From bccac55cf99fd4cd0d21bc1ad5e0ef16a762d74f Mon Sep 17 00:00:00 2001 From: Harald Eilertsen Date: Sat, 15 Jun 2024 11:53:00 +0200 Subject: tests: Add some tests for the Zotlabs\Magic module. Only tests the delegate functionality at the moment. This patch also includes some minor fixes to the Magic module, triggered by the tests with empty destination URL's. --- Zotlabs/Module/Magic.php | 8 ++- tests/unit/Module/MagicTest.php | 109 ++++++++++++++++++++++++++++++++++++++++ 2 files changed, 115 insertions(+), 2 deletions(-) create mode 100644 tests/unit/Module/MagicTest.php diff --git a/Zotlabs/Module/Magic.php b/Zotlabs/Module/Magic.php index 8259f7d39..deda4255d 100644 --- a/Zotlabs/Module/Magic.php +++ b/Zotlabs/Module/Magic.php @@ -40,7 +40,11 @@ class Magic extends Controller { goaway($dest); } - $basepath = $parsed['scheme'] .
