To store data in a textbox, use locators and line of code.

• Identify the textbox element using locators such as ID, name, class, or XPath

• Use the sendKeys() method to enter data into the textbox

• Store the data in an array of strings for later use

Maven is a build automation tool used primarily for Java projects. It manages dependencies and builds the project.

• Maven uses a Project Object Model (POM) to manage dependencies and build process

• Maven has a hierarchical structure with parent and child projects

• Maven plugins can be used to extend its functionality

• Maven can be integrated with Continuous Integration tools like Jenkins

• Example: mvn clean install command is used to build and package a project

TestNG is a testing framework for Java. It is used to perform unit, functional, integration, and end-to-end testing.

• TestNG is an open-source testing framework for Java

• It supports various types of testing such as unit, functional, integration, and end-to-end testing

• TestNG provides annotations to define test methods, test suites, and test cases

• It generates test reports and allows parallel execution of tests

• TestNG can be integrated with other tools such as Selenium and Maven

Assert checks if a condition is true, while verify checks if a condition is true and reports if it is false.

• Assert is used to validate the expected result of a test case

• Verify is used to validate the actual result of a test case

• Assert throws an exception and stops the test execution if the condition is false

• Verify reports the failure but continues with the test execution

• Assert is used for critical validations, while verify is used for non-critical validations

Manual testing involves executing test cases manually without the use of automation tools.

• Identify test scenarios and create test cases

• Execute test cases and record results

• Report defects and retest after fixes

• Perform regression testing

• Ensure test coverage and traceability

Method overloading is having multiple methods in the same class with the same name but different parameters. Method overriding is having a method in a subclass with the same name and parameters as a method in the superclass.

• Method overloading is achieved within the same class by having multiple methods with the same name but different parameters.

• Method overriding occurs in a subclass when a method has the same name and parameters as a method in the superclass, effectively rep...read more

Count the number of words and their frequency

• Split the given text into words using whitespace as delimiter

• Create a dictionary to store the word frequency

• Iterate through each word and update the frequency in the dictionary

• Return the dictionary with word frequency

Implementing the comparator function for sorting an array of strings.

• Use the built-in sort() function in most programming languages.

• Define a custom comparator function that compares two strings.

• Return a negative value if the first string should come before the second, a positive value if it should come after, and 0 if they are equal.

• Example: ['apple', 'banana', 'cherry'] can be sorted in alphabetical order using the comparator function.

Objects in Java can be created using the 'new' keyword, constructors, and factory methods.

• Use the 'new' keyword followed by the class name to create an object

• Objects can also be created using constructors to initialize the object's state

• Factory methods can be used to create objects without exposing the instantiation logic

Count the frequency of characters in a given string.

• Iterate through the string and use a hash map to store the count of each character.

• Initialize the count of each character to 0 and increment it as you encounter the character.

• Finally, iterate through the hash map to get the frequency of each character.

Test case template for QA testing

• Test case ID

• Test case description

• Test steps

• Expected result

• Actual result

• Pass/Fail status

Hard assert stops the test execution when a failure occurs, while soft assert continues the test execution after logging the failure.

• Hard assert is used when a failure should stop the test immediately.

• Soft assert is used when a failure should be logged but the test should continue.

• Example: Hard assert - assert.assertEquals(actual, expected); Soft assert - softAssert.assertEquals(actual, expected); softAssert.assertAll();
