将字符串与rspec中的正则表达式进行比较？

Question

我在做

expect(@link.url_address == 'abc').to be_true

但 url_address 可能在abc 之后有其他文本，所以我正在尝试

expect(@link.url_address =~ 'abc').to be_true

但我得到了

Failure/Error: expect(@link.url_address =~ /abc/).to be_true
   expected  to respond to `true?`

我也试过

expect(@link.url_address).to =~ /abc/

但我明白了

 Failure/Error: expect(@link.url_address).to =~ /abc/
 ArgumentError:
   The expect syntax does not support operator matchers, so you must pass a matcher to `#to`.

Answer 1

试试这个：

expect(@link.url_address).to match(/abc/)
