function assert define

NAME [edit section]

assert_define

SYNOPSIS [edit section]

  • assert_define <varname> ["message words"]

DESCRIPTION [edit section]

This function checks that the indicated variable is defined. Otherwise, it aborts the currently running test.

An optional message can be provided for the abort call.

EXAMPLES [edit section]

Here are some sample invocations:
        assert_define FUNCTIONAL_BC_EXPR
        assert_define FUNCTIONAL_BC_RESULT

        is_on_target bc BC_PROGRAM /bin:/usr/bin:/usr/local/bin
        assert_define BC_PROGRAM "Missing program 'bc' on target"

This second example shows use of assert_define following a call to is_on_target, as well as the use of an optional message if the variable is not defined.

ENVIRONMENT and ARGUMENTS [edit section]

The positional arguments to assert_define are:
  • $1 - the variable to check the definition of
  • $2 - an optional message to use if the variable is not defined

RETURN [edit section]

Returns non-zero on error.
