- Identify the production environmentConsider the many scenarios you would wish to testSecurity, hardware, software, and network capabilities are all tested.
- Keep end-users in mind at all timesCustomer and site visitor satisfaction is critical to attaining a business performance testThis influences their propensity to return to a site or use an application again.
