Error with Minitest/AssertOutput when global assignment occurs at top level

[mvz]

If a file under test/ contains an assignment to a global variable at the top level, Minitest/AssertOutput will generate an error

Expected behavior

Minitest/AssertOutput ignores the assignment because it doesn't occur in a test case

Actual behavior

RuboCop generates an error message like the following:

An error occurred while Minitest/AssertOutput cop was inspecting /home/matijs/Projects/gir_ffi/test/foo.rb:1:0

Steps to reproduce the problem

Given a project configured for using rubocop-minitest, create a file test/foo.rb containing

$VERBOSE = false

Then run:

$ rubocop test/foo.rb

RuboCop version

0.88.0 (using Parser 2.7.1.4, rubocop-ast 0.1.0, running on ruby 2.7.1 x86_64-linux)
