我刚从watir 4.0.2升级到watir 2.0.4，我收到以下错误，
C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:60:in `gem_original
_require': no such file to load -- watir/testcase (LoadError)
我搜索了错误，但无法找到解决方案。

对此有什么想法吗？
答案 0 :(得分：1)
watir/testcase最近从Watir中删除了。我找不到它的删除时间，但信息位于CHANGES文件或Git history。

虽然离开Watir :: TestCase可能会更好，但如果你确实需要或想要使用它，你可以通过从3.0复制文件来重新创建它。
假设您使用的是Ruby 1.8，默认情况下仍然安装了测试单元gem，您可以执行以下操作：
1）使用以下代码创建名为“watir_testcase.rb”的文件，该文件基本上是3.0版本的testcase.rb和assertions.rb文件的副本：
require 'watir-classic'
require 'test/unit'
require 'test/unit/assertions'
module Watir
# Verification methods used by Watir::TestCase
module Assertions
include Test::Unit::Assertions
# Log a failure if the boolean is true. The message is the failure message logged.
# Whether true or false, the assertion count is incremented.
def verify boolean, message = 'verify failed.'
add_assertion
add_failure message.to_s, caller unless boolean
end
def verify_equal expected, actual, message=nil
full_message = build_message(message, <<EOT, expected, actual)
<?> expected but was
<?>.
EOT
verify(expected == actual, full_message)
end
def verify_match pattern, string, message=nil
pattern = case(pattern)
when String
Regexp.new(Regexp.escape(pattern))
else
pattern
end
full_message = build_message(message, "<?> expected to be =~\n<?>.", string, pattern)
verify(string =~ pattern, full_message)
end
end
end
module Test::Unit::Assertions
def assert_false(boolean, message=nil)
_wrap_assertion do
assert_block("assert should not be called with a block.") { !block_given? }
assert_block(build_message(message, "<?> is not false.", boolean)) { !boolean }
end
end
end
module Watir
# This is a 'test/unit' testcase customized to exeucte test methods sequentially by default
# and extra assertions
#
class TestCase < Test::Unit::TestCase
include Watir::Assertions
@@order = :sequentially
def initialize name
throw :invalid_test if name == :default_test && self.class == Watir::TestCase
super
end
class << self
attr_accessor :test_methods, :order
def test_methods
@test_methods ||= []
end
def order
@order || @@order
end
def default_order= order
@@order = order
end
def sorted_test_methods
case order
when :alphabetically then test_methods.sort
when :sequentially then test_methods
when :reversed_sequentially then test_methods.reverse
when :reversed_alphabetically then test_methods.sort.reverse
else raise ArgumentError, "Execute option not supported: #{@order}"
end
end
def suite
suite = Test::Unit::TestSuite.new(name)
sorted_test_methods.each do |test|
catch :invalid_test do
suite << new(test)
end
end
if (suite.empty?)
catch :invalid_test do
suite << new(:default_test)
end
end
return suite
end
def method_added id
name = id.id2name
test_methods << name if name =~ /^test./
end
def execute order
@order = order
end
end
public :add_assertion
end
end
2）在测试用例文件中，更改：
require 'watir/testcase'
要求新创建的文件：
require './watir_testcase'
（确保路径对于保存文件的位置是正确的）
