Failing tests on fresh install

[NikolaGavric94]

On fresh package install after running install.sh there is a lot of core tests failing due to wrong indendation/spaces. Also there is an issue when starting tests from operating system other than Linux because of wget which is not pre-installed on OSX or Win. And also not able to run clean.sh from outside lumen-test folder.

Expected Behavior

All the core tests should pass.

After running install.sh, codecept.phar should exist inside lumen-test.

Being able to run clean.sh outside of lumen-test folder.

Current Behavior

Not all core tests pass.

After running install.sh I get an error wget command not found.

After running clean.sh outside of lumen-test folder I get a bunch of 'File doesn't exist' issues.

Possible Solution

Remove all indentation inside stubs to avoid tests failing.

Install either with curl or wget.

Do all operations inside clean.sh relative to it's parent and not current dir.

Steps to Reproduce

#	Command	Error
1.	git clone _repo
2.	sh install.sh	wget command not found
3.	sh test.sh	A bunch of errors in core tests
4.	cd lumen-test
5.	sh clean.sh	api/routes not found

Context (Environment)

Testing env - Trying to fix the failing core tests and optimize the shell scripts a bit.

Possible Implementation
