Error in Test class of Apex Rest Callouts
Hi All,
Trying to solve the trailhead of "Apex REST Callouts". Copied the code of "Test a Callout with StaticResourceCalloutMock"
Apex Class Code follows:-
public class AnimalsCallouts {
public static HttpResponse makeGetCallout() {
Http http = new Http();
HttpRequest request = new HttpRequest();
request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals');
request.setMethod('GET');
HttpResponse response = http.send(request);
// If the request is successful, parse the JSON response.
if (response.getStatusCode() == 200) {
// Deserializes the JSON string into collections of primitive data types.
Map<String, Object> results = (Map<String, Object>) JSON.deserializeUntyped(response.getBody());
// Cast the values in the 'animals' key as a list
List<Object> animals = (List<Object>) results.get('animals');
System.debug('Received the following animals:');
for (Object animal: animals) {
System.debug(animal);
}
}
return response;
}
public static HttpResponse makePostCallout() {
Http http = new Http();
HttpRequest request = new HttpRequest();
request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals');
request.setMethod('POST');
request.setHeader('Content-Type', 'application/json;charset=UTF-8');
request.setBody('{"name":"mighty moose"}');
HttpResponse response = http.send(request);
// Parse the JSON response
if (response.getStatusCode() != 201) {
System.debug('The status code returned was not expected: ' +
response.getStatusCode() + ' ' + response.getStatus());
} else {
System.debug(response.getBody());
}
return response;
}
}
Static resource follows:-
{"animals": ["pesky porcupine", "hungry hippo", "squeaky squirrel"]}
Test Class follows:-
@isTest
private class AnimalsCalloutsTest {
@isTest static void testGetCallout() {
// Create the mock response based on a static resource
StaticResourceCalloutMock mock = new StaticResourceCalloutMock();
mock.setStaticResource('GetAnimalResource');
mock.setStatusCode(200);
mock.setHeader('Content-Type', 'application/json;charset=UTF-8');
// Associate the callout with a mock response
Test.setMock(HttpCalloutMock.class, mock);
// Call method to test
HttpResponse result = AnimalsCallouts.makeGetCallout();
// Verify mock response is not null
System.assertNotEquals(null,result,
'The callout returned a null response.');
// Verify status code
System.assertEquals(200,result.getStatusCode(),
'The status code is not 200.');
// Verify content type
System.assertEquals('application/json;charset=UTF-8',
result.getHeader('Content-Type'),
'The content type value is not expected.');
// Verify the array contains 3 items
Map<String, Object> results = (Map<String, Object>)
JSON.deserializeUntyped(result.getBody());
List<Object> animals = (List<Object>) results.get('animals');
System.assertEquals(3, animals.size(),
'The array should only contain 3 items.');
}
}
But while saving the code for test class it's throwing a compilation error, stating:-
"Method does not exist or incorrect signature: void setMock(System.Type, System.StaticResourceCalloutMock) from the type test"
Request you to guide me with this. Thanks in advance!

First we need to create HttpCalloutMock interface.
Please let me know you have already above class or not.
Thanks

Check have you created 'GetAnimalResource' with approriate JSON file.
If this answers your question mark Best Answer it as solution and then hit Like!
But according to the trailhead module "To test your callouts, use mock callouts by either implementing an interface or using static resources." So I have created a static resource instead of implementing an interface.
Thanks
Shovan
I have created the static resource 'GetAnimalResource' also. You can check the static resource in the code snippet as well.
Thanks,
Shovan
Can you please make sure, you don't have an apex class with the name 'Test' in your org. If you have, kindly delete that first and give your test class one more try.

I have deleted the test class and created another one without appending "test" in the class name, even though its not working.
