当我在Kotlin中的嵌套类中指定测试时，如下所示...
import org.junit.jupiter.api.*
class ParentTest
{
@Nested
class NestedTest
{
@Test
fun NotFoundTest() {}
}
@Test
fun FoundTest() {}
}
... JUnit在使用gradle运行测试时无法识别它.只有FoundTest人被找到并跑掉了.
我使用的是JUnit 5.1、Kotlin 1.2.30和Gradle 4.6.
Defining the nested class as an inner class resolves this issue.
class ParentTest
{
@Nested
inner class NestedTest
{
@Test
fun InnerTestFound() {}
}
@Test
fun FoundTest() {}
}
As Sam Brannen indicates、"by default, a nested class in Kotlin is similar to a 102 class in Java"和the JUnit documentation indicates:
Only non-static nested classes (i.e. inner classes) can serve as @Nested test classes.
Marking the class as inner in Kotlin compiles to a non-static Java class.
