Okyline is an Executable Data Design (EDD) platform focused on executable validation contracts and operational data quality control.
Rather than managing separate specifications, validation code, tests, and monitoring dashboards, Okyline centralizes validation and quality supervision around a single readable executable contract acting as the operational reference for enterprise data flows.
The same contract powers deterministic validation, advanced business invariant checks, multi-format execution, data quality gates, and historical quality analytics across APIs, events, files, LLM structured outputs, and distributed operational systems.
Contracts are designed directly from annotated sample data, making validation rules immediately understandable for developers, architects, QA teams, and business analysts.
The Community Edition includes the public specification, a free Java runtime engine, a Claude AI assistant for contract generation, and an online studio supporting executable JSON validation contracts and JSON Schema transpilation.
The Enterprise Edition adds native validation for JSONL, XML, CSV, FIXED, and EDI flows together with operational quality dashboards and data quality gates, without requiring databases or centralized infrastructure.erprise Edition supports direct validation of JSON, JSONL, XML, CSV, FIXED, and EDI flows with operational quality dashboards and analytics, without databases.

JUnit
JUnit 5 represents the evolution of the JUnit framework, aiming to establish a modern foundation for testing on the JVM that caters to developers. It emphasizes compatibility with Java 8 and later versions while also supporting various testing methodologies. We encourage our users to back our efforts, as your contributions would allow us to maintain momentum. Our commitment to JUnit will persist, regardless of the level of financial support we receive, but additional backing would enable us to concentrate our efforts more effectively rather than just working on it during our free time. For instance, we aspire to hold regular meetings and collaborate closely for several days, which would facilitate quicker progress through in-person design and coding sessions. By contributing, you can help turn this vision into a reality while enhancing the overall development process!

HUnit
HUnit serves as a unit testing framework tailored for Haskell, drawing inspiration from the widely used JUnit framework within the Java ecosystem. Users who are already acquainted with Haskell will find HUnit straightforward to adopt, even if they lack prior experience with JUnit. A development approach that prioritizes testing proves to be most efficient when the process of creating, modifying, and running tests is seamless. JUnit was instrumental in introducing test-first development practices in Java, and HUnit functions as its counterpart for Haskell, a language known for its purely functional paradigm. Like JUnit, HUnit allows developers to effortlessly craft tests, assign names, organize them into suites, and run them while the framework automatically validates the outcomes. The test specification in HUnit boasts greater conciseness and flexibility compared to JUnit, which is a direct benefit of Haskell's design. Although HUnit currently supports a text-based test controller, it is structured to facilitate straightforward extensions in the future. To maximize efficiency, it is recommended to run the tests collectively as a suite.
