Project description
robotframework-browser
Robot Framework Browser library powered by Playwright. Propelling browser automation into the future!
Aiming for :rocket: speed, :white_check_mark: reliability and :microscope: visibility.
See keyword documentation and web page for more details.
Installation instructions
For both installation options only Python 3.10 or newer is supported. There are two main ways to install Browser library, with or without user having NodeJS installed.
The easiest way to install the Browser library is to use the robotframework-browser-batteries package (BrowserBatteries). BrowserBatteries contains precompiled NodeJS binaries and NodeJS dependencies, so that users do not need to install NodeJS or its Node-side dependencies by them self.
Limitations:
- BrowserBatteries may not be available for every operating system or processor architecture.
- If you develop plugins that require third-party NodeJS modules, those modules are not compiled into the BrowserBatteries package.
See Installation without NodeJS for more details.
If BrowserBatteries package is not suitable for you, for some reason, then you need to install NodeJS, install robotframework-browser and install NodeJS dependencies. See more detail in Installation with NodeJS chapter
Installation without NodeJS
- Update pip
pip install -U pipto ensure latest version is used - Install robotframework-browser and robotframework-browser-batteries from the commandline:
pip install robotframework-browser[bb] - Install the Playwright browser binaries, run:
rfbrowser install
- if
rfbrowseris not found, trypython -m Browser.entry install
Installation with NodeJS
From Node side 20, 22 and 24 LTS versions are supported.
- Install NodeJS e.g. from https://nodejs.org/en/download/
- Update pip
pip install -U pipto ensure latest version is used - Install robotframework-browser from the commandline:
pip install robotframework-browser - Install the node dependencies: run
rfbrowser initin your shell
- if
rfbrowseris not found, trypython -m Browser.entry init
Please note that by default Chromium, Firefox and WebKit browser are installed, even those would be already
installed in the system. The installation size depends on the operating system, but usually is +700Mb.
It is possible to skip browser binaries installation with rfbrowser install-browser --skip-browsers
or rfbrowser init --skip-browsers command, but then user is responsible for Playwright browser binary
installation. It is possible to install only selected browser binaries by adding
chromium, firefox or webkit as arguments to init command. Example rfbrowser init firefox would install
only Firefox binaries and rfbrowser install-browser firefox chromium would install both Firefox and
Chromium binaries.
Or use the docker images . Documented at docker/README.md.
Install with transformer
Starting from release 18.3.0 Browser library has optional dependency with
Robotidy. Install library with Robotidy, run install with:
pip install robotframework-browser[tidy]. Starting from 18.3.0 release, library will provide external
Robotidy transformer. Transformer provided
by Browser library can be run with command: rfbrowser transform --transformer-name /path/to/tests. Example:
rfbrowser transform --wait-until-network-is-idle /path/to/tests would transform deprecated Wait Until Network Is Idle
keyword to Wait For Load State keyword. To see full list of transformers provided by Browser library, run
command: rfbrowser transform --help.
Update instructions without NodeJS
To upgrade your already installed robotframework-browser and robotframework-browser-batteries follow steps in below. Please note that robotframework-browser and robotframework-browser-batteries packages are tied together and having different versions of these packages is not supported.
- Update from commandline:
pip install -U robotframework-browser robotframework-browser-batteries - Clean old node side dependencies and browser binaries:
rfbrowser clean-node - Install the node dependencies for the newly installed version:
rfbrowser install
Update instructions with NodeJS
To upgrade your already installed robotframework-browser library
- Update from commandline:
pip install -U robotframework-browser - Clean old node side dependencies and browser binaries:
rfbrowser clean-node - Install the node dependencies for the newly installed version:
rfbrowser init
Uninstall instructions
To completely uninstall library, including the browser binaries installed by Playwright, run following commands:
- Clean old node side dependencies and browser binaries:
rfbrowser clean-node - Uninstall with pip:
pip uninstall robotframework-browser - If you have BrowserBatteries installed, also run:
pip uninstall robotframework-browser-batteries
Examples
Testing with Robot Framework
*** Settings ***
Library Browser
*** Test Cases ***
Example Test
New Page https://playwright.dev
Get Text h1 contains Playwright
and testing with Python.
import Browser
browser = Browser.Browser()
browser.new_page("https://playwright.dev")
assert 'Playwright' in browser.get_text("h1")
browser.close_browser()
and extending with JavaScript
async function myGoToKeyword(url, page, logger) {
logger("Going to " + url)
return await page.goto(url);
}
myGoToKeyword.rfdoc = "This is my own go to keyword";
exports.__esModule = true;
exports.myGoToKeyword = myGoToKeyword;
*** Settings ***
Library Browser jsextension=${CURDIR}/mymodule.js
*** Test Cases ***
Example Test
New Page
myGoToKeyword https://www.robotframework.org
See example. Ready made extensions and a place to share your own at robotframework-browser-extensions.
Ergonomic selector syntax, supports chaining of text, css and xpath selectors
# Select element containing text "Login" with text selector strategy
# and select it's parent `input` element with xpath
Click "Login" >> xpath=../input
# Select element with CSS strategy and select button in it with text strategy
Click div.dialog >> "Ok"
Evaluate in browser page
New Page ${LOGIN_URL}
${ref}= Get Element h1
Get Property ${ref} innerText == Login Page
Evaluate JavaScript ${ref} (elem) => elem.innerText = "abc"
Get Property ${ref} innerText == abc
Asynchronously waiting for HTTP requests and responses
# The button with id `delayed_request` fires a delayed request. We use a promise to capture it.
${promise}= Promise To Wait For Response matcher= timeout=3s
Click \#delayed_request
${body}= Wait For ${promise}
Device Descriptors
${device}= Get Device iPhone X
New Context &{device}
New Page
Get Viewport Size # returns { "width": 375, "height": 812 }
Sending HTTP requests and parsing their responses
${response}= HTTP /api/post POST {"name": "John"}
Should Be Equal ${response.status} ${200}
Parallel test execution using Pabot
You can let RF Browser spawn separate processes for every pabot process. This is very simple, just run the tests normally using pabot (see https://github.com/mkorpela/pabot#basic-use ). However if you have small tests do not use --testlevelsplit, it will cause lots of overhead because tests cannot share the browsers in any case.
You can share the node side RF Browser processes by using the ROBOT_FRAMEWORK_BROWSER_NODE_PORT environment variable, and from Browser.utils import spawn_node_process helper (see the docs for the helper ). This saves some overhead based on how many splits of tests you are running. Clean up the process afterwards.
Re-using authentication credentials
- Figure out how the page is storing authentication
- If it is localstorage or cookies
Save Storage Stateshould work. See usage example: https://marketsquare.github.io/robotframework-browser/Browser.html#Save%20Storage%20State
Development
See CONTRIBUTING.md for development instructions.
