simple test to check bootstrap oneliner

[Morriz]

Is your feature request related to a problem? Please describe.

When people use the bootstrap one-liner mentioned on this page, we want to make sure that it works correctly.

Describe the solution you'd like

The script has a unit test that checks if the env folder is created. The flag skip_demo_files will be removed. Furthermore, the repository has integration tests that capture script behaviour about multiple executions and exit codes.

D.o.d.

• Multi-staged build in the Dockerfile, making it portable.
• bin/tests/*.sh called by bats.
• Check if the env folder is created (unit tests).
• Check multiple executions and exit codes (integration tests).
• Refactor such that the flag skip_demo_files will be removed.
• Write documentation.
