driver= webdriver.Chrome()
driver.get("https://mail.126.com/")
time.sleep(3)
####登陸
driver.switch_to.frame("x-URS-iframe")
user_name = driver.find_element_by_xpath('//*[@name="email"]')
#將xxxxxxx替換為自己的使用者名稱
user_name.send_keys('xxxxxxx')
pass_word = driver.find_element_by_xpath('//*[@name="password"]')
#將11111111111替換為自己的密碼
pass_word.send_keys('11111111111')
button = driver.find_element_by_id("dologin")
button.click()
driver.switch_to.default_content()
time.sleep(3)

####寫郵件
wait = WebDriverWait(driver,10,0.2)
##wait.until(EC.visibility_of_element_located((By.XPATH,"//span[text()='傳送']")))
wait.until(EC.visibility_of_element_located((By.XPATH,"//a[contains(text(),'退出')]")))

driver.execute_script("document.getElementsByTagName('body')[0].innerHTML='<b>郵件的正文內容<b>;'")
driver.switch_to.default_content()

##傳送
driver.find_element_by_xpath('//span[text()="傳送"]').click()
time.sleep(5)
assert '傳送成功' in driver.page_source
logout_link=driver.find_element_by_xpath("//a[text()='退出']")
time.sleep(3)

driver.quit()
