How can I assert hasProperty with a Java Record?

I have a piece of code in a test that checks that a list of results contains certain properties, using Hamcrest 2.2:

assertThat(result.getUsers(), hasItem(
    hasProperty("name", equalTo(user1.getName()))
));
assertThat(result.getUsers(), hasItem(
    hasProperty("name", equalTo(user2.getName()))
));

This worked perfectly fine when NameDto was a normal class. But after I changed it to a Record, Hamcrest's hasProperty complains about there being no property named name:

java.lang.AssertionError:
Expected: a collection containing hasProperty("name", "Test Name")
     but: mismatches were: [No property "name", No property "name"]

Is there some other matcher I can use to achieve the same matching as before? Or some other workaround I can use to get it to work with records?

The accessor method of a record field does not follow the regular JavaBeans convention, so the User record (say public record User (String name) {}) will have an accessor method whose name is name() instead of getName().

I suspect this is why Hamcrest considers there is no property. I don't think there is a way out-of-the-box in Hamcrest other than to write a custom Matcher.

Here's a custom HasRecordComponentWithValue inspired by the existing HasPropertyWithValue. The main utility leveraged here is Java's Class.getRecordComponents():

public static class HasRecordComponentWithValue<T> extends TypeSafeDiagnosingMatcher<T> {
    private static final Condition.Step<RecordComponent,Method> WITH_READ_METHOD = withReadMethod();
    private final String componentName;
    private final Matcher<Object> valueMatcher;

    public HasRecordComponentWithValue(String componentName, Matcher<?> valueMatcher) {
        this.componentName = componentName;
        this.valueMatcher = nastyGenericsWorkaround(valueMatcher);
    }

    @Override
    public boolean matchesSafely(T bean, Description mismatch) {
        return recordComponentOn(bean, mismatch)
                  .and(WITH_READ_METHOD)
                  .and(withPropertyValue(bean))
                  .matching(valueMatcher, "record component'" + componentName + "' ");
    }

    private Condition.Step<Method, Object> withPropertyValue(final T bean) {
        return new Condition.Step<Method, Object>() {
            @Override
            public Condition<Object> apply(Method readMethod, Description mismatch) {
                try {
                    return matched(readMethod.invoke(bean, NO_ARGUMENTS), mismatch);
                } catch (Exception e) {
                    mismatch.appendText(e.getMessage());
                    return notMatched();
                }
            }
        };
    }

    @Override
    public void describeTo(Description description) {
        description.appendText("hasRecordComponent(").appendValue(componentName).appendText(", ")
                   .appendDescriptionOf(valueMatcher).appendText(")");
    }

    private Condition<RecordComponent> recordComponentOn(T bean, Description mismatch) {
        RecordComponent[] recordComponents = bean.getClass().getRecordComponents();
        for(RecordComponent comp : recordComponents) {
            if(comp.getName().equals(componentName)) {
                return matched(comp, mismatch);
            }
        }
        mismatch.appendText("No record component \"" + componentName + "\"");
        return notMatched();
    }


    @SuppressWarnings("unchecked")
    private static Matcher<Object> nastyGenericsWorkaround(Matcher<?> valueMatcher) {
        return (Matcher<Object>) valueMatcher;
    }

    private static Condition.Step<RecordComponent,Method> withReadMethod() {
        return new Condition.Step<RecordComponent, java.lang.reflect.Method>() {
            @Override
            public Condition<Method> apply(RecordComponent property, Description mismatch) {
                final Method readMethod = property.getAccessor();
                if (null == readMethod) {
                    mismatch.appendText("record component \"" + property.getName() + "\" is not readable");
                    return notMatched();
                }
                return matched(readMethod, mismatch);
            }
        };
    }

    @Factory
    public static <T> Matcher<T> hasRecordComponent(String componentName, Matcher<?> valueMatcher) {
        return new HasRecordComponentWithValue<T>(componentName, valueMatcher);
    }
}
