Is flash[] value kept through action to action in integration tests?

I have an integration test that sets a flash value in action before redirect and reads it in the next action (the one that previous action redirects to):

test("some integration test") do   get("/one")   assert_equal(true, flash[:foo]) ## is set to true in this action   assert_response(:redirect)

  follow_redirect!

  assert_equal(true, flash[:foo]) ## has to be true in next action end

So flash[:foo] has to be "true" in the second action. Because it is set in the first one. But my test throws an error:

1) Failure: <true> expected but was <nil>.

My question is, are flash values kept in integration test? Does it have to be "true" here or the above behavior is correct?

The Rails guide has a clear explanation of the flash:

Yes, the flash message is available IN the following request, but not after it. My bet is that your assertion is happening after that next action has completed.

Take a look at the example in Section 5.2 in this guide:

    post_via_redirect "/login", :username => users(:avs).username,       :password => users(:avs).password     assert_equal '/welcome', path     assert_equal 'Welcome avs!', flash[:notice]

Notice there is no follow_redirect! before checking the flash. Your flash is getting destroyed before you can assert it.

Use flash.now[:notice] !!

Wouldn't that just make matters worse? flash.now makes the flash available in the current request. It does not make it persists across requests. Use flash.now when you want render the template directly without a new request. That's not the case here.
