Class RestResponse

java.lang.Object

com.jcabi.http.response.RestResponse

All Implemented Interfaces:

Response

@Immutable
public final class RestResponse
extends Object

REST response.

This response decorator is able to make basic assertions on HTTP response and manipulate with it afterwords, for example:

 String name = new JdkRequest("http://my.example.com")
   .fetch()
   .as(RestResponse.class)
   .assertStatus(200)
   .assertBody(Matchers.containsString("hello, world!"))
   .assertHeader("Content-Type", Matchers.hasItem("text/plain"))
   .jump(URI.create("/users"))
   .fetch();

Method jump(URI) creates a new instance of class Request with all cookies transferred from the current one.

The class is immutable and thread-safe.

Constructor Detail

RestResponse

public RestResponse(@NotNull(message="response can\'t be NULL")
            Response resp)

Public ctor.

Parameters:

resp - Response

Method Detail

assertThat

@NotNull(message="new response is never NULL")
public RestResponse assertThat(@NotNull(message="matcher can\'t be NULL")
                              org.hamcrest.Matcher<Response> matcher)

Assert using custom matcher.

Parameters:

matcher - The matcher to use

Returns:

The same object

assertStatus

@NotNull(message="response is never NULL")
public RestResponse assertStatus(int status)

Verifies HTTP response status code against the provided absolute value, and throws AssertionError in case of mismatch.

Parameters:

status - Expected status code

Returns:

The same object

assertStatus

@NotNull(message="REST response is never NULL")
public RestResponse assertStatus(@NotNull(message="status matcher can\'t be NULL")
                                org.hamcrest.Matcher<Integer> matcher)

Verifies HTTP response status code against the provided matcher, and throws AssertionError in case of mismatch.

Parameters:

matcher - Matcher to validate status code

Returns:

This object

assertBody

@NotNull(message="REST response is never NULL")
public RestResponse assertBody(@NotNull(message="body matcher can\'t be NULL")
                              org.hamcrest.Matcher<String> matcher)

Verifies HTTP response body content against provided matcher, and throws AssertionError in case of mismatch.

Parameters:

matcher - The matcher to use

Returns:

This object

assertHeader

@NotNull(message="response is never NULL")
public RestResponse assertHeader(@NotNull(message="header name can\'t be NULL")
                                String name,
                                @NotNull(message="header matcher can\'t be NULL")
                                org.hamcrest.Matcher<Iterable<String>> matcher)

Verifies HTTP header against provided matcher, and throws AssertionError in case of mismatch.

The iterator for the matcher will always be a real object an never NULL, even if such a header is absent in the response. If the header is absent the iterable will be empty.

Parameters:

name - Name of the header to match

matcher - The matcher to use

Returns:

This object

assertHeader

@NotNull(message="response is never NULL")
public RestResponse assertHeader(@NotNull(message="header name can\'t be NULL")
                                String name,
                                @NotNull(message="header value can\'t be NULL")
                                String value)

Verifies HTTP header against provided matcher, and throws AssertionError in case of mismatch.

Parameters:

name - Name of the header to match

value - The value to expect in one of the headers

Returns:

This object
