REST Assured is a Java library that provides a domain-specific language (DSL) for writing powerful, maintainable tests for RESTful APIs. REST Assured can be used easily in combination with testing frameworks such as JUnit and TestNG.

}Q 1. What is RequestSpecBuilder?
Q 2. What is difference between .body() and .content()?
get("http://localhost:3000/get_200_OK_SIMPLE_BODY_MESSAGE").then().body(...)
get("http://localhost:3000/get_200_OK_SIMPLE_BODY_MESSAGE").then().content(...)
Q 3. Write a use case where we use .log() function for verification using restassured. get("http://localhost:3000/get_200_OK_SIMPLE_BODY_MESSAGE").then().log()
Q 4. What is ResponseAwareMatcher? How do we use it?
Q 5. What is difference b/w below statements?
get("/something").then().assertThat().body(containsString("OK")).and().body(containsString("something else")); and get("/something").then().assertThat().body(containsString("OK")).body(containsString("something else"));
Q 6. Explore the usage of below
using()
statusLine()
appendRoot()
defaultParser()
detachRoot()
noRoot()
noRootPath()
parser()
spec()
specification()
Q 7. What is ResponseSpecBuilder?
Suppose that you have lot of API tests and all requier a header information. Instead of having to write this into the test each time, you can use RequestSpecBuilder.
public void test17() {
RequestSpecBuilder builder= new RequestSpecBuilder();
RequestSpecification requestSpec;
builder.addHeader("Content-Type","application/json");
builder.addParam("user","Kamal");
requestSpec = builder.build();
given().spec(requestSpec).when().post("http://localhost:3000/post_200_With_Header").then().body("lname",equalTo("girdher"));
}Again, if you have a number of API tests. It is quite reasonable to check the response code 200 of every call. Instead of having to write this into the test each time, you can use ResponseSpecBuilder.
public void test18() {
ResponseSpecBuilder builder= new ResponseSpecBuilder();
ResponseSpecification responseSpec;
builder.expectStatusCode(200);
builder.expectBody("fname",equalTo("kamal"));
responseSpec = builder.build();
given().post("http://localhost:3000/post_200_With_Header").then().spec(responseSpec);
}
