Acceptance testing is formal testing conducted by clients or end users to determine if a system meets business needs and requirements. There are two main types: user acceptance testing (UAT) ensures the system satisfies contractual criteria before being approved, while business acceptance testing (BAT) is conducted by the supplier's development team to ensure the system will pass acceptance. Acceptance testing has the objectives of confirming the system criteria and identifying any discrepancies.

Acceptance testing

2. Acceptance testing is a formal testing
conducted to determine whether a system
satisfies the business criteria.
This testing is done based on business
requirements and needs.
It is performed by Client or end user with or
without the assistance of testers.

3. Types of Acceptance Testing:
Two categories of acceptance testing are:
1) User Acceptance Testing (UAT)
2) Business Acceptance Testing ( BAT)
User Acceptance testing:
To ensure that the system satisfies the contractual
acceptance criteria before being signed off as
meeting user needs, User acceptance testing is
done.

4. Business Acceptance testing:
To ensure that the system will pass the acceptance
test, the development organization of the supplier
will conduct the
Business acceptance testing.
 Objectives of Acceptance Testing.
1) Confirms that the system meets the criteria.
2) If there are any discrepancies, that can be
identified.

5. Traditional BA (Waterfall) Agile BA
Requirements are documented in Use
Cases,Business Requirements, Functional
requirements, UI Specifications, Business Rules.
Requirements are documented in Epics, User
Stories and optionally Business (or Essential) Use
cases.
Focuses on completeness of requirement and
spends time in ensuring the requirement is
unambiguous and has all the details.
Focuses on understanding the problem and being
the domain expert so that s/he can answer
questions from the development team swiftly and
decisively.
Focuses on getting a ‘sign off’ on the requirements.
Focuses on ensuring the requirements meet the
currentbusiness needs, even if it requires
updating them.
Often there is a wall between the BA/Business and
the Development team.
Agile BA (Often called as Product Owner) is part of
the team.
Tends to dictate solutions.
Has to remain in the problem domain, leaving the
development team ‘space’ to explore different
solutions.
Long turnaround. Quick turnaround.
Focus on what the requirements document said. In
other words, output (Artifact) is a well written
thorough requirements document.
Focus on the functionality of the developed
software. In other words, output (Artifact) is the
software that meets thebusiness needs.
Execution of Acceptance Testing:
Acceptance test cases are divided into sub groups
1) Basic test cases
2) Test cases that are complex to execute
3) These test cases are executed in two phases
4) Basic test cases from the basic test group are
executed in first phase.
5) If the test results are satisfactory, then
second phase is executed where the complex
test cases are taken up.

6. UAT Activities
Some steps when doing UAT
1) User acceptance Test planning
2) Designing UAT Test cases
3) Approve acceptance test plan
4) Executing Test cases
5) Documentation of the defects found
during UAT
6) Resolving the defects fixing.
