New features and enhancements

• Introduce a new integration test framework (#1931, #2496, #3121, #3413 by @rodja, @ed2050, @MarcDelahousse, @codingpaula, @falkoschindler):
  • a new user fixture cuts away the browser and replaces it by a lightweight simulation entirely in Python; a test for a login page can now be written like this:

          async def test_login():
              await user.open('/')
              user.find('Username').type('user1')
              user.find('Password').type('pass1').trigger('keydown.enter')
              await user.should_see('Hello user1!')
              user.find('logout').click()
              await user.should_see('Log in')
    

  • a new ElementFilter allows to find and manipulate UI elements during tests and in production
  • a new pytest plugin allows to use both NiceGUI fixtures screen and user via pytest_plugins = ['nicegui.testing.plugin']
• Remove icecream dependency (#3439 by @falkoschindler)
• Provide tests for run.io_bound and run.cpu_bound (#2234 by @rodja, @falkoschindler)
