Main functionalities

Add unit/system level tests

Semantically there is no difference between unit tests and system level tests. This way all tests can be written in Eiffel. A test is a routine in a class inheriting from TEST_SET. Test routines must be exported to any and have the prefix test.

Example unit tests test_append and test_boolean

class TEST_STRING
 
inherit
 
    TEST_SET
        redefine
            set_up
        end
 
feature {NONE} -- Initialization
 
    set_up
        do
            create s.make (10)
        end
 
feature -- Access
 
    s: STRING
 
feature -- Test routines
 
    test_append
        require
            set_up: s /= Void and then s.is_empty
        do
            s.append ("12345")
            assert_string_equality ("append", s, "12345")
        end
 
    test_boolean
        require
            set_up: s /= Void and then s.is_empty
        do
            s.append ("True")
            assert_true ("boolean", s.is_boolean and then s.to_boolean)
        end
 
end

Example system level test test_version (Note: SYSTEM_LEVEL_TEST_SET inherits from TEST_SET and provides basic functionality for executing external commands, including the system currently under development):

class TEST_MY_APP
 
inherit
 
    SYSTEM_LEVEL_TEST_SET
 
feature -- Test routines
 
    test_version
        do
            run_system_with_args ("--version")
            assert_string_equality ("version", last_output, "my_app version 0.1")
        end
 
end
