import LiteYouTube from '@site/src/components/LiteYouTube';

Version 1.58​

UI Mode and Trace Viewer Improvements​

  • New 'system' theme option follows your OS dark/light mode preference
  • Search functionality (Cmd/Ctrl+F) is now available in code editors
  • Network details panel has been reorganized for better usability
  • JSON responses are now automatically formatted for readability

Thanks to @cpAdm for contributing these improvements!

Miscellaneous​

BrowserType.connectOverCDP() now accepts an is_local option. When set to True, it tells copilotbrowser that it runs on the same host as the CDP server, enabling file system optimizations.

Breaking Changes ⚠️​

  • Removed _react and _vue selectors. See locators guide for alternatives.

  • Removed :light selector engine suffix. Use standard CSS selectors instead.

  • Option devtools from BrowserType.launch() has been removed. Use args=['--auto-open-devtools-for-tabs'] instead.

  • Removed macOS 13 support for WebKit. We recommend to upgrade your macOS version, or keep using an older copilotbrowser version.

Browser Versions​

  • Chromium 145.0.7632.6
  • Mozilla Firefox 146.0.1
  • WebKit 26.0

This version was also tested against the following stable channels:

Version 1.57​

Chrome for Testing​

Starting with this release, copilotbrowser switches from Chromium, to using Chrome for Testing builds. Both headed and headless browsers are subject to this. Your tests should still be passing after upgrading to copilotbrowser 1.57.

We're expecting no functional changes to come from this switch. The biggest change is the new icon and title in your toolbar.

new and old logo

If you still see an unexpected behaviour change, please file an issue.

On Arm64 Linux, copilotbrowser continues to use Chromium.

Breaking Change​

After 3 years of being deprecated, we removed page.accessibility from our API. Please use other libraries such as Axe if you need to test page accessibility. See our Node.js guide for integration with Axe.

New APIs​

  • Worker.event('console') event is emitted when JavaScript within the worker calls one of console API methods, e.g. console.log or console.dir. Worker.waitForEvent() can be used to wait for it.
  • Locator.description() returns locator description previously set with Locator.describe().
  • New option Locator.click.steps in Locator.click() and Locator.dragTo() that configures the number of mousemove events emitted while moving the mouse pointer to the target element.
  • Network requests issued by Service Workers are now reported and can be routed through the BrowserContext, only in Chromium. You can opt out using the copilotbrowser_DISABLE_SERVICE_WORKER_NETWORK environment variable.
  • Console messages from Service Workers are dispatched through Worker.event('console'). You can opt out of this using the copilotbrowser_DISABLE_SERVICE_WORKER_CONSOLE environment variable.

    # Save storage state into the file. Make sure to include IndexedDB.
    storage = await context.storage_state(path="state.json", indexed_db=True)

    # Create a new context with the saved storage state.
    context = await browser.new_context(storage_state="state.json")
  • New option Locator.filter.visible for Locator.filter() allows matching only visible elements.

    # Ignore invisible todo items.
    todo_items = page.get_by_test_id("todo-item").filter(visible=True)
    # Check there are exactly 3 visible ones.
    await expect(todo_items).to_have_count(3)
  • New option contrast for methods Page.emulateMedia() and Browser.newContext() allows to emulate the prefers-contrast media feature.

Version 1.49​

Aria snapshots​

New assertion LocatorAssertions.toMatchAriaSnapshot() verifies page structure by comparing to an expected accessibility tree, represented as YAML.

page.goto("https://copilotbrowser.dev")
expect(page.locator('body')).to_match_aria_snapshot('''
- banner:
- heading /copilotbrowser enables reliable/ [level=1]
- link "Get started"
- link "Star microsoft/copilotbrowser on GitHub"
- main:
- img "Browsers (Chromium, Firefox, WebKit)"
- heading "Any browser • Any platform • One API"
''')

You can generate this assertion with Test Generator or by calling Locator.ariaSnapshot().

Learn more in the aria snapshots guide.

Tracing groups​

New method Tracing.group() allows you to visually group actions in the trace viewer.

# All actions between group and group_end
# will be shown in the trace viewer as a group.
page.context.tracing.group("Open copilotbrowser.dev > API")
page.goto("https://dayour.github.io/copilotbrowser/")
page.get_by_role("link", name="API").click()
page.context.tracing.group_end()

Breaking: chrome and msedge channels switch to new headless mode​

This change affects you if you're using one of the following channels in your copilotbrowser.config.ts:

  • chrome, chrome-dev, chrome-beta, or chrome-canary
  • msedge, msedge-dev, msedge-beta, or msedge-canary

After updating to copilotbrowser v1.49, run your test suite. If it still passes, you're good to go. If not, you will probably need to update your snapshots, and adapt some of your test code around PDF viewers and extensions. See issue #33566 for more details.

Try new Chromium headless​

You can opt into the new headless mode by using 'chromium' channel. As official Chrome documentation puts it:

New Headless on the other hand is the real Chrome browser, and is thus more authentic, reliable, and offers more features. This makes it more suitable for high-accuracy end-to-end web app testing or browser extension testing.

See issue #33566 for the list of possible breakages you could encounter and more details on Chromium headless. Please file an issue if you see any problems after opting in.

pytest test_login.py --browser-channel chromium

Miscellaneous​

Version 1.48​

WebSocket routing​

New methods Page.routeWebSocket() and BrowserContext.routeWebSocket() allow to intercept, modify and mock WebSocket connections initiated in the page. Below is a simple example that mocks WebSocket communication by responding to a "request" with a "response".

def message_handler(ws: WebSocketRoute, message: Union[str, bytes]):
if message == "request":
ws.send("response")

page.route_web_socket("/ws", lambda ws: ws.on_message(
lambda message: message_handler(ws, message)
))

See WebSocketRoute for more details.

Version 1.45​

Clock​

Utilizing the new Clock API allows to manipulate and control time within tests to verify time-related behavior. This API covers many common scenarios, including:

  • testing with predefined time;
  • keeping consistent time and timers;
  • monitoring inactivity;
  • ticking through time manually.
# Initialize clock with some time before the test time and let the page load
# naturally. `Date.now` will progress as the timers fire.
page.clock.install(time=datetime.datetime(2024, 2, 2, 8, 0, 0))
page.goto("http://localhost:3333")

# Pretend that the user closed the laptop lid and opened it again at 10am.
# Pause the time once reached that point.
page.clock.pause_at(datetime.datetime(2024, 2, 2, 10, 0, 0))

# Assert the page state.
expect(page.get_by_test_id("current-time")).to_have_text("2/2/2024, 10:00:00 AM")

# Close the laptop lid again and open it at 10:30am.
page.clock.fast_forward("30:00")
expect(page.get_by_test_id("current-time")).to_have_text("2/2/2024, 10:30:00 AM")

See the clock guide for more details.

Miscellaneous​

    page.get_by_label("Upload directory").set_input_files('mydir')
  • Multiple methods like Locator.click() or Locator.press() now support a ControlOrMeta modifier key. This key maps to Meta on macOS and maps to Control on Windows and Linux.

    # Press the common keyboard shortcut Control+S or Meta+S to trigger a "Save" operation.
    page.keyboard.press("ControlOrMeta+S")
  • New property httpCredentials.send in APIRequest.newContext() that allows to either always send the Authorization header or only send it in response to 401 Unauthorized.

    locator = page.get_by_test_id("save-button")
    expect(locator).to_have_role("button")

Locator handler

  • After executing the handler added with Page.addLocatorHandler(), copilotbrowser will now wait until the overlay that triggered the handler is not visible anymore. You can opt-out of this behavior with the new no_wait_after option.
  • You can use new times option in Page.addLocatorHandler() to specify maximum number of times the handler should be run.
  • The handler in Page.addLocatorHandler() now accepts the locator as argument.
  • New Page.removeLocatorHandler() method for removing previously added locator handlers.
locator = page.get_by_text("This interstitial covers the button")
page.add_locator_handler(locator, lambda overlay: overlay.locator("#close").click(), times=3, no_wait_after=True)
# Run your tests that can be interrupted by the overlay.

    locator = page.locator("iframe[name='embedded']")
    # ...
    frame_locator = locator.content_frame
    frame_locator.getByRole("button").click()
  • New method FrameLocator.owner() converts a FrameLocator object to a Locator. This can be useful when you have a FrameLocator object obtained somewhere, and later on would like to interact with the iframe element.

# Setup the handler.
page.add_locator_handler(
page.get_by_role("heading", name="Hej! You are in control of your cookies."),
lambda: page.get_by_role("button", name="Accept all").click(),
)
# Write the test as usual.

Consider a scenario where you'd like to click on a "New email" button, but sometimes a security settings dialog shows up instead. In this case, you can wait for either a "New email" button, or a dialog and act accordingly:

    new_email = page.get_by_role("button", name="New email")
    dialog = page.get_by_text("Confirm security settings")
    expect(new_email.or_(dialog)).is_visible()
    if (dialog.is_visible()):
    page.get_by_role("button", name="Dismiss").click()
    new_email.click()
  • Use new options Locator.filter.hasNot and Locator.filter.hasNotText in Locator.filter() to find elements that do not match certain conditions.

    row_locator = page.locator("tr")
    row_locator.filter(has_not_text="text in column 1").filter(
    has_not=page.get_by_role("button", name="column 2 button")
    ).screenshot()
  • Use new web-first assertion LocatorAssertions.toBeAttached() to ensure that the element is present in the page's DOM. Do not confuse with the LocatorAssertions.toBeVisible() that ensures that element is both attached & visible.

New APIs​

  • Locator.or()
  • New option Locator.filter.hasNot in Locator.filter()
  • New option Locator.filter.hasNotText in Locator.filter()
  • LocatorAssertions.toBeAttached()
  • New option Route.fetch.timeout in Route.fetch()

⚠️ Breaking change​

This version was also tested against the following stable channels:

  • Google Chrome 107
  • Microsoft Edge 107

Version 1.27​

Locators​

With these new APIs writing locators is a joy:

  • Page.getByText() to locate by text content.
  • Page.getByRole() to locate by ARIA role, ARIA attributes and accessible name.
  • Page.getByLabel() to locate a form control by associated label's text.
  • Page.getByTestId() to locate an element based on its data-testid attribute (other attribute can be configured).
  • Page.getByPlaceholder() to locate an input by placeholder.
  • Page.getByAltText() to locate an element, usually image, by its text alternative.
  • Page.getByTitle() to locate an element by its title.
page.get_by_label("User Name").fill("John")

page.get_by_label("Password").fill("secret-password")

page.get_by_role("button", name="Sign in").click()

expect(page.get_by_text("Welcome, John!")).to_be_visible()

All the same methods are also available on Locator, FrameLocator and Frame classes.

Other highlights​

  • As announced in v1.25, Ubuntu 18 will not be supported as of Dec 2022. In addition to that, there will be no WebKit updates on Ubuntu 18 starting from the next copilotbrowser release.

Behavior Changes​

  • LocatorAssertions.toHaveAttribute() with an empty value does not match missing attribute anymore. For example, the following snippet will succeed when button does not have a disabled attribute.

    expect(page.get_by_role("button")).to_have_attribute("disabled", "")

Browser Versions​

  • Chromium 107.0.5304.18
  • Mozilla Firefox 105.0.1
  • WebKit 16.0

This version was also tested against the following stable channels:

  • Google Chrome 106
  • Microsoft Edge 106

Version 1.26​

Assertions​

  • New option enabled for LocatorAssertions.toBeEnabled().
  • LocatorAssertions.toHaveText() now pierces open shadow roots.
  • New option editable for LocatorAssertions.toBeEditable().
  • New option visible for LocatorAssertions.toBeVisible().

Other highlights​

  • New option max_redirects for APIRequestContext.get() and others to limit redirect count.
  • Python 3.11 is now supported.

Behavior Change​

A bunch of copilotbrowser APIs already support the wait_until: "domcontentloaded" option. For example:

page.goto("https://copilotbrowser.dev", wait_until="domcontentloaded")

Prior to 1.26, this would wait for all iframes to fire the DOMContentLoaded event.

To align with web specification, the 'domcontentloaded' value only waits for the target frame to fire the 'DOMContentLoaded' event. Use wait_until="load" to wait for all iframes.

Browser Versions​

| | Ubuntu 20.04 | Ubuntu 22.04 | Debian 11 | :--- | :---: | :---: | :---: | :---: | | Chromium | ✅ | ✅ | ✅ | | WebKit | ✅ | ✅ | ✅ | | Firefox | ✅ | ✅ | ✅ |

New introduction docs​

We rewrote our Getting Started docs to be more end-to-end testing focused. Check them out on copilotbrowser Github.io.

Version 1.23​

Network Replay​

Now you can record network traffic into a HAR file and re-use this traffic in your tests.

To record network into HAR file:

npx copilotbrowser open --save-har=github.har.zip https://github.com/microsoft

Alternatively, you can record HAR programmatically:

context = await browser.new_context(record_har_path="github.har.zip")
# ... do stuff ...
await context.close()
context = browser.new_context(record_har_path="github.har.zip")
# ... do stuff ...
context.close()

Use the new methods Page.routeFromHAR() or BrowserContext.routeFromHAR() to serve matching responses from the HAR file:

await context.route_from_har("github.har.zip")
context.route_from_har("github.har.zip")

Read more in our documentation.

Advanced Routing​

You can now use Route.fallback() to defer routing to other handlers.

Consider the following example:

# Remove a header from all requests
async def remove_header_handler(route: Route) -> None:
headers = await route.request.all_headers()
if "if-none-match" in headers:
del headers["if-none-match"]
await route.fallback(headers=headers)

await page.route("**/*", remove_header_handler)

# Abort all images
async def abort_images_handler(route: Route) -> None:
if route.request.resource_type == "image":
await route.abort()
else:
await route.fallback()

await page.route("**/*", abort_images_handler)
# Remove a header from all requests
def remove_header_handler(route: Route) -> None:
headers = route.request.all_headers()
if "if-none-match" in headers:
del headers["if-none-match"]
route.fallback(headers=headers)

page.route("**/*", remove_header_handler)

# Abort all images
def abort_images_handler(route: Route) -> None:
if route.request.resource_type == "image":
route.abort()
else:
route.fallback()

page.route("**/*", abort_images_handler)

Note that the new methods Page.routeFromHAR() and BrowserContext.routeFromHAR() also participate in routing and could be deferred to.

Web-First Assertions Update​

  • New method LocatorAssertions.toHaveValues() that asserts all selected values of <select multiple> element.
  • Methods LocatorAssertions.toContainText() and LocatorAssertions.toHaveText() now accept ignore_case option.

Miscellaneous​

  • If there's a service worker that's in your way, you can now easily disable it with a new context option service_workers:

    context = await browser.new_context(service_workers="block")
    page = await context.new_page()
    context = browser.new_context(service_workers="block")
    page = context.new_page()
  • Using .zip path for recordHar context option automatically zips the resulting HAR:

    context = await browser.new_context(record_har_path="github.har.zip")
    context = browser.new_context(record_har_path="github.har.zip")
  • If you intend to edit HAR by hand, consider using the "minimal" HAR recording mode that only records information that is essential for replaying:

    context = await browser.new_context(record_har_mode="minimal", record_har_path="har.har")
    context = browser.new_context(record_har_mode="minimal", record_har_path="har.har")
  • copilotbrowser now runs on Ubuntu 22 amd64 and Ubuntu 22 arm64.

Version 1.22​

Highlights​

  • New Locator.filter() API to filter an existing locator

    buttons = page.locator("role=button")
    # ...
    submit_button = buttons.filter(has_text="Submit")
    submit_button.click()
  • Codegen now supports generating Pytest Tests

    Graphics

Version 1.21​

Version 1.18​

API Testing​

copilotbrowser for Python 1.18 introduces new API Testing that lets you send requests to the server directly from Python! Now you can:

  • test your server API
  • prepare server side state before visiting the web application in a test
  • validate server side post-conditions after running some actions in the browser

To do a request on behalf of copilotbrowser's Page, use new Page.request API:

# Do a GET request on behalf of page
res = await page.request.get("http://example.com/foo.json")
# Do a GET request on behalf of page
res = page.request.get("http://example.com/foo.json")

Read more in our documentation.

Web-First Assertions​

copilotbrowser for Python 1.18 introduces Web-First Assertions.

Consider the following example:

from copilotbrowser.async_api import Page, expect

async def test_status_becomes_submitted(page: Page) -> None:
# ..
await page.locator("#submit-button").click()
await expect(page.locator(".status")).to_have_text("Submitted")
from copilotbrowser.sync_api import Page, expect

def test_status_becomes_submitted(page: Page) -> None:
# ..
page.locator("#submit-button").click()
expect(page.locator(".status")).to_have_text("Submitted")

copilotbrowser will be re-testing the node with the selector .status until fetched Node has the "Submitted" text. It will be re-fetching the node and checking it over and over, until the condition is met or until the timeout is reached. You can pass this timeout as an option.

Read more in our documentation.

Locator Improvements​

  • Locator.dragTo()

  • Each locator can now be optionally filtered by the text it contains:

    await page.locator("li", has_text="my item").locator("button").click()
    page.locator("li", has_text="my item").locator("button").click()

    Read more in locator documentation

New APIs & changes​

  • Google Chrome 97
  • Microsoft Edge 97

Version 1.17​

Frame Locators​

copilotbrowser 1.17 introduces frame locators - a locator to the iframe on the page. Frame locators capture the logic sufficient to retrieve the iframe and then locate elements in that iframe. Frame locators are strict by default, will wait for iframe to appear and can be used in Web-First assertions.

Graphics

Frame locators can be created with either Page.frameLocator() or Locator.frameLocator() method.

locator = page.frame_locator("my-frame").locator("text=Submit")
locator.click()

Read more at our documentation.

Trace Viewer Update​

copilotbrowser Trace Viewer is now available online at https://trace.copilotbrowser.dev! Just drag-and-drop your trace.zip file to inspect its contents.

NOTE: trace files are not uploaded anywhere; trace.copilotbrowser.dev is a progressive web application that processes traces locally.

  • copilotbrowser Test traces now include sources by default (these could be turned off with tracing option)
  • Trace Viewer now shows test name
  • New trace metadata tab with browser details
  • Snapshots now have URL bar

image

Comes especially handy when working with lists:

order_sent = page.locator("#order-sent")
order_sent.wait_for()

Read more about Locator.waitFor().

Docker support for Arm64​

copilotbrowser Docker image is now published for Arm64 so it can be used on Apple Silicon.

Read more about Docker integration.

🎭 copilotbrowser Trace Viewer​

  • run trace viewer with npx copilotbrowser show-trace and drop trace files to the trace viewer PWA
  • better visual attribution of action targets

Read more about Trace Viewer.

Browser Versions​

  • Chromium 97.0.4666.0
  • Mozilla Firefox 93.0
  • WebKit 15.4

This version of copilotbrowser was also tested against the following stable channels:

  • Google Chrome 94
  • Microsoft Edge 94

Version 1.15​

🖱️ Mouse Wheel​

By using Mouse.wheel() you are now able to scroll vertically or horizontally.

📜 New Headers API​

Previously it was not possible to get multiple header values of a response. This is now possible and additional helper functions are available:

  • Request.allHeaders()
  • Request.headersArray()
  • Request.headerValue()
  • Response.allHeaders()
  • Response.headersArray()
  • Response.headerValue()
  • Response.headerValues()

🌈 Forced-Colors emulation​

Its now possible to emulate the forced-colors CSS media feature by passing it in the Browser.newContext() or calling Page.emulateMedia().

New APIs​

  • Page.route() accepts new times option to specify how many times this route should be matched.
  • Page.setChecked() and Locator.setChecked() were introduced to set the checked state of a checkbox.
  • Request.sizes() Returns resource size information for given http request.
  • Tracing.startChunk() - Start a new trace chunk.
  • Tracing.stopChunk() - Stops a new trace chunk.

Browser Versions​

  • Chromium 96.0.4641.0
  • Mozilla Firefox 92.0
  • WebKit 15.0

Version 1.14​

⚡️ New "strict" mode​

Selector ambiguity is a common problem in automation testing. "strict" mode ensures that your selector points to a single element and throws otherwise.

Pass strict=true into your action calls to opt in.

# This will throw if you have more than one button!
page.click("button", strict=True)

📍 New Locators API​

Locator represents a view to the element(s) on the page. It captures the logic sufficient to retrieve the element at any given moment.

The difference between the Locator and ElementHandle is that the latter points to a particular element, while Locator captures the logic of how to retrieve that element.

Also, locators are "strict" by default!

locator = page.locator("button")
locator.click()

Learn more in the documentation.

🧩 Experimental React and Vue selector engines​

React and Vue selectors allow selecting elements by its component name and/or property values. The syntax is very similar to attribute selectors and supports all attribute selector operators.

page.locator("_react=SubmitButton[enabled=true]").click()
page.locator("_vue=submit-button[enabled=true]").click()

Learn more in the react selectors documentation and the vue selectors documentation.

✨ New nth and visible selector engines​

  • nth selector engine is equivalent to the :nth-match pseudo class, but could be combined with other selector engines.
  • visible selector engine is equivalent to the :visible pseudo class, but could be combined with other selector engines.
# select the first button among all buttons
button.click("button >> nth=0")
# or if you are using locators, you can use first, nth() and last
page.locator("button").first.click()

# click a visible button
button.click("button >> visible=true")

Version 1.12​

🧟‍♂️ Introducing copilotbrowser Trace Viewer​

copilotbrowser Trace Viewer is a new GUI tool that helps exploring recorded copilotbrowser traces after the script ran. copilotbrowser traces let you examine:

  • page DOM before and after each copilotbrowser action
  • page rendering before and after each copilotbrowser action
  • browser network during script execution

Traces are recorded using the new BrowserContext.tracing API:

browser = chromium.launch()
context = browser.new_context()

# Start tracing before creating / navigating a page.
context.tracing.start(screenshots=True, snapshots=True)

page.goto("https://copilotbrowser.dev")

# Stop tracing and export it into a zip archive.
context.tracing.stop(path = "trace.zip")

Traces are examined later with the copilotbrowser CLI:

copilotbrowser show-trace trace.zip

That will open the following GUI:
