public class AssertMatches
extends RegexMatcher
implements ValueAssertion<Matcher>

Class AssertMatches matches the given regular expression patternString against the whole argument Tuple by joining each individual element of the Tuple with a tab character (\t). See AssertMatchesAll if you need to match the patternString regex against each individual tuple element.

This operation uses Matcher internally, specifically the method Matcher.find().

Note a null valued argument passed to the parser will be converted to an empty string ("") before the regex is applied.

Any Object value will be coerced to a String type via its toString() method.
