本文介绍了FlashBuilder4 Beta和FlexUnit环境下进行测试驱动开发所用到的各种断言方法，如assertEquals、assertTrue等，并解释了这些方法的具体含义及用法。

Assertion method	Meanings
assertEquals	Asserts that two values are equal.
assertContained	Asserts that the first string is contained in the second one.
assertNotContained	Asserts that the first string is not contained in the second one.
assertFalse	Asserts that a condition is false.
assertTrue	Asserts that a condition is true.
assertMatch	Asserts that a string matches a regular expression (regexp).
assertNoMatch	Asserts that a string doesn't match a regexp.
assertNull	Asserts that an object is null.
assertNotNull	Asserts that an object is not null.
assertNotUndefined	Asserts that an object is defined.
assertUndefined	Asserts that an object is undefined.
assertStrictlyEquals	Asserts that two objects are strictly identical.
assertObjectEquals	Asserts that two objects are equal.

断言方法要求三个参数：一个包括字符串信息，另两个参数参与比较。字符串参数包含了测试失败时的描述信息。例如：

assertEquals("Error testing the application state", state, 1);

如果不传入该消息参数，FlexUnit将使用缺省信息。

在编辑器中键入Assert. 你可以通过代码提示功能看到可以使用的全部断言方法。
