java - I need Matcher<String> containsString(Matcher<String> matcher), am I doing something wrong? -

i'd check string contains string, ignoring case. basically, i'd this:

assertthat(dialogtitle.gettext(), containsstring(equaltoignoringcase("diagram"))); 

but couldn't find matcher<string> takes matcher<t>. there different way how accomplish this?

you can implement own matcher extending substringmatcher org.hamcrest.core package:

public class stringcontainsignoringcase extends substringmatcher {     public stringcontainsignoringcase(string substring) {         super(substring);     }      @override     protected boolean evalsubstringof(string s) {         return s.tolowercase().contains(substring.tolowercase());     }      @override     protected string relationship() {         return "containing (ignoring case)";     }      public static matcher<string> containsstringignoringcase(string substring) {         return new stringcontainsignoringcase(substring);     }  } 

usage:

assertthat(dialogtitle.gettext(), stringcontainsignoringcase.containsstringignoringcase("diagram")); 

and readability can make static import of course , get:

assertthat(dialogtitle.gettext(), containsstringignoringcase("diagram"));

the matcher asking in master branch of javahamcrest project unfortunately not in latest release of hamcrest (1.3).
