Emulators

There will be another UI element in DevRiot command set. A combo box that will allow the user which emulators are available to use given the current project. If a project is a smartphone one, then only smartphone SDK emulators will populate the combo box.

Moving to VS 2008

Adding support to the different devices that exist in the Compact and Micro Frameworks is forcing us to move development to VS 2008 from VS 2005 it seems a doable task in a short period of time :-}

Starting on .Net Compact and Micro Frameworks!

This afternoon we started the wiring of DevRiot to the .Net Compact and Micro Framework emulators.

Some considerations:

  • The execution speed will not be as good as DevRiot is on the Desktop Framework. Those are resource constrained frameworks.
  • There will be an smaller amount of threads available to the Load & Stress Engine.
  • The maximum number of tests will not be affected.

Mild and off-target...

After a harmless hack attempt at the wrong site, it was suggested by my isp to harden the site logic. We did so it is robust enough to avoid the easy gotchas, we believe.

Shallow waters

Finally we packaged a shallow/dummy version of DevRiot for .Net. The goal is to make sure the installers work correctly and package the resources needed by the tool to work. No functionality yet.

Random thoughts

The GUI acts now as it should be (more stable). Just a couple of scenarios/bugs in the GG engine and the deployment phase should start in earnest.

The federal catch 22: labour market is in the doldrums. Stimulus vs. outsourcing? Spend more tax payer money that could be sent overseas in 2/3 years? Black Friday purchases shrunk almost 10% in compared to 2008. Not a seat for the faint of heart.

Generics Generator getting a life...

We have hit a can of worms, actually a couple of weeks back, that made the automatic recompilation of tests algorithm working for generic types only or non-generic types only. Obviously this was not acceptable.

This algorithm was rewritten and it looks cleaner and working...

Glad to be back!

After a short trip where I broke the only surfboard I had on the first session and was chased out of the line-up by a shark on the third day finding the last changes made to the engine were less than ideal is a piece of cake.

The trouble is already spotted, thoroughly examined, and almost fixed. The deployment logic will have to wait a tiny bit.

It is nice to see how big companies, and big research institutions continue using "Quality Advantage" on a regular basis.

DevRiot Beta is wating for deployment...

We fixed the nested generics problems. It looks good enough to let people really find its problems.

This leaves DevRiot beta ready to be used once the deployer method is ready. Will be off the grid on a 2-week friends & family & surfing trip. A break is called for.

Nested Generics...

We are experiencing a little bit of trouble with the way nested generic types are being stored. In the meantime a couple of buttons/shortcuts were added so the engine can be disengaged when a series of builds trigger continuously DevRiot's automatic build.

Next week will be a simple install and finish the engine deployment method. Beta is just a short steps away...

1,600 T

I have been trying to squeeze more than 1,600 concurrent threads out the engine without changing any settings. No luck. Obviously, it will need a closer, slower look and better tools. Still 1,600 is a number that can be useful, specially when one invests 30 seconds or less to create, use, and harvest.

Generics core

The interesting thing about last post is that the cpu utilization averaged 50% during the entire rebuilding of the suite (3.4 million tests) If memory is managed with common sense the throughput of DevRiot in multi-core machines with several cpu would be hard to match (mine is a duo)

On the down side the internal compiler choked at complex generic types like:

"ns1.t2<ns1.t1<system.byte[][],system.byte>,System.Byte,System.Int32>[][][]"

Problem solved. Smooth..

3,400,003 and counting...

We spent the weekend fixing an old disconnection problem when running large amount of tests. We fixed it. It works like a champ, it executed some really ineffient code for 24 hours straight without a bleep.

We also managed to squeeze 3.4 million tests with some complexity: runtime generics, different levels of validation and the engine ran like a champ. The pudding:

DevRiot for .Net Beta Update...

Having a little bit of trouble with nested generic types and bulk creation (25,000 or more) but other than stable an smooth.

BTW properties will not be supported for this beta.

Another Short Update

DevRiot for .Net is coming along well. We have spent extra time ironing out the code that deals with System.Object, interfaces, and abstract types because it is adding more dynamic input to an already dynamic engine. 

Since the user never writes code, tests are generated/executed on the fly, the former types add more complexity to the logic so the ironing of bugs turns more complex too.

Hit a unexpected behavior between the recompiling process of DevRiot and VS debugger. Specially annoying when handling 10,000 tests or more.

To Shake!

The weekend was busy as any impending across-the-Atlantic move would demand but I managed to download Chrome (I have been using Firefox for years) and poked around the web.

I tried to run the technorati searches that we appear on but it didn't work. It may be a matter of sgining-in, the reading was interesting nevertheless.

Some of the posts were pro unit test other against, Agitar, Agile, etc.

A blogger explained that Agile is an incremental methodology where the developer decides what to work on next. A couple of them stated in other posts that a lot of their collegues just don't write unit-tests.

It is not surprising: as soon as the decision of what to work on is made by the over-pressured project manager, something's got to give.

Agitar's demise may be a consequence of the previous, but it also missed some crucial requirements: it just worked unit tests, the underlying framework was somewhat limited. It also solved just part of a customer problem: product quality. By only adding a lock statement the whole thing lost compass.

BTW, Chrome seems very useful...

Params, Threads, Generics This is another progress demo. It involves: dynamically allocating params, genereics, threads, and switching between classes. Everything is handled transparently and effortlessly to the user. With such a small learning curve, ease of use, and blasting speeds the testing "Total Costs of Ownership" should be extremely low while attaining effectiveness never seen before.

After cleaning up some bugs, a task that is still going, here is another sampler: a 500 thread session, with generics included, ran twice under 3 minutes from scratch.

That is generics type, tests + threads creation, and run. Everything completely synchronized.

General Dynamic Fixtures

This is the first work-in-progress report in a while. It shows how DevRiot dynamically generates, stores, and retrieves tests between sessions.

The "fixtures" are handled dynamically. We can mix and match the generics parameter types on-the-fly, keeping the engineers effort easy, flexible, and quick. Extremely quick.

Very few tools on the market can offer such a low Cost of Ownership, in the short or long run :-}

Summer Blues Report...

I must admit that moving suites/tests from storage to binary form has been a challenge. It has become more difficult than DevRiot for Java because it has more features to take care of.

Plugging the plug-in

We are paying the error of working while sick on a key piece of code regeneration. Bad code, or at least worse than usual, that needs rewriting.

But it also has given us the opportunity of thinking about deployment.

We are toying with the idea of adopting "perpetual delivery" mode. Since the engine is not larger than 150K, downloading it can part of the add-in setup.

The S option seems to be a viable option!

Good ol' SQL improved the serialization of tests by leaps and bounds.

Now it takes less than minute and a half to create and store 5,000,000 tests. Before this much time was needed for 100,000.

The S Option

Given the enormous amount of tests can be generated with DevRiot, our old serialization architecture is proving not up-to-par.

SQL seems to be most logical way to handle this.

Well keep you posted. Sorry for the inconvenience!

Less than two minutes...

We have been tweaking around the serializer (getting rid of duplicate IO work) and writing, storing 100,000 tests takes less than 2 minutes. The development costs aren't why they used to be...

A more realistic approach to this feature can be: there is a method that takes a matrix and returns a modified version of it. Given the nature of matrices, a user could create a "base" test batch with a baseline matrix then modify the individual matrices with minimum effort.

Storage...

I must have to say that developing code to serialize large number of objects can be quite time consuming.

It does not register

Well after having a question/post mysteriously disappear from the VSX forum, which is a first, I decided not to wait more on that.

Two registry entries will allow the user to gauge according their HW configuration what the max number of user/threads DevRiot can handle and the emergency TTL (when all current users/threads are harvested to avoid hosing down the box)

To be a product that has a really small exposure, there a lot of big copycats :-}

Time To Change...

Well after fiddling around with the load/stress engine + 1,600 threads/users for a while, I think it makes more sense to let users set the TTL per test.

It is easier for the user to set it according to their knowledge of the code than use any predefined formula.

It also becomes part of the verification data of the test which should be useful.

In addition, there is the Assertion, Out-Of-Scope, etc, in a codeless, easy-to-use, low-skills-needed sort of way.

VUT Threads...

This is almost identical to the previous demo but with the difference that the Load/Stress testing engine is hooked up.


Note that the video follows the same script as the previous one, so no PrivateObject API or coding or scripting. Even the thread creation, execution, and harvest.


The other difference is that we intentionally tried to add a test without pre-compiling a parameter so the tool could complain :-] Three threads are created and used against the method under test.

Automation?

We are currently working on the ContextMenu manager. It should be a breeze since the Generics support actually meant a major addition of functionality.

GUI support should come soon too, its major piece of functionality is ready to wire.

Which lead me to look at the Automation library that MS has on .Net 3.5-VS 2008. It is not a surprise , and not a particularly interesting competitor.

First is stuck in PC land. None of the major classes are supported by the Compact Framework.


Second, it is another hard to digest class/method behemoth.

I guess they are not competing on usability and product definition/differentiation...

These two are a couple of progress snapshots from the Generics Engine.

To show the flexibility and ease-of-use of DevRiot's Visual Unit Testing(tm) technology here we have a generic method that takes 3 generic parameters. Each one of them is a bound generic type A made of an array of bound generic type B. Type B is made of an array int.

General Complexity

The Generics Generator is pretty smooth now:

This is an snapshot of a that involves: generic method, out parameter, multidimensional arrays, out of scope data (PrivateObject in VS parlance).

And it is the same as if it a method that takes and returns an integer. The user just spends time on what it matters most: substance and not boiler plate noise.

None of the competitors can achieve such a level of usability and ease-of-use. Let alone the execution speeds. We are pretty close to wire up the GUI testing engine...

Anything VUT...

Visual Unit Testing, this is the acronym that best describes the visual nature of DevRiot's user experience. It also applies to the GUI testing engine but there are more salient features that describe DevRiot's GUI testing engine: device independence and ditching the capture-and-replay paradigm.
