RandomizedTesting.Generators

v2.7.8

RandomizedTesting.Generators contains generators for random numbers, several forms of text (ASCII, Unicode, realistic Unicode, HTML-like, regular expression-like) as well providing methods to pick random selections from collections and arrays and even create randomly generated Regex classes. These features are implemented as simple low-level extension methods to for the Random class so there is very little to learn to quickly generate random data for your tests. Why would you want tests to have random data? This is to fill situations where it is not practical to test the entire range of values in a single test run, for example, with applications that analyze text. Tests can instead be designed to provide different input every time they run to catch edge cases that are difficult to test for. Generating random data also has many other purposes, such as quickly generating a set of text files to benchmark with without having to store several hundred MB worth of files (since the same random seed will always generate the same data).
