Build Status

Welcome to Jadler, Java http mocking library.

If you need a simple way to create a stub http server in your integration tests and do some http communication mocking, look no further! Writing tests for http client applications can be as easy as:

@Test
public void getAccount() {

    onRequest()
        .havingMethodEqualTo("GET")
        .havingURIEqualTo("/accounts/1")
        .havingBody(isEmptyOrNullString())
        .havingHeaderEqualTo("Accept", "application/json")
    .respond()
        .withTimeout(2, SECONDS)
        .withStatus(200)
        .withBody("{\\"account\\":{\\"id\\" : 1}}")
        .withEncoding(Charset.forName("UTF-8"))
        .withContentType("application/json; charset=UTF-8");

    final AccountService service = new AccountServiceRestImpl("http", "localhost", port());
    final Account account = service.getAccount(1);

    assertThat(account, is(notNullValue()));
    assertThat(account.getId(), is(1));
}


@Test
public void deleteAccount() {

    onRequest()
        .havingMethodEqualTo("DELETE")
        .havingPathEqualTo("/accounts/1")
    .respond()
        .withStatus(204);

    final AccountService service = new AccountServiceRestImpl("http", "localhost", port());
    service.deleteAccount(1);

    verifyThatRequest()
        .havingMethodEqualTo("DELETE")
        .havingPathEqualTo("/accounts/1")
    .receivedOnce();
}

@Test
public void getFile() throws IOException{
    initJadlerListeningOn(8081).that().respondsWithDefaultStatus(200);
    String fileService = "http://localhost:8081/getExcelFile";

    byte[] bytes = IOUtils.toByteArray(new FileInputStream(myExcelFile));

    onRequest()
        .havingPathEqualTo("/getExcelFile")
    .respond()
        .withBody(bytes)
    .withContentType("applicatoin/vnd.ms-excel")
    .withHeader("Content-Length", Integer.toString(bytes.length));

    HttpClient client = new HttpClient(new MultiThreadedHttpConnectionManager());
    GetMethod get = new GetMethod(new URL(fileService).toExternalForm());
    int responseCode = client.executeMethod(get);

    assertEquals(200, responseCode);
    assertEquals(bytes.length, get.getResponseBodyAsString().getBytes().length);
}
