Interface ParametrizedMatcher

  • public interface ParametrizedMatcher
    Implement this interface to use with parametrized matchers. Sample usage 
         

     Matcher<?> divisionMatcher = new DivisionMatcher();
     assertJsonEquals("{\"test\": \"${json-unit.matches:isDivisibleBy}3\"}", "{\"test\":5}", JsonAssert.withMatcher("isDivisibleBy", divisionMatcher));

     private static class DivisionMatcher extends BaseMatcher<Object> implements ParametrizedMatcher {
       private BigDecimal param;

       public boolean matches(Object item) {
           return ((BigDecimal)item).remainder(param).compareTo(ZERO) == 0;
       }

       public void describeTo(Description description) {
           description.appendValue(param);
       }

       public void describeMismatch(Object item, Description description) {
           description.appendText("It is not divisible by ").appendValue(param);
       }

       public void setParameter(String parameter) {
           this.param = new BigDecimal(parameter);
       }
   }
