What does the 'specify' method do in ruby on rails? -


So I'm working through chapter 6 of Michael Hartl's tutorial and came to this code 

  description with "invalid password" (to do this: user_for_invalid_password) {found_user.authenticate ( "invalid")} {not_not eq user_for_invalid_password} specify {expect (user_for_invalid_password) .to be_false}

What does the last line do? Specifically, what does it specify? I did not find anything about it through Google

Specify just Nickname you < / p>

There may be more investigation

the last line simply do not or can check the false , if you supply an invalid password

c# - Showing a SelectedItem's Property -

Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
