Function TestUpdateWithNoRepo

pkg/downloader/manager_test.go:374–438

TestUpdateWithNoRepo is for the case of a dependency that has no repo listed. This happens when the dependency is in the charts directory and does not need to be fetched.

(t *testing.T)

// This happens when the dependency is in the charts directory and does not need
// to be fetched.
