func SetGlobalRandom
func SetGlobalRandom(t *testing.T, seed uint64)
SetGlobalRandom sets a global, deterministic cryptographic randomness source for the duration of test t. It affects crypto/rand, and all implicit sources of cryptographic randomness in the crypto/... packages.
SetGlobalRandom may be called multiple times in the same test to reset the random stream or change the seed.
Because SetGlobalRandom affects the whole process, it cannot be used in parallel tests or tests with parallel ancestors.
Note that the way cryptographic algorithms use randomness is generally not specified and may change over time. Thus, if a test expects a specific output from a cryptographic function, it may fail in the future even if it uses SetGlobalRandom.
SetGlobalRandom is not supported when building against the Go Cryptographic Module v1.0.0 (i.e. when crypto/fips140.Version returns "v1.0.0").
