I'm following the Apex Rest Callouts trail which instructs you to write a unit test for a sample class.
All code is given, you just need to add it into their ide.
The problem is, one line from the trail's code errors and I have no prior Apex knowledge, so I'm kind of lost.
The class in question is:
@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.');
}
}
The error is in line 10 and says Method does not exist or incorrect signature: void setMock(System.Type, System.StaticResourceCalloutMock) from the type Test
The IDE is pretty rudimentary so it's difficult to see what type each expression has, but it seems the signature is incorrect (the method exists).
I'm not sure what it expects and following the trail further leads to the same error later on.
