我有使用依赖对象(Keys对象)测试的类方法
APIRouter.m
+ (NSURL*)apiURLWithPath:(NSString*)path {
MyKeys *keys = [MyKeys new];
NSString *url = [NSString stringWithFormat:@"%@?api_key=%@", path, [keys APIKey]];
return [NSURL URLWithString:url];
}
我试图部分模拟这个Keys对象并返回“MY_API_KEY”值,但测试方法失败并返回真正的API密钥(例如as78d687as6d7das8da)。
APIRouterSpec.m
describe(@"APIRouter", ^{
it(@"should return url for api", ^{
Keys *keys = [Keys new];
id keysPartialMock = OCMPartialMock(keys);
OCMStub([keysPartialMock APIKey]).andReturn(@"MY_API_KEY");
NSURL *url = [APIRouter apiURLWithPath:@"http://www.api.com/v1/events"];
expect([url absoluteString]).to.equal([NSString stringWithFormat:@"http://www.api.com/v1/events?api_key=MY_API_KEY"]);
});
});
答案 0 :(得分:2)
也许这对你有用:
在测试方法之外的某处:
static NSString *gMockApiKey = @"MY_API_KEY";
将这样的方法存根:
OCMStub([keysPartialMock APIKey]).andDo(^(NSInvocation *invocation)
{
[invocation setReturnValue:&gMockApiKey];
});

由于APIRouter可能正在使用自己的Keys实例,因此您可以尝试使用类模拟:
id keysMock = OCMClassMock([Keys class]);
OCMStub(ClassMethod([keysMock APIKey])).andDo(^(NSInvocation *invocation)
{
[invocation setReturnValue:&gMockApiKey];
});

所以..我认为模拟它的正确方法是创建一个Keys的模拟实例。
位于测试文件顶部的某处:
static Keys *gMockedKeys = nil;
static NSString *gMockApiKey = @"MY_API_KEY";
设定:
- (void)setUp {
[super setUp];
gMockedKeys = [Keys new];
id keysPartialMock = OCMPartialMock(gMockedKeys);
OCMStub([keysPartialMock APIKey]).andDo(^(NSInvocation *invocation)
{
[invocation setReturnValue:&gMockApiKey];
});
}
试验:
- (void)testAPIURLWithPath {
id keysMock = OCMClassMock([Keys class]);
OCMStub([keysMock new]).andReturn(gMockedKeys);
NSURL *url = [APIRouter apiURLWithPath:@"http://www.api.com/v1/events"];
NSString *expectedUrlString = [url absoluteString];
XCTAssertEqualObjects(expectedUrlString, @"http://www.api.com/v1/events?api_key=MY_API_KEY", @"It Should work now..");
}
