#run_with_callbacks_and_mocha(result) {|Test::Unit::TestCase::STARTED, name| ... } ⇒ Object

Doubly unfortunate: mocha does the same so we have to hax their hax.

Yields:

  • (Test::Unit::TestCase::STARTED, name)

#run_with_callbacks_and_testunit(result) {|Test::Unit::TestCase::STARTED, name| ... } ⇒ Object

This redefinition is unfortunate but test/unit shows us no alternative.

Yields:

  • (Test::Unit::TestCase::STARTED, name)
