Ruby code to setup a new TDD project

GitHub actions

Initial setup of a #Ruby project that uses RSpec for TDDing & guard to automatically run the unit tests when the file system changes.

I created this, while working on J. B. Rainsberger's (@jbrains) "The World's Best Intro to TDD" online course ➙ https://online-training.jbrains.ca/p/wbitdd-01

How to use it

Inside the directory of this repository, run

```bash
ruby bin/new_tdd_project.rb <new_project_name>
```

What it does

1. Checks that one argument is passed in: the name of a folder to create the new project in
2. Checks that this folder does not yet exist (and exits with an error message otherwise)
3. Create the new folder (and possibly sub folders) as a sibling of the tdd-setup project (this one)
4. Copies the following files & folders to he newly created one:
   • lib
   • spec
   • Gemfile
   • Guardfile
   • Rakefile
5. Lists the newly created files & folders
6. Sets put a new git repo (running git init in the new folder)
7. Runs bundle install in that folder

Suggested steps after creating the setup

• Go into the newly created project directory

• Probably run

  bundle exec rake

  to see that RSpec can be run via Rake You should get output similar to this:

  > bundle exec rake
   # Out put informing about the version manager, RSpec, and Ruby versions used
   
   Replace with real expectation
     actually test something useful
  
   Finished in 0.00205 seconds (files took 0.09764 seconds to load)
   1 example, 0 failures

• Running rspec without rake should also work fine:

   bundle exec rspec

• At least on macOS, using Guard should also work:

  bundle exec guard
  
  > bundle exec guard
  13:05:36 - INFO - Guard::RSpec is running
  13:05:36 - INFO - Running all specs
  
  Replace with real expectation
    actually test something useful
  
  Finished in 0.0017 seconds (files took 0.09278 seconds to load)
  1 example, 0 failures

  In addition to the output on the command line you should also get a notification on the screen, that looks like this:
