Install the gem and add to the application's Gemfile by executing:
$ bundle add affected_tests
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install affected_tests
affected_tests support 3 engines to find out test, source relation:
- rotoscope (default)
- coverage
- calleree
each engine require its library, so you need to add proper gem according to your selection(except coverage which is stdlib).
on spec/spec_helper.rb
:
require "affected_tests"
require "affected_tests/rspec"
AffectedTests.setup(
engine: :rotoscope,
project_path: File.expand_path("../../", __FILE__),
test_dir_path: "spec/",
output_path: "log/affected-tests-map.json",
revision: "1cf22fdb86e2b2d6107" # or git rev-parse HEAD > REVISION
)
this will write associated test files per file on log/affected-tests-map.json
