AssertTrue vs AssertEquals for ints [closed]

2019-03-27 15:37发布

问题:

Should we use assertEquals or assertTrue for comparing primitive types specifically ints? Is there a preference, if so why ? I'd like to know the pros and cons of each approach.

回答1:

assertEquals() gives a useful default error message on failure, like "expected X but got Y", but assertTrue() can't. Use the more specific applicable method here, which is assertEquals().



回答2:

assertEquals() is to test the equality of your expected value with the returning value. Whereas assertTrue() is to check for a condition. Having said that, you can also say

If you have a condition like.

String x = "abc";
String y = "abc";

assertEquals(x, y);

You can also change it to

assertTrue(x.equals(y));

It is just another way of asserting what you expect.
