+====== Launch WireMock with mappings file of JUnit ======
+===== Problem =====
+在解決整合REST外部服務的腳本錄製問題後，接下來就是應用的問題。我想要解決的問題是「該如何在JUnit中啟用預錄好的腳本，讓它取代我所相依的外部服務，讓測試更穩更快減少假警報呢?」本篇分享我的做法。
+===== How to? =====
+==== WireMockRule ====
+這個方法是官網教的，直接使用JUnit的Rule讓它幫你啟動與關閉WireMockServer；如果要載入預錄腳本，就直接指定mappings的上一層即可。以我的範例來說，預錄腳本是放在./testdata/loadMappings/query/mappings中:
+<code java>
+public class TestWithWireMockRule {
+	@Rule
+	public WireMockRule wireMockRule = new WireMockRule(WireMockConfiguration.options()
+			.port(80)
+			.httpsPort(443)
+			.usingFilesUnderDirectory("./testdata/loadMappings/query"));
+	@Test
+	public void getHttpCode200WhenQueryUser() throws IOException {
+		HttpGet post = new HttpGet("http://localhost/api/users/2");
+		CloseableHttpClient httpClient = HttpClientFactory.createClient();
+		try {
+			CloseableHttpResponse response = httpClient.execute(post);
+			assertEquals(200, response.getStatusLine().getStatusCode());
+		} finally {
+			httpClient.close();
+		}
+	}
+}
+</code>
+==== WireMockServer ====
+如果想要在不同測試案例中，載入不同的腳本，可以自己控制WireMockServer啟動與關閉。寫法和WireMockRule大同小異，因為它其實是extendWireMockServer的。
+<code java>
+public class TestWithWireMockServer {
+	private WireMockServer wireMockServer;
+	@After
+	public void teardown() {
+		wireMockServer.stop();
+	}
+	private void launchWireMockServer(String testdataPath) {
+		wireMockServer = new WireMockServer(WireMockConfiguration.options()
+				.port(80)
+				.httpsPort(443)
+				.usingFilesUnderDirectory(testdataPath));
+		wireMockServer.start();
+	}
+	@Test
+	public void getHttpCode200WhenQueryUser() throws IOException {
+		launchWireMockServer("./testdata/loadMappings/query");
+		HttpGet post = new HttpGet("http://localhost/api/users/2");
+		CloseableHttpClient httpClient = HttpClientFactory.createClient();
+		try {
+			CloseableHttpResponse response = httpClient.execute(post);
+			assertEquals(200, response.getStatusLine().getStatusCode());
+		} finally {
+			httpClient.close();
+		}
+	}
+	@Test
+	public void getHttpCode200WhenUpdateUser() throws IOException {
+		launchWireMockServer("./testdata/loadMappings/update");
+		HttpPatch patch = new HttpPatch("http://localhost/api/users/2");
+		patch.setEntity(new StringEntity("{\"name\":\"morpheus\",\"job\":\"zion resident\"}", "utf-8"));
+		CloseableHttpClient httpClient = HttpClientFactory.createClient();
+		try {
+			CloseableHttpResponse response = httpClient.execute(patch);
+			assertEquals(200, response.getStatusLine().getStatusCode());
+		} finally {
+			httpClient.close();
+		}
+	}
+}
