Camunda migration

Hi Team,
I am trying to migrate camunda version from 7.8.14 to 7.17.0.
However, i am getting error in Junit( test classes).
using jdk 17, springboot-2.6.7.

not able to recognize some packages e.g
org.springframework.boot.test.context.SpringBootTest;
org.springframework.test.context.junit4.SpringRunner;
org.camunda.bpm.engine.test.assertions.bpmn.BpmnAwareAssertions.assertThat

Any suggestion/help will be appreciated.

Any idea ??
