[Testing] Selenium webdriver + Minitest + SQLite3

Hi there,

I have a rails application (version 3.2.22). And now I’m creating functional tests through browser using Selenium Webdriver(for browser interaction) and Minitest (to validate).

Before running my test script (that fills a form and submits), I launch the rails server in order to selenium access the application.

Problem: When the selenium ‘clicks’ on the submit button, the server raises the following error related to Sqlite:

SQLite3::BusyException: database is locked: commit transaction

I have tried a lot of things that the stack overflow and other articles suggested, however, none has worked so far.

So, do you have any ideia why htis is happening and how to fix this?

Thank You in advance,

João Bordalo

You've confirmed this succeeds when you perform this same operation
manually? I would wonder if Selenium is somehow generating two click
events, but that's a WAG.

Is there a stack trace you can post?

I have tried it manually and It works as it is supposed to ( the form is submitted currently to database).

No, it is the server that raises the error, not the selenium script

? Where are you seeing the error? If it's server-generated then I'd
expect *something* in the logs, hopefully including a stacktrace.

Thank you for your attempts.
I noticed that i was trying to read DB on my selenium script while server was trying tu write on the same DB.
Removed those lines and it is working fine.
