# create_test_sourcelist

Create a test driver and source list for building test programs.

    create_test_sourcelist(<sourceListName> <driverName>
                           <tests> ...
                           [EXTRA_INCLUDE <include>]
                           [FUNCTION <function>])

A test driver is a program that links together many small tests into a single executable. This is useful when building static executables with large libraries to shrink the total required size. The list of source files needed to build the test driver will be in `sourceListName`. `driverName` is the name of the test driver program. The rest of the arguments consist of a list of test source files and can be semicolon separated. Each test source file should have a function in it that is the same name as the file with no extension (`foo.cxx` should have `int foo(int, char*[]);`). `driverName` will be able to call each of the tests by name on the command line. If `EXTRA_INCLUDE` is specified, then the next argument is included into the generated file. If `FUNCTION` is specified, then the next argument is taken as a function name that is passed pointers to `argc` and `argv`. This can be used to add extra command line processing to each test. The `CMAKE_TESTDRIVER_BEFORE_TESTMAIN` cmake variable can be set to have code that will be placed directly before calling the test `main` function. `CMAKE_TESTDRIVER_AFTER_TESTMAIN` can be set to have code that will be placed directly after the call to the test `main` function.
