For running the OAT test cases, the tester normally has exclusive access to the system or environment. This means that a single tester would be executing the test cases at a single point of time. For OAT the exact Operational Readiness quality gates are defined: both entry and exit gates. The primary emphasis of OAT should be on the operational ...
UAT should be executed against test scenarios. [14] [15] Test scenarios usually differ from System or Functional test cases in that they represent a "player" or "user" journey. The broad nature of the test scenario ensures that the focus is on the journey and not on technical or system-specific details, staying away from "click-by-click" test ...
Acceptance test–driven development (ATDD) is a development methodology based on communication between the business customers, the developers, and the testers. [1] ATDD encompasses many of the same practices as specification by example (SBE), [2] [3] behavior-driven development (BDD), [4] example-driven development (EDD), [5] and support-driven development also called story test–driven ...
User Acceptance Test (UAT) Plans are developed during the Requirements Analysis phase. Test Plans are composed by business users. UAT is performed in a user environment that resembles the production environment, using realistic data. UAT verifies that the delivered system meets the user's requirement and the system is ready for use in real-time.
A test case usually contains a single step or a sequence of steps to test the correct behavior/functionality and features of an application. An expected result or expected outcome is usually given. Additional information that may be included: [7] Test case ID - A unique identifier for the test case. Description/summary - The test case objective.
Smoke tests are a subset of test cases that cover the most important functionality of a component or system, used to aid assessment of whether main functions of the software appear to work correctly. [ 1 ] [ 2 ] When used to determine if a computer program should be subjected to further, more fine-grained testing, a smoke test may be called a ...
For example, Finite State Machine-based modeling [2] [3] – where a system is modeled as a finite state machine and a program is used to generate test cases that exercise all states – can work well on a system that has a limited number of states but may become overly complex and unwieldy for a GUI (see also model-based testing).
Specification-based testing aims to test the functionality of software according to the applicable requirements. [2] This level of testing usually requires thorough test cases to be provided to the tester, who then can simply verify that for a given input, the output value (or behavior), either "is" or "is not" the same as the expected value specified in the test case.
