qunit-assert-compare

A QUnit plugin for asserting numerical comparisons like greater than, less than, etc.

QUnit numerical comparison assertion plugin

This plugin for QUnit adds a handful of custom assertion methods to test for various numerical comparison situations:

• eq: equal to
• neq: not equal to
• lt: less than
• lte: less than or equal to
• gt: greater than
• gte: greater than or equal to
• compare: sorting-style comparisons

Usage

assert.eq(num1, num2, message);
assert.neq(num1, num2, message);
assert.lt(num1, num2, message);
assert.lte(num1, num2, message);
assert.gt(num1, num2, message);
assert.gte(num1, num2, message);
assert.compare(num1, num2, expected, message);

Where:

• num1: The lefthand operand
• num2: The righthand operand
• message: Optional message, same as for other assertions
• expected: [ONLY used for assert.compare!] A sorting-style return value for the numerical comparison:
  • -1 (less than)
  • 0 (equal to)
  • 1 (greater than)

Examples

module('Example module')

test('Example unit test', function(assert) {
  assert.eq(2, 2);
  assert.neq(-2, 2);
  assert.lt(-2, 2);
  assert.lte(2, 2);
  assert.gt(2, -2);
  assert.gte(2, 2);

  assert.compare(-2, 2, -1);
});

For more examples, refer to the unit tests.
