Grails / groovy测试-assert和assertEquals方法之间的任何区别

Question

I have numerous Grails unit and integration groovy test classes.

Originally I used methods such as assertEquals, assertNull, assertTrue, assertFalse, etc.

assertEquals 0, User.list().size()

but recently I've been preferring to use a straight assert:

assert User.list().size() == 0

Is there any difference between these 2 approaches?

Answer 1

The assertEquals is using a JUnit assertion, whereas the assert is using groovy's power assert . The power assert gives you much nicer error messages and is built-in to the language. You should generally use that one when you can.

Answer 2

如果assertEquals失败，则抛出AssertionError ，但如果使用assert ，则不会抛出此类错误，但是它会以常规方式进行断言并在失败时提供良好的断言消息。
