LTest (short for LambdaTest) is a C++ 11 test library based on lambdas.
Because the usage of lambdas, the library was designed for compilers supporting the C++ 11 standard or higher. LTest does not make use of any macro constructs for the tests. Therefore you write plain C++ test code without any macro magic. LTests supports programmatic access to the test results, multiple output formats (e.g. the xunit xml output for eclipse or jenkins CI servers) and parallel test execution.
#include "LTest.h"
bool is_leap_year(unsigned int year){
return (year % 4 == 0 and year % 100 != 0) or year % 400 == 0;
}
TestSuite suite = {
ltest().addTest("test is leap year 2014 : ", [](){
return !is_leap_year(2014);
}),
ltest().addTest("test is leap year 1900 : ", [](){
return !is_leap_year(1900);
}),
ltest().addTest("test is leap year 2000 : ", [](){
return is_leap_year(2000);
})
};
int main() {
ltest().run(suite);
return 0;
}
LTest consists just of a set of header and implementation files. You can add our source code to your test folder. We are destributing LTest this way to avoid building it for all available plattforms. We only use "normal" features of C++ 11 which should be available on the most plattforms. See developer info for the compilers we already support and tested with.
We expect that you will create some test code which should be linked to your production code, testing your functionality. So in your project you should have an test-src folder which will contain all your (Ltest)-testcode. You should also embed this git-repository into this folder (you can use git submodules to do so). Now you can create your testcode like in the example above and run it using a main function. Note that the production code under test can't contain another main function, because you can have only one of them. Don't forget to include the folder, in which LTest.h is located, into your compile path (for g++ for example use -I and -L to inlude and link against this folder). For more detailed information about using LTest, please visit our wiki! Happy testing!
LTest Compiles with:
- GNU GCC on Linux (g++ 4.8.2)
- MinGW 32 and 64 bit
We develop this project using the CodeBlocks IDE. There is a buildscript called build.sh to also build LTest headless. Note: As described in the building section you just need to compile LTest with your tests, there is no need to build LTest in front. Developing enhancements and fixes to LTest is therefore quite simple too. We have an LTestUse module, which can be used for easy testing of your changes.

- To export the test results, the creation of XML-XUnit datafile was implemented using the RapidXml C++ library. Thanks to Marcin Kalicinski for his great work!
