Use flexible pluralization
Add a ? immediately following the pluralized word:
Then /^the users? should receive an email$/ do# ...end
The ? specifies that you’re looking for zero or more of the proceeding character. So the above example will capture both user and users.
Use non-capturing groups to help steps read naturally
You can create non-capturing groups by adding a ?: to the beginning of a otherwise normal group (e.g. (?:some text) rather than (some text)). This is treated exactly like a normal group except that the result will is not captured and thus not passed as an argument to your step definition. Here are two common examples:
And /^once the files? (?:have|has) finished processing$/ do # ... end
When /^(?:I|they) create a profile$/ do # ... end
