Method Detail

matches
public boolean matches(java.lang.Object o)
Description copied from interface:Matcher
Evaluates the matcher for argument item. This method matches against Object, instead of the generic type T. This is because the caller of the Matcher does not know at runtime what the type is (because of type erasure with Java generics). It is down to the implementations to check the correct type.- Parameters:
o
- the object against which the matcher is evaluated.- Returns:
true
if item matches, otherwisefalse

describeTo
public void describeTo(Description buffer)
Description copied from interface:SelfDescribing
Generates a description of the object. The description may be part of a a description of a larger object of which this is just a component, so it should be worded appropriately.- Parameters:
buffer
- The description to be built or appended to.
-
isIn

Creates a matcher that matches when the examined object is found within the specified collection. For example:assertThat("foo", isIn(Arrays.asList("bar", "foo")))
- Parameters:
collection
- the collection in which matching items must be found

isIn
public static <T> Matcher<T> isIn(T[] elements)
Creates a matcher that matches when the examined object is found within the specified array. For example:assertThat("foo", isIn(new String[]{"bar", "foo"}))
- Parameters:
elements
- the array in which matching items must be found
-
isOneOf
public static <T> Matcher<T> isOneOf(T... elements)
Creates a matcher that matches when the examined object is equal to one of the specified elements. For example:assertThat("foo", isIn("bar", "foo"))
- Parameters:
