers and testers

• Selenium is used as the p...read more

Extract letters, digits, and special characters from a string and display as individual strings

• Use regular expressions to extract letters, digits, and special characters

• Split the string based on the extracted characters

• Store the individual strings in an array

To reduce flakiness in a testing framework, implement robust strategies for stability and reliability in test execution.

• Use explicit waits instead of implicit waits to handle dynamic content loading.

• Implement retries for flaky tests to determine if failures are consistent or intermittent.

• Isolate tests to ensure they do not depend on the state of other tests, using setup and teardown methods.

• Regularly review and refactor tests to eliminate unnecessary complexity and improve ma...read more

TESTNG listeners are used to customize the test execution process and perform actions before or after test methods.

• TESTNG listeners can be used to perform actions before or after a test method, class, suite, or all tests.

• Listeners can be used to generate logs, take screenshots, or perform any custom actions during test execution.

• Some commonly used listeners in TESTNG are IInvokedMethodListener, ITestListener, and ISuiteListener.
