+## 結合テスト
+
+```kotlin

+@AutoConfigureDataNeo4j

+
+
+    @Autowired
+    private lateinit var mockMvc: MockMvc

+    @Test
+    fun tagの作成() {
+        mockMvc

+                .withDisabledServer()
+                .build()
+        }
+
+        @DynamicPropertySource

+            registry.add("spring.neo4j.authentication.password", Supplier { null })
+        }
+
+        @AfterAll
+        @JvmStatic
+        fun stopNeo4j() {
+            embeddedDatabaseServer.close()
+        }
+    }
+}
+```
+
+試してないけどSpring Data Neo4jのRepositoryも使えると思う
