In software development, there is an old saying “A code that cannot be tested is flawed”. Testing plays a very crucial role in software development, life cycle. This is one of the practice that is commonly used to produce a high quality software product. Testing itself is a separate phase in SDLC (software evelopment life cycle), but it is not isolated from development process i.e. coding and testing are inseparable components of software development, and are very closely connected with each other. The best results will be obtained when programmers and testers work head to head with each other.
Several popular testing approaches are followed for effectively design and producing a software solution. One of them is Extreme Programming. In Extreme Programming, the testing code is written and developed before writing the real code.
These approach help us tackling the problems easily and reduce the chances of errors in the system. One of the similar approach is followed in agile development, here we write high level test cases first before even starting the coding. This is a very effective approach no matter what development methodology is used by the developers. Testing help experts and business analysts to clarify the requirement for a particular feature or piece of functionality (module).
When the coder start developing the module, the tester start creating the scenarios for the desired result as expected by the client. They design test cases to test all parameters like behavior, functionality, logic, performance etc.Tester use various techniques to execute these cases. Commonly they manually execute all the steps and verify the modules. Sometimes they use automation tools and techniques to execute the test cases automatically.
Automation testing is very popular nowadays because it’s more efficient and saves valuable time for the testers. With automation testing we can explore different levels in product satisfaction and solution development.We use certain tools for automation testing and write scripts for execution. Throughout the software development, process the testers work parallel with the developers to write test cases, write code, more test cases, and more code iteratively and so on until the desired requirements are met and the product or software is released.

The use of the term "technology" has changed significantly over the last 200 years. Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems
