Constant Summary collapse

TEST_DATA =

the path to the test configuration file

File.join(__dir__, '../../resources/tests.yaml')
GROUPS =

map each group (e.g. “jvm”) to an array of its member IDs (e.g. [“java”, “kotlin”, “scala”])

Hash.new { |h, k| h[k] = [] }.with_indifferent_access
TESTS =

the top-level hash in tests.yaml. keys are test IDs (e.g. “ruby”); values are test specs

YAML.safe_load(File.read(TEST_DATA)).with_indifferent_access
