======================================================
sfntly C++ port uses Google testing framework for unit testing.
All test cases are under src/test.
To run the unit test, you need to compile sfntly first, then copy
Tuffy.ttf from data/ext to the folder that unit\_test(.exe) is located.
Run the unit\_test.
If you are only interested in one test case, for example, you are
working on name table and only wants name editing test, you can use the
gtest\_filter flag in command line.
``` {.prettyprint}
unit_test --gtest_filter=NameEditing.*
```
For more info regarding running a subset of gtest, please see [GTest
Advanced
Guide](http://code.google.com/p/googletest/wiki/V1_6_AdvancedGuide).
Its strongly suggested to run unit\_tests with valgrind. The following
example shows a typical test command
``` {.prettyprint}
valgrind --leak-check=full -v ./unit_test --gtest_filter=*.*-FontData.*
```
FontData tests are the longest and you may want to bypass them during
development. They shall be run in bots, however.
