Simple behavior driven testing in Io.

Install

git clone https://github.com/benmills/willful.git
cd willful
io install.io

Write

doFile(System ioPath .. "/willful.io")
Foo := Object clone do( bar := method("bar"))

describe("Foo") do(
  it("Will bar", block(
    f := Foo clone
    f bar will == "bar"
    f bar will != "baz"
    f bar will beOk
  ))
)

Run

The willful command will look for any file with a name containing -test and attempt to run them. You can also explicitly tell it what to run by passing any number of files or directories.

$ willful foo-test.io
