#Arrow

##Overview

Arrow is a test framework designed to promote test-driven JavaScript development. Arrow provides a consistent test creation and execution environment for both Developers and Quality Engineers.

Arrow aims to completely remove the line between development’s Unit tests, and Functional and Integration tests by providing a uniform way to create and execute both.

Arrow itself is a thin, extensible layer that marries JavaScript, NodeJS and Selenium. Arrow allows you to write tests using YUI-Test and execute those tests using NodeJS or Selenium. Additionally, Arrow provides a rich mechanism for building, organizing and executing test and test scenarios.

##Examples

Below are some examples to help you get started.

###Unit test:

arrow --lib=../src/greeter.js test-unit.js

###Unit test with a mock page:

arrow --page=testMock.html --lib=./test-lib.js test-unit.js

###Unit test with --shareLibPath to replace --lib: Please note that the folder passed to --shareLibPath need follow layout convention as described in arrow cookbook "Arrow In-Depth"

arrow --page=testMock.html --shareLibPath=../ test-unit.js

###Unit test with selenium:

arrow --page=testMock.html --lib=./test-lib.js --driver=selenium test-unit.js

###Integration test:

arrow --page=http://www.hostname.com/testpage --lib=./test-lib.js test-int.js

###Integration test:

arrow --page=http://www.hostname.com/testpage --lib=./test-lib.js --driver=selenium test-int.js

###Custom controller:

arrow --controller=custom-controller.js --driver=selenium
