npx skills add https://github.com/lambdatest/agent-skills --skill lettuce-skill- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads lettuce-skill automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Lettuce BDD Skill (Legacy)
Note: Lettuce is largely unmaintained. For new Python BDD projects, use Behave instead.
Core Patterns
Feature File (features/login.feature)
Feature: User Login
Scenario: Successful login
Given I navigate to the login page
When I enter "user@test.com" as email
And I enter "password123" as password
And I click login
Then I should see the dashboard
Scenario: Invalid login
Given I navigate to the login page
When I enter "bad@test.com" as email
And I enter "wrong" as password
And I click login
Then I should see "Invalid credentials"
Step Definitions (features/steps.py)
from lettuce import step, world
from selenium import webdriver
from selenium.webdriver.common.by import By
@step(r'I navigate to the login page')
def navigate_to_login(step):
world.browser = webdriver.Chrome()
world.browser.get(world.base_url + '/login')
@step(r'I enter "([^"]*)" as email')
def enter_email(step, email):
el = world.browser.find_element(By.ID, 'email')
el.clear()
el.send_keys(email)
@step(r'I enter "([^"]*)" as password')
def enter_password(step, password):
el = world.browser.find_element(By.ID, 'password')
el.clear()
el.send_keys(password)
@step(r'I click login')
def click_login(step):
world.browser.find_element(By.CSS_SELECTOR, 'button[type="submit"]').click()
@step(r'I should see the dashboard')
def see_dashboard(step):
assert '/dashboard' in world.browser.current_url
@step(r'I should see "([^"]*)"')
def see_text(step, text):
assert text in world.browser.page_source
Terrain (Setup/Teardown — terrain.py)
from lettuce import before, after, world
@before.all
def setup():
world.base_url = 'http://localhost:3000'
@before.each_scenario
def before_scenario(scenario):
pass
@after.each_scenario
def cleanup(scenario):
if hasattr(world, 'browser'):
world.browser.quit()
@after.all
def teardown(total):
print(f"Ran {total.scenarios_ran} scenarios")
Setup: pip install lettuce selenium
Run: lettuce or lettuce features/login.feature
Cloud Execution on TestMu AI
Set environment variables: LT_USERNAME, LT_ACCESS_KEY
# terrain.py
from selenium import webdriver
import os
@before.all
def setup():
lt_options = {
"user": os.environ["LT_USERNAME"],
"accessKey": os.environ["LT_ACCESS_KEY"],
"build": "Lettuce Build",
"platformName": "Windows 11",
"video": True,
"console": True,
}
options = webdriver.ChromeOptions()
options.set_capability("LT:Options", lt_options)
world.browser = webdriver.Remote(
command_executor=f"https://{os.environ['LT_USERNAME']}:{os.environ['LT_ACCESS_KEY']}@hub.lambdatest.com/wd/hub",
options=options,
)
