Jasmine-Parameterized
=====================
[](https://travis-ci.org/paucls/jasmine-parameterized)
Parameterized unit tests for Jasmine.
## Installation
```
npm install jasmine-parameterized
```
## Usage
This library provides a convenient `cases` function to easily parameterized the execution of `it` spec functions.
## Examples
### Single parameter
``` ts
import { cases } from 'jasmine-parameterized';
describe('Customer', () => {
cases([
4,
14
])
.it('should be a child when aged 4 to 14 years', (age) => {
const customer = new Customer(age);
expect(customer.isChild()).toBe(true);
});
...
```
### Multiple parameters
``` ts
describe('Roman Numeral Converter', () => {
cases([
[1, 'I'],
[2, 'II'],
[3, 'III'],
[4, 'IV'],
[5, 'V'],
[6, 'VI']
])
.it('converts Arabic number to its equivalent Roman numeral', ([arabic, roman]) => {
expect(romanFor(arabic)).toBe(roman);
});
});
```
### Multiple named parameters
For complex cases or when we want to be more explicit.
``` ts
describe('Fibonacci Sequence', () => {
describe('First two numbers', () => {
cases([
{index: 0, expected: 0},
{index: 1, expected: 1}
])
.it('should be same as index', ({index, expected}) => {
expect(fibonacciNumber(index)).toEqual(expected);
});
});
describe('Third number on', () => {
cases([
{index: 2, expected: 1},
{index: 3, expected: 2},
{index: 5, expected: 5}
])
.it('should be the sum of previous two', ({index, expected}) => {
expect(fibonacciNumber(index)).toEqual(expected);
});
});
});
```
