Overloading is when multiple methods have the same name but different parameters. Overriding is when a subclass provides a different implementation of a method inherited from its superclass.

• Overloading is used to create multiple methods with the same name but different parameters.

• Overriding is used to provide a different implementation of a method in a subclass.

• Overloading is resolved at compile-time based on the method signature.

• Overriding is resolved at runtime based on the...read more

Playwright can wait for elements implicitly through various actions and conditions without explicit wait commands.

• Playwright automatically waits for elements to be ready before performing actions, such as clicking or typing.

• For example, using `page.click('selector')` waits for the element to be visible and enabled.

• When navigating to a new page, Playwright waits for the page to load completely before proceeding.

• Using assertions like `expect(locator).toBeVisible()` also implici...read more

Run time driver calling function is a mechanism where a function is called during the execution of a program.

• Run time driver calls a specific function based on certain conditions or events during program execution.

• This mechanism is commonly used in software testing to simulate real-world scenarios.

• Example: A test script that triggers a function to validate user input during runtime.

Regression is the process of retesting previously tested functionality to ensure that changes or fixes have not introduced new defects.

• Regression testing is performed to validate that existing functionality still works correctly after changes have been made.

• It helps identify any unintended side effects or bugs introduced by new code changes.

• Regression testing can be done manually or through automated testing tools.

• Examples of regression testing include running a suite of test...read more
