testdriver.js Automation¶

Table of Contents

Markup
API

testdriver.js provides a means to automate tests that cannot be written purely using web platform APIs. Outside of automation contexts, it allows human operators to provide expected input manually (for operations which may be described in simple terms).

It is currently supported only for testharness.js tests.

Markup¶

The testdriver.js and testdriver-vendor.js must both be included in any document that uses testdriver (and in the top-level test document when using testdriver from a different context):

<script src="/resources/testdriver.js"></script>
<script src="/resources/testdriver-vendor.js"></script>

API¶

testdriver.js exposes its API through the test_driver variable in the global scope.

User Interaction¶

static test_driver.click(element)¶

Triggers a user-initiated click

If element isn’t inside the viewport, it will be scrolled into view before the click occurs.

If element is from a different browsing context, the command will be run in that context.

Matches the behaviour of the Element Click WebDriver command.

Note: If the element to be clicked does not have a unique ID, the document must not have any DOM mutations made between the function being called and the promise settling.

Arguments

element (Element) – element to be clicked

Returns

Promise – fulfilled after click occurs, or rejected in the cases the WebDriver command errors

static test_driver.send_keys(element, keys)¶

Send keys to an element.

If element isn’t inside the viewport, it will be scrolled into view before the click occurs.

If element is from a different browsing context, the command will be run in that context. The test must not depend on the window.name property being unset on the target window.

To send special keys, send the respective key’s codepoint, as defined by WebDriver. For example, the “tab” key is represented as “\uE004”.

Note: these special-key codepoints are not necessarily what you would expect. For example, <kbd>Esc</kbd> is the invalid Unicode character \uE00C, not the \u001B Escape character from ASCII.

This matches the behaviour of the Send Keys WebDriver command.

Note: If the element to be clicked does not have a unique ID, the document must not have any DOM mutations made between the function being called and the promise settling.

Arguments

element (Element) – element to send keys to
keys (String) – keys to send to the element

Returns

Promise – fulfilled after keys are sent, or rejected in the cases the WebDriver command errors

static test_driver.action_sequence(actions, context)¶

Send a sequence of actions

This function sends a sequence of actions to perform.

Matches the behaviour of the Actions feature in WebDriver.

Authors are encouraged to use the test_driver.Actions() builder rather than invoking this API directly.

Arguments

actions (Array) – an array of actions. The format is the same as the actions property of the Perform Actions WebDriver command. Each element is an object representing an input source and each input source itself has an actions property detailing the behaviour of that source at each timestep (or tick). Authors are not expected to construct the actions sequence by hand, but to use the builder api provided in testdriver-actions.js
context (WindowProxy) – Browsing context in which to run the call, or null for the current browsing context.

Returns

Promise – fulfilled after the actions are performed, or rejected in the cases the WebDriver command errors

static test_driver.bless(intent, action, context)¶

Trigger user interaction in order to grant additional privileges to a provided function.

See Tracking user activation.

Arguments

intent (String) – a description of the action which must be triggered by user interaction
action (function) – code requiring escalated privileges
context (WindowProxy) – Browsing context in which to run the call, or null for the current browsing context.

Returns

Promise – fulfilled following user interaction and execution of the provided action function; rejected if interaction fails or the provided function throws an error

var mediaElement = document.createElement('video');

test_driver.bless('initiate media playback', function () {
  mediaElement.play();
});

Window State¶

static test_driver.minimize_window(context)¶

const timeoutPromise = new Promise(resolve => {
    t.step_timeout(() => resolve('TIMEOUT', 3000))
});

const reading = { x: 1, y: 2, z: 3 };
await test_driver.update_virtual_sensor('gyroscope', 'reading');

context (WindowProxy) – Browsing context in which to run the call, or null for the current browsing context.

Returns

Promise – Fulfilled with an Object with the properties described in Get Virtual Sensor Information. Rejected in case the WebDriver command errors out (including if a virtual sensor of the given type does not exist).

Using test_driver in other browsing contexts¶

Testdriver can be used in browsing contexts (i.e. windows or frames) from which it’s possible to get a reference to the top-level test context. There are two basic approaches depending on whether the context in which testdriver is used is same-origin with the test context, or different origin.

For same-origin contexts, the context can be passed directly into the testdriver API calls. For functions that take an element argument this is done implicitly using the owner document of the element. For functions that don’t take an element, this is done via an explicit context argument, which takes a WindowProxy object.

Example:

let win = window.open("example.html")
win.onload = () => {
  await test_driver.set_permission({ name: "background-fetch" }, "denied", win);
}

static test_driver.set_test_context(context)¶

Set the context in which testharness.js is loaded

Arguments

context (WindowProxy) – the window containing testharness.js

static test_driver.message_test(msg)¶

postMessage to the context containing testharness.js

Arguments

msg (Object) – the data to POST

For cross-origin cases, passing in the context doesn’t work because of limitations in the WebDriver protocol used to implement testdriver in a cross-browser fashion. Instead one may include the testdriver scripts directly in the relevant document, and use the test_driver.set_test_context API to specify the browsing context containing testharness.js. Commands are then sent via postMessage to the test context. For convenience there is also a test_driver.message_test function that can be used to send arbitrary messages to the test window. For example, in an auxillary browsing context:

test_driver.set_test_context(window.opener)
await test_driver.click(document.getElementsByTagName("button")[0])
test_driver.message_test("click complete")

The requirement to have a handle to the test window does mean it’s currently not possible to write tests where such handles can’t be obtained e.g. in the case of rel=noopener.

Actions¶

Markup¶

To use the Actions API testdriver-actions.js must be included in the document, in addition to testdriver.js:

<script src="/resources/testdriver-actions.js"></script>

API¶

class Actions(defaultTickDuration=16)¶

Builder for creating a sequence of actions

The actions are dispatched once test_driver.Actions.send() is called. This returns a promise which resolves once the actions are complete.

The other methods on test_driver.Actions() object are used to build the sequence of actions that will be sent. These return the Actions object itself, so the actions sequence can be constructed by chaining method calls.

Internally test_driver.Actions.send() invokes test_driver.action_sequence().

Arguments

    .setContext(frames[0])
    .keyDown("p")
    .keyUp("p");
await actions.send();

Note that if an action uses an element reference, the context will be derived from that element, and must match any explicitly set context. Using elements in multiple contexts in a single action chain is not supported.
