> Complete move to Gherkin for implementation testing
> ---------------------------------------------------
>
> Key: TINKERPOP-3136
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3136
> Project: TinkerPop
> Issue Type: Improvement
> Components: test-suite
> Affects Versions: 3.7.3
> Reporter: Stephen Mallette
> Priority: Major
>
> TinkerPop is most of the way to testing Gremlin exclusively with Gherkin. By
> 4.0 that move should be complete with whatever deprecations necessary for
> Java tests along 3.x. Retain the Java test suite for embedded {{Graph}} tests
> that only make sense in that case.
> For 3.x - likely 3.8.x
> * Create {{ProcessEmbeddedSuite}} and deprecate {{ProcessLimitedSuite}} to
> make it clear what aspects of Gremlin are meant for embedded cases and
> Java/Groovy sugar only. Update provider documentation to reflect these
> changes and ensure Gherkin is clear as the primary test suite for Gremlin.
> * Drop {{MergeVertexTest}} and {{MergeEdgeTest}} as remaining tests in there
> seem to be covered by Gherkin already.
> * Drop {{SubgraphTest}} since it should be able to be converted to feature
> tests but will need to add a way to assert a {{Graph}} though. Ignore in
> languages that don't have {{{}Graph{}}}.
> * Drop {{TreeTest}} since it should be able to be converted to feature tests
> but will need to add a way to assert a {{Tree}} though. Ignore in languages
> that don't have {{{}Tree{}}}.
> * Implement Gherkin tests for {{match()}} - do a limited and simple set to
> minimally test the capability since that feature is a bit up in the air for
> 4.x. Retain {{MatchTest}} as it is for the embedded suite for now.
> * For {{{}ComplexTest{}}}:
> ** {{cap('m')}} from {{classicRecommendation}} so that it can be asserted in
> {{{}Recommendation.feature{}}}.
> *** Figure out a way to assert the {{coworkerSummary}} tests in Gherkin. We
> don't currently have a way to assert very complex {{{}Map{}}}. The basic test
> could be run multiple times to try to break up the results to fit with the
> assertion capabilities?
> ** Move {{playlistPths}} to {{Paths.feature}}
> ** Remove {{ComplexTest}} as all relevant tests will have been moved to
> Gherkin.
> * Remove {{PartitionStrategyProcessTest}} - seems to be covered in Gherkin at
> this point.
> * Convert {{TernaryBooleanLogicsTest}} to Gherkin - add it to the
> {{/semantics}} directory.
> * Remove all lambda based tests from Gherkin since they are not supported by
> gremlin-language. Ensure that they all exist in the embedded tests. Perhaps
> put them all in a {{LambdaStepTest}} and combine in other embedded tests
> there so that they are all in once place. Remove all infrastructure for
> processing lambdas in the Gherkin suite. Test lambdas in GLVs independently.
> For 4.x
> * Remove {{ProcessLimitedSuite}} in favor of {{ProcessEmbeddedSuite}}
> * Since {{Tree}} and {{Graph}} will be present in 4.x for all languages,
> ensure that test suites are updated in support of those assertions as these
> tests will have been skipped prior.
> h3. Open questions
> * Make a decision about {{profile()}} and {{explain()}} in terms of how they
> are tested. Leaning toward them remaining an embedded case as they have
> implementation specific output potentially
> * Examine "Given an unsupported test" definitions....can any be supported
> now? what do we do with those that cant?
> Note the linked JIRAs below as well.
