# Pre Conditions
This folder should contain any \*.pp files that you want to be included in every test.
A common use of this is defining resources that may not exist in the catalog when you are running tests. For example, if we are using a resource that tries to restart the `pe-puppetserver` service, unless it is compiled on a Puppet Maser the `pe-puppetserver` service will not exist and the catalog will fail to compile. To get around this we can create a .pp file and define the resource like so:
``` puppet
# We are not going to actually have this service anywhere on our servers but
# our code needs to refresh it. This is to trick puppet into doing nothing
service { 'pe-puppetserver':
ensure => 'running',
enable => false,
hasrestart => false, # Force Puppet to use start and stop to restart
start => 'echo "Start"', # This will always exit 0
stop => 'echo "Stop"', # This will also always exit 0
hasstatus => false, # Force puppet to use our command for status
status => 'echo "Status"', # This will always exit 0 and therefore Puppet will think the service is running
provider => 'base',
}
```
This will mean that the `pe-puppetserver` service is in the catalog for spec testing and will even allow you to try to restart it during acceptance tests without the service actually being present.
