Types of wait mechanisms include implicit wait, explicit wait, fluent wait, and thread.sleep.

• 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.

• Fluent wait: Waits for a condition to be true with a specified polling frequency.

• Thread.sleep: Pauses the execution for a specified amount of time.

Frames in Selenium can be managed using switchTo() method to navigate between frames.

• Use driver.switchTo().frame() method to switch to a frame by index, name or WebElement

• Use driver.switchTo().defaultContent() method to switch back to the main content

• Use driver.switchTo().parentFrame() method to switch to the parent frame

Use a Set data structure to remove duplicates from an array of strings.

• Create a Set from the array to automatically remove duplicates

• Convert the Set back to an array to get the unique values

List, Set, and Map are different types of collections in Java used to store and manipulate groups of objects.

• List is an ordered collection that allows duplicate elements. Example: ArrayList, LinkedList

• Set is a collection that does not allow duplicate elements. Example: HashSet, TreeSet

• Map is a collection of key-value pairs where each key is unique. Example: HashMap, TreeMap

I would analyze the user stories and application functionality to identify the root cause of the mismatch and work towards resolving it.

• Review the user stories and application functionality to understand the discrepancies

• Communicate with stakeholders to clarify requirements and expectations

• Update test cases and automation scripts to align with the corrected user stories

• Collaborate with developers to address any underly

To count URLs in an HTML page using Selenium and open the URL containing your name, you can use a combination of Selenium WebDriver methods and regular expressions.

• Use Selenium WebDriver to navigate to the HTML page and retrieve its source code

• Use regular expressions to identify and count the URLs in the source code

• Iterate through the list of URLs to find the one containing your name

• Use Selenium WebDriver to open the U

Use regular expressions to separate letters and digits from a string in Java.

• Use the String class's split() method with a regular expression to separate letters and digits.

• Create a regular expression pattern that matches either letters or digits.

• Store the separated letters and digits in separate arrays.

Defect life cycle is the process of identifying, reporting, fixing, retesting, and closing defects in software development.

• Defect identification: Defects are identified through testing or user feedback.

• Defect reporting: Defects are reported in a defect tracking tool with details like steps to reproduce, severity, and priority.

• Defect fixing: Developers fix the reported defects based on the information provided.

• Defect re...read more

Black box testing focuses on functionality without knowledge of internal code, while white box testing examines internal code structure.

• Black box testing tests the functionality of a system without knowledge of its internal code

• White box testing tests the internal code structure and logic of a system

• Black box testing is more focused on end-user perspective

• White box testing is more focused on developer perspective

• Exampl...read more

Hard assert stops the execution of the test case if it fails, while soft assert continues the execution and logs the failure.

• Hard assert is used when the failure of a particular step makes the further steps irrelevant.

• Soft assert is used when you want to continue with the test case execution even if some steps fail.

• Hard assert is implemented using 'assert' keyword in testing frameworks like TestNG or JUnit.

• Soft assert ...read more

Annotations in Selenium WebDriver are used to provide additional information about the test methods.

• Annotations help in organizing and managing test cases

• Some common annotations in Selenium WebDriver are @Test, @BeforeTest, @AfterTest, @BeforeClass, @AfterClass, @BeforeMethod, @AfterMethod

• Annotations are used to define the sequence of execution of test methods

Use XPath to count the number of links with the text 'selenium'

• Use XPath to locate all the links containing the text 'selenium'

• Count the number of links found using the XPath expression

Use SQL query to display 60 pass and 40 fail from a table of students.

• Use SELECT statement with COUNT function to count the number of pass and fail statuses.

• Use WHERE clause to filter out pass and fail statuses.

• Use GROUP BY clause to group the statuses together.

• Use CASE statement to display the count of pass and fail statuses.

The output of the code will be 'animal is created' followed by 'Dog is created'.

• The code defines a class Animal with a constructor that prints 'animal is created'.

• It also defines a class Dog that extends Animal, with a constructor that prints 'Dog is created'.

• In the main method, an instance of Dog is created, which will trigger the constructors of both Animal and Dog classes.

The output will be 'HelloThere'

• Concatenation of 'Hello' and 'There' results in 'HelloThere'

• The final string is printed using System.out.println()

The code creates a StringBuffer object with 'Hello' and appends 'There' to it before printing the final string.

• StringBuffer is mutable, so the original 'Hello' string can be modified

• The append() method adds the specified string to the end of the buffer

• The final output will be 'HelloThere'

Option a is valid, option b is valid, option c is invalid.

• Option a is valid because ChromeDriver is a subclass of WebDriver, so it can be assigned to a WebDriver reference.

• Option b is valid because ChromeDriver is a subclass of WebDriver, so it can be instantiated using a WebDriver reference.

• Option c is invalid because WebDriver is an interface and cannot be instantiated directly. It can only be used as a reference typ

Sort input array of strings in descending order without using inbuilt functions

• Iterate through the array and compare each element with the rest to find the largest element

• Swap the largest element with the first element, then repeat the process for the remaining elements

• Continue this process until the array is sorted in descending order

findElement returns the first matching element on the page, while findElements returns a list of all matching elements.

• findElement returns a single WebElement matching the locator provided

• findElements returns a list of WebElements matching the locator provided

• findElement will throw NoSuchElementException if no element is found, while findElements will return an empty list
