Method Details

matchesSafely

public boolean matchesSafely(T obj)

Description copied from class: TypeSafeMatcher

Check if the item matches. The item will already have been checked for the specific type and will never be null. Subclasses should implement this.

Specified by:

matchesSafely in class TypeSafeMatcher<T>

Parameters:

obj - the type safe item to match against.

Returns:

boolean true/false depending if item matches matcher.

describeMismatchSafely

public void describeMismatchSafely(T item,
 Description mismatchDescription)

Description copied from class: TypeSafeMatcher

Describe the mismatch. The item will already have been checked for the specific type and will never be null. Subclasses should override this.

Overrides:

describeMismatchSafely in class TypeSafeMatcher<T>

Parameters:

item - the type safe item to match against.

mismatchDescription - the mismatch description.

describeTo

public void describeTo(Description description)

Description copied from interface: SelfDescribing

Generates a description of the object. The description may be part of a description of a larger object of which this is just a component, so it should be worded appropriately.

Parameters:

description - The description to be built or appended to.

hasProperty

public static <T> Matcher<T> hasProperty(String propertyName)

Creates a matcher that matches when the examined object has a JavaBean property with the specified name. For example:

assertThat(myBean, hasProperty("foo"))

Type Parameters:

T - the matcher type.

Parameters:

propertyName - the name of the JavaBean property that examined beans should possess

Returns:

The matcher.
