Polaris Consulting Selenium Automation Interview Questions, Process, and Tips

Priority in TestNG determines the order in which test methods are executed.

• Priority can be set using the 'priority' attribute in @Test annotation

• Default priority is 0, higher priority is executed first

• Priority can be negative as well

• If two methods have the same priority, they are executed in alphabetical order

A simple Java program is a standalone program while a Maven project is a build automation tool.

• A simple Java program is compiled and executed using the command line or an IDE.

• A Maven project uses a pom.xml file to manage dependencies and build the project.

• A simple Java program may require manual management of dependencies.

• A Maven project can easily manage dependencies and build the project with a single command.

• A simpl...read more

Tags are used in Cucumber to organize and filter scenarios and features.

• Tags allow for easy organization of scenarios and features based on their purpose or functionality.

• Tags can be used to filter which scenarios or features are run during a test.

• Tags can be added to scenarios or features using the '@' symbol followed by the tag name.

• Tags can also be used to pass parameters to step definitions.

• Examples: @smoke, @regre

TestNG is more advanced and flexible than JUnit, with features like parallel testing and data-driven testing.

• TestNG supports parallel testing while JUnit does not.

• TestNG allows for data-driven testing while JUnit does not.

• TestNG has more advanced annotations and reporting features than JUnit.

• TestNG can be used with both Java and non-Java languages while JUnit is only for Java.

• JUnit is simpler and easier to learn than T

To disable a test, we can comment out the test code or use testNG annotations.

• Comment out the test code

• Use testNG annotations like @Test(enabled=false)

• Use testNG XML file to disable the test

• Use groups to disable a set of tests

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.

• Start from the first element and compare it with the next element

• If the next element is smaller, swap them

• Repeat this process for all elements in the array

• Continue this process until no more swaps are needed

A program to print all prime numbers

• Take input from user for range of numbers

• Loop through the range and check if each number is prime

• Print the prime numbers

Hashmap is a data structure that stores key-value pairs and allows constant time access to values based on their keys.

• Hashmap uses a hash function to map keys to indices in an array.

• Collisions can occur when multiple keys map to the same index, which can be resolved using techniques like chaining or open addressing.

• Examples of hashmap implementations include Java's HashMap class and Python's dict type.

Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

• Inheritance allows code reuse and promotes code organization.

• The existing class is called the parent or superclass, and the new class is called the child or subclass.

• The child class inherits all the properties and methods of the parent class and can also add new properties and methods.

• For...read more
