How to test Rest API which require authentication using Rest assured

Question

I want to test a Rest API which require authentication, before getting the Json response. FOr exa. If i want to visit rest API: http://192.168.xx.xx:9000/dashboards/all/list/m1/p1/sch1 then if I am not already logged in , then this will redirect me to Login HTML page, and after login, this will show me the Json output. Now I want to write a Rest assured code in java for same: I dont know , whether this is possible to do login using this or not. SO I written a simple code for same:: ``` public class TestNGSimpleTest1 { @Test public void testAdd() { //expect(). //statusCode(400). //body("Status", equalTo("Success")). //when(). //get("http://localhost:9000/dashboards/all/list/m1/p1/sch1"); //System.out.println("Response received is ::" +res); Response res = get("http://localhost:9000/dashboards/all/list/m1/p1/sch1"); assertEquals(200,res.getStatusCode()); String json = res.asString(); System.out.println("Response received is :: " +json); } ``` So here instead of getting the Json response…

Accepted Answer

If you are using default authentication from JIRA, then preemptive authentication is what you need. Below are the sample code.

```
RestAssured.baseURI = System.getProperty("baseurl");
PreemptiveBasicAuthScheme authScheme = new PreemptiveBasicAuthScheme();
authScheme.setUserName("admin");
authScheme.setPassword("admin");
RestAssured.authentication = authScheme;
```

The sample code will help you do the authentication before every request you send.
