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?

Code coverage

Total coverage: 35.0

Powered by Slather

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
