It happens all too often, it works on local, then the code is pushed and it fails miserably. Or worst, it looks like working but few hours later the client tries out a major feature and find an explosion.

The reasons are various, a need-to-be writable directory, a required extension, etc.

This module simply test for those various stupid big cracks and either respond ok or explode loudly (with a 500). So drop the module and point your browser to /smoke-test. Some of the tests can be configured in application.ini.

smoke-test.phpversion = 5.4
smoke-test.extensions[] = iconv
smoke-test.extensions[] = gettext
smoke-test.writables[] = APPLICATION_PATH "/../data/uploads"
smoke-test.readables[] = APPLICATION_PATH "/../public/modules/admin/static/libs/foo.min.js"
smoke-test.latests.vendor.out = APPLICATION_PATH "/../public/modules/admin/static/libs/vendor.min.js"
smoke-test.latests.vendor.src = APPLICATION_PATH "/../public/modules/admin/static/libs/vendor"

The code is here. The elephant image is from riosriosrios. Got a crack ? fork !
