Erreur Selenium WebDriver: identifiant de session non valide

J'utilise Selenium WebDriver et Chrome pour effectuer des tests de fonctionnalités dans mon application. J'ai déjà configuré avec succès plusieurs applications Rails avec rspec, capybara et Selenium, mais je peux ne comprends pas pourquoi celui-ci ne fonctionne pas.

Voici le problème: lorsque j'exécute les tests de fonctionnalité pour la première fois, cela fonctionne comme prévu. Cependant, si je l'exécute une deuxième fois, Selenium se bloque avec le message suivant:

Selenium :: WebDriver :: Error :: NoSuchDriverError: identifiant de session non valide (Informations sur le pilote: chromedriver = 74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729 @ {# 29}), plateforme = Mac OS X 10.14.3 x86_64)

Je pourrais ajouter que les tests de fonctionnalité fonctionnent parfaitement dans d'autres applications, il ne s'agit donc pas d'un problème de compatibilité Chrome/chromedriver.

J'y travaille depuis des jours maintenant et je n'arrive pas à comprendre ce qui se passe

Voici ma config:

  • Sélénium-Webdriver (3.141.0)
  • capybara (2.7.1)
  • Chrome 74 et chromedriver 74.0.3729.6

    chromeOptions: { args: %w(headless disable-gpu) }
  )

  Capybara::Selenium::Driver.new app,
    browser: :chrome,
    desired_capabilities: capabilities
end

Capybara.javascript_driver = :headless_chrome

Chromedriver réutilise le même identifiant de session à plusieurs reprises au cours des tests. C'est pourquoi la première fois, les tests réussissent, mais si je recommence, chromedriver utilisera exactement le même identifiant de session qui est à mon avis la cause du problème. J'ai enregistré les actions de Selenium, et cela envoie DELETE donc je ne comprends pas.

J'ai trouvé ce qui n'allait pas.

Nous utilisons une bibliothèque pour mettre en cache la réponse api pendant le test après leur première création.

Le problème est que le pilote envoie une demande pour obtenir un identifiant de session. C'est pourquoi la première fois, les tests ont réussi. La bibliothèque a mis en cache la réponse du pilote qui avait à chaque fois le même identifiant de session, d'où l'erreur de Chrome.

Si vous utilisez de telles bibliothèques (VCR, ephemeral_response) et obtenez une erreur similaire, c'est quelque chose que vous voudrez peut-être étudier

La première chose que je remarque, c'est que vous utilisez une version de 3 ans de Capybara avec de nouvelles versions de Selenium-webdriver, Chrome et chromedriver. Puisque Selenium-webdriver ne suit pas SemVer s'attendre à ce que ceux-ci fonctionnent correctement ensemble est un tronçon. Vous souhaitez probablement mettre à niveau Capybara.

Cette erreur est souvent due à des problèmes de ressources avec Chrome. Étant donné que vous semblez fonctionner sur MacOS, ce n'est pas aussi probable que si vous l'exécutiez dans des conteneurs. Mais cela ne ferait pas de mal d'essayer d'ajouter le disable-dev-shm-usage chrome option, et/ou définition de la taille de la fenêtre plus petite pour voir si l'erreur disparaît. Vous pouvez également essayer de redémarrer.

Au-delà, quelques autres potentiels sont

  1. Vous avez enregistré un bloc après qui a déjà fermé la session - commentez le bloc après et voyez si le problème disparaît

  2. Un bogue dans chromedriver 74 (dont quelques-uns ont été signalés - https://bugs.chromium.org/p/chromedriver/issues/detail?id=2885 , etc) - essayez de revenir à chrome et chromedriver 73 pour voir si le problème disparaît

J'ai eu cette erreur aujourd'hui et ce qui a fonctionné pour moi a été de rétrograder la version chromedriver de la dernière à la version chrome que j'ai installée sur ma machine.
