Expecto
The Expecto library can be installed from NuGet:
PM> Install-Package Expecto
Expecto.Flip has a similar syntax to FsUnit.
Expecto is not part of FsUnit.
Syntax
With Expecto.Flip you can write your unit tests like this:
open Expecto.Flip.Expect
One object equals or does not equal another:
1 |> equal "1 is equal to 1." 1
1 |> notEqual "1 is not equal to 2." 2
One comparable value greater or smaller than another:
(11, 10) |> isGreaterThan "11 is greater than 10."
(10, 11) |> isLessThan "10 is less than 11."
& more operators:
true |> isTrue "Value is true."
false |> isFalse "Value is false."
"" |> isEmpty
"Foobar" |> isNotEmpty "Value is not empty."
None |> isNone "Value is None."
{1 .. 10} |> contains "Seq 1 to 10 contains 4." 4
All operators are listed here: Expecto.Flip.Expect
