Method Detail

hasProperty

public static <T> org.hamcrest.Matcher<? super T> hasProperty(String chain,
                                                              org.hamcrest.Matcher<?> valueMatcher)

This matcher is similar to Matchers.hasProperty(java.lang.String) but better!

Sometimes you need to assert on a property that is deep down in the object, and then you would do:

     hasProperty("a", hasProperty("b", hasProperty("c", equalTo("abc")))
 

But with this matcher you can just write:

     hasProperty("a.b.c", equalTo("abc"))
 

It's worth noting that the two above calls are completely equivalent, i.e. this method is implemented in terms of Matchers.hasProperty(java.lang.String).

Type Parameters:

T - type of the thing we assert on

Parameters:

chain - property to check, can be chained (e.g. "a.b.c")

valueMatcher - matcher on the property

Returns:

the matcher

propertiesMatcher

public static <T> org.hamcrest.Matcher<? super T> propertiesMatcher(Map<String,org.hamcrest.Matcher<Object>> values)
