## Chapter 1
2+
3+
#### Prerequisites
4+
* Basic Understanding of REST API's & CRUD Operations
5+
* Having a basic knowledge on RESTAssured Library, if not
6+
click [here](http://rest-assured.io/)
7+
8+
This Chapter consists three tests
9+
1. **Test-1:** Send a GET Request of an API and validate the body
10+
2. **Test-2:** Send a GET Request of an API and retrieve the data from body
11+
3. **Test-3:** Send a GET Request of an API and store the Response
12+
13+
#### Getting Started
14+
First let us quickly understand the following things
15+
1. **What is DSL?**
16+
2. **Keywords present in RESTAssured DSL**
17+
18+
````What is DSL?````
19+
20+
Domain Specific Language (DSL) DSLs are small languages, focused on a particular
21+
aspect of a software system. You can't build a whole program with a DSL,
22+
but you often use multiple DSLs in a system mainly written in a general purpose language.
23+
24+
````Keywords present in RESTAssured DSL````
25+
1. given()
26+
2. when()
27+
3. body()
28+
4. extract()
29+
30+
And other <b>Keywords</b> are used following to the `given|when|then|extract`. Click [here](https://github.com/rest-assured/rest-assured/wiki/usage)
31+
to check the few more keywords.
32+
#### Sequence of creating a Request and receiving a Response
33+
1. `given()` - These are the configs that we can define following to the current keyword
34+
* QueryParameters
35+
* Body
36+
* Headers
37+
2. `when()` - These are the following actions that can be implemented after this keyword
38+
* HTTP Method ( GET, POST, PUT, DELETE....)
39+
3. `then()` - Validations/Assertions need to be implemented after this keyword
40+
4. `extract()` - To retrieve a single value from JSON
41+
42+
![](https://i.imgur.com/8QMTKCY.png)
43+
44+
#### **Test-1:** Send a GET Request of an API and validate the body
45+
In this test we are going to Send a Request and Validate the JSON body
46+
1. `queryParam()` - Filter the Data with a given values
47+
2. `get()` - HTTP Method
48+
3. `statusCode()` - Response StatusCode
49+
4. `body()` - To get the data from the JSON and verify it.
50+
51+
#### **Test-2:** Send a GET Request of an API and retrieve the data from body
52+
In this test we are going to Send a Request and retrieve some data from the Response
53+
1. `extract()` - It is used to return any value from the JSON
54+
55+
#### **Test-3:** Send a GET Request of an API and store the Response
56+
Previously we have seen how to retrieve a single value. Now in this test we are going to store entire Response
57+
1. `Response response = given()...` - This way we can store the Response
58+
2. `response.getStatusCode` - Will return the StatusCode
59+
3. `response.getBody().asString()` - Returns entire JSON Body in a String format
60+
61+
#### Summary
62+
In this Chapter we have learnt about
63+
1. How to create and send a Request for GET API
64+
2. How to retrieve single data from JSON body
65+
3. How to Store the Response
