Apex Integration Services "Apex SOAP Callouts"

Generate an Apex class using WSDL2Apex and write a test class.

Generate an Apex class using WSDL2Apex for a SOAP web service, write unit tests that achieve 100% code coverage for the class using a mock response, and run your Apex tests.

• Use WSDL2Apex to generate a class called 'ParkService' in public scope using this WSDL file. After you click the 'Parse WSDL' button don't forget to change the name of the Apex Class Name from 'parksServices' to 'ParkService'.
• Create a class called 'ParkLocator' that has a 'country' method that uses the 'ParkService' class and returns an array of available park names for a particular country passed to the web service. Possible country names that can be passed to the web service include Germany, India, Japan and United States.
• Create a test class named ParkLocatorTest that uses a mock class called ParkServiceMock to mock the callout response.
• The unit tests must cover all lines of code included in the ParkLocator class, resulting in 100% code coverage.
• Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.

ParkLocator Class:

public class ParkLocator { public static String[] country(String country){ ParkService.ParksImplPort Locator = new ParkService.ParksImplPort(); return Locator.byCountry(country); } }

ParkServiceMock class:

@isTest global class ParkServiceMock implements WebServiceMock{ global void doInvoke( Object stub, Object request, Map<String,Object> response, String endpoint, String soapAction, String requestName, String responseNS, String responseName, String responseType) { ParkService.byCountryResponse response_x = new ParkService.byCountryResponse(); response_x.return_x = new List<String>{'Garner State Park', 'Fowler Park', 'Hoosier National Forest Park'}; response.put('response_x',response_x); } }

ParkLocatorTest class:

@isTest private class ParkLocatorTest { testMethod static void testCallout(){ Test.setMock(WebServiceMock.class, new ParkServiceMock()); String country = 'United States'; String[] result = ParkLocator.country(country); System.assertEquals(new List<String>{'Garner State Park', 'Fowler Park', 'Hoosier National Forest Park'}, result); } }
