A tiny module for running simple unit tests.

npm install --save horsea

const test = require('horsea');

const square = num => num * num;

test.block('When using the "square" function', () => {
  test.assert(square(4) === 16, 'The return value should be the square of the input value');
});

test.end();

$ node square.test.js 

When using the "square" function:

    PASS The return value should be the square of the input value

1 tests passed
0 tests failed

You always need to use require('horsea') in test files.
You can run the tests by usual node means (require('test-file.js') or node test-file.js).

Defines a new block of test assertions. The provided message is used as a block header.
This is mainly used as a way to neatly format output.

{String} message - The block header to display. {Function} func - A function containing test assertions to run.

If expression is truthy, the word "PASS" is printed, else the word "FAIL" is printed. The message provided is then displayed immediately afterwards.

{Mixed} expression - An expression to evaluate for "truthiness".
{String} message - A message to display.

Signals the end of the test and prints the total number of failing and passed tests. Takes no arguments.
