Lettuce
Lettuce is a behavior-driven development (BDD) tool for Python that allows developers to write automated tests in a natural language style using Gherkin syntax. It enables the creation of executable specifications that describe application behavior in plain English, making tests more readable and accessible to non-technical stakeholders. It integrates with Python's testing ecosystem to run scenarios defined in feature files.
Developers should use Lettuce when working on Python projects that require clear, human-readable test specifications, especially in agile or collaborative environments where business analysts and QA teams are involved. It is ideal for implementing BDD practices to ensure software meets business requirements, such as in web development with frameworks like Django or Flask, and for improving test documentation and communication across teams.
