Documentation for result of test-var-query

[marcomorain]

I've been working on improving the test infrastructure in Calva, and I'm currently trying to integrate closer with Cider's test middleware.

There is no documentation that I can find for the shape of the result returned from test-var-query.

Returns

:results A map of test run data.
:status Either done or indication of an error

Where is the best place to find out what is returned? Are there docs somewhere, or is the code the best place to look?

Probably I'd look into cider.nrepl.middleware.test + cider.nrepl.middleware.test-test directly

For example this is the init state:

cider-nrepl/src/cider/nrepl/middleware/test.clj

Lines 45 to 46 in 7dd4e1b

	(reset! current-report {:summary {:ns 0 :var 0 :test 0 :pass 0 :fail 0 :error 0}
	:results {} :testing-ns nil :gen-input nil}))

Hope it helps!

@marcomorain I guess we never documented this properly, so we should change this. The tests are good starting point and I'm thinking it'd be nice to have more documentation about each of the ops, besides the basic one generated from the descriptor. E.g. something like https://nrepl.org/nrepl/0.8/usage/misc.html#code-completion

I've come across a strange issue related to this:

<- received
{
  'gen-input': [],
  id: '13',
  results: {
    'sample-project.core-test': {
      'some-new-var': [
        {
          actual: '(2)\n',
          context: [],     <---- array, not a string
          diffs: [ [Array] ],
          expected: '1\n',
          file: 'core_test.clj',
          index: 0,
          line: 8,
          message: '',
          ns: 'sample-project.core-test',
          type: 'fail',
          var: 'some-new-var'
        }
      ]
    }
  },
  session: '7cc0b066-a90a-4285-b455-a99f84fc6ce2',
  summary: { error: 0, fail: 1, ns: 1, pass: 0, test: 1, var: 1 },
  'testing-ns': 'sample-project.core-test'
}

When a test is run that doesn't contain a testing form, the context data returned from cider-nrepl is an empty array, rather than a string or null, which is what I would expect.

[marcomorain]

When there is a testing form, context is a string:

<- received
{
  'gen-input': [],
  id: '17',
  results: {
    'sample-project.core-test': {
      'this-will-fail': [
        {
          actual: '(a)\n',
          context: 'that something works',   <------- string
          diffs: [ [Array] ],
          expected: 'a\n',
          file: 'core_test.clj',
          index: 0,
          line: 13,
          message: '',
          ns: 'sample-project.core-test',
          type: 'fail',
          var: 'this-will-fail'
        },
        {
          context: 'that something works',  <------- string
          index: 1,
          message: '',
          ns: 'sample-project.core-test',
          type: 'pass',
          var: 'this-will-fail'
        }
      ]
    }
  },
  session: '7cc0b066-a90a-4285-b455-a99f84fc6ce2',
  summary: { error: 0, fail: 1, ns: 1, pass: 1, test: 2, var: 1 },
