Software Testing - Basics
Introduction Software Testing plays a very crucial role in the process of software development. Software testing is that phase of software development where the quality analyst engineers determine the quality of a software product by conducting manual and automated testing on it. If they find any error or malfunction in the product, then they send it for the corrections. After corrections, again testing is done to make sure that the previous set of errors no more exists.
Software testing is the process of making the software flawless. Without software testing, the process of the software development is considered incomplete. Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation.
Types in Testing Black
box testing- examines the functionality of an application without peering into its internal structures.
White
box testing- This testing is based on knowledge of the internal logic of an application’s code. Also known as Glass box Testing

Unit testing- Unit testing is a software development process in which the smallest testable parts of an application, called units, are individually and independently scrutinized for proper operation.
Incremental integration testingIncremental integration testing encompass the basic concepts of integration testing. It is continuous or repetitive testing of a software application as new and fresh functionality is advised. You may need different aspects of software application’s functionality that are independent to work separately before you complete all parts of program. Programmers, software engineers, or test engineers may carry out this type of testing. 
Functional testing-Functional testing verifies that each function of the software application operates in conformance with the requirement specification.
This testing mainly involves black box testing and it is not concerned about the source code of the application.
System testing- System Testing (ST) is a black box testing technique performed to evaluate the complete system the system's compliance against specified requirements. There few more types in software testing.
A trustworthy software testing company understands client's requirements and works accordingly. Such companies strictly follow all the bug testing processes and quality systems related to software validation. The project manager of the company plans and schedules the projects with utmost care and diligence. Every project requires different software testing depending upon its size, scope and usability. The software testing companies make use of the latest techniques and take all measures during software testing to impart optimum quality to the software.
A good software tester must have good analytical and strong technical skills along with good verbal and written communication skills. Technical skills include high level of proficiency in tools like MS Office , OpenOffice etc. Testing tools like QTP ,Loadrunner , etc. and of course deep understand of the application under test. All these skills can be acquired through relevant training and practice offered by good software testing training institutes which offer quality software testing course.
