Ruby 1.9.1-rc1 にて、Test::Unit::Assertions#assert_match が
assertionsの数を1回あたり2ずつ増やしています。
なお、failure の数は正しく増えています。

以下の例では、2回しかassert_matchを実行しないはずなのに"4 assertions"になっています。

$ ruby191rc1 -v -r test/unit -e 'class A<Test::Unit::TestCase; def test_a; assert_match(/a/, "a"); end; def test_b; assert_match(/b/, "a"); end; end'

  1) Failure:
test_b(A) [-e:1]:
Expected /b/ to match "a".

2 tests, 4 assertions, 1 failures, 0 errors, 0 skips

1.8.7 では正しくカウントしています。

% ruby187p72 -v -r test/unit -e 'class A<Test::Unit::TestCase; def test_a; assert_match(/a/, "a"); end; def test_b; assert_match(/b/, "a"); end; end'
