前端测试自动化工具(一)

selenium

selenium 分为好几个系列

• Selenium IDE
• Selenium Server (formerly the Selenium RC Server)
• Selenium Client & WebDriver Language Bindings

详细的说明介绍在这里 简单来说, selenium ide 是 firefox 浏览器上的一款插件, 可以记录测试员的一系列操作, 并可以根据要求生成一系列命令和特定的脚本程序

(看个人喜好).

selenium rc 是用来运行selenium 脚本程序的..

webdriver 的说明在这里

selenium webdriver & python

开发人员自己要写测试用例, 这是个很好的习惯..本人推荐python系列. windows 下安装过程如下:

• python
• setuptools , pip
• pip install -U selenium
• selenium-server-standalone-XXX.jar

本人安装测试的时候折腾了好久, 不想让大家也这样折腾一次. 所以整理了下, 打了个包供大家下载.

包内容如下: firefox , selenium-ide, chromedriver, iedriver, selenium-server-standalone-XXX.jar, pip, setuptools.

python的安装, 请去官网上看说明. 另外个安装说明在这里

用例测试

以好康网的登陆过程为例一系列流程下来, selenium ide 生成的命令如下:

然后可以导出为python rc 或者 python webdriver 脚本, 可以手动修改脚本再运下.

python webdriver的版本如下:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.common.exceptions import NoSuchElementException
import unittest, time, re

class Login(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = "http://staging.fever38.com/"
        self.verificationErrors = []
        self.accept_next_alert = True

    def test_login(self):
        driver = self.driver
        driver.get(self.base_url + "/")
        driver.find_element_by_css_selector("b.fb-login").click()

        driver.switch_to_window(driver.window_handles[-1])
        WebDriverWait(driver, 10).until(lambda x: x.find_element_by_id("email"))
        driver.find_element_by_id("email").clear()
        driver.find_element_by_id("email").send_keys("your email")
        driver.find_element_by_id("pass").clear()
        driver.find_element_by_id("pass").send_keys("your password")
        driver.find_element_by_id("persist_box").click()


    def is_element_present(self, how, what):
        try: self.driver.find_element(by=how, value=what)
        except NoSuchElementException, e: return False
        return True

    def is_alert_present(self):
        try: self.driver.switch_to_alert()
        except NoAlertPresentException, e: return False
        return True

    def close_alert_and_get_its_text(self):
        try:
            alert = self.driver.switch_to_alert()
            alert_text = alert.text
            if self.accept_next_alert:
                alert.accept()
            else:
                alert.dismiss()
            return alert_text
        finally: self.accept_next_alert = True

    def tearDown(self):
        self.driver.quit()
        self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
    unittest.main()

python selenium rc 的版本如下:

from selenium import selenium
import unittest, time, re

class login2(unittest.TestCase):
    def setUp(self):
        self.verificationErrors = []
        self.selenium = selenium("localhost", 4444, "*chrome", "http://staging.fever38.com/")
        self.selenium.start()

    def test_login2(self):
        sel = self.selenium
        sel.open("/")
        sel.click("css=b.fb-login")
        sel.wait_for_pop_up("f3da5628edf910a", "30000")
        sel.select_window("name=_e_0pS1")
        sel.type("id=email", "your email")
        sel.type("id=pass", "your password")
        sel.click("id=persist_box")
        sel.click("id=u_0_1")
        sel.wait_for_page_to_load("30000")

    def tearDown(self):
        self.selenium.stop()
        self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
    unittest.main()

selenium-server 启动

@echo on
cmd.exe /k "%1" java -jar e:\selenium-server-standalone-2.33.0.jar
