hspec-slow

Track and display slow specs in Hspec runs.

Example spec

main :: IO ()
main = do
  conf <- configure 1 -- Track specs that take longer than 1s
  timedHspec conf $ \it ->
    describe "Main" $ do
      it "should foo" $ do
        threadDelay 3000000
        1 `shouldBe` 1
      it "should bar" $ do
        threadDelay 1000
        1 `shouldBe` 1
      it "should baz" $ do
        threadDelay 4000000
        1 `shouldBe` 1

Example Output

Main
  should foo
  should bar
  should baz
Slow examples:
3.002925s: should foo
4.006186s: should baz
