Dumping global variables in Robot Framework when a test fails?

Question

I have a doubtful pleasure to work with legacy tests written in Robot Framework that abuse usage of global variables.

I would like all global variables to be dumped when the test fails.

How can I achieve that?

You can call the built-in keyword Log Variables in a suite teardown or test teardown.

Here's an example that uses a suite teardown:

*** Settings ***
Suite Teardown   log variables

*** Test cases ***
Test case 1
    set global variable  ${FOO}  Hello
    set global variable  ${BAR}  World
    Fail
