Third party tools and framework integration

Introduction to agile development testing concept

BDD： Behavior driven development , Also known as acceptance test driven development （ATDD）. Based on users Story Agile testing or instantiation requirements .
CI： Continuous integration framework

be based on BDD Test tools

python Many of the tools in can implement BDD, There are two main tools Behave and Lettuce.

Behave

pip install behave

To write feature Document principles ：GWT（Given-When-Then）

• Given： Set the preconditions for the execution of a scenario
• When： Contains the operations to be performed by a scenario
• Then： Contains the results of a scenario execution
  notes ： A scene can have multiple when and then.

step Definition

feature File scene outline step It needs to be defined separately .
step The definition file is saved in feature Subdirectory of the path where the file is located steps Next .
for example ：

from behave import *
@given('I am on home page')
def step_i_am_on_home_page(context):
　　context.driver.get("http://demo.magentocommerce.com
/")
@when('I search for {text}')
def step_i_search_for(context, text):
　　search_field = context.driver.find_element_by_name(
"q")
　　search_field.clear()
　　# enter search keyword and submit
　　search_field.send_keys(text)
　　search_field.submit()
@then('I should see list of matching products in search
results')
def step_i_should_see_list(context):
　　products = context.driver.\
　　　　find_elements_by_xpath("//h2[@class='product-nam
e']/a")
　　# check count of products shown in results
　　assert len(products) > 0

Environment configuration

function feature Before , You need to create an environment configuration file , To configure Behave Common configuration , as well as step Between or step Define shared code between files .

Usually in feature Create a new environment configuration file in the file directory environment.py, add to before_all() and after_all() Method , These two methods are respectively in feature Run before and after execution .

from selenium import webdriver
def before_all(context):
　　context.driver = webdriver.Chrome()
　　
def after_all(context):
　　context.driver.quit()

perform behave

Get into bbd Under the document , And then execute “behave” command .
Behave Show results at three levels . Namely feature、scenario and step The number of passes and failures at each level .

Continuous integration Jenkins

Jekins yes Java Write continuous integration （CI） service , Come of Hudson project .
The service support includes git、SVN And other version control tools .
Jekins In addition to building software functions 、 It can also be used to build an automated test environment .
