TestU01
TestU01 is a software library, implemented in the ANSI C language, that offers a collection of utilities for the empirical statistical testing of uniform random number generators (RNGs).〔(The TestU01 web site ).〕 The library was first introduced in 2007, by Pierre L’Ecuyer and Richard Simard of the Université de Montréal.〔Pierre L’Ecuyer & Richard Simard (2007), "(TestU01: A Software Library in ANSI C for Empirical Testing of Random Number Generators )", ''ACM Transactions on Mathematical Software'', 33: 22.〕
The library implements several types of random number generators, including some proposed in the literature and some found in widely used software. It provides general implementations of the classical statistical tests for random number generators, as well as several others proposed in the literature, and some original ones. These tests can be applied to the generators predefined in the library, user-defined generators, and streams of random numbers stored in files. Specific tests suites for either sequences of uniform random numbers in () or bit sequences are also available. Basic tools for plotting vectors of points produced by generators are provided as well.
== History ==
An initial battery of statistical tests for uniform RNGs was offered by the 1969 first edition of ''The Art of Computer Programming'', by Donald Knuth. In testing of RNGs, Knuth's tests were supplanted by George Marsaglia's (1996) Diehard tests, which consisted of fifteen different tests. The inability to modify the test parameters or add new tests led to the development of the TestU01 library.
