CukeBins allows Cucumber to support step definitions written in C++
2+
3+
4+
It is designed to support several testing backends and communication
5+
methods, but for now there is just one implementation using:
6+
7+
- GTest (Google C++ Testing Framework)
8+
- Wire Protocol
9+
10+
11+
The current library is header-only, so it doesn't need to be compiled
12+
separately, but it needs the following libraries at link time:
13+
14+
- Boost 1.40 - http://www.boost.org/
15+
Should work with some previous versions too, but it wasn't tested
16+
- GTest 1.4+ - http://code.google.com/p/googletest/
17+
Needed by the test suite and the GTest implementation. Works with
18+
GTest 1.4 and 1.5 (not tested with 1.3)
19+
20+
This header-only library is included in the source code:
21+
22+
- JSON Spirit - http://www.codeproject.com/KB/recipes/JSON_Spirit.aspx
23+
Needed by the Wire Protocol connector
24+
25+
26+
CukeBins includes a sample borrowed from Cuke4Nuke that uses the same
27+
feature definitions but tests a C++ implementation. To run the tests
28+
and the example, you need the following external tool:
29+
30+
- CMake 2.8 - http://www.cmake.org/
31+
2.8 because it needs FindGTest
32+
33+
To build the tests and the sample application:
34+
35+
cmake -E make_directory build
36+
cmake -E chdir build cmake ..
37+
cmake --build build
38+
cmake --build build --target test
39+
40+
To run the example on Unix:
41+
42+
build/examples/Calc/CalculatorSteps >/dev/null &
43+
cucumber examples/Calc/CalcFeatures
44+
45+
To run the example on Windows (NMake):
46+
47+
start build\examples\Calc\CalculatorSteps.exe
48+
cucumber examples\Calc\CalcFeatures
49+
50+
51+
CMake hints:
52+
53+
- For GTest, set GTEST_ROOT to the location of the GTest install prefix
54+
If the GTest libraries were installed in /usr/local/lib and the includes
55+
are in /usr/local/include/gtest, then add "-DGTEST_ROOT=/usr/local" to
56+
the cmake command line
57+
58+
- For Boost, set BOOST_ROOT to the location of the Boost install prefix
59+
if CMake has troubles finding it
60+
