I have recently published a WordPress plugin and it works great on single sites. I was informed that the plugin is not working correctly on multi-site installations and I understand a few of the reasons why. I have updated the code and need a way to now test my updated code before going to a live customer's multi-site installation.
I have a single site installation of WordPress setup for testing purposes but need to test on a multi-site installation.
From what I can find the only way to do this would be to setup an entire multi-site installation with at least two sites on the network to test my plugin.
Is setting up an entire multi-site installation of WordPress the only/preferred way for plugin developers, or is there a quicker testing environment available.
