Obtenir l'erreur "Échec: Fn n'est pas une fonction" quand essayer d'automatiser e2e pour une page de connexion

Question

J'essaye d'automatiser et de ruminer un simple formulaire de registre mais j'obtiens une erreur disant "Échec: Fn n'est pas une fonction". Voici mon code

describe('Locator testing by model', function(){ 

    it('automate user register form', function(){ 
     browser.get('http://www.way2automation.com/angularjs-protractor/registeration/#/login'); 
     element(by.model('Auth.user.name')).sendKeys('angular'); 
     element(by.model('Auth.user.password')).sendKeys('password'); 
     element(by.model('model[options.key]')).sendKeys('zafaque'); 
     element(by.buttonText('Login')).click(); 
     browser.wait(3000); 
    }); 
}); 

ci-dessous est le détail d'erreur

Answer 1

Vous utilisez browser.wait() de manière incorrecte. Reportez-vous à la documentation officielle pour l'utilisation correcte here

browser.wait() accepte params dans l'ordre ci-dessous

premier argument est une condition qui peut être une fonction ou un webdriver.promise.Promise ou attendu Le deuxième argument de la condition est le délai d'expiration

Mais vous passez le délai d'attente comme premier argument. Incase vous attendre juste une attente sans condition - Il suffit d'utiliser browser.sleep(3000)
