黄瓜正则表达式步骤定义 [英] Cucumber regex step definition

问题描述

有人可以解释两者之间的区别吗

Can someone explain what is the difference between

@When("some text (.*)")

和

@When("^some text ([^\"]*)$")

?

前者在使用简单步骤时有效，但是在使用数据表时，它仅映射到第一个表项.

The former worked when using a straightforward step, but when using a data table it maps only to the first table item.

推荐答案

以下是几个常见正则表达式的说明:

Here is explanation of couple of common regex :

.* 匹配任何内容(或不匹配任何内容)，字面意思是任何字符(换行符除外)0次或多次"

.* matches anything (or nothing), literally "any character (except a newline) 0 or more times"

.+ 至少匹配任何一项

[0-9] 或d 匹配一系列数字(或不匹配)

[0-9] or d matches a series of digits (or nothing)

[0-9] + 或 d + 匹配一个或多个数字

[0-9]+ or d+ matches one or more digits

"[^"] *"匹配双引号中的某项(或不匹配)

"[^"]*" matches something (or nothing) in double quotes

an?匹配a或an(问号使n可选)

an? matches a or an (the question mark makes the n optional)

因此，根据您的问题，不同之处是:

.*将采用除新行以外的所有内容， ([^ \] *)，这将使所有内容也换上新行

.* will take everything except the new lines, ([^\"]*) this will take everything also the new lines
