+ * 2) Set expectations
+ * expect(addMonitor).andReturn((threshold, monitorPtr, callback) => {

+ *
+ * The mocking API is blink agnostic and is designed such that other engines
+ * could implement it too. Here are the symbols that are exposed to tests:
+ *
+ * - function addMonitor(): the main/only function that can be mocked.
+ * - function expect(): the main/only function that enables us to mock it.
+ * - function close(): disconnects the interceptor.
+ * - enum UserIdleState {IDLE, ACTIVE}: blink agnostic constants.
+ * - enum ScreenIdleState {LOCKED, UNLOCKED}: blink agnostic constants.

+/**
+ * Notes for people who want to edit this file (not just use it as a library):
+ *
+ * Most of the interesting stuff happens in the derived classes of IdlObject,
+ * especially IdlInterface. The entry point for all IdlObjects is .test(),
+ * which is called by IdlArray.test(). An IdlObject is conceptually just
+ * "thing we want to run tests on", and an IdlArray is an array of IdlObjects
+ * with some additional data thrown in.
+ *
+ * The object model is based on what WebIDLParser.js produces, which is in turn
+ * based on its pegjs grammar. If you want to figure out what properties an
+ * object will have from WebIDLParser.js, the best way is to look at the
+ * grammar:
+ *
+ * https://github.com/darobin/webidl.js/blob/master/lib/grammar.peg
+ *
+ * So for instance:
+ *
+ * // interface definition
+ * interface
+ * = extAttrs:extendedAttributeList? S? "interface" S name:identifier w herit:ifInheritance? w "{" w mem:ifMember* w "}" w ";" w
+ * { return { type: "interface", name: name, inheritance: herit, members: mem, extAttrs: extAttrs }; }
+ *
+ * This means that an "interface" object will have a .type property equal to
+ * the string "interface", a .name property equal to the identifier that the
+ * parser found, an .inheritance property equal to either null or the result of
+ * the "ifInheritance" production found elsewhere in the grammar, and so on.
+ * After each grammatical production is a JavaScript function in curly braces
+ * that gets called with suitable arguments and returns some JavaScript value.
+ *
+ * (Note that the version of WebIDLParser.js we use might sometimes be
+ * out-of-date or forked.)
+ *
+ * The members and methods of the classes defined by this file are all at least
+ * briefly documented, hopefully.

+# `testharness.js` test suite
+
+The test suite for the `testharness.js` testing framework.
+
+## Executing Tests
+
+Install the following dependencies:
+
+- [Python 2.7.9+](https://www.python.org/)
+- [the tox Python package](https://tox.readthedocs.io/en/latest/)
+- [the Mozilla Firefox web browser](https://mozilla.org/firefox)
+- [the GeckoDriver server](https://github.com/mozilla/geckodriver)
+
+Make sure `geckodriver` can be found in your `PATH`.
+
+Currently, the tests should be run with the latest *Firefox Nightly*. In order to
+specify the path to Firefox Nightly, use the following command-line option:
+
+ tox -- --binary=/path/to/FirefoxNightly
+
+### Automated Script
+
+Alternatively, you may run `tools/ci/ci_resources_unittest.sh`, which only depends on
+Python 2. The script will install other dependencies automatically and start `tox` with
+the correct arguments.
+
+## Authoring Tests
+
+Test cases are expressed as `.html` files located within the `tests/unit/` and
+`tests/functional/` sub-directories. Each test should include the
+`testharness.js` library with the following markup:
+
+ <script src="/resources/testharness.js"></script>
+ <script src="/resources/testharnessreport.js"></script>
+
+This should be followed by one or more `<script>` tags that interface with the
+`testharness.js` API in some way. For example:
+
+ <script>
+ test(function() {
+ 1 = 1;
+ }, 'This test is expected to fail.');
+ </script>
+
+### Unit tests
+
+The "unit test" type allows for concisely testing the expected behavior of
+assertion methods. These tests may define any number of sub-tests; the
+acceptance criteria is simply that all tests executed pass.
+
+### Functional tests
+
+Thoroughly testing the behavior of the harness itself requires ensuring a
+number of considerations which cannot be verified with the "unit testing"
+strategy. These include:
+
+- Ensuring that some tests are not run
+- Ensuring conditions that cause test failures
+- Ensuring conditions that cause harness errors
+
+Functional tests allow for these details to be verified. Every functional test
+must include a summary of the expected results as a JSON string within a
+`<script>` tag with an `id` of `"expected"`, e.g.:
+
+ <script type="text/json" id="expected">
+ {
+ "summarized_status": {
+ "message": null,
+ "stack": null,
+ "status_string": "OK"
+ },
+ "summarized_tests": [
+ {
+ "message": "ReferenceError: invalid assignment left-hand side",
+ "name": "Sample HTML5 API Tests",
+ "properties": {},
+ "stack": "(implementation-defined)",
+ "status_string": "FAIL"
+ }
+ ],
+ "type": "complete"
+ }
+ </script>

+ * Template code
+ *
+ * A template is just a JavaScript structure. An element is represented as:

+ * [tag_name, {attr_name:attr_value}, child1, child2]
+ *
+ * the children can either be strings (which act like text nodes), other templates or
+ * functions (see below)
+ *
+ * A text node is represented as
+ *
+ * ["{text}", value]
+ *
+ * String values have a simple substitution syntax; ${foo} represents a variable foo.
+ *
+ * It is possible to embed logic in templates by using a function in a place where a
+ * node would usually go. The function must either return part of a template or null.
+ *
+ * In cases where a set of nodes are required as output rather than a single node
+ * with children it is possible to just use a list
+ * [node1, node2, node3]
+ *
+ * Usage:
+ *
+ * render(template, substitutions) - take a template and an object mapping
+ * variable names to parameters and return either a DOM node or a list of DOM nodes
+ *
+ * substitute(template, substitutions) - take a template and variable mapping object,
