rf-selenium

Guidance for creating Robot Framework browser tests with SeleniumLibrary and Selenium WebDriver. These tools control browsers such as Chrome and Firefox.

In plain words
What is it for?
Use it to automate web pages, fill forms, handle windows and frames, run JavaScript, and capture screenshots when tests fail.
Why use it?
It helps avoid unreliable browser tests caused by missing waits, driver setup, or difficult browser interactions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

rf-selenium scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SeleniumLibrary Skill

Create browser automation tests using SeleniumLibrary with Selenium WebDriver.

Quick Reference

SeleniumLibrary provides browser automation using Selenium WebDriver. Unlike Browser Library, explicit waits are often required for reliable test execution.

Installation

pip install robotframework-seleniumlibrary

WebDriver binaries (chromedriver, geckodriver, etc.) must be in PATH. Selenium 4.6+ includes Selenium Manager which handles driver downloads automatically, so executable_path and webdriver-manager are often unnecessary with modern Selenium. For older versions:

pip install webdriver-manager

Library Import

*** Settings ***
Library    SeleniumLibrary    timeout=10s    implicit_wait=0s

Import Options

Option Default Description
timeout 5s Default timeout for wait keywords
implicit_wait 0s Implicit wait (0s is recommended; use explicit waits instead)
run_on_failure Capture Page Screenshot Keyword to run on failure
screenshot_root_directory None Directory for screenshots
plugins None Plugin modules to load

WebDriver Setup Options

Chrome

# Basic
Open Browser    ${URL}    chrome

# Headless
Open Browser    ${URL}    headless_chrome

# With Options
Open Browser    ${URL}    chrome    options=add_argument("--headless");add_argument("--no-sandbox")

# With WebDriver Manager
Open Browser    ${URL}    chrome    executable_path=${DRIVER_PATH}

Firefox

Open Browser    ${URL}    firefox
Open Browser    ${URL}    headless_firefox
Open Browser    ${URL}    firefox    options=add_argument("--headless")

Edge

Open Browser    ${URL}    edge
Open Browser    ${URL}    headless_edge

Locator Strategies

SeleniumLibrary requires strategy prefixes except for id and name attributes.

Strategy Syntax Example
id id=value or value id=username or username
name name=value or value name=email
xpath xpath=expression xpath=//button[@type='submit']
css css=selector css=button.primary
class class=name class=submit-btn
tag tag=name tag=button
link link=text link=Click here
partial link partial link=text partial link=Click
dom dom=expression dom=document.forms[0]
jquery jquery=selector jquery=button:visible
data data=attr:value data=testid:submit
default (no prefix) username (tries id, then name)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rf-selenium is a skill published in the GitHub repository manykarim/robotframework-agentskills (30 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 46 tokens to every session and 2,592 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
