To find out what features make these two independent testing services different, let’s focus on types of operational app testing services and define each type point by point:
- Alpha testing is carried out within a development center with a possible partial involvement of the end users. It may be a form of internal acceptance testing. In some sources, it is told that this type of testing should be carried out without the involvement of the development team while other sources do not have such strict demands. Briefly about the idea of alpha testing: the product can be periodically demonstrated to external users though it is still quite “raw”, that is why basic app testing services are carried out by the development organization.
- Beta testing is performed outside the development organization with the active involvement of the end users/customers. It may be a form of external acceptance testing. Briefly about the idea of beta testing: the product can be already shown to external users, it is quite stable, but some errors can still occur that is why the feedback from real users is needed to detect these errors. It is the scheme of work of most beta testing companies.
Gamma testing is a final stage of testing before the release of the product. It is aimed to detect the errors and to make further their corrections. Beta testing helps with that. As a rule, gamma testing is also carried out with the maximum involvement of users/customers. Gamma testing may be a form of external acceptance testing. Briefly about the idea of this type of testing: the product is almost ready, and now the feedback from real users is used to eliminate the bugs.
