Simple Emscripten auto test with ChromeDriver

In this article, I will describe the implementation of running autotest for ChromeDriver of the Chrome browser, which runs the module autotest translated from C ++ using Emscripten, reads the console output and returns the result of the check.
First you need to install selenium, for python3-ubuntu this is done like this:


pip3 install selenium

Next, download ChromeDriver from the official site, put the chromedriver in / usr / local / bin for example, after which you can start implementing the autotest.
Below I will give the autotest code that launches the Chrome browser with the autotest page open on Emscripten, checks for the presence of the text “Window test succeded”:


import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

capabilities = DesiredCapabilities.CHROME
capabilities['goog:loggingPrefs'] = { 'browser':'ALL' }
driver = webdriver.Chrome()
driver.get("http://localhost/windowInitializeTest/indexFullscreen.html")

time.sleep(2)

exitCode = 1

for entry in driver.get_log('browser'):
    if entry["source"] == "console-api":
        message = entry["message"]
        if "Window test succeded" in message:
            print("Test succeded")
            exitCode = 0

driver.close()
exit(exitCode)

Save the test as main.py and run python3 main.py
