Subject: tests: introduce is_num_children test
X-Git-Tag: 4.3~44
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=232d6ccce9282795f30c4b64408865e5af3c9905;p=i3%2Fi3

tests: introduce is_num_children test

This makes it clearer what the tests are actually doing and kills quite
a bit of useless repetitions

+=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.
