2014 · Ecto modularization and test coverage

This period focused on refactoring the Ecto codebase into specialized, modular components for adapters, query building, and repository operations. Comprehensive test suites were added to validate the new architecture and ensure correct behavior across query planning, execution, and task management.

2015–2023 · comprehensive test coverage and example application

This period focused on establishing robust test coverage for Ecto's core features, including associations, changesets, and repository operations. The team also introduced a new 'Friends' example application to serve as a reference implementation for users. Additionally, internal refactoring improved schema loading logic and added documentation cheatsheets for common Ecto patterns.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 62c25bd9c1 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
