Guard::Jstd provides autotest functionality for your test driven JavaScript development with JsTestDriver. This gem was inspired by the jstdutil gem and modeled after the Guard::RSpec gem.

From the command line:

$ gem install guard-jstd

Or in your Gemfile:

group :test do
  gem "guard-jstd"
end

Generate the suggested Guardfile with:

guard init jstd

See the Guard gem README for more information about using Guard.

By default, Guard::Jstd will attempt to start the JsTestDriver server. This is done as a forked process, so when you stop Guard with Ctrl-C, the Jstd server will also stop.

Ctrl-\ or Ctrl-Z will run all of your tests.

You can specify some configuration options by passing a block to Jstd.configure. This must appear after the 'guard "jstd"' definition in your Guardfile. An example configuration is given below.

guard "jstd" do
  # mappings here
end

Jstd.configure do |c|
  c.java_path = "~/my/path/JsTestDriver-1.3.2.jar"
  c.browser_paths = "\`which open\`"
  c.jstd_config_path = 'someJsTestDriver.conf'
  c.start_server = false
  c.capture_browser = false    # false is the default
end

If you have a "$JSTESTDRIVER_HOME" environment variable set on your system, Jstd will automatically look for your JsTestDriver .jar file there. Otherwise, you have to configure the path with "c.java_path".

On start up, Jstd will attempt to start the JsTestDriver server. You can prevent this with "c.start_server = false". The server_port is determined from your JsTestDriver configuration file. If this file does not exist, then the default port is 4224. If you really want Jstd to start the server in a specified port, then you can do that with "c.server_port = 1234".

If you set "c.capture_browser = true", then Jstd will attempt to capture the browser(s) defined in "c.browser_path" when the server is started. Otherwise, you have to manually capture browsers after the server starts.

The default JsTestDriver configuration file name is 'jsTestDriver.conf'. If you are using something else, then use "c.jstd_config_path".

Information about setting up JsTestDriver on your system can be found here or on the JsTestDriver homepage.

If you want to use CoffeeScript in your development, add the guard-coffeescript gem. To avoid conflict with Guard::CoffeeScript, Ctrl-\ is disabled for Guard::Jstd. Use Ctrl-Z instead to run all tests.
