=head1 NAME
i3test::Test - Additional test instructions for use in i3 testcases
=head1 SYNOPSIS
use i3test;
my $ws = fresh_workspace;
is_num_children($ws, 0, 'no containers on this workspace yet');
cmd 'open';
is_num_children($ws, 1, 'one container after "open"');
done_testing;
=head1 DESCRIPTION
This module provides convenience methods for i3 testcases. If you notice that a
certain pattern is present in 5 or more test cases, it should most likely be
moved into this module.
=head1 EXPORT
=head2 is_num_children($workspace, $expected, $test_name)
Gets the number of children on the given workspace and verifies that they match
the expected amount of children.
is_num_children('1', 0, 'no containers on workspace 1 at startup');
=cut
sub is_num_children {
my ($workspace, $num_children, $name) = @_;
my $tb = $CLASS->builder;
my $con = i3test::get_ws($workspace);
$tb->ok(defined($con), "Workspace $workspace exists");
if (!defined($con)) {
$tb->skip("Workspace does not exist, skipping is_num_children");
return;
}
my $got_num_children = scalar @{$con->{nodes}};
$tb->is_num($got_num_children, $num_children, $name);
}
=head2 is_num_fullscreen($workspace, $expected, $test_name)
Gets the number of fullscreen containers on the given workspace and verifies that
they match the expected amount.
is_num_fullscreen('1', 0, 'no fullscreen containers on workspace 1');
=cut
sub is_num_fullscreen {
my ($workspace, $num_fullscreen, $name) = @_;
my $workspace_content = i3test::get_ws($workspace);
my $tb = $CLASS->builder;
my $nodes = scalar grep { $_->{fullscreen_mode} != 0 } @{$workspace_content->{nodes}->[0]->{nodes}};
my $cons = scalar grep { $_->{fullscreen_mode} != 0 } @{$workspace_content->{nodes}};
my $floating = scalar grep { $_->{fullscreen_mode} != 0 } @{$workspace_content->{floating_nodes}->[0]->{nodes}};
$tb->is_num($nodes + $cons + $floating, $num_fullscreen, $name);
}
=head2 cmp_float($a, $b)
Compares floating point numbers C<$a> and C<$b> and returns true if they differ
less then 1e-6.
$tmp = fresh_workspace;
open_window for (1..4);
cmd 'resize grow width 10 px or 25 ppt';
($nodes, $focus) = get_ws_content($tmp);
ok(cmp_float($nodes->[0]->{percent}, 0.166666666666667), 'first window got 16%');
ok(cmp_float($nodes->[1]->{percent}, 0.166666666666667), 'second window got 16%');
ok(cmp_float($nodes->[2]->{percent}, 0.166666666666667), 'third window got 16%');
ok(cmp_float($nodes->[3]->{percent}, 0.50), 'fourth window got 50%');
=cut
sub cmp_float {
my ($a, $b, $name) = @_;
my $tb = $CLASS->builder;
$tb->cmp_ok(abs($a - $b), '<', 1e-6, $name);
}
=head2 does_i3_live
Returns true if the layout tree can still be received from i3.
# i3 used to crash on invalid commands in revision X
cmd 'invalid command';
does_i3_live;
=cut
sub does_i3_live {
my $tree = i3test::i3(i3test::get_socket_path())->get_tree->recv;
my @nodes = @{$tree->{nodes}};
my $tb = $CLASS->builder;
$tb->ok((@nodes > 0), 'i3 still lives');
