  2. Run the command npm install in the root directory of this project (same as this README).
  3. Run npm update to update all the packages
  4. Run npm run build
  5. Download Android Studio from the website, installed it with virtual devices support.
  6. Create a virtual device using device manager in Android device, and installing firefox on your virtual device.
  7. Setting the environment variable to get adb work, type adb to check if it works.
  8. Setting environment variable ANDROID_HOME to where you installed your Android Studio, JAVA_HOME to your jdk
  9. npm install -g appium@next, this will install appium v2.x
  10. Run appium driver install uiautomator2, appium driver install chromium, appium driver install gecko, this will get you the required driver
  11. Download geckodriver from geckodriver download website, extra the downloaded file and add the path to your environment.

Usage

  1. Run the virtual devices through Android Studio Device Manager or through terminal
  2. Run Appium in the root directory. To do this, open up a new terminal and type appium --base-path /wd/hub
  3. Open another terminal and run the command node ./build/index.js --url <url_to_san> to scan the <url_to_san> and all of its first-level subpages. For example, try running the command node ./build/index.js --url https://jkumara.github.io/pong-wasm/ as this site contains WebAssembly.
  4. To scan a list of urls with the crawler, run the command node ./build/index.js --file <file_path> to read in the file at <file_path>. For example, to use the included file sites.txt, run the command node ./build/index.js --file sites.txt
  5. To generate visual analysis report, run python scripts/ScreenshotAnalysis.py

TroubleShooting

  1. If in the emulator device open the browser but never goto the url, shut down appium terminal, and run adb uninstall io.appium.uiautomator2.server and adb uninstall io.appium.uiautomator2.server.test, then relaunch appium
