= NAME =
test_pre_check

= SYNOPSIS =
 * test_pre_check

= DESCRIPTION =
This function is defined in the base test script for a test, and executes
any checks required to make sure any pre-requisites for this test are
set up and ready.

This function is called from [[function_pre_test|pre_test]], before any other
test operations have occurred (but after the connection to the target is
established).

== Commonly called functions or programs ==
This function can contain calls to just about any command, but there are some
common commands used for building Linux source
 * assert_define  - used to verify that an environment needed for this test is defined
 * is_on_target - used to verify that a program or file needed for this test is on the target device

= EXAMPLES =
Some sample contents are:
{{{#!YellowBox
function test_pre_check {
    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
}
}}}

= ENVIRONMENT and ARGUMENTS =
A number of environment variables are set (see [[Core interfaces]] and [[Variables]])

There are no arguments to this function.


= RETURN =
returns non-zero for error.  Usually, if there is some problem,
one of the functions called by test_pre_check will abort the current test.

= SOURCE =
Located in the base script for each test.  The base test scripts are located in /fuego-core/engine/tests/<test_name>.

An example path would be: ''/fuego-core/engine/tests/Functional.hello_world/fuego_test.sh'' (inside the Docker container)
