Function TestInjectImport_SortedAcrossModules

imports_test.go:120–138

TestInjectImport_SortedAcrossModules pins the cross-module emission order: it must be alphabetical by module, not append order. Calling the mutations in reverse alphabetical order should still yield the same output.

(t *testing.T)

// it must be alphabetical by module, not append order. Calling the mutations
// in reverse alphabetical order should still yield the same output.
func TestInjectImport_SortedAcrossModules(t *testing.T) {
	t.Parallel()

	ts := loadTypescript(t)
	ts.ApplyMutations(
		config.InjectImport("zod", "z"),
		config.InjectTypeImport("./types", "Foo"),
	)
	output, err := ts.Serialize()
	require.NoError(t, err, "serialize")

	block := importBlock(t, output)
	typesIdx := strings.Index(block, `from "./types"`)
	zodIdx := strings.Index(block, `from "zod"`)
	require.GreaterOrEqual(t, typesIdx, 0, "./types import must appear")
	require.GreaterOrEqual(t, zodIdx, 0, "zod import must appear")
	require.Less(t, typesIdx, zodIdx,
		"imports must be sorted alphabetically by module")
}

// TestInjectSideEffectImport exercises the bare-import form, deduplication,
// and per-module placement against a clausal import for the same module.
