Unable to find specific subclass of NSManagedObject
... setting
creating instances works both in the main application and in unit tests.
The managed object subclass must not be marked with @objc(classname) (this was observed in https://stackoverflow.com/a/31288029/1187415).
Alternatively, you can empty the "Module" field (it will show "None") and mark ...
Right way to initialize an OrderedDict using its constructor such that it retains order of initial d
...ly maintains an order. Since a dict has an unpredictable order, what if my test vectors luckily has the same initial order as the unpredictable order of a dict?. For example, if instead of d = OrderedDict({'b':2, 'a':1}) I write d = OrderedDict({'a':1, 'b':2}), I can wrongly conclude that the order ...
How can I include raw JSON in an object using Jackson?

Any way to modify Jasmine spies based on arguments?
I have a function I'd like to test which calls an external API method twice, using different parameters. I'd like to mock this external API out with a Jasmine spy, and return different things based on the parameters. Is there any way to do this in Jasmine? The best I can come up with is a hack using...

It is both true that the first form:
function test() { }
is a more recognized syntax and that the second form:

If you are testing for properties that are on the object itself (not a part of its prototype chain) you can use .hasOwnProperty():
if (x.hasOwnProperty('y')) {
// ......
}
Object or its prototype has a property:
You can use the i...
Timer function to provide time in nano seconds using C++
... <chrono>. Additionally I'll demonstrate how you can templatize the testing code on the clock so that you can rapidly switch between RDTSC and your system's built-in clock facilities (which will likely be based on clock(), clock_gettime() and/or QueryPerformanceCounter.
Note that the RDTSC i...
In Java 8 how do I transform a Map to another Map using a lambda?
...
Map<String, Integer> map = new HashMap<>();
map.put("test1", 1);
map.put("test2", 2);
Map<String, Integer> map2 = new HashMap<>();
map.forEach(map2::put);
System.out.println("map: " + map);
System.out.println("map2: " + map2);
// Output:
// map: {test2=2, test1=1...
What is “:-!!” in C code?
...answer here has a good response:
These macros implement a compile-time test, while assert() is a run-time test.
Exactly right. You don't want to detect problems in your kernel at runtime that could have been caught earlier! It's a critical piece of the operating system. To whatever extent prob...
