DangerSwiftCoverage

Danger-Swift plugin to show the coverage of the modified/created files.

Getting Started

Install DangerSwiftCoverage

Swift Package Manager (More performant)

You can use a “full SPM” solution to install both danger-swift and DangerSwiftCoverage.

• Add to your Package.swift:

let package = Package(
    ...
    products: [
        ...
        .library(name: "DangerDeps", type: .dynamic, targets: ["DangerDependencies"]), // dev
        ...
    ],
    dependencies: [
        ...
        // Danger Plugins
        .package(url: "https://github.com/f-meloni/danger-swift-coverage", from: "0.1.0") // dev
        ...
    ],
    targets: [
        .target(name: "DangerDependencies", dependencies: ["Danger", "DangerSwiftCoverage"]), // dev
        ...
    ]
)

• Add the correct import to your Dangerfile.swift: ```swift import DangerSwiftCoverage

Coverage.xcodeBuildCoverage(.derivedDataFolder(“Build”), minimumCoverage: 50, excludedTargets: [“DangerSwiftCoverageTests.xctest”])

- Create a folder called `DangerDependencies` on `Sources` with an empty file inside like [Fake.swift](//dnrops/danger-swift-coverage/tree/master/Sources/DangerDependencies/Fake.swift)
- To run `Danger` use `swift run danger-swift command`
- (Recommended) If you are using SPM to distribute your framework, use [Rocket](https://github.com/f-meloni/Rocket), or similar to comment out all the dev depencencies from your `Package.swift`.
This prevents the dev dependencies to be downloaded and compiled with your framework.

#### Marathon
- Add this to your `Dangerfile.swift`

```swift
import DangerSwiftCoverage // package: https://github.com/f-meloni/danger-swift-coverage.git

Coverage.xcodeBuildCoverage(.derivedDataFolder("Build"), 
                            minimumCoverage: 50, 
                            excludedTargets: ["DangerSwiftCoverageTests.xctest"])

• (Recommended) Cache the ~/.danger-swift folder

Gather Coverage

• Enable “Gather the Coverage” on Xcode

or, on your CI, execute:

xcodebuild test -scheme DangerSwiftCoverage-Package -derivedDataPath Build/ -enableCodeCoverage YES

Custom XCResultBundle path

If you are using the -resultBundlePath parameter on xcodebuild you will need to use:

Coverage.xcodeBuildCoverage(.xcresultBundle("Build/bundlePath.xcresult"), 
                            minimumCoverage: 50, 
                            excludedTargets: ["DangerSwiftCoverageTests.xctest"])

Swift Package Manager

From Swift 5.0 you can gather the coverage from SPM with the --enable-code-coverage=true flag For SPM coverage add to your Dangerfile:

Coverage.spmCoverage(minimumCoverage: 50)
