urlopen errore [Errno 111] Connessione rifiutata per selenio python

Question

Ho provato a disconnettermi dalla pagina di test, ma c'è errore di connessione rifiutare quando do driver.find_element_by_xpath ("// a [@href = '/ logged/pages /user/logout.php '] "). click() Ho anche provato con linktext, o ActionChains, lo stesso errore. E succede qualche volta, non sempre, qualche commento?

messaggio di errore

Questo è un problema di connettività temporanea tra le associazioni linguistiche selenio e un server di selenio. Ciò può accadere più spesso se si utilizza un server Selenium remoto su una macchina diversa e soprattutto se si utilizza Internet. Ad esempio, abbiamo riscontrato questo tipo di errori durante l'utilizzo di server di selenio remoto su BrowserStack o Sauce Labs.

Poiché i collegamenti Python/Selenium non hanno un modo automatico di riprovare richieste/comandi JSON wire (JSON over HTTP), si è costretti a gestirlo nel codice. Ad esempio, se si tratta di test che si stanno eseguendo, un metodo comune per risolvere questi errori è eseguire i test falliti 3 volte e, solo se tutti e 3 i tentativi falliscono, segnalare un test non riuscito.
