Failing functional tests in Lumen
This blog post was originally published a little while ago. Please consider that it may no longer be relevant or even accurate.
There appears to be an unresolved bug in the current release of Lumen which causes your functional tests to fail. Your first test will pass (if it's meant to) but any following tests will fail without doubt. If you actually catch the error causing the functional test to return a 500 response code, you'll likely see this:
You can read more about the issue here on GitHub which links to other discussions. There appears to be confusion about whether the issue is related to database migrations or the use of facades.
Either way, in order to get your suite running correctly you can add the following
setUp() method to your application's
TestCase. Though Lumen is already refreshing the application between tests it seems like forcing it to refresh twice actually makes everything work. This is a short-term solution until the bug is fixed in Lumen, which is hopefully very soon.
Edit (June 2015): This issue appears to be resolved in Lumen 5.1.
