Java program for array reverse, recursion, balanced parenthesis using stack, constructor usage, and defect life cycle in testing.

• Array reverse: Use a for loop to swap elements from start to end.

• Recursion: A method that calls itself to solve a problem.

• Balanced parenthesis using stack: Push opening brackets onto stack and pop when closing brackets are encountered.

• Constructor in Java: Used to initialize objects of a class.

• Smoke testing defect life cycle: Identifying defects in i...read more

Overloading is having multiple methods in the same class with the same name but different parameters. Overriding is implementing a method in a subclass that is already defined in the parent class.

• Overloading allows a class to have multiple methods with the same name but different parameters.

• Overriding is when a subclass provides a specific implementation of a method that is already provided by its parent class.

• Example of overloading: public void print(int a) and public void p...read more

Selenium locators include ID, Name, Class Name, Tag Name, Link Text, Partial Link Text, CSS Selector, and XPath.

• Types of Selenium locators include ID, Name, Class Name, Tag Name, Link Text, Partial Link Text, CSS Selector, and XPath.

• XPath is used when other locators are not suitable or when locating elements based on complex conditions.

• Types of XPath include Absolute XPath and Relative XPath.

• Example: driver.findElement(By.xpath("//input[@id='username']"));

Test plan is a document that outlines the testing approach and objectives. Test strategy is a high-level plan for achieving the testing goals.

• Test plan includes details about test scope, test environment, test cases, and test schedules.

• Test strategy defines the testing methodology, tools, and techniques to be used.

• Test plan is created by the test manager or lead, while test strategy is created by the project manager or business analyst.

• Test plan is a more detailed document th...read more

A local variable is a variable that is declared within a specific function or block of code and can only be accessed within that scope.

• Local variables have limited scope and are only accessible within the function or block where they are declared.

• Local variables are typically used for temporary storage of data within a specific function.

• Local variables are created when the function is called and destroyed when the function completes its execution.

Pointers are variables that store memory addresses of other variables in programming languages like C and C++.

• Pointers allow direct access to memory locations

• They are used for dynamic memory allocation

• Pointers can be used to pass variables by reference

• Example: int *ptr; ptr = # // ptr now points to the memory address of num

Software testing is the process of evaluating a software application to ensure its quality and functionality.

• Software testing is done to identify defects or errors in the software.

• It involves executing test cases and comparing the actual results with expected results.

• Testing can be performed manually or using automated tools.

• Types of software testing include functional testing, performance testing, security testing, etc.

• Example: Testing a login functionality by entering valid...read more

Acceptance testing is a type of testing that determines whether a software system meets the requirements and expectations of the stakeholders.

• It is performed to ensure that the software meets the business requirements and is ready for deployment.

• It is usually performed by the end-users or the customer.

• It can be done manually or through automation.

• It is the final stage of testing before the software is released.

• Examples include User Acceptance Testing (UAT) and Operational Acc...read more

Positive testing is a testing technique where valid inputs are given to the system to check if it behaves as expected.

• Valid inputs are given to the system

• Expected behavior is checked

• It is also known as 'Happy Path Testing'

• Example: Entering a valid username and password to log in

A walk through software testing involves step-by-step examination of the software to identify defects and ensure quality.

• Start by reviewing the requirements and creating test cases based on them.

• Execute the test cases to identify defects in the software.

• Report and track the defects found during testing.

• Retest the defects after they have been fixed to ensure they are resolved.

• Conduct regression testing to ensure that new changes do not impact existing functionality.

SDLC stands for Software Development Life Cycle, which is a process followed by software development teams to design, develop, test, and deploy high-quality software.

• SDLC is a structured approach to software development.

• It consists of several phases such as planning, analysis, design, implementation, testing, and maintenance.

• Each phase has its own set of activities and deliverables.

• The goal of SDLC is to produce high-quality software that meets customer requirements and is de...read more

Java is a programming language that supports object-oriented programming (OOP) concepts.

• Java is a high-level programming language known for its platform independence.

• OOP concepts in Java include classes, objects, inheritance, polymorphism, and encapsulation.

• Classes are blueprints for objects, which are instances of classes.

• Inheritance allows a class to inherit properties and behaviors from another class.

• Polymorphism allows objects to be treated as instances of their parent cl...read more

SDLC stands for Software Development Life Cycle, a process used to design, develop, and test software.

• SDLC involves phases like planning, analysis, design, implementation, testing, and maintenance.

• Example: In the planning phase, project requirements are gathered and feasibility is assessed.

• Example: In the testing phase, software is tested for bugs and errors.

• Each phase has specific deliverables and goals to be achieved before moving to the next phase.

C++ and Java are both popular programming languages, but they have key differences in syntax, memory management, and platform compatibility.

• C++ is a statically typed language, while Java is a dynamically typed language.

• C++ allows for manual memory management with pointers, while Java has automatic garbage collection.

• C++ is platform-dependent, while Java is platform-independent due to its bytecode compilation.

• C++ supports multiple inheritance, while Java only supports single i...read more
