|
|
|
|
use i3test;

my $ws = fresh_workspace;

=head1 DESCRIPTION
|
|
|
|
This module provides convenience methods for i3 testcases. If you notice that a
|
|
certain pattern is present in 5 or more test cases, it should most likely be
|
|
moved into this module.

Gets the number of children on the given workspace and verifies that they match
|
|
the expected amount of children.
