When I run my test class the first few lines will execute but then the logs seem to show it stops executing for no reason.  I get the first two system.debugs so I know it is partially executing.

This Trigger will send an email message if an Account has 8 or more cases created within 7 days. Depending on the status of the four fields in the If/Else block will dictate the destination of the email. If the status is "Active" 1 email is sent to a set email address. If the status is "Implementation" then 2 emails are sent, addresses are grabbed from SOQL.
Any help is appreciated.
