A CMake-Setup is provided.

demo.F90:

program good_test

  use unit_test

  implicit none

  type(test_suite_type) :: specific_suite

  ! example with default suite
  call test_suite_init()
  call test_case_create('Test 1')

  ! By sending macros __FILE__ and __LINE__, report will print the file and line number where assertion fails.
  call assert_approximate(1.0, 2.0, __FILE__, __LINE__) ! line 14

  ! report the complete suite
  call test_suite_report()

  ! finalize
  call test_case_final()

  ! example with specific suite
  call test_suite_init('my specific test suite', specific_suite)
  call test_case_create('Specific Test 1', specific_suite)
  ! suite = SUITE need in this case (cause optional argument eps, file_name, line_number is missing)
  call assert_approximate(1.0, 2.0, suite=specific_suite)

  call test_case_create('Specific Test 2', specific_suite)
  ! suite = SUITE need in this case (cause optional argument eps is missing)
  call assert_equal(1.0, 2.0, __FILE__, __LINE__,  suite=specific_suite)

  call test_case_create('Specific Test 3', specific_suite)
  call assert_approximate(1.0, 2.0, __FILE__, __LINE__, 1E-0, specific_suite)

  ! report a test_case
  call test_case_report('Specific Test 2', specific_suite)

  ! report the complete suite
  call test_suite_report(specific_suite)

  ! finalize
  call test_suite_final(specific_suite)

end program good_test
