Testing and validation of REST services in Java is harder than in dynamic languages such as Ruby and Groovy. REST Assured brings the simplicity of using these languages into the Java domain.

Examples

Here's an example of how to make a GET request and validate the JSON or XML response:

get("/lotto").then().assertThat().body("lotto.lottoId", equalTo(5));

Get and verify all winner ids:

get("/lotto").then().assertThat().body("lotto.winners.winnerId", hasItems(23, 54));

Using parameters:

given().
    param("key1", "value1").
    param("key2", "value2").
when().
    post("/somewhere").
then().
    body(containsString("OK"));

Using X-Path (XML only):

given().
    params("firstName", "John", "lastName", "Doe").
when().
    post("/greetMe").
then().
    body(hasXPath("/greeting/firstName[text()='John']")).

Need authentication? REST Assured provides several authentication mechanisms:

given().auth().basic(username, password).when().get("/secured").then().statusCode(200);

Getting and parsing a response body:

// Example with JsonPath
String json = get("/lotto").asString()
List<String> winnderIds = from(json).get("lotto.winners.winnerId");
    
// Example with XmlPath
String xml = post("/shopping").andReturn().body().asString()
Node category = from(xml).get("shopping.category[0]");

REST Assured supports any HTTP method but has explicit support for POST, GET, PUT, DELETE, OPTIONS, PATCH and HEAD and includes specifying and validating e.g. parameters, headers, cookies and body easily.
