test/system: Refactor tests using bats-support and bats-assert

Browse source 
The bats-support[0] and bats-assert[1] libraries extend the
capabilities of bats[2]. Mainly, bats-assert is very useful for clean
checking of values/outputs/return codes.

Apart from updating the cases to use the libraries, the test cases have
been restructured in a way that they don't depend on each other anymore.
This required major changes in the helpers.bats file.

Overall, the tests are cleaner to read and easier to extend due to the
test cases being independent.

Some slight changes were made to the test cases themselves. Should not
alter their final behaviour.

There will be a follow up commit that will take care of downloading of
the tested images locally and caching them using Skopeo to speedup the
tests and try to resolve network problems when pulling the images that
we experienced in the past.

# System tests
These tests are built with BATS (Bash Automated Testing System). They are
strongly influenced by the [libpod](https://github.com/containers/libpod)
project.
These tests are built with BATS (Bash Automated Testing System).
The tests are meant to ensure that Toolbox's functionality remains stable
throughout updates of both Toolbox and Podman/libpod.
## Structure
**Warning**: The tests are not executed in an isolated environment. They affect
the system where they are run.
- **0xx (Info)**
- Commands that are not dependent on the presence/number of containers or
images. eg., version, help, etc..
- **1xx (Initialization)**
- Commands (list, create) when Toolbox has not really been used, yet.
- It tries to list an empty list, creates several containers (default one
and several with custom names and images).
- **2xx (Usage)**
- The created containers are used for the first time testing the
initialization (CMD of the container).
- Not all containers will be used because in the *Cleanup* phase we want to
try removing containers in both running and not running states.
- **3xx (Cleanup)**
- In this section the containers and images from the previous *phases* are
removed.
- There is a difference between removing running and not running containers.
We need to check the right behaviour.
## Dependencies
These tests use a few standard libraries for BATS which help with clarity
and consistency. In order to use it you need to download them to the `libs`
directory:
```
# Go to the Toolbox root folder
$ git clone https://github.com/ztombol/bats-assert test/system/libs/bats-assert
$ git clone https://github.com/ztombol/bats-support test/system/libs/bats-support
```
## Convention
- All tests that start with *Try to..* expect non-zero return value.
- All tests should follow the nomenclature: `[command]: <test description>...`
- When the test is expected to fail, start the test description with "Try
to..."
- When the test is to give a non obvious output, it should be put in parenthesis
at the end of the title
Examples:
* `@test "create: Create the default container"`
* `@test "rm: Try to remove a non-existent container"`
- All the tests start with a clean system (no images or containers) to make sure
that there are no dependencies between tests and they are really isolated. Use
the `setup()` and `teardown()` functions for that purpose.
## How to run the tests
Make sure you have `bats` and `podman` with `toolbox` installed on your system.
**Important**
Before you start the tests, you need to have present two images: the default
`fedora-toolbox` image for your version of Fedora and the `fedora-toolbox:29`
image.
Make sure you have `bats`, `podman` and `toolbox` installed on your system. And
have the test dependencies prepared.
- Enter the toolbox root folder
- Invoke command `bats ./test/system/` and the test suite should fire up
