Delphi Latest Version

So far, this is a single project. We are trying to write tests for bugs. Some bugs fail in earlier versions and pass in newer versions. The question then becomes, how do we handle the differences between versions?

How about this proposal: We have a separate branch for each version starting with, say XE. Then, the XE2 branch will split off the XE branch, the XE3 branch will split off the XE2 branch, and XE4 off of XE3. This way, we can migrate tests forward very easily be merging changes forward. People can work on the branch that matches their Delphi version, and their work can naturally be migrated forward to the later version branches. Failing tests aren't the concern. Failing to compile is.

As a 'Foundations' book, it doesn't touch much on the IDE features, but it contains some advanced topics as well. Based on object Pascal programming language, the latest version of Delphi includes facilities for rapidly building or converting an application into a Web service.

Take Generics.Collections as an example. From 2010 to XE a ToArray function was added to TEnumerable and it's descendents, TQueue got a Capacity property and TThreadedQueue was added.

From XE to XE2 TDictionary.DoRemove was changed from a procedure to a function returning TValue. From XE2 to XE3 TArrayManager, TMoveArrayManager,TManualArrayManager and TThreadList were added and TList gained 7 new methods and a property. Tests written against these additions can't be compiled with older versions of the RTL. I think perhaps the simplest route would be a project for each version and a test unit for each version with conditional compilation being reserved for cases where a signature has changed. My concern with a failing tests project is that it will wind up requiring a lot of shuffling of test cases from one version to the next.

Let's say we actually succeeded to achieve 100% code coverage for 2010 and found 10% of test cases fail. Those failing cases are moved into separate units so they can be added to the DelphiUnitTestsFailing project. Now let's say XE fixed half of those failing tests, regressed another 2% and introduced an additional 2% of new code with failing tests. So now the fixed tests have to be merged back into the passing test units and the new failures need to be separated out into their own units. That's a lot of code churn just to isolate failing tests. Even if you kept all the tests together and used conditionals to turn tests on and off it'd still be a lot of code churn. Getting all tests to pass isn't really what this project is doing because we don't control the production code. Tupoksi kepala sekolah sd pdf.

That'll be Embarcadero's job. This project is simply identifying the bugs and providing immediate feedback when the bugs are fixed. I have envisioned a spin off community project that attempts to fix RTL/VCL bugs akin to Andreas Hausladen's using this project for verification. This would allow the developer community to work around bugs in end-of-life versions and between official releases.
