Looks great! I have some suggestions but I'll leave it up to you to decide to implement or not.

src/test_utils/stub_mapper.js

+  let stubbedMapper = Private(MapperService);
+
+  sinon.stub(stubbedMapper, 'getFieldsForIndexPattern', function () {
+    return Promise.resolve(mockLogstashFields.filter((field) => { return field.scripted === false; }));


This can be slightly simplified:

return Promise.resolve(mockLogstashFields.filter(field => field.scripted === false));

Nice! & done.

src/ui/public/courier/__tests__/saved_object.js

+    let savedObject = {};
+    savedObjectFactory.call(savedObject, config);
+    return savedObject;
+  }


Minor nit: can we move these functions above the beforeEach? That way all of the "helper" vars and functions are defined before the mocha-specific beforeEach and define calls.

indeed, done!

cjcenizal · 2016-11-21T20:29:38Z

src/ui/public/courier/__tests__/saved_object.js

+        });
+      });
+
+      it('applied to source if an id is given', function () {


Can we add a few more assertions:

If id is provided, it's available as an id property on the savedObject instance.

If it's 0, it's interpreted as undefined.

If it's false, it's interpreted as undefined.

If it's null, it's interpreted as undefined.

If it's not provided, it defaults to undefined.

I'm just thinking we should document this (kinda odd) behavior in case anything depends on it.

cjcenizal · 2016-11-21T20:32:41Z

src/ui/public/courier/__tests__/saved_object.js

+      });
+    });
+
+    it('searchSource creates index when true', function () {


Can we create an assertion for when it's false?

describe('searchSource', () => { describe('when true, blah blah', () => { }); describe('when false, blah blah', () => { }); });

src/ui/public/courier/__tests__/saved_object.js

+      });
+    });
+  });
+});


Might also be good to add tests for other instance methods applyESResp, serialize, save, saveSource, destroy, and delete. What do you think?

Added one for applyESResp. Save I'd prefer to get in the save/rename flow since I know what to test there. As for the others, it feels like I'd just be testing implementation details as opposed to expected results, so at least with my current understanding of this code, it doesn't seem super beneficial. (e.g. for delete, I could test that es.delete is called, but not that the item is actually deleted).

src/ui/public/courier/__tests__/saved_object.js

+import { stubMapper } from 'test_utils/stub_mapper';
+import IndexPatternFactory from 'ui/index_patterns/_index_pattern';
+
+describe('Saved Object', function () {


This relates to #9161, I've seen a number of tests that would've used 'ui/courier/saved_object' for the describe, but I've also seen a number of tests do it this way. I'm not sure which way is preferred.

I don't know if there is a rule for this, but I think I prefer not specifying the path, otherwise you'd have to update the test if you move the file and I could see that easily being forgotten.

src/ui/public/courier/__tests__/saved_object.js

+  let esStub;
+
+  beforeEach(ngMock.module('kibana'));
+  beforeEach(ngMock.inject(function ($injector, Private) {


Is there a reason we're injecting $injector and then using $injector.get('es') below as opposed to just injecting es?

fetch.js does something similar to what I did, getting es from the injector. Happy to write it another way that makes more sense but I'm not sure how to 'just inject es'. If you can give me a little code snippet to explain your suggestion I can add it.

I think you could change this to the following:

beforeEach(ngMock.inject(function (es, Private) { SavedObject = Private(SavedObjectFactory); IndexPattern = Private(IndexPatternFactory); esStub = es; mockEsService(); stubMapper(Private); }));

ah, awesome, done!

kobelb · 2016-11-22T14:48:01Z

src/ui/public/courier/__tests__/saved_object.js

+
+  beforeEach(ngMock.module('kibana'));
+  beforeEach(ngMock.inject(function ($injector, Private) {
+    savedObjectFactory = Private(SavedObjectFactory);


I feel like I've more commonly seen this being imported as SavedObject and then used as a constructor in the createSavedObject below.

So instead of having:

let savedObject = {}; savedObjectFactory.call(savedObject, config); return savedObject;

it'd become:

return new SavedObject(config);

Ah, much better. I was confused with the factory and private stuff, making this overly complicated. Done!

src/ui/public/courier/__tests__/saved_object.js

+  describe ('config', function () {
+
+    it('afterESResp is called', function () {
+      let afterESRespCallback = sinon.spy();


Throughout the tests, there's an inconsistent usage of const and let. There appears to be a pattern that generally let is used when an object will be 'mutated'; however, that's not the difference between const/let in javascript. let allows a reference to be reassigned per https://github.com/airbnb/javascript#references--prefer-const

Learn something new every day. Changed to const!
