我想爲我創建的簡單UIDevice類別設置一些測試用例。 因爲這些方法是實例方法,所以我創建了一個模擬來模擬currentDevice行爲。 添加的方法基於name屬性,所以我創建了一個存根以在name屬性上返回一個假名稱。OCMock類別
存根運作良好,但如果我嘗試訪問我的其他方法,我得到非嘲弄的名稱屬性。
這裏是我的測試案例:
#import "UIDevice_NameFromDevice_Tests.h"
#import <OCMock/OCMock.h>
#import "UIDevice+UnitTests.h"
#import "UIDevice+NameFromDevice.h"
@implementation UIDevice_NameFromDevice_Tests
-(void)setUp
{
self.firstName = @"John";
self.lastName = @"Doe";
self.fullName = [NSString stringWithFormat:@"%@ %@",self.firstName,self.lastName];
self.mockedDevice = [UIDevice createNicelyMockedCurrentDevice];
}
-(void)tearDown
{
self.firstName = nil;
self.lastName = nil;
self.fullName = nil;
[UIDevice releaseInstance];
}
#pragma mark UIDevice mock checks
-(void)test_mockedDevice_shouldBeEqualToCurrentDevice
{
self.mockedDevice = [UIDevice createMockedCurrentDevice];
STAssertEqualObjects(self.mockedDevice, [UIDevice currentDevice], nil);
}
-(void)test_stubedDeviceName_shouldBeEqualToCurrentDeviceName
{
NSString *format = @"%@ %@'s iPhone";
NSString *fakeiPhoneName = [NSString stringWithFormat:format,self.firstName,self.lastName];
[[[self.mockedDevice stub] andReturn:fakeiPhoneName] name];
STAssertEqualObjects([self.mockedDevice name], [[UIDevice currentDevice] name], nil);
STAssertEqualObjects([[UIDevice currentDevice] name], fakeiPhoneName, nil);
}
#pragma mark test langages
-(void)test_BasicENName_shouldReturnValues
{
NSString *fakeiPhoneName = [NSString stringWithFormat:@"%@'s iPhone", self.fullName];
[[[self.mockedDevice stub] andReturn:fakeiPhoneName] name];
NSLog(@"name : %@",[[UIDevice currentDevice] name]);
NSLog(@"fullname : %@",[[UIDevice currentDevice] fullNameFromDevice]);
NSLog(@"firstname : %@",[[UIDevice currentDevice] firstName]);
NSLog(@"lastname : %@",[[UIDevice currentDevice] lastName]);
STAssertEqualObjects([self.mockedDevice name], [[UIDevice currentDevice] name], nil);
STAssertEqualObjects([[UIDevice currentDevice] name], fakeiPhoneName, nil);
// STAssertEqualObjects([[UIDevice currentDevice] fullNameFromDevice], self.fullName, nil);
// STAssertEqualObjects([[UIDevice currentDevice] firstName], self.firstName, nil);
// STAssertEqualObjects([[UIDevice currentDevice] lastName], self.lastName, nil);
}

沒有任何人有什麼想法?
什麼是+ createNicelyMockedCurrentDevice和+ createMockedCurrentDevice?你可以發佈這些方法的代碼嗎? 我一直在嘲笑像[UIDevice currentDevice]這樣的單例對象,並且通常會將一個輔助方法放入我想要測試的類中,該方法返回生產代碼中的單例,然後使用部分模擬使其返回一個模擬對象單元測試。 – Greg
