* Turn cartotest Expectation into an interface * SupplyChain interface for Cartotest * Supply a set of supply chain file paths Can pass in ytt values as well * Split large file * Refactor replaceIfFound * Update cli suite expected locating * Change cartotesting workload to an interface * Turn Givens.Template into an interface * Rename interface * Rename supplychain interface * BlueprintParams as an interface * Move functions * Change method to function * Change BlueprintInputs into an interface * Blueprint Params and Inputs nested under MockSupplyChain * Move method * Change pointers on methods * Move functions * Turn SupplyChain into an interface implemented by mock and actual supply chains * Rename Expectations and Given * Rename SupplyChainFileSet * Add fields to supply chain set * Rename Expectation interface implementations * Rename Expectation fields * First passing actual supply chain test * Change specification of ytt file for cli cartotests * Nest template cli fields as they are in new template struct * Nest mockSupplyChain CLI fields * Nest metadata and givens in CLI info file * Test CLI tests with go test * Begin moving CLI TestCase Population to functions * CLI TestCase Population in function * Split cli-suite-builder file into suite and case * Rename variables * Refactor populate testCase template * Further refactor populate testCase template * Rename function * Even further refactor populate testCase template * populate TestCase SupplyChain function * Working cartotest cli with actual supply chain * Create Comparison Option Field * CompareOptions yields cmp.Options * Cartotest CLI uses compareOptions * Reorder yaml files * Lint * Cartotest CLI can leverage number conversion function * Simplify cartotest cli Deprecate the 'templates' command * Ensure targetResource references provided template * Simplify language Cartesting tests are Test rather than TemplateTestCase Similarly Suite rather than TemplateTestSuite * Convert Blueprint params/inputs to SupplyChain params/inputs
