Smoke testing is a subset of regression testing, while sanity testing is a subset of acceptance testing.

• Smoke testing is done to check if the critical functionalities of the software are working fine after a build.

• Sanity testing is done to check if the new changes or fixes in the software are working fine and not breaking the existing functionalities.

• Smoke testing is done before the actual testing process begins, while sanity testing is done after the completion of the testin...read more

STLC stands for Software Testing Life Cycle. Agile principles include iterative development, customer collaboration, and continuous improvement.

• STLC is a process followed by software testers to ensure quality of the software product.

• It includes phases like requirement analysis, test planning, test design, test execution, and test closure.

• Agile principles prioritize customer satisfaction, working software, and responding to change.

• Iterative development involves delivering smal...read more

HTTP methods differ in manual and automation testing in terms of execution speed, accuracy, and coverage.

• Manual testing involves human intervention and is time-consuming.

• Automation testing is faster and more accurate.

• Automation testing can cover a larger number of test cases.

• Manual testing is better for exploratory testing and usability testing.

• Automation testing is better for regression testing and load testing.

• Both manual and automation testing are important for comprehensi...read more

Java OOPS concepts are the foundation of Java programming, focusing on objects, classes, inheritance, polymorphism, encapsulation, and abstraction.

• Objects: Instances of classes that encapsulate data and behavior

• Classes: Blueprint for creating objects, defining attributes and methods

• Inheritance: Allows a class to inherit attributes and methods from another class

• Polymorphism: Ability to present the same interface for different data types

• Encapsulation: Bundling data and methods ...read more

SQL join types are used to combine rows from two or more tables based on a related column between them.

• Inner Join: Returns rows when there is at least one match in both tables.

• Left Join (or Left Outer Join): Returns all rows from the left table and the matched rows from the right table.

• Right Join (or Right Outer Join): Returns all rows from the right table and the matched rows from the left table.

• Full Join (or Full Outer Join): Returns rows when there is a match in one of the...read more

ArrayList is a dynamic array that can grow or shrink in size as needed.

• ArrayList internally uses an array to store the elements.

• When the array is full, a new array is created with a larger size and the elements are copied to the new array.

• ArrayList allows null values and duplicates.

• It provides constant time access to elements using index.

• It provides linear time access to elements using contains() and indexOf() methods.

Software testing is the process of evaluating a software application or system to find defects and ensure it meets the specified requirements.

• Software testing involves executing a program or application with the intent of finding errors.

• It ensures that the software meets the functional and non-functional requirements.

• It helps in identifying defects early in the development cycle, reducing the cost of fixing them later.

• Types of software testing include unit testing, integratio...read more

Synchronization is the process of controlling access to shared resources by multiple threads.

• Synchronization ensures that only one thread can access a shared resource at a time.

• It is achieved using synchronized keyword or locks.

• Synchronization can cause performance issues if not used properly.

• Example: Multiple threads accessing a shared variable without synchronization can lead to race conditions and inconsistent results.

Static variables are shared among all instances of a class, while non-static variables are unique to each instance.

• Static variables are declared using the 'static' keyword, while non-static variables are not.

• Static variables are initialized only once, at the start of the program, while non-static variables are initialized each time an instance is created.

• Static variables can be accessed using the class name, while non-static variables are accessed using an instance of the cla...read more

Blue screen errors can occur due to hardware or software issues, such as faulty drivers or hardware failures.

• Blue screen errors are often caused by incompatible or outdated device drivers.

• Hardware failures, such as faulty RAM or hard drive, can also trigger blue screen errors.

• Software conflicts or corruption can lead to blue screen errors.

• Overheating of the computer components can cause blue screen errors.

• Viruses or malware infections can result in blue screen errors.

• Incorrec...read more
