Lets say  you re running test for creating todo  You can always run  that specific todo spec code using the file crete spec rb file as below         rspec spec features controller spec file name rb     Example      Creating  rspec spec features todos create spec rb    Editing   rspec spec features todos edit spec rb    Deleting  rspec spec features todos destroy spec rb   If you want to run all the specs in one single short      rspec    If you want to run all the specs in a specific controller user this     rspec spec feaures controller name    Example    rspec spec features todos   Hope it gives you more understanding

You can also use the actual text of the  e xample test case with -e    So for   it  shows the plane arrival time    you can use  rspec path to spec file rb -e  shows the plane arrival time    scripts spec path to spec file rb -e  shows the plane arrival time    no need for rake here

To run all of your rspec files  rspec  note  you must be in the root of your project   To run one rspec file  rspec  path to spec rb   note  replace  path to spec rb  with your path  Quotation marks optional   To run one rspec test from one file  rspec  path to spec rb 7   note   7 is the line number where the test starts

Alternatively  have a look at autotest   Running autotest in a command window will mean that the spec file will be executed whenever you save it  Also  it will be run whenever the file you are speccing is run   For instance  if you have a model spec file called person spec rb  and a model file that it is speccing called person rb  then whenever you save either of these files from your editor  the spec file will be executed

Although many great answers were written to this question  none of them uses the Rspec tags approach    I use tags to run one or more specs in different files -- only those related to my current development task   For example  I add the tag  dev  with the value  current    it  creates an user   dev   current do   user   create  user    expect user persisted   to be truthy end   then I run  bundle exec rspec   --tag dev current   Different tags values can be set in individual specs or groups

If you installed rspec as a plugin rather than as a gem  then you won t have the spec executable   At any rate  All you need to do is run the file using ruby  The rspec code is clever enough to run the tests for you   eg   ruby myclass spec rb

This question is an old one  but it shows up at the top of Google when searching for how to run a single test   I don t know if it s a recent addition  but to run a single test out of a spec you can do the following   rspec path to spec  lt line number gt    where -line number- is a line number that contains part of your test   For example  if you had a spec like   1   2  it  should be awesome  do 3    foo   3 4    foo should eq 3  5  end 6    Let s say it s saved in spec models foo spec rb   Then you would run   rspec spec models foo spec rb 2   and it would just run that one spec   In fact  that number could be anything from 2 to 5   Hope this helps

Ruby 1 9 2 and Rails 3 have an easy way to run one spec file      ruby -I spec spec models user spec rb   Explanation    ruby command tends to be faster than the rake command -I spec means  include the  spec  directory when looking for files  spec models user spec rb is the file we want to run

Or you can skip rake and use the  rspec  command   rspec path to spec file rb   In your case I think as long as your   spec db spec rb file includes the appropriate helpers  it should work fine    If you re using an older version of rspec it is   spec path to spec file rb

I was having trouble getting any of these examples to work  maybe because the post is old and the commands have changed   After some poking around I found this works   rspec spec models user spec rb  That will run just the single file and provides useful output in the terminal
