SOFTWARE TESTING METRICS

In general testers must rely on metrics collected in analysis, design and coding stages of the development in order to design, develop and conduct the tests necessary. These generally serve as indicators of overall testing effort needed. High-level design metrics can also help predict the complexities associated with integration testing and the need for specialized testing software (e.g. stubs and drivers). Cyclomatic complexity may yield modules that will require extensive testing as those with high cyclomatic complexity are more likely to be error prone.
Metrics collected from testing, on the other hand, usually comprise of the number and type of errors, failures, bugs and defects found. These can then serve as measures used to calculate further testing effort required. They can also be used as a management tool to determine the extensity of the project's success or failure and the correctness of the design. In any case these should be collected, examined and stored for future needs.
