Highlights

  • Fixed misunderstanding of how GPath expressions works with XML and namespaces (see non-backward compatible changes)

  • It's now possible to use a mapping function when validating headers. For example let's say you want to validate that the Content-Length header is less than 1000. You can then use a mapping function to first convert the header value to an int and then use an "integer" Hamcrest matcher:

    when().get("/something").then().header("Content-Length", Integer::parseInt, lessThan(1000));

    This is also implemented for the MockMvc module (issue 594).

  • Added new config called ParamConfig that allows you to configure how parameter types should be updated on "collision". By default all parameters are merged so if you do:

    given().queryParam("param1", "value1").queryParam("param1", "value2").when().get("/x"). ...

    REST Assured will send a query string of param1=value1&param1=value2. This is not always what you want though so from now on you can configure REST Assured to replace values instead:

    given().
        config(config().paramConfig(paramConfig().queryParamsUpdateStrategy(REPLACE))).
        queryParam("param1", "value1").
        queryParam("param1", "value2").
when().
        get("/x"). ..

    REST Assured will now replace param1 with value2 (since it's written last) instead of merging them together. You can configure the update strategy for each type of for all parameter types:

    given().config(config().paramConfig(paramConfig().replaceAllParameters())). ..

    This is also implemented for the MockMvc module (but the config there is called MockMvcParamConfig (issue 589)

  • Added a new module called scala-support that adds an alias to the "then" method in Response or MockMvcResponse called "Then". The reason for this is that then might be a reserved keyword in Scala in the future and the compiler gives a warning when using methods with this name. To enable the use of Then simply import the com.jayway.restassured.module.scala.RestAssuredSupport.AddThenToResponse class from scala-support module. For example:

    import com.jayway.restassured.RestAssured.when
import com.jayway.restassured.module.scala.RestAssuredSupport.AddThenToResponse
import org.hamcrest.Matchers.equalTo
import org.junit.Test

@Test
def `trying out rest assured in scala with implicit conversion`() {
    when().
            get("/greetJSON").
    Then().
            statusCode(200).
            body("key", equalTo("value"))
}

    This is also support for the spring-mock-mvc module.

Other Notable Changes

  • Improvements to multipart uploading, for example:

    • Added support for setting multipart filename when passing in an object to multiPart method (issue 587)

    • Multipart file-uploading now takes encoder config into account when serializing content. For example if you're trying to serialize an object using mime-type "application/vnd.ms-excel" in a multipart then you can register that it should be serialize as JSON:

      Greeting greeting = new Greeting();
greeting.setFirstName("John");
greeting.setLastName("Doe");

given().
       config(config().encoderConfig(encoderConfig().encodeContentTypeAs("application/vnd.ms-excel", ContentType.JSON))).
       multiPart(new MultiPartSpecBuilder(greeting)
               .fileName("RoleBasedAccessFeaturePlan.csv")
               .controlName("text")
               .mimeType("application/vnd.ms-excel").build()).
when().
       post("/multipart/text").
then().
       statusCode(200);

      This will now serialize the "greeting" as JSON even though the mime-type is set to "application/vnd.ms-excel" (which is unknown to REST Assured) (issue 586)

    • You can now pass in which ObjectMapperType or ObjectMapper to use when serializing an object using multipart. For example:

      Greeting greeting = new Greeting();
greeting.setFirstName("John");
greeting.setLastName("Doe");

given().
       multiPart(new MultiPartSpecBuilder(greeting, ObjectMapperType.GSON)
                 .fileName("RoleBasedAccessFeaturePlan.csv")
                 .controlName("text")
                 .mimeType("application/vnd.ms-excel").build()).
when().
       post("/multipart/text").
then().
       statusCode(200);

      This will force the use if the GSON ObjectMapper (if available in the classpath) even though mime type is not recognized by default by REST Assured.

    • Content-Type for multipart requests is now taken into account. For example you can now do:

      given().contentType("multipart/mixed").multiPart(..)

      which was not possible in the previous version. (Only "multipart/form-data" worked) (issue 586)

    • It's now possible to specify default mime subtype for multipart content-type. Use the MultiPartConfig#defaultSubtype(..) method. Default is "form-data" which results in a content-type of "multipart/form-data". This also works for the MockMvc module.

  • Added ability to specify which encoder charset to use for a specific content-type if no charset is defined explicitly for this content-type. Previously you could only specify a default charset for ALL content-types. You do this by using the defaultCharsetForContentType method in the EncoderConfig. For example:

    RestAssured.config = config(config().encoderConfig(encoderConfig().defaultCharsetForContentType("UTF-16", "application/xml")));

    This will assume UTF-16 encoding for "application/xml" content-types that does explicitly specify a charset. By default "application/json" is now specified to use "UTF-8" as default content-type as this is specified by RFC4627. This is may be a backward incompatible change since previously "application/json" content-types were encoded using the platform default content-type (or what was specified by defaultContentCharset(..)) (issue 567).

  • Added ability to specify which decoder charset to use for a specific content-type if no charset is defined explicitly for this content-type. Previously you could only specify a default charset for ALL content-types. You do this by using the "defaultCharsetForContentType" method in the DecoderConfig. For example:

    RestAssured.config = config(config().decoderConfig(decoderConfig().defaultCharsetForContentType("UTF-16", "application/xml")));

    This will assume UTF-16 encoding for "application/xml" content-types that does explicitly specify a charset. By default "application/json" is now specified to use "UTF-8" as default charset as this is specified by RFC4627. This is may be a backward incompatible change since previously "application/json" content-types were encoded using the platform default content-type (or what was specified by defaultContentCharset(..)).

Non-backward compatible changes

  • Fixed so that GPath expressions using XML namespaces are evaluated from the root. The implementation was previously a misunderstanding of how the Groovy's XmlSlurper worked when using namespace and has now been corrected. For example let's say have a service at /namespace-example that returns the following XML:

    <foo xmlns:ns="http://localhost/">
  <bar>sudo </bar>
  <ns:bar>make me a sandwich!</ns:bar>
</foo>

    You NOW test it like this:

    given().
        config(newConfig().xmlConfig(xmlConfig().declareNamespace("ns", "http://localhost/"))).
when().
        get("/namespace-example").
then().
        body("foo.bar.text()", equalTo("sudo make me a sandwich!")).
        body(":foo.:bar.text()", equalTo("sudo ")).
        body("foo.ns:bar.text()", equalTo("make me a sandwich!"));

    In the previous versions you did like this:

    given().
        config(newConfig().xmlConfig(xmlConfig().declareNamespace("ns", "http://localhost/"))).
when().
        get("/namespace-example").
then().
        body("bar.text()", equalTo("sudo make me a sandwich!")).
        body(":bar.text()", equalTo("sudo ")).
        body("ns:bar.text()", equalTo("make me a sandwich!"));

    Which was not correct (notice the missing foo property)! Big thanks to Erich Eichinger for spotting this and providing a pull request (issue 592).

  • When multiple cookies or headers with the same name are returned in the response the LAST value is what's returned when only getting one value from the entity (Headers or Cookies) or when validating values. For example let's say that the server returns headers:

    HeaderName: Value 1
HeaderName: Value 2

    then if you do:

    get("/x").extract().header("HeaderName")

    Value 2 will be returned (previously Value 1 would be returned). Likewise if you do validation:

    get("/x").then().header("HeaderName", equalTo("Value 2"));

    This change also affects session ids. This is done to be compatible with the way browsers work (issue 543).

  • The last (instead of first) header, cookie, session etc is returned when calling for example headers.get("x") and multiple headers are defined (see defaultCharsetForContentType section under other notable changes for more details)
