assert.notPropEqual()

version added: 1.11

notPropEqual( actual, expected [, message ] )

A strict comparison of an object’s own properties, checking for inequality.

The notPropEqual assertion uses the strict inverted comparison operator (!==) to compare the actual and expected arguments as Objects regarding only their properties but not their constructors.

When they aren’t equal, the assertion passes; otherwise, it fails. When it fails, both actual and expected values are displayed in the test result, in addition to a given message.

equal() can be used to test equality.

propEqual() can be used to test strict equality of an Object properties.

Examples

Compare the values of two objects properties.

QUnit.test( "notPropEqual test", function( assert ) {
  function Foo( x, y, z ) {
    this.x = x;
    this.y = y;
    this.z = z;
  }
  Foo.prototype.doA = function () {};
  Foo.prototype.doB = function () {};
  Foo.prototype.bar = 'prototype';

  var foo = new Foo( 1, "2", [] );
  var bar = new Foo( "1", 2, {} );
  assert.notPropEqual( foo, bar, "Properties values are strictly compared." );
});
