Let's learn about PUT, POST and PATCH.

PUT, PATCH, and POST are HTTP methods used to interact with a REST API.

PUT:
It is used to update a resource completely. It requires the client to send the complete resource representation. Example: Updating a user's profile information.

PATCH:
It is used to partially update a resource. It requires the client to send only the changes. Example: Updating a user's password.

POST:
It is used to create a new resource. It requires the client to send the representation of the resources to be created. Example: Creating a new user account.

Note:
For RESTful APIs, PUT method should only be used if the client can update the entire resource, while PATCH can be used if the client can update only a part of the resource.
The POST method should be used to create a new resource.

- First option: By using the entire JSON in an external file

- Second way: Using POJO class

First way: By using the entire JSON in an external file

1. IOUtils class will provide a method toString()

2. tostring will take two input param: Inputstream, encoding type

3. Fileinputstream will take param as File

4. File will require input param as the path where we kept .json file

@Test(description= "Automate post method for users")

public static void postmethodjson() throws IOException {

FileInputStream file = new FileInputStream(new File (System.getProperty("user.dir")+"\\Resources\\TestData\\testdata.json"));

Response resp = given().header("Content-Type","application/json").

body(IOUtils.toString(file, "UTF-8")).

when().post("https://reqres.in/api/users");

assertEquals(resp.getStatusCode(),201);

System.out.println("The status code for post method is : " + resp.getStatusCode() );

System.out.println("The response body of the post method is : " + resp.getBody().asString());

assertEquals(resp.path("job"),"leader");

}

Second way: Using pojo class

How to create POJO class

How to automate with pojo class?

@Test

public static void postmethodwithpojoclass() {

String job = "tester";

String name = "automation";

pojoClass obj = new pojoClass(name,job);

Response resp = given().header("Content-Type","application/json").

body(obj).

when().post("https://reqres.in/api/users");

assertEquals(resp.getStatusCode(),201);

System.out.println("The status code for post method is : " + resp.getStatusCode() );

System.out.println("The response body of the post method is : " + resp.getBody().asString());

assertEquals(resp.path("job"),job);

assertEquals(resp.path("name"),name);

}

=========PATCH WITH POJO=======

@Test(groups="RegressionSuite")

pojoClass pjc = new pojoClass("morpheus", jobname);

Response resp = given().header("Content-Type","application/json").

// body(requestParams.toString()).

body(pjc).

when().

patch("https://reqres.in/api/users/2");

System.out.println(resp.getBody().asString());

assertEquals(resp.path("job"),jobname);

}
