  • Other testing types

  • User Acceptance Testing


Unit testing

Unit testing

  • Testing a component of a system (e.g. a subprogram or hardware part) in isolation to see that it does what it’s supposed to do.


Integration testing

Integration Testing

  • Joining the component (software or hardware) to see that it behaves properly when joined to related components.

  • E.g. does a subprogram accept parameters or return values correctly to/from another subprogram?

  • Is a piece of hardware pin-compatible with the device it plugs into?


System testing

System Testing

  • Finding out whether the entire system with all of its components is working as it should.


User acceptance testing uat

User Acceptance Testing (UAT)

  • Formal testing of whether the intended user of the system or product is happy the way it carries out its functional and non-functional requirements, as specified in the SRS.

UAT

  • The project schedule may say all tasks are done…

  • The programmers may have cleared all known bugs…

  • So why wont the client settle their account and let you get on with your next project?

  • They want a demonstration that you have delivered on everything you promised.

  • That’s why you do User Acceptance Testing.


Before uat

Before UAT

  • Informal testing (testing as you go during development is finished.

  • Integration testing is finished.

  • The testing environment has been set up and test methodology agreed on.

  • Test data has been agreed on.

  • Criteria for success have been agreed on.


During uat

During UAT

  • Actual end-users are often used for UAT rather than managers

  • Skilled users can tell if a product has problems that a mere observer could never notice

  • In fact, modern developers seek end user input during design and development to avoid nasty surprises during UAT


What is the purpose of uat

What is the purpose of UAT?

  • To demonstrate that the system is fit for real use by real people in the business.

  • Is different to system testing which provesthat the system behaves in the way that was described in the SRS.

  • A product could satisfy the SRS but be a never-ending pain for its users.


What uat sounds like

What UAT sounds like

Developer:  The product should respond briskly. I click here, and we get instant response.

User: OK.

Developer: The product should be easy to read. See the font size and colours we used? OK?

User: They’re fine.

Developer: Help needs to be contextual. See, I open this and press F1 – relevant help appears.

User: Yep. OK.

Developer: Next, we had to make it disaster resistant. I’ll just pull out the power cord and see how it avoids data loss…


After uat

After UAT

  • User signs off on the product, accepting that it is satisfactory. Then the developer can be paid.

  • Any known defects that will not interfere with a commercial released are identified, and fixes are scheduled.

  • If functionality is unacceptable, a timeline is established with the developer to fix the problems and resubmit the problem for UAT.
