Creates a matcher that matches when the examined object is logically equal to the specified operand, as determined by calling the Object.equals method on the examined object.

If the specified operand is null then the created matcher will only match if the examined object's equals method returns true when passed a null (which would be a violation of the equals contract), unless the examined object itself is null, in which case the matcher will return a positive match.

The created matcher provides a special behaviour when examining Arrays, whereby it will match if both the operand and the examined object are arrays of the same length and contain items that are equal to each other (according to the above rules) in the same indexes.

For example:
assertThat("foo", equalTo("foo"));
assertThat(new String[] {"foo", "bar"}, equalTo(new String[] {"foo", "bar"}));
/** * Creates a matcher that matches when the examined object is logically equal to the specified * <code>operand</code>, as determined by calling the {@link java.lang.Object#equals} method on * the <b>examined</b> object. * * <p>If the specified operand is <code>null</code> then the created matcher will only match if * the examined object's <code>equals</code> method returns <code>true</code> when passed a * <code>null</code> (which would be a violation of the <code>equals</code> contract), unless the * examined object itself is <code>null</code>, in which case the matcher will return a positive * match.</p> * * <p>The created matcher provides a special behaviour when examining <code>Array</code>s, whereby * it will match if both the operand and the examined object are arrays of the same length and * contain items that are equal to each other (according to the above rules) <b>in the same * indexes</b>.</p> * <p/> * For example: * <pre> * assertThat("foo", equalTo("foo")); * assertThat(new String[] {"foo", "bar"}, equalTo(new String[] {"foo", "bar"})); * </pre> */

Creates a matcher that matches when the examined object is an instance of the specified type, as determined by calling the Class.isInstance(Object) method on that type, passing the the examined object.

The created matcher forces a relationship between specified type and the examined object, and should be used when it is necessary to make generics conform, for example in the JMock clause with(any(Thing.class))

For example:
assertThat(new Canoe(), instanceOf(Canoe.class));
/** * Creates a matcher that matches when the examined object is an instance of the specified <code>type</code>, * as determined by calling the {@link java.lang.Class#isInstance(Object)} method on that type, passing the * the examined object. * * <p>The created matcher forces a relationship between specified type and the examined object, and should be * used when it is necessary to make generics conform, for example in the JMock clause * <code>with(any(Thing.class))</code></p> * <p/> * For example: * <pre>assertThat(new Canoe(), instanceOf(Canoe.class));</pre> */
