Here you can find the slides of the presenation in different formats plus the implementation of the code kata.
## The String Calculator Code Kata
The repository contains the implementation of the code kata until the 2nd bullet.
Practicing TDD on the [string calculator code kata](http://osherove.com/tdd-kata-1/).
### Rules and specs
Before you start:
* Try not to read ahead.
* Do one task at a time. The trick is to learn to work incrementally.
* Make sure you only test for correct inputs. there is no need to test for invalid inputs for this kata
#### String Calculator Spec
* Create a simple String calculator with a method int Add(string numbers)
* The method can take 0, 1 or 2 numbers, and will return their sum (for an empty string it will return 0) for example ```""``` or ```"1"``` or ```"1,2"```
* Start with the simplest test case of an empty string and move to 1 and two numbers
* Remember to solve things as simply as possible so that you force yourself to write tests you did not think about
* Remember to refactor after each passing test
* Allow the Add method to handle an unknown amount of numbers
* Allow the Add method to handle new lines between numbers (instead of commas).
* the following input is ok: ```"1\n2,3"``` (will equal 6)
* the following input is NOT ok: ```"1,\n"``` (not need to prove it - just clarifying)
* Support different delimiters
* to change a delimiter, the beginning of the string will contain a separate line that looks like this: ```"//[delimiter]\n[numbers…]"``` for example ```"//;\n1;2"``` should return three where the default delimiter is ';' .
* the first line is optional. all existing scenarios should still be supported
* Calling Add with a negative number will throw an exception "negatives not allowed" - and the negative that was passed.if there are multiple negatives, show all of them in the exception message.
Stop here if you are a beginner. Continue if you can finish the steps so far in less than 30 minutes.
* Numbers bigger than 1000 should be ignored, so adding 2 + 1001 = 2
* Delimiters can be of any length with the following format: ```"//[delimiter]\n"``` for example: ```"//[***]\n1***2***3"``` should return 6
* Allow multiple delimiters like this: ```"//[delim1][delim2]\n"``` for example ```"//[*][%]\n1*2%3"``` should return 6.
* make sure you can also handle multiple delimiters with length longer than one char
## Getting Started
You need an installation of node.js to run the project. I suggest to install one using [nvm](https://github.com/creationix/nvm).
After the installation of node, running the following command while on the project root directory should get you started.
```javascript
npm install
```
Grunt is used for automation and the following tasks are present:
* `grunt jshint`: Static analysis of the project code with [jshint](https://github.com/jshint/jshint). In order to run this step you must do a ```npm install -g jshint``` first.
* `grunt jscs`: Style check of the project code with [jscs](https://github.com/jscs-dev/node-jscs). It uses the [google code style](https://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml) as a preset.
* `grunt mochaTest`: Execute the test suite of the project.
* `grunt`: Run all of the above. When one of the tools returns an error, it will stop.
