Ruby test runs showed only console text: there was no Ruby output parser and test_*.rb was not a test file. A Minitest parser now builds the test tree (class, test, status, time, failure text) from verbose output (-v / TESTOPTS=-v), test_*.rb counts as a test file, jump to source finds the class and then its def, and the gutter gets a run action per test method (coloured by the last result) and per test class and module that holds test classes; one test, class or module runs with --name=....
The streaming Find in Files helper the jump to source uses moved from the search feature to src/platform, so the run feature doesn't import another feature.
