func NewStream ¶

func NewStream(t *testing.T, seed int64) *randomStream

NewStream returns a randomStream seeded from seed, for deterministic randomness in tests of random outputs, and for small property-based tests.

This API is deliberately awkward to prevent it from being used outside of tests.

The testing framework runs the tests in a file in series, unless you explicitly request otherwise with testing.T.Parallel(). So one such stream per file is enough, most of the time.
