how to get bottom error message from a nested exception using mockmvc

I am getting a nested exception like below for my Junit tests:

 Caused by: com.exception.Test1RestException: operation failed for test1 
at com.testController.tests(Test1Controller.java:123)

............................

  Caused by: com.exception.Test2Exception: operation failed for test2 
at com.testController.tests(Test2Controller.java:456)

.............................

 Caused by: com.exception.Test3RestException: operation failed for test3 
at com.testController.tests(Test2Controller.java:789)

I want to verify "operation failed for test3 " using mockmvc,used below

code for that

org.assertj.core.api.Assertions
        .assertThatThrownBy(() -> 
 mockMvc.perform(fileUpload("/test/abc").file((MockMultipartFile) files))
              .andExpect(status().isOk()))
        .hasMessageContaining(operation failed for test3)

But I am getting expected error message as "operation failed for test1",any pointers to reach till bottom message here from my junit

Solution

  • it worked by using .hasStackTraceContaining(message) ,method call
