UPDOER Technology QA Engineer Interview Questions, Process, and Tips

Manual testing is the process of manually testing software for defects without the use of automation tools.

• Involves executing test cases manually without automation tools

• Requires human intervention to verify software functionality

• Involves exploratory testing to uncover defects

• Can be time-consuming but allows for flexibility and creativity in testing

• Examples: regression testing, ad-hoc testing, usability testing

STLC stands for Software Testing Life Cycle, which consists of various stages for ensuring the quality of software.

• STLC stands for Software Testing Life Cycle

• It consists of stages like Requirement Analysis, Test Planning, Test Design, Test Execution, and Test Closure

• Each stage has specific objectives and deliverables

• Example: In Requirement Analysis, testers analyze the requirements and create test scenarios

Regression, Sanity, and Smoke testing are different types of testing performed at different stages of the software development lifecycle.

• Regression testing is performed to ensure that new code changes have not adversely affected existing functionality.

• Sanity testing is a subset of regression testing and is performed to quickly determine if a new build is stable enough for more rigorous testing.

• Smoke testing is performe...read more

Functional Testing focuses on testing the functionality of the software, while Regression Testing ensures that new changes do not affect existing functionality.

• Functional Testing verifies that the software functions as expected based on the requirements.

• Regression Testing ensures that new code changes do not negatively impact existing functionality.

• Functional Testing is typically done before Regression Testing in the s...read more

A test plan is a document outlining the scope, approach, resources, and schedule for testing a software application.

• Identify test objectives and scope

• Define test strategies and methodologies

• List resources and tools required for testing

• Outline test schedule and milestones

• Specify test cases and scenarios

• Include risk assessment and mitigation plan

Monkey testing is a random testing technique where the application is tested with random inputs to uncover unexpected bugs.

• Involves randomly clicking buttons, entering data, and performing other actions in the application

• Helps in uncovering bugs that may not be found with traditional testing methods

• Can be automated using tools like Selenium with random input generators

The main method in Java is the entry point for any Java application.

• Main method must be declared as public static void main(String[] args)

• It is the starting point for the execution of a Java program

• It is where the program begins its execution

Five common exceptions in Java programming language

• NullPointerException - occurs when trying to access a method or property of a null object

• ArrayIndexOutOfBoundsException - occurs when trying to access an index outside the bounds of an array

• ArithmeticException - occurs when dividing by zero

• FileNotFoundException - occurs when trying to access a file that does not exist

• ClassCastException - occurs when trying to cast an o

Five major exceptions encountered in automation testing

• NoSuchElementException

• TimeoutException

• StaleElementReferenceException

• ElementNotVisibleException

• ElementNotInteractableException

Automating dynamic location involves using relative locators and dynamic xpath to identify elements.

• Use relative locators to find elements based on their relationship to other elements

• Utilize dynamic xpath to locate elements that have changing attributes or values

• Implement wait strategies to handle dynamic loading of elements

Program to reverse a string and reverse a specific word in the string.

• Create a function to reverse a string by iterating through each character and appending it to a new string in reverse order.

• Create a function to reverse a specific word in the string by splitting the string into words, finding the specific word, and reversing it.

• Combine the two functions to reverse the entire string and a specific word within it.

Use SQL query to find the third largest salary in Employee table.

• Use ORDER BY clause to sort salaries in descending order

• Use LIMIT to get the third row

• Consider handling ties if multiple employees have the same salary
