我试图写一个JSON验证单元测试(因为应用程序在很大程度上依赖于JSON从静止API)。
我有一个包含简单的JSON本地文件:“goodFeaturedJson.txt”
内容:
{
"test": "TEST"
}
测试案例:
- (void)testJsonIsValid
{
Featured *featured = [Featured new];
NSString* filepath = [[NSBundle mainBundle]pathForResource:@"goodFeaturedJson" ofType:@"text"];
NSData *data = [NSData dataWithContentsOfFile:filepath];
NSString *jsonString = [[NSString alloc] initWithContentsOfFile:filepath encoding:NSUTF8StringEncoding error:nil];//[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"The json string is: %@", jsonString);
id JSON = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
STAssertTrue([featured jsonIsValid:JSON], @"Featured Data is NOT valid...");
}
测试失败每次。 控制台打印:
The json string is: (null)
为什么? 我知道为什么测试失败,因为很明显,如果数据是零/零不会有有效的JSON,并验证将打破(这是它应该如果无效)。
必须有简单的东西我错过了这里,任何想法?
在单元测试中,你可能想使用[NSBundle bundleForClass:[self class]]
,而不是[NSBundle mainBundle]
这是因为单元测试是不是一个独立的应用程序。 随着mainBundle
你喜欢的东西/Applications/Xcode.app/Contents/Developer/Tools
,但使用bundleForClass
让你在您的单元测试类所在的包。
guard let pathString = Bundle(for: type(of: self)).path(forResource: "UnitTestData", ofType: "json") else {
fatalError("UnitTestData.json not found")
}
