What is the difference between using the two following statements in a cucumber step definition? When I tested them in Rubular, they both worked in all the cases I could imagine. In the case of the second, my syntax highlighting is more likely to look good (no extra double quote to mess things up).
在黄瓜步骤定义中使用以下两个语句的区别是什么?当我用小舌做测试时，它们都适用于我能想到的所有情况。在第二种情况下，我的语法突出显示更可能看起来不错(没有额外的双引号把事情搞砸)。
Even in the Stack Overflow syntax highlighting, it gets goofed up on the first. What are the advantages of the more common first example?
即使在堆栈溢出语法突出显示中，第一次也会出错。比较常见的第一个例子的优点是什么?
Given /^My name is "([^"]*)"$/ do |myname|
Given /^My name is "(.+)"$/ do |myname|

[^"]* means N (N>=0) characters except "
[^ "]*意味着N(N > = 0)字符除了“
.+ means N (N>0) characters including "
.+表示N (N>)个字符，包括"
If the subject is more than 1 char, and without quote mark("), the two regex patterns are equal.
如果主题超过1个字符，并且没有引号(“)，两个正则表达式是相等的。
But, consider this string: My name is "special_name_contain_"_laugh" Run your pattern again, they are NOT the same :)
但是，请考虑这个字符串:我的名字是“special_name_contain_”“_laugh”，再次运行您的模式，它们不是相同的:)

The first will not break when provided the following:
当提供以下内容时，第一个不会中断:
My name is "Henry James" and some other condition is "something else"
The first regular expression limits the characters inside the quoted string to non-quote characters - thus it will only pick up Henry James. The second regular expression matches a quote character followed by anything else (including other quote characters) and then an ending quote character - so myname in the second case would be:
第一个正则表达式将引用字符串中的字符限制为非引用字符——因此它只会选择Henry James。第二个正则表达式匹配一个引号字符，后面跟着任何其他字符(包括其他引号字符)，然后是一个引号字符——因此第二个例子中的myname将是:
Henry James" and some other condition is "something else
Which means that you can have only one quoted value in your test case - which is far more limiting than the limitation of the first regular expression (you can only have quoted values that do not contain a quote character).
这意味着您可以在您的测试用例中只有一个引用值——这比第一个正则表达式的限制要限制得多(您只能引用不包含引号字符的值)。

I'm not a ruby guru, however the first regular expression means:
我不是ruby的权威，但是第一个正则表达式意味着:
-
^Start of line - ^开始行
-
My name is "the literal string followed by a" - 我的名字是"字符串后面跟着a "
-
(starts a capture group - (启动捕获组
-
[starts a character class - 开始一个角色类
-
^"in a character class,^means "not", so in this case it means anything but a" - ”^ ^字符类,意思是“不”,所以在这种情况下这意味着除了“
-
]end of character class - 结束字符类。
-
*any number of the preceding, including 0 matches - *前面的任何数字，包括0匹配。
-
"a quote character - “引用字符
-
$end of line - 美元行结束
The second one, everything is the same as above, except in the character class [] you have:
第二个，所有的都和上面一样，除了在人物类[]中你有:
-
."any character" - 。“任何字符”
-
+one or more of the preceding - +前面的一个或多个
The difference between + and * is that + requires atleast one of the preceeding, but * will also match if there are zero of the preceding.
+和*之间的区别是+至少需要一个前面的标记，但如果前面的标记为0，*也将匹配。
