+// Package testutil provides initalization for unit and integration tests.
+//
+// Configures logging, random number generators and other global state.
+// Typical usage in _test.go files:
+//
+// import "v.io/x/ref/test"
+// func TestMain(m *testing.M) {
+// test.Init()
+// os.Exit(m.Run())
+// }
+//
+// InitForTest can be used within test functions as a safe alternative
+// to v23.Init.
+//
+// func TestFoo(t *testing.T) {
+// ctx, shutdown := test.InitForTest()
+// defer shutdown()
+// ...
+// }
+package test
