Benefits of Static Testing

Static testing provides many benefits, some of which are listed below:

1. Detecting Defects Early: When applied early in the software development lifecycle, static testing enables the early detection of defects. Using static testing, we can identify defects in requirements, design specifications reviews or in, backlog refinement, etc. Defects found early are often much cheaper to remove than defects found later in the lifecycle. A defect in the requirements specification may propagate itself to the design, the code, and even the test cases. Defects discovered after the software is deployed to production are very costly. 
2. Preventing Defects: Static testing prevents defects in design or coding by uncovering inconsistencies, ambiguities, contradictions, omissions, inaccuracies, and redundancies in requirements.
3. Easy to find Defects: Static Testing identifies defects that dynamic testing does not detect easily. Review can find omissions. E.g., finding a missing requirement that may have been unlikely to find during dynamic testing.
4. Increase Development Productivity: Static Testing increases development productivity due to quality and understandable documentation, improved design, and more maintainable code. 
5. Improve Team Communication: Static Testing improves communication between team members while participating in reviews.
6. Reduce Cost and Time: Static testing reduces development, testing, and overall organization cost. Defect found and fixed during static testing techniques is almost always much cheaper for the organization than dynamic testing. Especially considering the additional costs associated with updating other work products and performing confirmation and regression testing. It reduces the total cost of quality over the software’s lifetime due to fewer failures later in the lifecycle or after delivery into operation.
