Danger-slather

A Danger plugin that show code coverage of a Xcode project and file by file using Slather. Add warnings or fail the build if a minimum coverage are not achieved. It uses Slather Framework for calculate coverage, so it's required to configure the slather object before using it.

How does it look?

	1 Error
🚫	Total coverage less than 80%

	1 Warnings
⚠️	AppDelegate.swift has less than 50% code coverage

Code coverage

Total coverage: 35.0

File	Coverage
AppDelegate.swift	10.00
ViewController.swift	20.00
ViewController2.swift	30.00
ViewController3.swift	40.00
ViewController4.swift	50.00
ViewController5.swift	60.00

Installation

$ gem install danger-slather

Usage

First configure the slather object:

slather.configure("Path/to/my/project.xcodeproj", "MyScheme")

For a more complex case:

slather.configure("Path/to/my/project.xcodeproj", "MyScheme", options: {
  workspace: 'Path/to/my/workspace.xcworkspace',
  build_directory: 'Path/to/my/build_directory',
  ignore_list: ['ignore file 1', 'ignore file 2'],
  ci_service: :travis,
  coverage_access_token: 'acc123123123123',
  coverage_service: :terminal,
  source_directory: 'Path/to/my/source_directory',
  output_directory: 'Path/to/my/output_directory',
  input_format: 'profdata',
  binary_file: 'Path/to/my/output_directory',
  decimals: 2
  post: false      
})

For a more complete documentation of all support configuration see Slather

Than just add this line to your Dangerfile:

slather.notify_if_coverage_is_less_than(minimum_coverage: 80)
slather.notify_if_modified_file_is_less_than(minimum_coverage: 60)
slather.show_coverage
