The stacktrace line isn't the one you should be running. The test outputs
the file and line to run immediately following the test message. Here's an
example:
1) test run/1 raises exception when invalid switch is passed
(Mix.Tasks.Conduit.Gen.BrokerTest)
*test/mix/tasks/conduit.gen.broker_test.exs:17*
Expected exception OptionParser.Parserror but got
OptionParser.ParseError (1 error found!
--something-broken : Unknown option)
code: assert_raise OptionParser.Parserror, fn ->
stacktrace:
(elixir) lib/option_parser.ex:231: OptionParser.parse!/2
(conduit) lib/mix/tasks/conduit.gen.broker.ex:26:
Mix.Tasks.Conduit.Gen.Broker.run/1
test/mix/tasks/conduit.gen.broker_test.exs:18: (test)
