Update test.bash and documentation

[holgerfriedrich]

Test.bash is outdated.

• In parametrize for production, test and verbose debugging install runs #683 Dockerfile has been renamed. We need to update testing related scripts
  and CONTRIBUTING.md, README.md docker build -f Dockerfile.openhabian-x86 ... OR decide to rename Dockerfile.openhabian-x86 to Dockerfile (affects .travis.yml)
• Shellcheck test is incomplete (build.bash is not shellchecked, see .travis.yml for reference)
• Feature request: add calling bats test w/o Docker
• Add something about test.bash to documentation

Did you try build.bash after #684 meanwhile ?
Latest is shellchecked BTW.

[holgerfriedrich]

@mstormi I think you got me wrong, test.bash does not do it, so pre-commit testing might overlook it

[mstormi]

from .travis.yml: build.bash is shellchecked
- shellcheck -x -s bash openhabian-setup.sh functions/.bash build-image/.bash build.bash && echo "shellcheck - OK"

[mstormi]

btw does building an image work ? Would like to provide a new one to contain the 02/2020 update from raspberry.org plus our pre-fetched java.

[holgerfriedrich]

@mstormi it should. I started using the image 1.6 milestone to collect what is essential from my point of view.

[mstormi]

haeh? I didn't catch that.
Won't wait for 1.6, that would be in time for bullseye upgrade.

[holgerfriedrich]

For me 1.6 is just next image milestone. I did remove "bullseye" from title.... bullseye is years away from now

[mstormi]

Well usually we only ever released images together with debian upgrades so I was thinking to call the next 1.5.1 then 1.6 would be for bullseye.
Then again, the Java upgrade also is pretty substantial. We can discuss for sure. Or roll dices ;-)

@ecdye did your recent update on test.bash affect or fix this ?

[ecdye]

It should have, yes (once #938 is merged).
