TL;DR
I just released jacoco-badge-generator 2.10.0, which can be run as a GitHub Action or as a command-line utility as part of CI/CD workflows for Java projects, as well as for projects in other JVM languages such as Kotlin, to parse JaCoCo test coverage reports, generate instructions coverage and branches coverage badges for project READMEs, serve as pull-request checks (e.g., validate minimum coverage thresholds), among other functionality.
Changelog 2.10.0 - 2023-09-04
Added
- Option to suppress workflow job summary in GitHub Actions Mode.
Dependencies
- Bump cicirello/pyaction from 4.19.0 to 4.22.0.

The jacoco-badge-generator can be used in one of two ways: as a GitHub Action or as a command-line utility (e.g., such as part of a local build script). The jacoco-badge-generator parses a jacoco.csv from a JaCoCo coverage report, computes coverage percentages from JaCoCo's Instructions and Branches counters, and generates badges for one or both of these (user configurable) to provide an easy to read visual summary of the code coverage of your test cases. The default behavior directly generates the badges internally with no external calls, but the action also provides an option to instead generate Shields JSON endpoints. It supports both the basic case of a single jacoco.csv, as well as multi-module projects in which case the action can produce coverage badges from the combination of…

The jacoco-badge-generator GitHub Action parses a jacoco.csv from a JaCoCo coverage report, computes C0 and C1 coverage percentages from JaCoCo's Instructions and Branches counters, and generates badges for one or both of these (configurable with action inputs) to provide an easy to read visual summary of the code coverage of your test cases. The jacoco-badge-generator can also optionally be used as part of a pull-request check, failing workflows if coverage below a threshold or if it decreased.
