i am using a small php microframework and keep getting an error Uncaught Error: Undefined constant "mu"

the framework code:

the testing page code:
<?php
require(mu.php);
(new µ)
->get('/hello', function () {

// Thank you, any assistance is highly appreciated.

GroovyTemplate of test runner throws exceptions and won't show error detail

Sometimes when a scalatest fails, Play test framework does not report the cause of the failure, instead I see the following. Any ideas why?
Reporter completed abruptly with an exception after receiving event:

Update:
It happened because of the following exception that the test had triggered. Does the test framework supposed to blow up when a test throws an exception?
java.util.NoSuchElementException
at scala.collection.IterableLike$class.head(IterableLike.scala:101)
at scala.xml.NodeSeq.head(NodeSeq.scala:43)

what does this error mean in xcode debugger window?

It means that you have a UITableViewController but it's view isn't actually a UITableView. Has this the other day. Check what the class of the controller is in interface builder.
You could do in gdb
