![]() No need to install anything on Lazarus/FPC. on Windows you need to install the DLL, e.g. ![]() works perfectly fine (tested on Windows and Linux, I suppose MacOS will work too. Those days I'm using libcurl with the bindings that are supplied with Lazarus/FPC. And all the new methods use 0-based indices for strings. But now they added OOP like string functions and it became weirder. It is already weird, but you can get used to it. You can have classes with ARC which are almost memory safe, but only if you use an interface.Īrray indices start with 0, string indices start with 1. Except, in Pascal they are also COM interfaces and add automated reference counting to a class. Everyone here knows how they work and in Pascal they work in the same way. They specify some methods, but not their implementation. Interfaces are a very common concept in OOP languages. Also it looks like it cannot be used with a slice of length 0, unless it is a slice of an array of length 0. There is a type to store a slice of an array, but it can only be used during function calls, so no one ever uses it. There is a type to store sets of integers, but you cannot have more than 256 elements There is mutability xor aliasing, but only for strings There is automated reference counting to get memory safety, but only for strings and arrays (and also interfaces but we get to that later) It is twice as weird in FreePascal, because the developers cannot decide if they want to make their own language or be Delphi compatible. TAssert A class which implements a series of ’Assert’ commands.They always implement some language feature, but then put some weird, arbitrary restriction on it. EAssertionFailedError This is the basic exception, indicating that a test has failed. ![]() The following classes can be found in this unit: TTest The parent class for TTestCase and TTestSuite. It contains a series of base classes, which make up the test system. 2 FPCunit: Units and Classes The heart of the FPCUnit testing system is implemented in the fpcunit unit. Vincent Snijders made a nice package to facilitate creating ad running tests for the FPCunit framework in the Lazarus IDE. The implementation was made by Dean Zobec, and is included in the FCL (Free Component Library) shipped with Free Pascal. Since the 1.9.8 version of Free Pascal (and version 0.9.7 beta of Lazarus), such an implementation is also available for Free Pascal: FPCunit. (a ’Listener’) Over time, many implementations of this idea have appeared, for all kinds of programming languages. The output of this run can be analyzed by yet another class. These classes are then registered in a test suite registry, and can be run. It does this by providing a few base classes (testcases) of which the tester must make a descendent, and which should include test code for the routines to be tested. Basically, the JUnit test framework provides a controlled environment to perform tests of software routines. This has culminated in a series of test frameworks, similar to the original JUnit test framework. 1 Introduction Lots of people are firm believers in the concept of writing test code for classes or routines, as part of the development effort.
