The document outlines user acceptance testing (UAT) and differentiates it from functional testing, highlighting its importance in ensuring software meets user requirements. It describes five types of UAT: alpha testing, beta testing, contract acceptance testing, regulation acceptance testing, and operational acceptance testing. Additionally, the document emphasizes the benefits of UAT, such as capturing user requirements, identifying problems, and confirming that the software is ready for customer use.

7. Getting started with UAT

8. Getting started with UAT
If you’re just getting started with User Acceptance Testing,
we’ve prepared a UAT checklist you can download.

9. When & Why UAT?
Running those acceptance tests also ensures that no
requirement change has happened in the meantime and
that everything is as it should be to satisfy the customer.

10. When & Why UAT?
Acceptance tests are useful, because:
they capture user requirements in a directly verifiable way,
they identify problems which unit or integration tests
might have missed,
and they provide an overview on how “done” the system is.

11. When & Why UAT?

12. How is UAT different from functional testing?
User Acceptance Tests consist of a set of test steps,
which verify if specific requirements are working for the
user. If the customer and the supplier agree on the product,
the software development is done. Legally. And practically.
Functional testing, on the other hand, tests specific
requirements and specifications of the software. It lacks the user
component. A functional test could conclude that the software
meets its specifications. However, it doesn’t verify if it actually
works for the user. The functional dimension is only one of many.

13. Types of UAT
Now that we’ve clearly separated functional testing from
User Acceptance Testing, we can look at the various types
of User Acceptance Testing.

14. Types of UAT
Alpha Testing:
Alpha Testing takes place in the development environment and is usually done
by internal staff – long before the product is even released to external testers
or customers. Alpha Testing can also be done by potential user groups, but the
important thing here is that it takes place in the development environment.
Beta Testing:
Beta Testing, also known as “field testing”, takes place in the customer’s
environment and involves some extensive testing by a group of customers
who use the system in their environment. These beta testers then provide
feedback, which in turn leads to improvements of the product.

15. Types of UAT
Contract Acceptance Testing:
Contract Acceptance Testing means that a developed
software is tested against certain criteria and specifications
which are predefined and agreed upon in a contract.
The relevant criteria and specifications for acceptance must
be defined when the contract itself is defined and agreed
upon.

16. Types of UAT
Regulation Acceptance Testing:
Regulation Acceptance Testing, also known as
Compliance Acceptance Testing, examines whether
the software complies with the regulations. This
includes governmental and legal regulations.

17. Types of UAT
Operational Acceptance Testing
Also known as Operational Readiness Testing or Production
Acceptance Testing, these test cases ensure there are
workflows in place to allow the software or system to be
used.
This should include workflows for backup plans, user
training, and various maintenance processes and security
checks.

18. Types of UAT
Black Box Testing
It’s, basically, a method of software testing which
analyzes certain functionalities without letting the
tester see the internal code structure of the
software.

19. OVER TO
YOU
Of course, there are many more types of and
frameworks for User Acceptance Testing.
I hope that, by providing you with our basic
overview of 5 types of User Acceptance Testing,
we shed some light into the darkness of UAT.
