Description: An executable specification is a document that describes the expected behavior of a software system in a way that can be executed as part of the testing process. This type of specification is used in behavior-driven development (BDD), where the goal is to align software development with business expectations and end-user needs. Executable specifications are written in a clear and understandable language, allowing both developers and non-developers to comprehend them. This facilitates collaboration among multidisciplinary teams and ensures that all stakeholders share a common vision of the product. Additionally, since they are executable, these specifications can be used to validate that the software meets the established requirements, enabling the detection of errors and deviations at early stages of development. Automation testing tools, such as Cucumber or SpecFlow, are commonly used to implement executable specifications, allowing tests to be conducted continuously throughout the development lifecycle. In summary, executable specifications are a key tool in agile development, promoting effective communication and software quality.
