Switching from JUnit 4 to JUnit 5: tutorial does not describe required updates to imports

[mristau-gn]

I'm not an experienced java developer so I may be missing something, but when I went thru this section my build started to fail. I had to look in the repo to realize I needed to also update the imports.

My BlogApplicationTests.kt at the end of this section, which works, is:

package blog

import org.junit.jupiter.api.Test
import org.junit.jupiter.api.extension.ExtendWith
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.test.context.junit.jupiter.SpringExtension

@ExtendWith(SpringExtension::class)
@SpringBootTest
class BlogApplicationTests {

	@Test
	fun contextLoads() {
	}

}
