From 95a2ec6aab25a666a7163e7ddb9fcbf51bfa4c7e Mon Sep 17 00:00:00 2001 From: Aníbal Limón Date: Wed, 9 Nov 2016 11:09:07 -0600 Subject: oeqa/core/decorator: Add support for OETestDepends MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The OETestDepends decorator could be used over test cases to define some dependency between them. At loading time sorting the tests to grauntee that a test case executes before also raise an exception if found a circular dependency between test cases. At before test case run reviews if the dependency if meet, in the case of don't it skips the test case run.
