RestAssured API Framework

Rest Assured-- core features

--jdk gives httpclient, so we can call

using httpclient

wrappers libraies aviable on top of httpclient

---Rest assured

OKHttpClient

JerseyClient

-----------------------------------

Request 

-Method - get,put,post,delete

-URL - baseURL + /endpoint + query params

-HEADER :

-Request Body/PayLoad

-Auth :Oauth1 , Oauth2, JWT, BearerToken,APIKEY,Basic Auth

Response

- status

-status line

- body: jsonpath,xmlpath()

-Headers

-Cookies

open suce

java dsl

MAVEN

-maven-archetype-quick

-restAssured LIB :pom.xml

TESTNG: unit test framework

** api runs in sequal mode no parral like UI

***************************

BDD Style - approach/methodology 

given, when , then 

NON -BDD Approach

RestAssured--is builder patterm and method chaining

given().log().all().then().get().when().assertThat().statuscode(200);

Hamcrest Library->RestAssured have Matchers library 

https://documenter.getpostman.com/view/4012288/TzK2bEa8#intro

08608080288

immutable map it means it cant be changed/updated

Map.of("name","Sudheer","age","30")

Response coming in a form of JSON Object

JSONPATH- get a JSONPATH view of the response body.

fetch whole json and get the value ,store it or assert .

equalTo- in json object{}

hasItem-Json array[]

pojo- plain old java object.

1-help me create a java object for the class

2-private data vaiblables.-- public getters/setters-encapsulation

3-public constructor

serialization- convert pojo to json

ObjectMapper(Jackson libirary)--add to pom.xml

de-serialization- convert json to pojo

Http : GET
