如何替换 URL 并在 behat 中传递数据

Question

我只是在学习，如果这是非常基础的，我深表歉意。我有这样的场景：

Scenario: Create Task
    Given I have the JSON payload:
    """
    {
            "task_list_id" : 3,
            "title" : "From Behat",
            "display_order" : 1
    }
    """
    When I send a POST request to task
    Then one SQL ident is created

Scenario: Get the Task
  When I send a GET request to "tasklist/{id}/tasks"
  Then The response code should be 200
  And The response content type should be "application/json"

所以第一个场景建立连接，然后 JSON 返回一个整数值。我现在希望 that 值被替换到 URL 具有 {id} 占位符的下一个场景中。

我尝试在第一个场景的 FeatureContext.php 文件中将 $this->output 设置为正文（返回的整数），然后在第二个场景中做了一个 preg_replace 来更改 {id } 到整数。似乎当第二个场景是运行时，输出在调用该场景之前被清空。

这些是我的上下文方法：

  /**
   * @Then One SQL ident is created
   */
  public function theResponseBodyShouldBeAnInteger() {
    $this->theResponseContentTypeShouldBe('application/json');
    $this->theResponseCodeShouldBe(201);

      $body = $this->response->getBody()->getContents();
    if (!ctype_digit($body)) {
            throw New Exception(sprintf('Expected integer response but got "%s".', $body));
    }

    $this->output = $body;
    echo "Output is '$this->output'\n";
  }

  /**
   * @When I send a :method request to :uri
   *
   * @param $method
   * @param $uri
   */
  public function iSendARequestTo($method, $uri)
  {
    echo "Output is '$this->output'\n";
    $uri = str_replace('{id}', $this->output, $uri);

    try {
            if ($method == 'POST' || $method == 'PATCH') {
                    $this->response = $this->client->request($method, $uri, ['json' => $this->requestPayload]);
            } else {
                    $this->response = $this->client->request($method, $uri);
            }
    } catch (GuzzleHttp\Exception\ClientException $ex) {
            throw new Exception($uri . "\n" . $ex->getResponse()->getBody()->getContents());
    }
  }

Answer 1

当然是空白，场景是而且应该是独立的，你在第一个场景中保存的东西在场景完成后都会丢失。

执行此操作的一种方法是写入文件并从文件中读取。

无论如何我看到第一个场景的验证包括第二个场景的验证，唯一的区别是在第一个场景中你保存了响应的 body，这不是一个好主意并且在验证步骤中保存数据不是一个好习惯。

尽量重复使用。

Scenarios hold be independent.You should able to run the second scenario without the first one.

高级示例，仅供参考：

Scenario: Api - check response of the created task
   Given I have the JSON payload
   When I create a task using POST request -> create request, make sure is successful and save response
   And I send a GET request to created task -> use saved response to do what you need
   Then the response code should be 200
   And the response code should be "application/json"

另一个例子：

Scenario: Api - check response of the created task
   Given I have have a task based on JSON: -> create request, make sure is successful and save response
   When I send a GET request to created task -> use saved response to do what you need
   Then the response code should be 200
   And the response code should be "application/json"

这些只是一些示例，我不知道其功能，我相信您可以做得更好，始终在创建步骤时牢记您的项目业务语言，以便以后理解它们。

任务列表方法 您需要确保您有一个 taskList，这是必需的，您需要检查 taskList 是否可用（例如按标题），如果是，则什么都不做，创建任务列表。
