Regression testing is a type of software testing that intends to ensure that changes to the software have not adversely affected it.Regression testing is only done when there is any modification or changes become mandatory in an existing project        The regression testing strategy used to share the approach to perform testing that includes testing technique needs to use, completion criteria usage, writing test scripts, and the automation tool that is being used for covering the test cases.Regression testing becomes very important to test whether existing functionality is impacted.
Exploratory testing is a technique that is not traditional but is a very useful and efficient way to perform software testing.Exploratory testing is a hands-on approach in which testers are involved in minimum planning and maximum test execution.It is scientifically proved that exploratory testing gives more efficiency as compared to scripted testing.It is used to find bugs that have been missed during scripted testing.Exploratory testing is the process of learning the product, designing test cases, executing test cases and interpreting the test results at the same time.Hence, it represents the perfect counterpart.
  Functional testing is a software testing type, where each part of the software is tested against user specifications and functional requirements.Functional tests are related to integration tests, however, they signify to the tests that check the entire application's functionality with all the code running together, nearly a super integration test.Functional testing ensures that the requirements or specifications are properly satisfied by the application.This type of testing is particularly concerned with the result of processing.Functional testing is performed according to the business requirements.This form of testing is performed according to customer expectations based on the required app performance.To know more visit: https://pradtutorials.com/functional-testing/ 
ETL testing is one of the software testings.Software testing is defined as the testing which is conducted to make sure that the actual results match the expected results without any defects.ETL testing is a type of testing performed to ensure that the data migrated from source to destination database is accurate and it has followed the valid transformation rules.ETL testing is a multi-level, data-centric process.It uses complex SQL queries to access, extract, transform and load millions of records contained in various source systems into a target data warehouse.To get more information visit: https://pradtutorials.com/etl-testing/
 API testing is a one of software testing types.API testing involves testing application programming interfaces directly and as part of integration testing to determine if they meet expectations for functionality, reliability, performance, and security.API testing is one of the most demanding segments of the software and quantitative analysis testing.Before we discuss this testing type, we will first understand what exactly the API is.To get more information visit: https://pradtutorials.com/api-testing/
 Grey box testing is a software testing technique to test a software product or application with partial knowledge of internal structure of the application.The aim of this testing is to search for the defects if any due to improper structure or improper usage of applications.Grey-box testing is the best technique for domain or functional testing Grey Box Testing Strategy It is not necessary in Grey box testing that source code is required by the tester to design test cases.Visit: https://pradtutorials.com/grey-box-testing/

 Artificial intelligence and machine learning are the a part of computing that are correlated with one another.These two technologies are the foremost trending technologies which are used for creating intelligent systems.Even in the tech field in general, everyone talks about artificial intelligence vs machine learning and many are eager to learn about them.Visit for more details: https://pradtutorials.com/artificial-intelligence-vs-machine-learning/
Slicing in Python is a feature that enables accessing parts of sequences like strings, tuples, and lists.Python provides two overloaded slice functions.The first function takes a single argument while the second function takes three arguments and returns a slice object.Click here to example program: https://pradtutorials.com/slicing-in-python/
           In this tutorial we will see how to reverse a string using recursion.Python doesn't have the inbuilt reverse() function.However, there are various ways to reverse any string in Python.To reverse a string, we can use an array index, or there are 6 ways to reverse a string in python.Click here for example program: https://pradtutorials.com/reverse-a-string-in-python/
   In Python Fibonacci series can be explained as a sequence of numbers where the numbers can be formed by adding the previous two numbers.Fibonacci Series In Pythonusing recursion Create a recursive function which receives an integer as an argument.Fibonacci Series in Python using For Loop.In this tutorial, we will write a Python program to print Fibonacci series, using for loop.For example program cick here:  https://pradtutorials.com/fibonacci-series-in-python/ 
  A python Queue is a data structure where the first element to be inserted is also the first element popped.Python queue is an important concept in data structure.We can create a queue by importing the Queue class.When you create a queue in python you can think it as of Lists that can grow and Shrink.A Python queue is a Linear Data Structure that stores data values in sequential order.It is similar to the ticket queue outside a cinema hall, where the first person entering the queue is the first person who gets the ticket.
 In Python or any other Programming Language to calculate the square root of a number, we have different methods.sqrt () is the predefined method used to find python-square-root.Python provides built-in methods to calculate square roots.Now that we have a basic idea on what is a square root of a number and how to represent it, let's move ahead and check how we can get the square root of a number in Python.example program for squre root: https://pradtutorials.com/python-square-root/.
 Python  Simple and easy to Learn .A few of the other notable features of Python are the library functions & modules are reliable in nature, facilitates the developers with its interactive mode.Python works on almost all types of platforms such as Windows, Mac, Linux, Raspberry Pi, etc.Python supports object oriented features.Compared with other programming languages, Python's class mechanism adds classes with a minimum of new syntax and semantics.To learn more about python: https://pradtutorials.com/features-of-python/
Python programming language has various data types including strings.The Split Python function is a commonly-used string manipulation tool.It separates string based on the separator delimiter.This method will return one or more new strings.All substrings are returned in the list data type.To split a String in Python using delimiter, you can use split () method of the String Class on this string.In this tutorial, we shall learn how to split a string in Python, with well detailed Python example programs.Example program here: https://pradtutorials.com/python-split/
