This merges the `node-8` branch. The heavy lift was by @Daniel15 with refactoring from me and a patch by @RedSparr0w.
* New API for registering services (#963)
* Disable Node 6 tests on node-8 branch (#1423)
* BaseService: Factor out methods _regex and _namedParamsForMatch (#1425)
- Adjust test grouping
- Rename data -> queryParams, text -> message
* BaseService tests: Use Chai (#1450)
* BaseService: make serviceData and badgeData explicit and declarative (#1451)
* fix isValidStyle test (#1544)
* Run tests in Node 9, not Node 6 (#1543)
These tests should fail if something is accidentally changed that affects the SVG or JSON files. In the case of deliberate changes, we can update the snapshots.
* remove newlines from datauri
* update test, remove decode
* support multiline datauris
* replace whitespace before checking isDataUri
removed multiline support from regex
* prependPrefix set default as empty string
* update
* add dynamic xml badge support
* add tests
* dynamic badge add tests for query param
* remove try catch
* use `checkErrorResponse()`
* update tests
* [dynamic json] add test for multiple items
* Rebase, [dynamic xml] Add support for multiple items
* 404 response -> resource not found
* multiple results test less greedy regex
still alot of room for improvement to this test
* update dynamic badge gen
* add dynamic xml gen tests
* update tests id & path
* datalist -> select
* uri -> url
kept support for uri, incase of any already existing badges.
* split dynamic gen uri
* update query placeholder
