A simple unit test framework
So what is btest?
This btest library is a vastly reduced implementation of a
testing framework of a similar flavor. I think most users who use
googletest have a good idea of how it works, but I wanted to try
to implement something similar, to really see how it's done.
The internals of btest or googletest must:
- define tests during static initialization
- register tests into a central registry/controller
- provide runtime mechanisms to flag tests' results in registry
- use abstract classes and object factories to use instances
As you can probably tell, btest is more of a framework for
trying implementation ideas, and not a replacement for
googletest.
btest has a drastically reduced feature set compared to googletest.
However, it implements the most important testing features, most easily
reported in this table.
| Feature | btest | gtest |
|---|---|---|
| basic tests | yes | yes |
| test fixtures | yes | yes |
| DISABLED_ tests | yes | yes |
| Test filtering | no | yes |
| Global environment | no | yes |
| Run order randomization | no | yes |
| Death tests | no | yes |
If you'd like to play with this, go ahead.
btest is currently managed with cmake, and uses C++03 for its
implementation. From the toplevel directory, run these commands:
$ cd path/to/btest
$ mkdir build
$ cd build
$ cmake ..
$ make -j
