10+ Accenture QA Engineer Interview Questions and Answers

Interview questions for QA Engineer

• Reverse a string using StringBuilder or StringBuffer

• Find second highest number by sorting the array and accessing the second last element

• String is immutable while StringBuffer is mutable

• HashMap stores key-value pairs while HashSet stores only keys

• Instance variables are declared inside a class while local variables are declared inside a method

The testing process involves verifying that software meets requirements and functions correctly.

• Testing involves creating test cases based on requirements

• Different types of testing include unit testing, integration testing, and regression testing

• Testing can be manual or automated, depending on the project and resources available

Slow scrolling in Selenium can be caused by various factors like large DOM, inefficient locators, or network latency.

• Check if the page has a large DOM structure which can slow down scrolling

• Optimize locators to make them more efficient and reduce the time taken to find elements

• Consider network latency as a possible cause for slow scrolling

• Use actions class in Selenium for smooth scrolling operations

Handling multiple windows in Selenium involves switching between windows and performing actions on each window.

• Use getWindowHandles() to get all window handles

• Switch to a specific window using switchTo().window(handle)

• Perform actions on the window

• Switch back to the original window if needed

Test automation framework consists of different parts like libraries, tools, and utilities.

• Libraries: reusable code modules for common functions

• Tools: software used for test automation like Selenium, Appium

• Utilities: additional resources for test automation like data generators, loggers

Bug cycle in Agile refers to the process of identifying, reporting, fixing, and verifying bugs during the development cycle.

• Bug cycle involves identifying bugs through testing

• Bugs are reported to the development team

• Developers fix the bugs

• QA engineers verify the fixes

• This cycle continues until all bugs are resolved

Regression testing is the process of retesting a software application to ensure that new code changes have not adversely affected existing functionality.

• Performed after code changes to ensure existing functionality still works

• Helps catch bugs introduced by new code changes

• Automated tools can be used to streamline the process

• Can be time-consuming but is essential for maintaining software quality

Automation testing is faster, more reliable, and scalable compared to manual testing.

• Automation testing is faster as it can execute tests much quicker than manual testing.

• Automation testing is more reliable as it eliminates human errors and ensures consistent test results.

• Automation testing is scalable as it can run tests on multiple configurations and environments simultaneously.

• Manual testing is better suited for exploratory testing and usability testing where human judgmen...read more

Use Java Stream API to sort HashMap by values.

• Use entrySet() method to get a set view of the mappings contained in the map.

• Use Comparator.comparing() to compare the values of the entries.

• Use sorted() method to sort the entries based on the comparator.

• Collect the sorted entries into a LinkedHashMap to maintain the order.

Selenium Architecture is a framework that consists of different components like Selenium IDE, WebDriver, and Selenium Grid.

• Selenium IDE: Record and playback tool for creating test scripts

• WebDriver: API for writing test scripts in various programming languages

• Selenium Grid: Distributes test execution across multiple machines for parallel testing

Synchronization in Selenium ensures that the automation script waits for the web page to load completely before performing actions.

• Selenium provides implicit, explicit, and fluent wait for synchronization.

• Implicit wait sets a default waiting time for the elements to be found.

• Explicit wait allows the script to wait for a certain condition to occur before proceeding.

• Fluent wait is a more flexible way of waiting for elements based on specific conditions.

• Example: driver.manage()....read more

Test scenarios for payment processing

• Verify payment is processed successfully with valid credit card information

• Test payment failure scenarios such as incorrect CVV, expired card, insufficient funds

• Check for proper error messages displayed to the user in case of payment failure

• Test payment processing speed under different network conditions

• Verify payment confirmation email is sent to the user after successful transaction

Xpath is a way to locate elements on a web page using their XML path.

• Xpath stands for XML Path Language.

• It is used in Selenium to locate elements on a web page.

• Xpath can be used to navigate through the elements and attributes in an XML document.

• There are two types of Xpath: Absolute and Relative.

• Example: //input[@id='username'] - locates an input element with id 'username'.

SDLC stands for Software Development Life Cycle, a process used by software development teams to design, develop, and test high-quality software.

• SDLC is a structured process that consists of several phases including planning, analysis, design, implementation, testing, and maintenance.

• Each phase has its own set of activities and deliverables that contribute to the overall success of the software project.

• Examples of SDLC models include Waterfall, Agile, and DevOps, each with it...read more

STLC stands for Software Testing Life Cycle, which is a systematic approach to testing software.

• STLC involves planning, designing, executing, and reporting on tests throughout the software development lifecycle.

• It includes phases like requirement analysis, test planning, test design, test execution, and test closure.

• Each phase has specific objectives and deliverables to ensure the quality of the software product.

• STLC helps in identifying defects early in the development proce...read more

Various tools are used in the project for testing purposes.

• Selenium for automated testing

• JIRA for bug tracking

• Postman for API testing

OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.

• OOPS focuses on creating objects that interact with each other to solve problems

• Key principles include encapsulation, inheritance, polymorphism, and abstraction

• Encapsulation involves bundling data and methods that operate on the data into a single unit

• Inheritance allows a class to inherit properties and behavior from another class

• Polymorphism enables o...read more
