To validate text displayed in HTML tag, use automation tools like Selenium to locate the element and verify the text content.

• Locate the HTML element using appropriate locators like ID, class name, XPath, etc.

• Retrieve the text content of the element using getText() method.

• Compare the retrieved text with the expected text using assertion methods.

• Use automation tools like Selenium WebDriver to automate the validation process.

Utilized Java OOP concepts like inheritance, encapsulation, polymorphism, and abstraction in the automation framework.

• Inheritance: Created a base class 'TestBase' for common test setup and teardown methods, allowing derived classes to inherit these functionalities.

• Encapsulation: Used private variables in page object classes to hide implementation details, providing public getter and setter methods for access.

• Polymorphism: Implemented method overloading in utility classes to h...read more

Different types of asserts used in Selenium include assert, verify, and waitForAssert

• Assert: Stops the execution if the verification fails

• Verify: Continues the execution even if the verification fails

• waitForAssert: Waits for a certain condition to be true before proceeding

Background keyword and Dry tag are used in Cucumber for test automation.

• Background keyword is used to define a set of steps that are common to all scenarios in a feature file.

• Dry tag is used to define a set of steps that can be reused across multiple feature files.

• Background keyword is written at the beginning of a feature file, while Dry tag is written in a separate file.

• Background keyword is used to reduce code duplication and improve readability.

• Dry tag is used to improve ...read more

Test cases for automation should be selected based on their frequency of execution, complexity, and stability.

• Identify frequently executed test cases

• Select test cases with high complexity

• Choose stable test cases

• Consider test cases with high risk and impact

• Prioritize regression test cases

• Evaluate the feasibility of automating the test case

This program demonstrates how to call a GET API using Rest Assured and parse the response without JsonPath.

• Setup Rest Assured: Include Rest Assured dependencies in your Maven or Gradle project to use its features.

• Make GET Request: Use Rest Assured's given() method to specify the request and call the API with when().get().

• Parse Response: Use the Response object to get the response body as a String and manually parse it using standard Java methods.

• Example: String responseBody =...read more

The number of feature files will depend on the project requirements and the level of granularity in test scenarios.

• Number of feature files can vary based on the size and complexity of the project

• Each feature file typically represents a specific functionality or feature being tested

• Feature files can be organized based on modules, user stories, or test scenarios

Cypress enhances testing with built-in features, while raw JavaScript lacks testing-specific utilities and structure.

• Cypress provides a robust testing framework with built-in assertions and commands, making tests easier to write and maintain.

• Direct JavaScript lacks testing utilities; Cypress offers features like automatic waiting, which simplifies asynchronous testing.

• Cypress runs in the same run-loop as the application, allowing for real-time interaction and debugging, unlik...read more

Counting radio buttons on a page in Selenium using findElements method

• Use findElements method to locate all radio buttons on the page

• Get the size of the list of elements to count the number of radio buttons

To set up a project in Jenkins, follow these steps:

• Create a new project in Jenkins

• Configure the project settings, including source code management and build triggers

• Add build steps, such as running tests or deploying the application

• Save the project configuration

• Run the project to ensure it is set up correctly

Exceptions faced in Selenium

• StaleElementReferenceException

• NoSuchElementException

• TimeoutException

• ElementNotVisibleException

• ElementNotInteractableException

Java String, StringBuffer, and StringBuilder differ in mutability and memory storage, impacting performance and usage.

• String: Immutable; once created, cannot be changed. Example: String str = 'Hello'; str = str + ' World'; creates a new object.

• StringBuffer: Mutable; can be modified without creating new objects. Example: StringBuffer sb = new StringBuffer('Hello'); sb.append(' World');

• StringBuilder: Similar to StringBuffer but not synchronized, making it faster for single-thre...read more

Overview of Java 8 features, collections usage, automation frameworks, and CI/CD integration.

• Java 8 introduced lambda expressions for functional programming, e.g., `list.forEach(item -> System.out.println(item));`.

• Streams API allows processing collections in a functional style, e.g., `list.stream().filter(x -> x > 10).collect(Collectors.toList());`.

• Optional class helps avoid NullPointerExceptions, e.g., `Optional.ofNullable(value).ifPresent(v -> System.out.println(v));`.

• Colle...read more

Waits in Selenium are used to synchronize the test execution with the application's response.

• Implicit Wait

• Explicit Wait

• Fluent Wait

• Thread.sleep()

• WebDriverWait

No, a class cannot be an interface in programming.

• A class is a blueprint for objects, while an interface is a contract for classes to implement certain methods.

• A class can implement multiple interfaces, but it cannot extend multiple classes.

• Interfaces cannot have constructors or instance variables, while classes can have both.

We followed various problem-solving methods while using Selenium.

• Identifying the root cause of the issue

• Analyzing the logs and error messages

• Collaborating with developers to resolve issues

• Using debugging tools like Firebug and Chrome Developer Tools

• Check the test results to see if the feature file ran successfully

Test inputs include valid inputs, boundary values, invalid inputs, and edge cases.

• Valid inputs: Providing inputs within the valid range to ensure the program functions correctly.

• Boundary values: Testing inputs at the boundaries of valid ranges to check for any issues.

• Invalid inputs: Testing inputs outside the valid range to see how the program handles errors.

• Edge cases: Testing extreme or unusual inputs to uncover any unexpected behavior.

• Use swipe method to scroll vertically or horizontally on the screen

• Use scroll method to scroll to a specific element on the screen

• Use scrollTo method to scroll to a specific text on the screen

Files can be uploaded using API by sending a POST request with the file as a payload. UI can use file input field to upload files.

• For API, use a POST request with the file as a payload

• For UI, use a file input field to select and upload files

• API example: POST /uploadFile with file as payload

• UI example: to select and upload files

Implicit wait is set globally for all elements, while explicit wait is applied only to specific elements.

• Implicit wait is set once at the beginning of the test script

• Explicit wait is used for specific elements with different wait times

• Implicit wait is defined for the entire duration of the WebDriver object

• Explicit wait is defined for a specific condition or element to wait for
