Fundamentals of functional testing

Application functional testing is the most extensively acknowledged testing practice in all major software development organizations. Billions of dollars have already been spent on automated tools to support the automatic testing practice but organizations are still struggling to get the fine software quality. Regardless of this huge investment in automation more than seventy percent of software testing is still done manually. Determining what has been tested and what is left is the leading challenge in most of the organizations, and the time commitment necessary for quality assurance functional testing is one of the biggest concerns for meeting application delivery.

Use of automated tools alone can’t guarantee that the functional testing is precise and absolute. To achieve this target, the tools must be supported by a crystal-clear practice for its use and must be incorporated into an organization's software development process also. An efficient and constantly-applied functional testing practice is the only way to make sure that software satisfies estimated specification, functionality and consistency objectives.

Almost every software development organization, where an efficient functional testing practice is followed, has a quick and successful way to find out whether each functional constraint is actually implemented in the coding. With the help of functional testing, the testing team converts functional requirements into executable test cases that verify if the    code satisfies all the requirements properly at any given moment.

Develop and implement good test plan to build a collection of executable tests that verify the functionality requirements and tests can then be executed to guarantee that code alteration do not inadvertently change previously established functionality. A successful functional testing practice includes the definition of guiding principles for using functional testing technology efficiently, and then the implementation and integration of that strategy into your software development lifecycle to make certain that your team applies this course of action continually and frequently.
