a custombutton should check some Logic and show a simple Messagebox.

in views i added:

<button string="Start Tests" type="object" name="start_test"/>


in the model i tried the following

@api.one
def start_test(self):
    #....
    #....
    return {
        'warning': {
            'title': 'Information',
            'message': 'Testmessage!'
        }
    }


how can i achiev to show a Messagebox after Buttonclick?

You won't be able to return a warning entry in a dict, because that style is intended to be used for onchange warnings. To solve it you have the following options:

1- Raise a Validation Exception like:

from odoo import exceptions
...
raise exceptions.ValidationError("Validation Message")

2- Create a wizard like form to show the message and return an action in the button to instruct Odoo to open that form from your wizard model.

return {
    'type': 'ir.actions.act_window',
    'res_model': model_name,
    'view_type': 'form',
    'view_mode': 'form',
    'views': [(view_id, 'form')],
    'target': 'new',
    'res_id': self.id,
    'context': dict(self._context),
}

 You could pass the value for a field in the wizard using the context to display the needed message, just set a 'default_'+ field_name entry in the context with the value
