Accessing secured APIs using RestAssured

Accessing secured APIs

Basic Authentication (i.e., the consumer of this API needs to provide a valid username and password combination every time they call the API)

@Test
public void test_APIWithBasicAuthentication() {
   
    given().
        auth().
        preemptive().
        basic("username", "password").
    when().
        get("http://path.to/basic/secured/api").
    then().
        assertThat().
        statusCode(200);
}

Accessing an OAuth2-secured API 

@Test
public void test_APIWithOAuth2Authentication() {
   
    given().
        auth().
        oauth2(YOUR_AUTHENTICATION_TOKEN_GOES_HERE).
    when().
        get("http://path.to/oath2/secured/api").
    then().
        assertThat().
        statusCode(200);

}

Passing parameters between tests

@Test
public void test_ScenarioRetrieveFirstCircuitFor2017SeasonAndGetCountry_ShouldBeAustralia() {
   
    // First, retrieve the circuit ID for the first circuit of the 2017 season
    String circuitId = given().
    when().
        get("http://ergast.com/api/f1/2017/circuits.json").
    then().
        extract().
        path("MRData.CircuitTable.Circuits.circuitId[0]");
   
    // Then, retrieve the information known for that circuit and verify it is located in Australia
    given().
        pathParam("circuitId",circuitId).
    when().
        get("http://ergast.com/api/f1/circuits/{circuitId}.json").
    then().
        assertThat().
        body("MRData.CircuitTable.Circuits.Location[0].country",equalTo("Australia"));
