Struct executor

graphql/resolve/resolver_error_test.go:35–53

Tests that result completion and GraphQL error propagation are working properly. All the tests work on a mocked json response, rather than a running Dgraph. It's better to mock the Dgraph client interface in these tests and have cases where one can directly see the json response and how it gets modi

// to see what the test is actually doing.

type executor struct {
	// existenceQueriesResp stores JSON response of the existence queries in case of Add
	// or Update mutations and is returned for every third Execute call.
	// counter is used to count how many times Execute function has been called.
	existenceQueriesResp string
	counter              int
	counterLock          sync.Mutex

	assigned             map[string]string
	result               map[string]interface{}

	queryTouched    uint64
	mutationTouched uint64

	// start reporting Dgraph fails at this point (0 = never fail, 1 = fail on
	// first request, 2 = succeed once and then fail on 2nd request, etc.)
