Expecto aims to make it easy to test CLR based software; be it with unit tests, stress tests, regression tests or
property based tests. Expecto tests are parallel and async by default, so that you can use all your cores for
testing your software. This also opens up a new way of catching threading and memory issues for free using stress
testing.
With Expecto you write tests as values. Tests can be composed, reduced, filtered, repeated and passed as values, because
they are values. This gives the programmer a lot of leverage when writing tests. Setup and teardown are just simple
functions, no need for attributes.
Expecto comes with batteries included with an integrated test runner, but it's still open for extension due to its
compositional model.
Expecto comes with performance testing, making statistically sound performance comparison simple.
Expecto also provides a simple API for property based testing using FsCheck.
