当行为测试和字段具有相同名称时处理填充字段的最佳方法

Question

我有一个网站的登录页面，该网站包含三种类型的用户。用户单击 his/her 类型，然后会出现 un/pw 字段，具体取决于用户单击的类型。然而，在页面源代码中，所有三种形式都存在，但根据选择的类型，有两种形式被隐藏。我正在尝试编写一个 behat 测试来测试记录每种类型的用户。我的 behat 测试如下所示：

 @javascript @core
 Feature: Secure Login
   As a User
   I expect to be asked for my credentials
   So that I can use the system securely

  Background:
     Given I am logged out

     Scenario: Failed User1 Login
     When I go to user1 interface
     When I submit incorrect user1 credentials
     Then I should stay logged out
     And I should see "The username or password entered does not match our records."

   Scenario: Successful User1 Login
     When I go to user1 interface
     When I submit correct user1 credentials
     Then I should be logged in to user1 interface

   Scenario: Failed User2 Login
     When I go to user2 interface
     When I submit incorrect user2 credentials
     Then I should stay logged out
     And I should see "The username or password entered does not match our records."

   Scenario: Successful User2 Login
     When I go to user2 interface
     When I submit correct user2 credentials
     Then I should be logged in to user2 interface

当我查看页面源代码时，这是我看到的表单内容：

<form id='user1' name='user1' method="post" role="form">
    <input type="hidden" name="subsystem" value="user1"/>
    <label for="un1" class="label">Username</label>
    <div id="un_inst1"class="label_instruction"></div>
    <input autocapitalize="off" id="un1" autocorrect="off" type="text" name="username" value="" style="margin-bottom: 10px" aria-describedby="un_inst1">
    <label for="pw1" class="label">Password</label>
    <div id="pw_inst1"class="label_instruction"></div>
    <input type="password" id="pw1" name="password" style="margin-bottom: 10px;" aria-describedby="pw_inst1">
    <div class="login_buttons">
        <input type="submit" value="Go" class="btn_go input-submit">
        <input type="reset" class="btn_reset input-reset" value="Reset">
        <br/>
    </div>
</form>
<form id='user2' name='user2' method="post" role="form">
    <input type="hidden" name="subsystem" value="resident"/>
    <div class="usr-login label">Resident Login</div>
    <label for="un2" class="label">Username</label>
    <div id="un_inst2"class="label_instruction"></div>
    <input autocapitalize="off" autocorrect="off" type="text" id="un2" name="username" value="" style="margin-bottom: 10px" aria-describedby="un_inst2">
    <label for="pw2" class="label">Password</label>
    <div id="pw_inst2"class="label_instruction"></div>
    <input type="password" id="pw2" name="password" style="margin-bottom: 10px;" aria-describedby="pw_inst2">
    <div class="login_buttons">
        <input type="submit" value="Go" class="btn_go input-submit">
        <input type="reset" class="btn_reset input-reset" value="Reset">
        <br/>
    </div>
</form>

在我的 featurecontext 文件中，我有这些函数：

public function iSubmitIncorrectCredentials($interface)
{
    $button ='Go';
    return $this->login("tester" . time(), "bar", $button);
}

private function login($username, $password, $btn) 
{
    $this->fillField('username', $username);
    $this->fillField('password', $password);
    $this->pressButton($btn);
}

其中 $interface 用于 user1 或 user2。我遇到的问题是 user1 的测试通过了，但是当我进行 user2 测试时，我得到这个错误：

{"errorMessage":"Element is not currently interactable and may not be manipulated","request":{"headers":{"Accept":"application/json;charset=UTF-8","Content-Length":"36","Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1:8643"},"httpVersion":"1.1","method":"POST","post":"{\"value\":[\"tester1479232631\ue004\"]}","url":"/value","urlParsed":{"anchor":"","query":"","file":"value","directory":"/","path":"/value","relative":"/value","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/value","queryKey":{},"chunks":["value"]},"urlOriginal":"/session/ea0f7000-ab5c-11e6-acb9-5946ec8fdb06/element/:wdc:1479232631203/value"}} (WebDriver\Exception\InvalidElementState)

我认为正在发生的事情是 fillField() 试图找到用户名字段，但有两个，所以对于 user1，测试有效，但对于 user2，我得到错误。除了更改 un/pw 字段的名称外，我还想获得有关如何处理此问题的一些建议。谢谢

Answer 1

您需要为每个表单设置不同的选择器。您可以通过几种方式做到这一点：

对于前两种方法，您需要使用另一种方法来填充元素并单击字段，因为您将使用 css 选择器。
例如：找到元素-> click() 找到元素-> setValue()

1) 使用不同的选择器为每种类型创建一个方法

 loginWithUser1($username, $password){...}
 loginWithUser2($username, $password){...}
 loginWithUser3($username, $password){...}

您将需要对以下元素使用 css 选择器：

#user1 input[name=username]
#user1 input[name=password]

2) 使用相同的方法和 build/read 基于参数

的数组选择器

 login($username, $password, $role)
 {

 }

3) 使用页面对象功能
此选项将使用与第二个选项相同的方法，但不是从数组中读取选择器，而是使用 getElement() 方法并在该对象上使用您需要的方法。请在此处查看示例 working with elements

我建议尝试最后一个选项，如果您不能尝试第二个选项。

Tip: Avoid passing parameters in the method that you don't need like $btn from your login method.The method should know about the button element, you need to pass data only.
