Testing Tutorial

Introduction

This is a quick tutorial on writing TestCases using REST Client 3.x.

Details

REST Client has Groovy embedded. Groovy supports JUnit 3.x type test cases (if you don't know what it means, just chill, because I will be explaining this shortly).

Writing Test Class

public class MyTest extends org.wiztools.restclient.RESTTestCase{

 /* TEST METHODS */

}

A Sample Test Method

All test methods should be named with prefix test. A sample test method which tests if the response body contains the text WizTools.org:

public void testRequestContainsWizTools(){
  if(response.getResponseBody() != null
      && (new String(response.getResponseBody(), "UTF-8").indexOf("WizTools.org") > -1)){
    // do nothing!
  }
  else{
    fail("Response body does not have `WizTools.org' text.");
  }
}

Two instance variables request and response with prepopulated data is available for the test script. The methods that can be invoked on these objects are detailed here: TestClass.

After making the request, the Response Test Result tab will show the result of executing the Test Script. Change the text WizTools.org to ABC2XYZ. Now place the request again, this would fail the test, and be reported in the Response Test Result tab.

The sample request is available here: [http://rest-client.googlecode.com/files/sample-test-request-30.rcq]. Download this and save to your local drive. Then open this file using File>Open Request in RESTClient interface.
