Junit5 断言导入

Question

So, I included Junit5 to my maven project and it kind of works, but anyway when I try to import assertions to a test I can only put org.junit.jupiter.api.Assertions.* without beign able to specify some precise assertion and in the code I have to write for example Assertions.assertThrows() .

Why can't I pick any specific assertion from the list?

What could be the problem?

Answer 1

If you only want to import a single method, you have to use a static import, like this:

import static org.junit.jupiter.api.Assertions.assertThrows;

Then you can simply use it like:

assertThrows(Exception.class, () -> ...)

Answer 2

You can import specific assertions by using a static import:

import static org.junit.jupiter.api.Assertions.assertFalse;
import static org.junit.jupiter.api.Assertions.assertTrue;

This works for me in eclipse…
