How to Use Groovy with a Custom Java HTTP Testing Framework

While developing a Java framework for HTTP interface testing, the author found that using a scripting language simplifies test case execution and management, and chose Groovy based on a recommendation.

The approach is to build the Java framework into a JAR file, then import that JAR in a Groovy script and directly call the framework’s methods to send HTTP requests and handle responses.

Below is the complete Groovy script used for the demonstration:

import net.sf.json.JSONObject
import org.apache.http.client.methods.HttpGet
import source.FanLibrary

class one extends FanLibrary {
    static void main(String[] args) {
        def httpGet = new HttpGet("http://cost-api.fissionpie.com/cost?_t=200&_app=1&_v=1.0.0&token=601_200_1524035146010_d78096e246592dfa&userId=56&type=1&maxId=0&length=10")
        def response = getHttpResponseEntityByJson(httpGet)
        println response
    }
}

The script creates an HttpGet object with the target URL, invokes the framework’s getHttpResponseEntityByJson method to obtain the JSON response, and prints the result to the console.

Running the script produces the following response (illustrated in the image):
