Make clipboard work even in headless mode

[asolntsev]

The problem

Clipboard in Selenide work only in headful mode.
We can make it work in headless mode as well by using JavaScript instead of java.awt.Toolkit.

To set clipboard content:

window.clipboardData.setData('key', 'value')

To get clipboard content:

window.clipboardData.getData('key')

NB! Method getData() asks for permission. Need to find the webdriver option to suppress this dialog.

I think it will help, it will accept all permissions
got it from browserstack

DesiredCapabilities caps = new DesiredCapabilities();
    // INIT CHROME OPTIONS
    ChromeOptions options = new ChromeOptions();
    Map<String, Object> prefs = new HashMap<String, Object>();
    Map<String, Object> profile = new HashMap<String, Object>();
    Map<String, Object> contentSettings = new HashMap<String, Object>();

    // SET CHROME OPTIONS
    // 0 - Default, 1 - Allow, 2 - Block
    contentSettings.put("notifications", 1);
    profile.put("managed_default_content_settings", contentSettings);
    prefs.put("profile", profile);
    options.setExperimentalOption("prefs", prefs);

    // SET CAPABILITY
    caps.setCapability(ChromeOptions.CAPABILITY, options);

@kachurinaa I haven't found any working solution for Firefox. :(
Probably it's possible with CDP?

Try to experiment with that

#---------------------------------------------------------------------------
# Prefs starting with "permissions."
#---------------------------------------------------------------------------

# 1-Accept, 2-Deny, Any other value: Accept
- name: permissions.default.image
  type: RelaxedAtomicUint32
  value: 1
  mirror: always

- name: permissions.delegation.enabled
  type: bool
  value: true
  mirror: always

- name: permissions.isolateBy.userContext
  type: RelaxedAtomicBool
  value: false
  mirror: always

- name: permissions.isolateBy.privateBrowsing
  type: RelaxedAtomicBool
  value: true
  mirror: always

or this

- name: dom.webnotifications.allowinsecure
  type: RelaxedAtomicBool
  value: false
  mirror: always

- name: dom.webnotifications.allowcrossoriginiframe
  type: RelaxedAtomicBool
  value: false
  mirror: always

- name: dom.webnotifications.enabled
  type: RelaxedAtomicBool
  value: true
  mirror: always

- name: dom.webnotifications.requireuserinteraction
  type: RelaxedAtomicBool
  value: true
  mirror: always

- name: dom.webnotifications.requireinteraction.enabled
  type: RelaxedAtomicBool
  value: @IS_NIGHTLY_BUILD@
  mirror: always

- name: dom.webnotifications.silent.enabled
  type: RelaxedAtomicBool
#if defined(MOZ_WIDGET_ANDROID)
  value: @IS_NIGHTLY_BUILD@
#else
  value: false
#endif
  mirror: always

like this

FirefoxProfile ffprofile = new FirefoxProfile();
ffprofile.setPreference("dom.webnotifications.enabled", false);
WebDriver driver = new FirefoxDriver(ffprofile);

@kachurinaa The permission is not the only problem. Firefox also says that navigator.clipboard or navigator.clipboard.readText is not defined.

[aakachurin]

@asolntsev
Type "about:config" url in ff and switch/add attrs like that
clipboard=true
Its new privacy policy
