// TestAutoImportSymlinkedMonorepoGranularUpdate verifies that when a file in a symlinked
|
|
// project reference is edited, the auto-import index is updated efficiently via granular
|
|
// updates rather than rebuilding the entire node_modules bucket.
|
|
//
|
|
// Scenario:
|
|
// - project-a references project-b via project references (tsconfig)
|
|
// - project-b is symlinked into project-a's node_modules
|
|
// - Initially, project-b exports projectBValue
|
|
// - We get completions in project-a (builds the initial index)
|
|
// - We edit project-b to add a new export (newlyAddedFunction)
|
|
// - We get completions again in project-a
|
|
// - The new export should be available, proving the granular update worked
