ui: Repo layer integration tests for methods that touch the API
Includes a `repo` test helper to make repetitive tasks easier, plus a
injectable reporter for sending performance metrics to a centralized metrics
system
Also noticed somewhere in the ember models that I'd like to improve, but left
for the moment to make sure I concentrate on one task at a time, more or less:
The tests currently asserts against the existing JSON tree, which doesn't
seem to be a very nice tree.
The work at hand here is to refactor what is there, so test for the not
nice tree to ensure we don't get any regression, and add a skipped test
so I can come back here later
* Add some tests to check the correct GET API endpoints are called
* Refactor adapters
1. Add integration tests for `urlFor...` and majority `handleResponse` methods
2. Refactor out `handleResponse` a little more into single/batch/boolean
methods
3. Move setting of the `Datacenter` property into the `handleResponse`
method, basically the same place that the uid is being set using the dc
parsed form the URL
4. Add some Errors for if you don't pass ids to certain `urlFor` methods
Previously `api-double` usage in ember would require a bunch of `fetch`
requests to pull in the 'api double', this had a number of disadvantages.
1. The doubles needed to be available via HTTP, which meant a short term
solution of rsyncing the double files over to `public` in order to be served
over HTTP. An alternative to that would have been figuring out how to serve
something straight from `node_modules`, which would have been preferable.
2. ember/testem would not serve dot files (so anything starting with a
., like `.config`. To solve this via ember/testem would have involved
digging in to understand how to enable the serving of dot files.
3. ember/testem automatically rewrote urls for non-existant files to
folders, i.e. adding a slash for you, so `/v1/connect/intentions` would
be rewritten to `/v1/connect/intentions/`. This is undesirable, and
solving this via ember/testem would have involved digging deep to
disable that.
Serving the files via HTTP has now changed. The double files are now
embedded into the HTML has 'embedded templates' that can be found by
using the url of the file and a simple `querySelector`. This of course
only happens during testing and means I can fully control the 'serving'
of the doubles now, so I can say goodbye to the need to move files
around, worry about the need to serve dotfiles and the undesirable
trailing slashes rewriting. Winner!
Find the files and embedding them is done using a straightforward
recursive-readdir-sync (the `content-for` functionality is a synchronous
api) as oppose to getting stuck into `broccoli`.
