3 3  Acceptance Tests provide an unambiguous completion criteria for stories, the **Definition of Done**. A story is done when its associated acceptance tests have passed, along with all other existing tests. Only then can the estimated points of a story be added to the charts at the end of an iteration.

5 5  * **Integration Of All Components**: Acceptance testing is the ultimate test of whether a feature works or not. To check this, the software must be deployed in production mode and then tested from the user's point of view; if there is a GUI, this is usually done by interacting with it. Common tools used to simulate such user interactions are Cypress and Selenium.
6 -* **Always Production Ready**: Acceptance testing ensures the stability of the software by proving that it works correctly if it passes the tests. This prevents developers from inadvertently breaking features by changing the code. Since running acceptance tests is expensive, it is common to schedule an automated run once a day at midnight. If bugs occur, they are addressed immediately the next day.
6 +* **Always Production Ready**: Acceptance testing ensures the stability of the software by proving that it works correctly if it passes the tests. This prevents developers from inadvertently breaking features by changing the code. Therefore, software functionality cannot evolve backwards. However, this does not prevent code from technically rotting under the surface, so code should still be kept clean, not just functional.
7 +* **Execution Frequency**: Since running acceptance tests is expensive, it is common to schedule an automated run once a day at midnight. If bugs occur, they are addressed immediately the next day.
7 7  * **Implementation Timing**: Stories should not wait for acceptance tests to be completed. Ideally, acceptance tests should be started to be written in the previous iteration, but no later than after the IPM, so that they are completed before the story they verify. Since it is not possible to know with certainty which stories will be implemented in the next iteration, testers can ask stakeholders which stories are likely to come next. If acceptance testing is consistently late, QA will need to hire more people. QA and developers should communicate and negotiate the test structure, perhaps even pair programming, instead of the "eat or die" tactic of writing tests without consulting the developer.
8 -* **Specification By Business**: The business should specify the requirements at a level of detail that is specific enough for the developers to know what to do, but still short and vague enough not to contain details. Acceptance tests are story specification.
9 +* **Level of Detail**: The business should specify the requirements at a level of detail that is specific enough for the developers to know what to do, but still short and vague enough not to contain details. Acceptance tests are story specification.
9 9  * **Requirement Automation**: Wherever practically feasible, requirements should be written as automated tests.
10 10  * **Acceptance Test Anatomy**: Acceptance tests consist of **technical test code** and can contain **business test code**. The business test code is written in English and in natural language and, when executed, they run the technical test code written in a programming language. Acceptance tests are the link between easy-to-understand business requirements and test automation.
