 As described in the <<testing#testcontext-junit-jupiter-di#spring-web-reactive, dedicated section>>,
 JUnit 5 allows constructor injection of beans which is pretty useful with Kotlin
 in order to use `val` instead of `lateinit var`. You can use
-{api-spring-framework}/test/context/TestConstructor.html[`@TestConstructor(autowire = true)`]
+{api-spring-framework}/test/context/TestConstructor.html[`@TestConstructor(autowireMode = AutowireMode.ALL)`]
 to enable autowiring for all parameters.
