Testing Strategy
During testing the software engineering produces a series of test cases that are used to "rip apart" the software they have produced. Testing is a group of activities that can be planned in advance and performed systematically. For this reason a set of stages that we can place particular tests case design techniques and test approaches should be developed for the software engineering procedure. A number of testing strategies have been identified, which provide a template for testing and all have the following features:

Testing starts at the modular level and works outward towards the integration of the complete system.

Diverse testing techniques are appropriate at diverse points in time.

Testing is performed by the developer of the software and an independent test group.

Testing and debugging ate diverse activities, but debugging must be included in any testing strategy.

A strategy for testing includes low-level tests that are required to verify that a small source code segment has been implemented correctly as well as high-level tests that that validate major system functions based on customer requirements.

Importance of Testing
Software testing is a critical component of the Software Development cycle. The importance of Software testing and its impact on Software cannot be underestimated. It's testing procedures are critical to the success of the testing phase.

Software remains in a perpetual state of change which is why software testing, whether manual or automated, is so vital to a software product's success. The ultimate concern of all those involved in the production of the code that implements a software system must be that the software produced is of high quality.
