情况很简单。我有一个这样的模块(first.rb):
def ret_s(l)
return "one" if l == 1
return "twoe" if l == 2
return "threee" if l == 3
end
def ret_l(str)
return 1 if str == "one"
return 2 if str == "two"
return 4 if str == "three"
end
和一个测试类(TestFist.rb):
require 'test/unit'
require './first'
class TestFirst < Test::Unit::TestCase
def test_fist
assert_equal("one",ret_s(1))
assert_equal("two",ret_s(2))
assert_equal("three",ret_s(3))
end
def test_second
assert_equal(1,ret_l("one"))
assert_equal(2,ret_l("two"))
assert_equal(3,ret_l("three"))
end
end
运行此测试时,为什么我会得到这样的答案:
$ ruby TestFirst.rb
Run options:
# Running tests:
FF
Finished tests in 0.001000s, 2000.0000 tests/s, 5000.0000 assertions/s.
1) Failure:
test_fist(TestFirst) [TestFirst.rb:9]:
<"two"> expected but was
<"twoe">.
2) Failure:
test_second(TestFirst) [TestFirst.rb:17]:
<3> expected but was
<4>.
2 tests, 5 assertions, 2 failures, 0 errors, 0 skips
最后一行让我觉得我做错了什么。我会期待这样的事情:
2 次测试,6 次断言,3 次失败,0 次错误,0 次跳过
不是
2 次测试,5 次断言,2 次失败,0 次错误,0 次跳过
