Types of Acceptance Testing
Typical types of acceptance testing include the following
- User acceptance testing
- This may include factory acceptance testing, i.e. the testing done by factory users before the product or system is moved to its destination site, after which site acceptance testing may be performed by the users at the site.
- Operational Acceptance Testing (OAT)
- Also known as operational readiness testing, this refers to the checking done to a system to ensure that processes and procedures are in place to allow the system to be used and maintained. This may include checks done to back-up facilities, procedures for disaster recovery, training for end users, maintenance procedures, and security procedures.
- Contract and regulation acceptance testing
- In contract acceptance testing, a system is tested against acceptance criteria as documented in a contract, before the system is accepted. In regulation acceptance testing, a system is tested to ensure it meets governmental, legal and safety standards.
- Alpha and beta testing
- Alpha testing takes place at developers' sites, and involves testing of the operational system by internal staff, before it is released to external customers. Beta testing takes place at customers' sites, and involves testing by a group of customers who use the system at their own locations and provide feedback, before the system is released to other customers. The latter is often called “field testing”.
