FRUIT has assertion, fixture, setup, teardown, report, spec, driver generation and uses Rake (Ruby build utility) used as build tool.

FRUIT core is written in FORTRAN , so one can use it without need of installing any additional software.

...

• Fortran compiler (eg. gfortran)
• fruit.f90 source file: https://github.com/mortele/FRUIT/blob/master/src/fruit.f90
• fruit_processor_gem files: https://github.com/mortele/FRUIT/tree/master/fruit_processor_gem
• Ruby
• Rake

Which FRUIT to use

If you create small project with several modules and not so many subroutines, use FORTRAN only version. You need only to download one file and add it to build script, but you need also to fill test_driver file manually.

...

FRUIT Fortran only vs FRUIT Fortran + Ruby

FRUIT Fortran only

• Good for small project
• Good if you do not need setup and teardown subroutines (otherwise you need to create and maintain additional basket file)
• You will need to reate test driver on your own

FRUIT Fortran + Ruby

• Good for complex projects
• Good if you need setup and teardown subroutines
• Needs Ruby interpreter
• You will need only to point test and source files in CMakeLists files

Avaivable tools

subroutines:
	assert_equals
	assert_not_equals
	assert_true
	assert_false
	setup
	teardown

!examples with different types:

!integers and reals
	assert_equals(a,b)
	assert_equals(a,b,"Message when assert fails")
	assert_not_equals(a,b)
	assert_not_equals(a,b,"Message when assert fails") 

!NOTE: "Message when assert fails" is optional

!reals with tolerance 
	assert_equals(a,b,tolerance)

!booleans and expressions
	assert_true(expression)
	assert_false(expression)

!strings
	assert_equals("abc","abc")
	assert_not_equals("abc","abc")
