What is ESpec?

A design specification is the artifact intermediate between implemented code and the customer requirements. ESpec is a Software Quality Workbench that allows customer requirements and design specifications to be tested and tested early in the design cycle leading to early detection of requirement and specification errors. The core idea behind early testable requirements is that the problem is described before we search for a solution that can be tested against the problem description. We also want the problem description to drive the design.

ESpec allows for the description of testable requirements via Fit tables as well as testable design specifications via contracts written in Eiffel using mathematical models following the single model principle. The tool can mechanically check the requirements and specifications.

ESpec is a combination of three main components:

  • ES-Fit: A Requirements Testing tool for capturing and testing customer requirements in the form of HTML tables used for Validation.

  • ES-Test: A Unit Testing framework for testing specifications. A combination of Unit tests and Contracts are used for lightweight Verification.

  • ES-Verify: A translator from Eiffel to Perfect language used for full Verification.

We focus on Unit Tests and Contracts as testable specifications and Fit Tables as testable requirements.
