I'm using RestKit ~> 0.20.3 and RestKit/Testing ~> 0.20.3. So this is an example of my mapping:
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[PlayerVO class]];
[mapping addAttributeMappingsFromArray:@[@"firstName", @"middeName", @"lastName", @"dob", @"sex"]];
This is my mock data:
NSDictionary *data = @{@"players": @[@{@"firstName": @"Ahmed", @"middleName": @"Ahmed", @"lastName": @"Ahmed", @"dob": @"100", @"sex": @"m"}]};
This is my mappingTest
:
RKMappingTest *mappingTest = [RKMappingTest testForMapping:mapping sourceObject:data destinationObject:nil];
And finally my expectation
:
RKPropertyMappingTestExpectation *expectation = [RKPropertyMappingTestExpectation expectationWithSourceKeyPath:@"players.firstName" destinationKeyPath:@"firstName" evaluationBlock:^BOOL(RKPropertyMappingTestExpectation *expectation, RKPropertyMapping *mapping, id mappedValue, NSError *__autoreleasing *error) {
BOOL expect = [mappedValue length] > 0;
XCTAssertTrue(expect);
return expect;
}];
[mappingTest addExpectation:expectation];
XCTAssertTrue([mappingTest evaluate]);
XCTAssertNoThrow([mappingTest verify]);
So this test fails as there doesn't seem to be a way I can specify a key path to follow as the data
is an array. This is the error I get:
testPlayerServiceGetPlayers] : (([mappingTest verify]) does not throw) failed: throwing "0x8e7d770: failed with error: (null)
RKMappingTest Expectations: (
"map 'players.firstName' to 'firstName' satisfying evaluation block"
)
Events: (
) during mapping from {
players = (
{
dob = 100;
firstName = Ahmed;
lastName = Ahmed;
middleName = Ahmed;
sex = m;
}
);
} to (null) with mapping <RKObjectMapping:0x8e6aad0 objectClass=PlayerVO propertyMappings=(
"<RKAttributeMapping: 0x8e6b880 firstName => firstName>",
"<RKAttributeMapping: 0x8e61df0 middeName => middeName>",
"<RKAttributeMapping: 0x8e2f580 lastName => lastName>",
"<RKAttributeMapping: 0x8e67a60 dob => dob>",
"<RKAttributeMapping: 0x8e2c120 sex => sex>"
)>"
If I change my data to:
NSDictionary *data = @{@"firstName": @"Ahmed", @"middleName": @"Naseer", @"lastName": @"Nuaman", @"dob": @"524534400", @"sex": @"m"};
And the expectation
's expectationWithSourceKeyPath
to @"firstName"
, the tests pass. So this leads me to believe the issue is clearly relative to setting the key path. Now in my app that's done using:
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping method:RKRequestMethodAny pathPattern:nil keyPath:@"players" statusCodes:statusCodes];
However I can't find a way of setting the keyPath
for a RKMappingTest
or RKPropertyMappingTestExpectation
, any ideas on how I can achieve this?
Update
So I had a look throughRKMappingTest.h
and found the rootKeyPath
. I set the following:
mappingTest.rootKeyPath = @"players";
And still was having problems regarding the mappedValue
in the RKPropertyMappingTestExpectation
. So I also changed my data to this:
NSDictionary *data = @{@"players": @{@"firstName": @"Ahmed", @"middleName": @"Ahmed", @"lastName": @"Ahmed", @"dob": @"100", @"sex": @"m"}};
And now I can see that mappedValue
is now set to Ahmed
and updated the RKPropertyMappingTestExpectation
to the following:
RKPropertyMappingTestExpectation *expectation = [RKPropertyMappingTestExpectation expectationWithSourceKeyPath:@"firstName" destinationKeyPath:@"firstName" evaluationBlock:^BOOL(RKPropertyMappingTestExpectation *expectation, RKPropertyMapping *mapping, id mappedValue, NSError *__autoreleasing *error) {
return [mappedValue isEqualToString:@"Ahmed"];
}];
But this is using an object rather than an array. Any more suggestions?
You're thinking about testing, and more specifically the scope of testing, wrongly. This is a unit test, and the unit is the mapping. The mapping deals with individual items and that is why your modified test works - because the scope is correct.
Response descriptors have a different scope. You can't test the scope of a response descriptor in a mapping test.
