Static testing is the process of evaluating the sanity of the code, algorithm and documents without any execution on computer. It is the only available method to find defects in the early stages of the Software Development Life Cycle. It is completed before the implementation of code.

Static testing can be done through:
1. Walkthrough
2. Inspection
3. Informal Review
4. Technical Review

Walkthrough involves presenting a technical document in a meeting. This is a useful technique to ensure that everyone understands the product. The author of the work product calls for a meeting and presents the product to reviewers, inspection team, engineering leads, managers and other key stakeholders of the product.

Inspection is a well-known software engineering tool to improve the entire development process. In this phase we gather data on the weaknesses in the process and number of hours in correcting them using statistical process control techniques. It is a pre-requisite to reviews. It may be wasteful to do reviews unless the document has successfully exited inspection.

Reviews focus on getting consensus or buy-in to a particular document. Review is the most effective and universal test method. It could be a peer group discussion activity. In this phase the developers can find errors like unreachable code or references to variable that are not initialized. Testers can make sure that the documents (screen design, FSD) are built to standards. Incremental reviews throughout the product construction are essential and profitable method of managing quality.

Review Procedure:
1. What are we testing?

a. Requirements review
b. Feasibility review
c. Review screen layout against standards
d. Analyze program’s control and data flow
e. Existential check of the features expected as a part of the product
f. Review the screen designs, FSD

2. What are the criteria for success?

a. Check for correct and required output
b. Test environment

3. Who will do the work ? (roles & responsibilities)
