如何 运行 现有测试代码 Ruby 2.2
How to run existing test code on Ruby 2.2
以下代码(没有 Gemfile)适用于 Ruby 2.1.1,但不适用于 Ruby 2.2.0
require "bundler/setup"
gem "minitest", "4.7.5"
require "test/unit"
class TestFoo < Test::Unit::TestCase
def test_foo
assert true, "Useless mesage"
skip "Skip works"
end
end
在 Ruby 2.1.1 上,我得到
Run options:
# Running tests:
[1/1] TestFoo#test_foo = 0.00 s
1) Skipped:
TestFoo#test_foo [test_220.rb:8]:
Skip works
Finished tests in 0.004435s, 225.4791 tests/s, 225.4791 assertions/s.
1 tests, 1 assertions, 0 failures, 0 errors, 1 skips

但是在 Ruby 2.2.0 上,我得到

我怀疑这是因为changes associated with Ruby 2.2.0:
Update test-unit 3.0.8 (removed from repository but bundled in
tarball)
Update minitest 5.4.3 (removed from repository but bundled in tarball)
如何使代码在 Ruby 2.2 上运行,最好是代码更改量最少?
在 Ruby 2.2 之前,test/unit
只是 minitest
的薄包装。即使您的测试用例继承自 Test::Unit::TestCase
,您实际上使用的是 minitest 断言。因此 skip
有效,这是 minitest
.
的一个特征
标准 Ruby 2.2 发行版捆绑了 test-unit 3.0.8
和 minitest 5.4.3
,但不包括之前存在的集成。请注意,它们实际上是 2 个独立的测试框架 - 本质上是两个独立的 gem。
我提出 2 个选项:
1。使用 test-unit
- rubydoc
您的测试可以保留 Test::Unit::TestCase
基础 class,但您需要调整断言以使用 test-unit
基础。
例如,将skip
替换为omit
:
require "test/unit"
class TestFoo < Test::Unit::TestCase
def test_foo
assert true, "Useless mesage"
omit "Omit works"
end
end
2。使用 minitest
- rubydoc
您将继续使用您知道的断言,但您需要 require "minitest/autorun"
并将基数 class 切换为 Minitest::Test
:
require "minitest/autorun"
class TestFoo < Minitest::Test
def test_foo
assert true, "Useless mesage"
skip "Skip works"
end
end
test-unit backports 已包装成 gem:test-unit-minitest
