Regression is the process of retesting previously tested functionalities to ensure that new changes have not affected the existing features.

• Re-running test cases that were previously executed to verify that new code changes have not introduced any defects

• Ensuring that the microwave oven still functions correctly after any updates or modifications

• Testing all the basic functionalities like heating, defrosting, timer, etc

Absolute Xpath starts from the root element, while relative Xpath starts from any node in the DOM structure.

• Absolute Xpath starts with a single forward slash (/) and starts selection from the root node.

• Relative Xpath starts with a double forward slash (//) and starts selection from the current node or any node in the DOM structure.

• Absolute Xpath is more brittle and prone to breaking if the structure of the page changes...read more

The return would be the number of tabs open in the browser.

• The return value would be an integer representing the count of open tabs.

• For example, if there are 5 tabs open, the return value would be 5.

Types of waits in Selenium include Implicit Wait, Explicit Wait, and Fluent Wait.

• Implicit Wait: Waits for a certain amount of time before throwing a NoSuchElementException.

• Explicit Wait: Waits for a certain condition to occur before proceeding further in the code.

• Fluent Wait: Waits for a condition to be true with a defined polling frequency.

• Example: driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Exceptions in Selenium are errors that occur during test execution, disrupting the flow of the test script.

• Exceptions are thrown when there is an unexpected behavior in the application under test or in the test script itself.

• Common exceptions in Selenium include NoSuchElementException, ElementNotVisibleException, TimeoutException, and StaleElementReferenceException.

• Handling exceptions in Selenium can be done using try-...read more

Feature files contain high-level description of the functionality to be tested, while step definitions are the implementation of the steps in the feature file using code.

• Feature files are written in Gherkin syntax and describe the behavior of the application in plain text.

• Step definitions are written in programming languages like Java, Ruby, etc., and map the steps in the feature file to automation code.

• Feature files a...read more

Data can be input in Cucumber using feature files and step definitions.

• Data can be input in feature files using scenarios and scenario outlines

• Step definitions can be used to define the actions to be taken with the input data

• Data tables can be used in feature files to input structured data

• Examples keyword can be used in scenario outlines to provide multiple sets of input data

Test case is a set of conditions or variables under which a tester will determine whether a system under test satisfies requirements. Test plan is a document outlining the scope, approach, resources, and schedule of testing activities. Test scenarios are detailed descriptions of possible interactions with the system.

• Test case: specific conditions to be tested, expected results, steps to execute

• Test plan: overall strate...read more

Hooks in Java are methods that allow subclasses to override or extend the behavior of a superclass.

• Hooks are commonly used in frameworks like JUnit and TestNG for test automation.

• They are often used for setup and teardown operations before and after test methods.

• Examples include @Before, @After, @BeforeClass, and @AfterClass annotations in JUnit.

A Java program to count the occurrences of the letter 'l' in the string 'Hello world'.

• Create a Java program with a main method.

• Initialize a String variable with the value 'Hello world'.

• Use a loop to iterate through each character in the string and count the occurrences of the letter 'l'.

• Print the count of 'l' at the end.

Reverse the characters of each word in a given string

• Split the input string into an array of words

• Reverse each word in the array

• Join the reversed words back into a single string

Comparator is an interface used to sort objects, while Comparable is an interface used to compare objects for natural ordering.

• Comparator is used to define custom sorting logic for objects, while Comparable is used for natural ordering based on the class's implementation of compareTo() method.

• Comparator can be used to sort objects of different classes, while Comparable is implemented within the class itself.

• Example: So...read more

Lambda expression is a concise way to represent an anonymous function in programming languages.

• Lambda expressions are used to create small, inline functions without a formal definition.

• They are commonly used in functional programming languages like Python, Java, and C#.

• Lambda expressions can be used to simplify code and make it more readable.

• Example: (x, y) -> x + y is a lambda expression that takes two parameters a

Constructor chaining is the process of calling one constructor from another constructor in a class.

• Allows reusing code and avoiding duplication

• Can be achieved using 'this' keyword in the constructor

• Helps in initializing objects with different parameters

Handle notifications in mobile automation by using automation tools to interact with notifications, verify content, dismiss or respond to them.

• Use automation tools like Appium or Espresso to interact with notifications

• Verify the content of notifications by extracting text or images

• Dismiss notifications to continue with test execution

• Respond to notifications if required for test scenarios

• Handle different types of notifi...read more

Use platform-specific locators or conditional statements to handle different element xpaths in iOS and Android apps.

• Use platform-specific locators like accessibility id for iOS and resource id for Android

• Implement conditional statements to switch between different xpaths based on the platform

• Utilize Appium's platformName capability to identify the platform and adjust the element xpath accordingly

TestNG annotations include @Test, @BeforeMethod, @AfterMethod, @BeforeClass, @AfterClass, @BeforeSuite, @AfterSuite

• @Test - denotes a test method

• @BeforeMethod - runs before each test method

• @AfterMethod - runs after each test method

• @BeforeClass - runs before the first test method in the current class

• @AfterClass - runs after the last test method in the current class

• @BeforeSuite - runs before all tests in the suite

• @AfterSu
