**Code coverage for what matters — your changes.**

Delta Coverage is a Gradle plugin that computes code coverage of new/modified code based on a git diff. Focus on testing what you've changed, not the entire codebase.

📖 **[Full Documentation](https://gw-kit.github.io/delta-coverage-plugin)**



## Quick Start

**1. Apply the plugin** (root project)

```kotlin

plugins {

    id("io.github.gw-kit.delta-coverage") version "3.6.0"

}

```

**2. Configure diff source**

```kotlin

configure {

    diffSource.git.compareWith.set("refs/remotes/origin/main")

}

```

**3. Run**

```bash

./gradlew test deltaCoverage

```

Reports are generated in `build/reports/coverage-reports/`.

## Compatibility

| Delta Coverage | Gradle | Min JVM |

|----------------|--------|---------|

| 3.x | 7.6.4+ | 17 |

| 2.5.x | 6.7.1 - 8.10.2 | 11 |
