ShUnit

When shUnitPlus and the tests are in different directories, shUnitPlus
write an error message.
For example, with the following structure :

errorInShUnitPlus
lib/
|-Shunit/
|-shUnit
|-shUnitPlus


and test file containing :

#!/bin/bash
export SHUNIT_HOME=lib/ShUnit
. $SHUNIT_HOME/shUnit
. $SHUNIT_HOME/shUnitPlus


the output begin with

lib/ShUnit/shUnitPlus: line 11: ./shUnit: no such file or directory

It's very confusing because when test is a success, there is an error
message. I have attached a unit test for this issue :

#!/bin/bash
export SHUNIT_HOME=lib/ShUnit
. $SHUNIT_HOME/shUnit

TestNoErrorMessage() {
errorOutput=`. $SHUNIT_HOME/shUnitPlus 2>&1`
shuStringEqual "" $errorOutput
}

shuStringEqual() {
[ x"${1}" = x"${2}" ]
shuAssert "StringEquals: ${1} vs. ${2}" $?
}
