base on Java DSL for easy testing of REST services  [](https://github.com/rest-assured/rest-assured/actions/workflows/ci.yml) [](https://maven-badges.herokuapp.com/maven-central/io.rest-assured/rest-assured) <!-- [](http://www.javadoc.io/doc/io.rest-assured/rest-assured) --> 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. ## News * 2025-05-22: REST Assured 5.5.5 is released that fixes problems with `rest-assured-bom` file after moving to new deployment method. See [change log](https://raw.githubusercontent.com/rest-assured/rest-assured/master/changelog.txt) for more details. * 2025-05-22: REST Assured 5.5.3 is released with improved cookie handling when using [CSRF cookie propagation](https://github.com/rest-assured/rest-assured/wiki/Usage#csrf-cookie-propagation). See [change log](https://raw.githubusercontent.com/rest-assured/rest-assured/master/changelog.txt) for more details. * 2025-05-14: REST Assured 5.5.2 is released with bug fixes and minor improvements. See [change log](https://raw.githubusercontent.com/rest-assured/rest-assured/master/changelog.txt) for more details. [Older News](https://github.com/rest-assured/rest-assured/wiki/OldNews) ## Examples Here's an example of how to make a GET request and validate the JSON or XML response: ```java get("/lotto").then().assertThat().body("lotto.lottoId", equalTo(5)); ``` Get and verify all winner ids: ```java get("/lotto").then().assertThat().body("lotto.winners.winnerId", hasItems(23, 54)); ``` Using parameters: ```java given(). param("key1", "value1"). param("key2", "value2"). when(). post("/somewhere"). then(). body(containsString("OK")); ``` Using X-Path (XML only): ```java given(). params("firstName", "John", "lastName", "Doe"). when(). post("/greetMe"). then(). body(hasXPath("/greeting/firstName[text()='John']")). ``` Need authentication? REST Assured provides several authentication mechanisms: ```java given().auth().basic(username, password).when().get("/secured").then().statusCode(200); ``` Getting and parsing a response body: ```java // Example with JsonPath String json = get("/lotto").asString(); List<String> winnerIds = 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. ## Documentation * [Getting started](https://github.com/rest-assured/rest-assured/wiki/GettingStarted) * [Usage Guide](https://github.com/rest-assured/rest-assured/wiki/Usage) (click [here](https://github.com/rest-assured/rest-assured/wiki/Usage_Legacy) for legacy documentation) * [Javadoc](http://www.javadoc.io/doc/io.rest-assured/rest-assured/5.5.3) * [Rest Assured Javadoc](http://static.javadoc.io/io.rest-assured/rest-assured/5.5.5/io/restassured/RestAssured.html) * [Rest AssuredMockMvc Javadoc](http://static.javadoc.io/io.rest-assured/spring-mock-mvc/5.5.5/io/restassured/module/mockmvc/RestAssuredMockMvc.html) * [XmlPath Javadoc](http://static.javadoc.io/io.rest-assured/xml-path/5.5.5/io/restassured/path/xml/XmlPath.html) * [JsonPath Javadoc](http://static.javadoc.io/io.rest-assured/json-path/5.5.5/io/restassured/path/json/JsonPath.html) * [Release Notes](https://github.com/rest-assured/rest-assured/wiki/ReleaseNotes) * [FAQ](https://github.com/rest-assured/rest-assured/wiki/FAQ) ## Support and discussion Join the mailing list at our [Google group](http://groups.google.com/group/rest-assured). ## Links * [Change log](https://github.com/rest-assured/rest-assured/raw/master/changelog.txt) * REST Assured on [openhub](https://www.openhub.net/p/rest-assured) * [Mailing list](http://groups.google.com/group/rest-assured) for questions and support <a href="https://www.buymeacoffee.com/johanhaleby" target="_blank"><img src="https://cdn.buymeacoffee.com/buttons/arial-blue.png" alt="Buy Me A Coffee" style="height: 42px !important;width: 180px !important;" height="42px" width="180px"></a> ", Assign "at most 3 tags" to the expected json: {"id":"2499","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
