Lambda

Prerequisite

Java 8 functionality

CodeSV also supports lambda expressions from Java 8. They can be quite easy and conventionally used as matchers or with matchers.

Basic lambda example:

  private static final String URL = "http://www.ca.com/portfolio?year=2016&tokenQuery=X4sPhj15WQE";

  @Rule
  public VirtualServerRule vs = new VirtualServerRule();


  @Test
  public void testLambda() throws Exception {
    forGet(URL)
        .matchesHeader("Custom-Header", s -> s.equals("CustomValue"))
        .doReturn(
            okMessage()
                .withJsonBody("Success"));

    HttpClient client = HttpClientBuilder.create().build();
    HttpGet request = new HttpGet(URL);
    request.addHeader("Custom-Header", "CustomValue");

    HttpResponse response = client.execute(request);

    BufferedReader reader = new BufferedReader(
        new InputStreamReader(response.getEntity().getContent()));
    StringBuffer result = new StringBuffer();
    String line;
    while ((line = reader.readLine()) != null) {
      result.append(line);
    }

    String body = result.toString();

    assertEquals(200, response.getStatusLine().getStatusCode());
    assertNotNull(body);
  }
