@Test public void testDeleteMedication() throws Exception { mockMvc.perform(delete("/clients/1/medications/2") .header("If-Match", testClient.getETag())) .andExpect(status().isOk()); mockMvc.perform(get("/clients/1/medications")) .andExpect(status().isOk()) .andExpect(jsonPath("$", hasSize(1))) .andExpect(content().contentType(contentType)) .andExpect(jsonPath("$[0].medicationName", is("Name"))); }
