#################################### README ####################################
"""
The tests are written in a declarative style:
Each case has an entry in the `path_finding_cases` object
The key translates to a `suite(key, {...})`
The `{...}` passed in is compiled into a setup/teardown for the `ledger` and
into a bunch of `test` invokations for the `paths_expected`
- aliases are used throughout for easier reading
- test account addresses will be created `on the fly`
no need to declare in testconfig.js
debugged responses from the server substitute addresses for aliases
- The fixtures are setup just once for each ledger, multiple path finding
tests can be executed
- `paths_expected` top level keys are group names
2nd level keys are path test declarations
test declaration keys can be suffixed meaningfully with
`_skip`
`_only`
test declaration values can set
debug: true
Will dump the path declaration and
translated request and subsequent response
- hops in `alternatives[*][paths][*]` can be written in shorthand
eg.
ABC/G3|G3
get `ABC/G3` through `G3`
ABC/M1|M1
get `ABC/M1` through `M1`
XRP|$
get `XRP` through `$`
$ signifies an order book rather than account
------------------------------------------------------------------------------
Tests can be written in the 'path-tests-json.js' file in same directory # <--
