Fable.Jester

Fable bindings for jest and friends for delightful Fable testing:

• fast-check
• jest-dom
• react-testing-library
• user-event
• testing-playground

A quick look:

Jest.describe("my tests", fun () ->
    Jest.test("water is wet", fun () ->
        Jest.expect("test").toBe("test")
        Jest.expect("test").not.toBe("somethingElse")
        Jest.expect("hi").toHaveLength(2)
        Jest.expect("hi").not.toHaveLength(3)
    )
    Jest.test.prop("Is positive", Arbitrary.ConstrainedDefaults.integer(1,100), fun i ->
        Jest.expect(i).toBeGreaterThan(0)
    )
)
