Jest was in the plugin array of the ESLint configuration, but no rules
were enabled. So ESLint hasn't checked any Jest rules yet.
So I activated the recommended Jest rules and added a few more. Then I
fixed the issues (mostly automatically). I have deactivated the rules
"jest/expect-expect" and "jest/no-done-callback" for the time being, as
they would have entailed major changes. I didn't want to make the PR too
big.
I'm not a Jest expert, but the changes so far look good to me. What do
you think of that @khassel? 🙂
* Fix Matching patterns tests directories Grunt task of eslint
* Fix eslint errors in testsuite.
* Format one line per file in src section in Gruntfile.js
- separated tests into e2e and unit directories
- created configs directory structure to support test framework
- added/modified `npm run test`, `npm run test:unit` and `npm run test:e2e` to target all, unit and e2e tests respectively
- modified some of the test names to be more descriptive
New structure of the Test Suite has following directory tree:
```
tests
├── configs
│ ├── env.js
│ └── modules
│ ├── clock
│ │ ├── clock_12hr.js
│ │ ├── clock_24hr.js
│ │ └── clock_showPeriodUpper.js
│ └── helloworld
│ └── helloworld.js
├── e2e
│ ├── env_spec.js
│ └── modules
│ ├── clock_spec.js
│ └── helloworld_spec.js
└── unit
├── functions
│ └── cmp_versions_spec.js
└── global_vars

```
