我有一个这样的测试（语言是Kotlin）：
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
class MyTest {
private var i: Int = 0
@RetryingTest(3)
fun go() {
Assertions.assertEquals(1, 2, "wow ${++i}")
}
}
此测试的所有 3 次调用均失败，最后一次调用留下以下痕迹：
org.opentest4j.TestAbortedException: wow 1 ==>

如您所见，日志中的任何位置都没有打印
wow 3如何查看上次调用产生的错误？
我像这样尝试了你的测试。
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
class MyTest {
private var i: Int = 0
@RepeatedTest(3)
fun go() {
Assertions.assertEquals(1, 2, "wow ${++i}")
}
}
然后我得到了这个日志。
org.opentest4j.AssertionFailedError: wow 1 ==>
Expected :1
Actual :2
