shouldHaveSameSizeAs :: HasCallStack => [a] -> Assertion [a]

assert if given list has same length as expected list

 assertThat [1..10] $ shouldHaveSameSizeAs [0..10]

shouldHaveSizeLowerOrEqual :: HasCallStack => Int -> Assertion [a]

verify if the given list has a length lower or equal to expected value

 assertThat [1..10] $ shouldHaveSizeLowerOrEqual 10

shouldStartWith :: (Eq a, Show a, HasCallStack) => [a] -> Assertion [a]

verify if the given list has expected prefix

 assertThat [1..10] $ shouldStartWith [0..4]

shouldNotStartWith :: (Eq a, Show a, HasCallStack) => [a] -> Assertion [a]

verify if the given list does not start with prefix

 assertThat [1..10] $ shouldNotStartWith [1..4]

shouldBeSameAs :: (Eq a, HasCallStack, Show a) => [a] -> Assertion [a]

shouldContain :: (Eq a, HasCallStack, Show a) => a -> Assertion [a]

shouldNotContain :: (Eq a, HasCallStack, Show a) => a -> Assertion [a]

shouldHaveSameElements :: (HasCallStack, Eq a, Show a) => [a] -> Assertion [a]

verify if the given list contains same elements as expected list in any order

 assertThat [1..10] $ shouldNotStartWith [1..4]
