assert.notPropEqual()

version added: 1.11.0.

Description

notPropEqual( actual, expected, message = "" )

Compare an object’s own properties using a strict inequality comparison.

The notPropEqual assertion compares only an object’s own properties, using the strict inequality operator (!==).

The test passes if there are properties with different values, or extra properties, or missing properties.

• Use assert.notPropContains() to only check for the absence or inequality of some properties.
• Use assert.propEqual() to test for equality of properties instead.

Examples

Compare the values of two objects properties.

QUnit.test('example', assert => {
  class Foo {
    constructor () {
      this.x = '1';
      this.y = 2;
    }

    walk () {}
    run () {}
  }

  const foo = new Foo();

  // succeeds, only own property values are compared (using strict equality),
  // and property "x" is indeed not equal (string instead of number).
  assert.notPropEqual(foo, {
    x: 1,
    y: 2
  });
});
