1. Identify the needs, not to frequent changes (frequent changes, the code heavy workload, maintenance costs and the labor costs)
2. There are many times higher than the return of verification (high reusability of code without rewriting, in favor of regression testing)
3. The system is stable, stable interface
4. The product cycle is long (from a technical setting, to automate the code architecture, to the code development process itself is a cycle)
The project schedule is not very urgent
6. testers have the ability to write automated test scripts (usually the team development)
7. relatively standardized software development
