UAT and usability testing appear to have many similarities in terms of goals and output, and often purpose.
I’ve read how some comparisons being made about User Acceptance Testing and Usability Testing before.
Are they essentially the same thing but just carried out at different stages of the testing process with different terminology?
Some similarities are using end users rather than users involved in the project, testing the steps of a given task to identify errors but with the results used for different reasons. (end users Vs Business requirements)
Are they then really that different from each other? Or is there a lot of overlap between the two types?
