Covered

Covered uses modern Ruby features to generate comprehensive coverage, including support for templates which are compiled into Ruby.

• Incremental coverage - if you run your full test suite, and the run a subset, it will still report the correct coverage - so you can incrementally work on improving coverage.
• Integration with Sus, Git, RSpec and Minitest- no need to configure anything - out of the box support for these platforms.
• Supports coverage of views - templates compiled to Ruby code can be tracked for coverage reporting.

Motivation

Originally, Ruby coverage tools were unable to handle evaled code. This is because the coverage module built into Ruby doesn't expose the necessary hooks to capture it. Using the parser gem and trace points allows us to do our own source code analysis to compute executable lines, thus making it possible to compute coverage for "templates".

After this concept prooved useful, it was integrated directly into Ruby.

Usage

Please see the project documentation for more details.

• Getting Started - This guide explains how to get started with covered and integrate it with your test suite.

• Configuration - This guide will help you to configure covered for your project's specific requirements.

Releases

Please see the project releases for all releases.

v0.30.0

• Ignore files under integration/ when evaluating coverage.

v0.29.0

• Prefer ruby-coverage over coverage for improved coverage tracking.

v0.28.5

• Make coverage validation quiet when no reports are configured.

v0.28.4

• Ensure coverage validation loads explicit coverage databases without reloading the default persisted database.

v0.28.3

• Ignore nil coverage reports so validation can run without COVERAGE configured.

v0.28.2

• Ensure bake coverage validation loads persisted coverage using project configuration.

v0.28.0

• List files that have 100% coverage in PartialSummary output.

v0.27.0

• Drop development dependeny on trenni and add dependeny on xrb.

See Also

• simplecov – one of the original coverage implementations for Ruby, uses the built-in coverage library.
• sus - a test framework which uses covered to generate coverage reports.
