It works with any assertion library that throws and AssertionError from built in the assert module or an error the actual or expected values set.

The API Documention

Installation

  npm install sanna

Usage

In a tests file tests/first.test.js

const { suite, test } = require('sanna');
const assert = require('assert')

const s = suite('True values')
s('Test if true realy is true', () => {
  assert(true)
});

const assertIsTrue = (actual) => {
  if (actual !== true) {
    throw new assert.AssertionError({
      message: 'Asserted value is not true',
      actual,
      expected: true,
    });
  }
};

s('Home maied assertion testing if a value is true', () => {
  assert(true)
});

Running

Running tests can be done in 2 ways.

1. By running the sanna executable installed by the module it by default looks for *.test.js files in the tests folder.

sanna tests/first.test.js

2. run the tests files directly with node.js mostly useful for running an single test file at a time

node tests/first.test.js

On test success

Print out progress dots and success stats.

$ sanna tests/test.js ....

4 tests passed

On test failure

Prints out a nifty error report include

• The test file and line number of the test or hook that failed
• The error and it's stack-trace
• A diff or the AssertionError actual and expected values
• Failed/Pass stats

$ sanna tests/first.test.js
