Git did not invent these things.

What they need is something like VB but that uses python instead of basic. A Visual Python that runs on linux would be rad :D
@ormaaj. According ... By: purplemutantas. on 26 Jan 10, 22:31:02 @ormaaj. According to wikipedia android doesn't support the full set of standard GNU libraries. Nor does it use the x window system. Keep in mind that Linux was not originally intended to run with GNU. So there is no reason why you would absolutely have to use any part of GNU in order to use the linux kernel.
As far as my comment on Hurd. I know I am not running hurd. But once Debian GNU/Hurd is stable enough I might give it a try.
@purplemutantas ... By: Ormaaj. on 26 Jan 10, 19:38:01 @purplemutantas Really? I would bet even android would have to use glibc and coreutils if its running on linux. You can't really break free from that very easily. Sometimes embedded things can get away with uclibc and busybox but theres still probably something gnu in there.
Hurd is basically unused. There are a few very experimental things like Debian which use hurd, but for practical purposes it is unfinished. I doubt you use Hurd - if you did, you would know it.

The android OS uses the Linux kernel. But it doesn't use any of the GNU tools. So I imagine that it's quite different than the GNU/Linux I run on my computer. Where as I would think that GNU/Hurd would be closer to what I am running now.

When you say Linux you refering to the whole gnu/linux OS or just the linux kernel. Because Linus Torvolds only wrote the kernel not the whole OS. Most of the OS comes from Richard Stallman and the free software foundation. Stallman had a whole OS, he was just missing a functional kernel. Then someone decided to plug the linux kernel into GNU.

I think you are ... By: kinkokonko. on 23 Aug 09, 05:13:40 I think you are inventing the point as this is not stated in the talk. The contention stil remains if you use new House(null) and this succeeds but house.getDoor().toString() fails, the code if more fragile. These are Google talks, Bloch = chief architect, and I find these recomendations a bit our of sort. Given you also have Mockito for stubs I think Mitsuko is completely wrong and his ideas seem to come from laziness in developing the tests. test and real code should be of the same standard
The point is that ... By: miguel47. on 21 Aug 09, 17:29:21 The point is that there should be a separate HouseFactory that is responsible for wiring up the House object. The unit test for the HouseFactory makes sure that Doors are included, the House itself doesn't perform the test.
Very insightful ... By: simarpaul84. on 23 Jul 09, 15:29:07 Very insightful talk that stresses the point that every module/method/constructor should ask for what it needs (dependencies) explicitly. Global State, whether it is from a Singleton/Public Static Instance should be avoided.
It may be better than contex/aspect oriented progamming. Dependecies if passed argument(s), we would know what it needs at compile time; whether a dependency is missing in the context, would be known at run-time when context.get(..) gives null. :)
You are still ... By: kinkokonko. on 08 Mar 09, 11:40:06 You are still missing the point. He is meaning you should use null even for mandatory parameters , as you may be testing a method that doesnt use them. i.e you safe your selve a Mock. Even he doesnt mean this the whole part of the talk is meaningless
This is wrong and pure lazines. thank god he doesnt design Space shuttles, i.e. it would be nice and painted , but when you hit start it would blow up as you havent asserted the flight control is in place.
If you call House( ... By: nieaka. on 04 Mar 09, 18:44:16 If you call House(null) then the provided argument is not an instance of 'Door' and will cause a fatal failure (and your null check will never be considered anyhow). Such a failure would indicate a problem during the creation of door.
14:26 shows example usage of House, and the prior instantiation of Door. If you're passing null to House then instantiation of Door failed, so you already have problems.
Sure, if new House( ... By: nieaka. on 04 Mar 09, 18:41:42 Sure, if new House(null) is valid, you are asserting that house does not require a door. If that's the case, then it is a perfectly valid test.
If that is not the case, then you should pass an object. In the proposed constructor at frame 13:27 you can see this:
House (Door d, Window w, Roof f)
You seem to be ... By: kinkokonko. on 21 Feb 09, 23:21:30 You seem to be missing the point. If it is invalid to have a house without a door you should never compromise the system stability based on laziness in the test. On responsibilitis. Sure you can test the door in isolation but your main responsibility is to produce water tight code. I thinhk his ideas on 'null' are wrong, Null can be considered a friend, that is is you like friends that jump up a cut your throat in your sleep ;-) JSR 308 is a far more improved approach to null checks
Sorry, the 'talking ... By: nieaka. on 06 Feb 09, 17:48:18 Sorry, the 'talking down to the audience' part is for the following post.
Hear his ideas ... By: nieaka. on 06 Feb 09, 17:34:28 Hear his ideas around 7:00-7:40. Giving the house a door in the test is really like mixing testing responsibilities, you will lose the ability to test and isolate house from door.
In regards to his 'talking down to the audience', I disagree. I feel like he boils these things down to a point where you can easily see the substance of the problem, which assists with understanding of these complex and abstract topics. This also helps him cover more material in the short 30 minutes.
No, unit tests end ... By: codeslinger6502. on 27 Jan 09, 18:08:20 No, unit tests end up tightly coupled to the implementation anyway. The unit test is "sacrificial" code tightly coupled to the class under test so it breaks first before production code does.
Your statement "the test AUTHOR is thinking too closely about the implementation" indicates a common misconception about object oriented programming: private object implementation doesn't mean the PROGRAMMER shouldn't know the implementation, it just means other CODE doesn't know the implementation.
(...)
In theory ( ... By: rhamph. on 03 Jan 09, 11:36:19 (...)
In theory (depending on the language, etc) you could have a signaling-dummy-factory that gets passed in an interface. It would then return an object that acts like null, but claims to support the desired interface (or be the desired type).
Pragmatically, that's a bit bulky, and with a safe language you can usually just remove the null checks.
The problem is that ... By: rhamph. on 03 Jan 09, 11:35:54 The problem is that the language uses null to mean "no object needed", whereas the speaker wants it to mean "signaling dummy". The type checking should exclude the former, but not the latter. It's a problem of the language that null exists for every type, rather than requiring a union (or similar polymorphic declaration.)
(blah length limit...)
This is a very good ... By: kinkokonko. on 26 Dec 08, 06:00:26 This is a very good overview though I find views agaist precondition checks very contencious. Basically if you contend new House(null) is valid you are saying that the internal state of the House is ok without a Door. This may not be true. It is often better to ensure the consistent validity of an objects creation upfront rather than allow system fail 2 weeks after booting. I would advise Mocking to Door regardless of your test to only paint it. Donot increase the chances of bugs for ease.

DBC sets the hard contracts and TDD exercises the limits of those contracts (and even ensures violations are caught!)
Good video for the ... By: MattCrypto. on 17 Nov 08, 21:20:56 Good video for the most part, although I'm not convinced about the "no null checking" advice. Passing nulls to show that something "doesn't matter" in that test shows that the test author is thinking too closely about the implementation of the class under test -- which could well change. Ideally, we should really code tests strictly to the contract declared by the class, and the use of nulls would seem to be a fragile shortcut in that light.
Rather than ... By: lh32469. on 14 Nov 08, 18:17:21 Rather than allowing nulls in public constructors why not have another package private constructor that requires no params for Unit testing a particular Class?
