Executable BDD specifications are expected behaviors written in a domain-specific language before coding. They use scannable approval tests to drive implementation, ensuring human-readable fixtures remain synchronized with the actual software behavior throughout development.

To write approval tests for a new feature, define its expected outcomes by creating an approval file in the specified domain language. You then drive implementation by making the code pass these human-readable, scannable specifications.

Use approval tests when human validation of expected outcomes is critical and requires a clear, glanceable format. They are ideal for scenarios needing scannable fixtures, like structured text or ASCII art, to verify complex behavior easily.

Yes, this approach supports creating scannable fixtures using human-readable formats like ASCII art or structured text. This design ensures test cases are easily understandable and allow quick human validation of expected outcomes.

The best way to maintain executable specifications is to write expected behavior in a domain language before coding. Driving implementation through approval files ensures tests remain current, correct, and easily understandable over time.

No specific testing frameworks or dependencies are required to start writing executable BDD specs. You can begin by defining expected behavior for a new feature through a simple approval file in your domain language.
