[thanksforallthefish]

extensions moved, I think you should use

<dependency>
   <groupId>io.kotest.extensions</groupId>
   <artifactId>kotest-extensions-spring/artifactId>
   <version>1.1.0</version>
   <scope>test</scope>
</dependency>

instead of kotest-extensions-spring-jvm

[Rajkumar Singh]

yes, this one worked. thanks @thanksforallthefish
