QUnit.dump.parse()

QUnit.dump.parse( data )

Extensible data dumping and string serialization.

This method does string serialization by parsing data structures and objects. It parses DOM elements to a string representation of their outer HTML. By default, nested structures will be displayed up to five levels deep. Anything beyond that is replaced by [object Object] and [object Array] placeholders.

If you need more or less output, change the value of QUnit.config.maxDepth, representing how deep the elements should be parsed.

Changelog

| QUnit 2.1 | The QUnit.jsDump alias was removed. | QUnit 1.15 | The QUnit.jsDump interface was renamed to QUnit.dump. The QUnit.jsDump alias is deprecated.

Examples

The following is an example from grunt-contrib-qunit, which sends results from QUnit (running in Headless Chrome) to a CLI tool.

QUnit.log(function (obj) {
  var actual;
  var expected;

  if (!obj.result) {
    // Format before sending
    actual = QUnit.dump.parse(obj.actual);
    expected = QUnit.dump.parse(obj.expected);
  }

  // ...
});

This example shows the formatted representation of a DOM element.

var qHeader = document.getElementById('qunit-header');
var parsed = QUnit.dump.parse(qHeader);

console.log(parsed);

// Logs: '<h1 id="qunit-header"></h1>'

Limit output to one or two levels

var input = {
  parts: {
    front: [],
    back: []
  }
};
QUnit.config.maxDepth = 1;
console.log(QUnit.dump.parse(input));
// Logs: { "parts": [object Object] }

QUnit.config.maxDepth = 2;
console.log(QUnit.dump.parse(input));
// Logs: { "parts": { "back": [object Array], "front": [object Array] } }
