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")
        .havingPathEqualTo("/accounts/1")
        .havingBody(isEmptyOrNullString())
        .havingHeaderEqualTo("Accept", "application/json")
    .respond()
        .withDelay(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();
}
