ruby - Mapping multiple test classes to the same file for autotest -

i'm using standalone autotest in projects along minitest. in 1 of projects, have single file (validation.rb) validates document different internal format levels. (a level 2 document has more features level 1 document.)

testing validation particular level requires repeatedly loading in known-valid document, subtly mutating in broken way, , ensuring broken. in short:

class testvalidation < minitest::unit::testcase   def setup     @l1 = document.load( l1doc )   end   def test_valid     assert @l1.valid_level_1?   end   def test_unbalanced_data     @l1.instance_eval{ @tracks[0].data.pop }     refute @l1.valid_level_1?, "validation must ensure tracks have same amount of data"   end   # many more tests level 1 here end 

the problem autotest (as far can tell) knows tests run based on name of test classes. testvalidation have tests automatically run when validation.rb changed.

without autotest, have named above class testl1validation, , created new class testl2validation loaded different document. doing breaks autotest, however, unless break out validation l1validation.rb , l2validation.rb.

how can name files or tests, or set tests, autotest run multiple test classes when single source file changes?

you can add custom mappings autotest. here's 1 way of doing it: create autotest directory @ same level lib , test directories.

add autotest/discover.rb:

$load_path.unshift file.expand_path('../', file.dirname(__file__)) autotest.add_discovery { "my_rules" } 

add autotest/my_rules.rb:

require 'autotest'  class autotest::my_rules < autotest   def initialize     super      add_mapping(%r%^lib/valid.rb$%, true) { |filename, _|       files_matching %r%^test/test_.*\.rb$%     }   end end 

this add custom mapping: whenever lib/valid.rb files has changed, re-run test_*.rb files in test directory.
