# This functions adds a source file as an executable, links that file against
# the common test core and creates a test from it. The first parameter is the
# source file, the second is the name of the executable and the test and the
# last parameter is the template suffix of the test. The template should follow
# the following naming policy: `maxscale.cnf.template.<template name>` and the
# file should be located in the /cnf/ directory.

# Example: to add simple_test.cpp with maxscale.cnf.template.simple_config to the
# test set, the function should be called as follows:
#     add_test_executable(simple_test.cpp simple_test simple_config LABELS some_label)
