​Fluent Bit comes with some unit test programs that uses the library mode to ingest data and test the output. The tests are based on Google Test suite and requires a C++ compiler.

Requirements

In order to build and run the tests, your system needs a C++ compiler and an installed version of gtest. On Debian/Ubuntu systems the following commands will install the dependencies:

$ sudo apt-get install g++ libgtest-dev

Note that libgtest-dev will only install the sources of the test suite, you need to take some extra steps to make this work:

$ cd /usr/src/gtest
$ sudo cmake .
$ sudo make
$ sudo cp libg* /usr/lib/

Enable Tests

By default Fluent Bit have the tests disabled, you need to append the ENABLE_TESTS option to your cmake line, e.g:

$ cd build/
$ cmake -DFLB_TESTS=ON ../

Running Tests

To run the tests just issue the following command:

$ make test
