web项目的登录窗口的测试

今天咱们继续接上上一篇所讲，开始用项目来练手：给出以下图：

 测这个登录窗口：其实比较好测，拿最简单容易想到的，就是什么账号密码均正确；账号为空；密码为空；账号未授权；密码错误(账号已授权)等等，那么我们怎么来用selenium来实现呢？

import unittest
from selenium.webdriver import Chrome
from selenium.webdriver.common.by import By
class TestLogin(unittest.TestCase):

    def setUp(self):
        """登录的前置：启动浏览器，访问登录页面"""
        self.driver = Chrome()
        self.driver.implicitly_wait(10)
        # 打开前程贷的登录页面
        self.driver.get("http://8.129.91.152:8765/Index/login.html")

    def test_login_pass(self):
        """登录成功"""
        # 输入账号
        self.driver.find_element(By.XPATH, '//input[@placeholder="手机号"]').send_keys('18684720553')
        # 输入密码
        self.driver.find_element(By.XPATH, '//input[@placeholder="密码"]').send_keys('python')
        # 点击登录
        self.driver.find_element(By.XPATH, "//button[text()='登录']").click()
        # 断言是否成功
        try:
            ele = self.driver.find_element(By.XPATH, '//a[text()="我的帐户[python]"]')
        except:
            ele = False
        self.assertTrue(ele)def test_login_pwd_is_none(self):
        """密码为空"""
        # 输入账号和密码
        self.driver.find_element(By.XPATH, '//input[@placeholder="手机号"]').send_keys('18684720553')
        self.driver.find_element(By.XPATH, '//input[@placeholder="密码"]').send_keys('')
        # 点击登录
        self.driver.find_element(By.XPATH, "//button[text()='登录']").click()
        # 断言是否成功
        excepted = "请输入密码"
        # 获取报错信息的文本
        res = self.driver.find_element(By.XPATH, '//div[@class="form-error-info"]').text
        self.assertEqual(excepted, res)

    def test_login_phone_is_none(self):
        """手机号为空"""
        # 输入账号和密码
        self.driver.find_element(By.XPATH, '//input[@placeholder="手机号"]').send_keys('')
        self.driver.find_element(By.XPATH, '//input[@placeholder="密码"]').send_keys('python')
        # 点击登录
        self.driver.find_element(By.XPATH, "//button[text()='登录']").click()
        # 断言是否成功
        excepted = "请输入手机号"
        # 获取报错信息的文本
        res = self.driver.find_element(By.XPATH, '//div[@class="form-error-info"]').text
        self.assertEqual(excepted, res)

一开始简单的列出了三种场景，也能跑通，但是，有个问题，下面两个方法好像差不多，咱们能不能优化一下呢？

 如何优化？附上代码，并截图解析

import unittest
from selenium.webdriver import Chrome
from selenium.webdriver.common.by import By
from unittestreport import ddt, list_data

login_data_is_none = [
    {"title": "密码为空", "phone": "18684720553", "pwd": "", "expected": "请输入密码"},
    {"title": "手机号为空", "phone": "", "pwd": "python", "expected": "请输入手机号"},
]

@ddt
class TestLogin(unittest.TestCase):

    def setUp(self):
        """登录的前置：启动浏览器，访问登录页面"""
        self.driver = Chrome()
        self.driver.implicitly_wait(10)
        # 打开前程贷的登录页面
        self.driver.get("http://8.129.91.152:8765/Index/login.html")

    def test_login_pass(self):
        """登录成功"""
        # 输入账号
        self.driver.find_element(By.XPATH, '//input[@placeholder="手机号"]').send_keys('18684720553')
        # 输入密码
        self.driver.find_element(By.XPATH, '//input[@placeholder="密码"]').send_keys('python')
        # 点击登录
        self.driver.find_element(By.XPATH, "//button[text()='登录']").click()
        # 断言是否成功
        try:
            ele = self.driver.find_element(By.XPATH, '//a[text()="我的帐户[python]"]')
        except:
            ele = False
        self.assertTrue(ele)

    @list_data(login_data_is_none)
    def test_login_data_is_none(self, case):
        # 输入账号和密码
        self.driver.find_element(By.XPATH, '//input[@placeholder="手机号"]').send_keys(case['phone'])
        self.driver.find_element(By.XPATH, '//input[@placeholder="密码"]').send_keys(case['pwd'])
        # 点击登录
        self.driver.find_element(By.XPATH, "//button[text()='登录']").click()
        # 断言是否成功
        expected = case["expected"]
        # 获取报错信息的文本
        res = self.driver.find_element(By.XPATH, '//div[@class="form-error-info"]').text
        self.assertEqual(expected, res)

 然后运行run.py文件，也可以跑的通

 然后，这个登录有一个场景，就是账号未授权时，会给出toast弹窗提示，这种的又如何来展开呢？

这种，第一步就是要正确写出toast弹窗的xpath定位表达式，怎么来具体操作呢？

 然后获取文本信息，写出定位表达式

 然后直接上代码

    def test_login_toast_error(self):
        """账号未授权"""
        # 输入账号
        self.driver.find_element(By.XPATH, '//input[@placeholder="手机号"]').send_keys('18684720552')
        # 输入密码
        self.driver.find_element(By.XPATH, '//input[@placeholder="密码"]').send_keys('python')
        # 点击登录
        self.driver.find_element(By.XPATH, "//button[text()='登录']").click()

        # 获取toast弹窗的内容
        expected = "此账号没有经过授权，请联系管理员!"
        WebDriverWait(self.driver, 15, 0.5).until(
            EC.visibility_of_element_located((By.XPATH, '//div[@class="layui-layer-content"]'))
        )
        res = self.driver.find_element(By.XPATH, '//div[@class="layui-layer-content"]').text
        self.assertEqual(expected, res)

注意：记得要导入显示等待和EC

 因此，这种出现弹窗的，咱们也可以合理的处理好。
