webdriver

A simple (features as needs arise) Clojure wrapper of Selenium Webdriver

Usage

If you want to use the truly headless/recording environment, you'll need to be running a linux host with xvfb and ffmpeg installed.
sudo apt-get install ffmpeg xvfb
sudo pacman -S ffmpeg xorg-server-xvfb

Example

Assuming you're in a repl (lein repl)...

Import the core namespace:

(use 'webdriver.core)

Create a driver object

Chrome:

• (def driver (create-driver {:driver-type :chrome}))

Firefox:

• (def driver (create-driver {:driver-type :firefox}))

Specific driver versions can also be passed to :chrome or :firefox versions

• (def driver (create-driver {:driver-type :chrome :version "81.0.4044.138"}))

Headless:

• (def driver (create-driver {:driver-type :chrome :driver-args ["--headless"]}))

Xvfb (Linux only with xvfb installed)

(require '[webdriver.screen :as scr])
(def screen (scr/start-screen)) ;this is separate from driver so that we can have multiple drivers run in a single frame buffer
(def driver (create-driver {:driver-type :chrome :xvfb-port (:xvfb-port screen)}))

Now you can pass the driver object into the other functions in core to manipulate it.

(to driver "https://google.com")
(set-element driver :name "q" "silly memes")
(click (wait-for-element driver :xpath "//input[@value = 'Google Search'][1]"))

From functional code:

(with-webdriver [driver :driver-type :chrome :driver-args ["--headless"]]
  (to driver "https://google.com")
  (set-element driver :name "q" "silly memes")
  (click (wait-for-element driver :xpath "//input[@value = 'Google Search'][1]")))

If you want a truly headless environment that doesn't have the issues of geckodriver --headless or chromedriver --headless:

(scr/with-screen [screen]
  (with-webdriver [driver :driver-type :chrome :xvfb-port (:xvfb-port screen)]
    (to driver "https://google.com")
    (set-element driver :name "q" "silly memes")
    (click (wait-for-element driver :xpath "//input[@value = 'Google Search'][1]"))))

If you want to record that headless session:

(scr/with-recorded-screen [screen :vid-out "/tmp/webdriver.mp4"]
  (with-webdriver [driver :driver-type :chrome :xvfb-port (:xvfb-port screen)]
    (to driver "https://google.com")
    (set-element driver :name "q" "silly memes")
    (click (wait-for-element driver :xpath "//input[@value = 'Google Search'][1]"))))

etc...

core.clj contains functions to handle common browser tasks. You can either read through that or checkout tests/webdriver/core_test.clj for unit test examples.

Breaking changes:

• In webdriver 0.11.0, functions that use to return webdrivers now return maps with a WebDriver object at :driver. This means that some code that used java interop on driver objects will now be broken. Internally this has been updated. According to the unit tests, the functions in webdriver.core still work together properly.

; in webdriver 0.10.0 this would work
(def driver (create-driver {:driver-type :chrome}))
(.getVersion (.getCapabilities driver))
(driver-quit driver)

; in webdriver 0.11.0 you'll have to do it differently
(def driver (create-driver {:driver-type :chrome}))
(.getVersion (.getCapabilities (:driver driver))) ; notice (:driver driver) instead of just driver
(driver-quit driver)
