Failed to load ApplicationContext in Spring Controller E2E tests

I am running end2end tests for controllers in a spring boot maven project, individually these types of tests work for me, but if I run them in conjunction with the rest of the test the following error appears:

java.lang.IllegalStateException: Failed to load ApplicationContext

This is an example of the end2end tests that I am running:

@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment=SpringBootTest.WebEnvironment.MOCK)
@AutoConfigureMockMvc
public class CategoryControllerE2ETests {


    @Autowired
    private MockMvc mockMvc;    

    // List Fields Postive Case
    @WithMockUser(username="admin1", authorities= {"admin"})
    @Test
    void testListAll() throws Exception {
        mockMvc.perform(get("/categories/all")).andExpect(status().isOk())
                .andExpect(model().attributeExists("categories")).andExpect(view().name("categories/list"));
    }
}

It appears that is trying to create admin1 with an id that is already in use (of the users type admin there is only admin1). I have tried another user that does not exist in the data.sql, but the error persists, the application uses a hsqldb database.

Data.sql:

INSERT INTO users(username,password,enabled) VALUES ('admin1','4dm1n',TRUE);
INSERT INTO authorities VALUES ('admin1','admin');
