 +====== 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();​
 + }
 + }
 +}
 +</​code>​
