Symfony2功能測試 - 檢查表內容

Question

我在斷言中只使用過contains()這樣的東西，所以我不確定如何處理像這樣復雜的東西。

假設我有一系列預期答案 - 在這種情況下，它是YES，YES，NO。

所以這意味着有效的，對於第一個和第二個問題，我希望在第三個<td>內看到<span class="glyphicon glyphicon-ok"></span> <td> ，對於我希望看到的第三個問題在第四個<td> 。

這是我的HTML代碼：

<table class="table table-curved">
    <tr>
        <th width="10%">Item</th>
        <th width="60%">Description</th>
        <th width="10%">YES</th>
        <th width="10%">NO</th>
        <th width="10%">NOT APPLICABLE</th>
    </tr>

    <tr>
        <td class="report-table-inner report-centre">1</td>
        <td class="report-table-inner">Check cargo is secure and undamaged.</td>
        <td class="report-centre success"><span class="glyphicon glyphicon-ok"></span></td>
        <td class="report-centre"></td>
        <td class="report-centre"></td>
    </tr>
    <tr>
        <td class="report-table-inner report-centre">2</td>
        <td class="report-table-inner">Is all cargo accounted for.</td>
        <td class="report-centre success"><span class="glyphicon glyphicon-ok"></span></td>
        <td class="report-centre"></td>
        <td class="report-centre"></td>
    </tr>
    <tr>
        <td class="report-table-inner report-centre">3</td>
        <td class="report-table-inner">Is all cargo checked by customs.</td>
        <td class="report-centre"></td>
        <td class="report-centre danger"><span class="glyphicon glyphicon-ok"></span></td>
        <td class="report-centre"></td>
    </tr>
    ...

我該如何為此編寫測試？ 以編程方式迭代<tr>是難的嗎？

謝謝

Answer 1

我想你應該看一下有關Testing和DomCrawler組件的文檔頁面：

• 測試
• DomCrawler組件

有非常簡單的方法可以過濾html或xml內容。

<?php

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class PageTest extends WebTestCase
{
    public function testPage()
    {
        // create a client to get the content of the page
        $client = static::createClient();
        $crawler = $client->request('GET', '/page');

        // retrieve table rows
        $rows = $crawler->filter('.table-curved tr');

        $statesColumnIndex = array(
            // 0 indexed
            'ok' => 2,
            'ko' => 3,
            'na' => 4,
        );

        $expectedValues = array(
            // 0 indexed, row index => [$values]
            1 => ['identifier' => 1, 'state' => 'ok'],
            2 => ['identifier' => 2, 'state' => 'ok'],
            3 => ['identifier' => 3, 'state' => 'ko'],
        );

        foreach ($expectedValues as $rowIndex => $values) {
            // retrieve columns for row
            $columns = $rows->eq($rowIndex)->filter('td');

            // check item identifier
            $identifierColumn = $columns->eq(0);
            $this->assertEquals(
                (string) $values['identifier'],   
                trim($identifierColumn->text())
            );

            // check state
            $stateColumn = $columns->eq($statesColumnIndex[$values['state']]);
            $this->assertEquals(1, $stateColumn->filter('.glyphicon-ok')->count());
        }
    }
}

Answer 3

請注意，我根本不是Symfony，但這是一個使用純PHP DOM的答案; 它需要$ values作為一個數組，其中包含'pass'（跳過此<tr> ）或者哪個列應該包含glyphicon-ok類的索引：

<?php
$data = <<<DATA
<table class="table table-curved">
    <tr>
        <th width="10%">Item</th>
        <th width="60%">Description</th>
        <th width="10%">YES</th>
        <th width="10%">NO</th>
        <th width="10%">NOT APPLICABLE</th>
    </tr>

    <tr>
        <td class="report-table-inner report-centre">1</td>
        <td class="report-table-inner">Check cargo is secure and undamaged.</td>
        <td class="report-centre success"><span class="glyphicon glyphicon-ok"></span></td>
        <td class="report-centre"></td>
        <td class="report-centre"></td>
    </tr>
    <tr>
        <td class="report-table-inner report-centre">2</td>
        <td class="report-table-inner">Is all cargo accounted for.</td>
        <td class="report-centre success"><span class="glyphicon glyphicon-ok"></span></td>
        <td class="report-centre"></td>
        <td class="report-centre"></td>
    </tr>
    <tr>
        <td class="report-table-inner report-centre">3</td>
        <td class="report-table-inner">Is all cargo checked by customs.</td>
        <td class="report-centre"></td>
        <td class="report-centre danger"><span class="glyphicon glyphicon-ok"></span></td>
        <td class="report-centre"></td>
    </tr>
</table>
DATA;


$dom = new DOMDocument();
$dom->loadXML($data);
$xpath = new DOMXPath($dom);
$values = ['pass', 2, 2, 3];
$idx = 0;
foreach($xpath->query('//tr') as $tr) {
  if ($values[$idx] != 'pass') {
    $tds = $tr->getElementsByTagName('td');
    $td = $tds->item($values[$idx]);
    if ($td instanceof DOMNode && $td->hasChildNodes()) {
      if (FALSE !== strpos($td->firstChild->getAttribute('class'), 'glyphicon-ok')) {
          echo "Matched on ", $tds->item(1)->textContent, "\n";
      } else {
          echo "Not matched on ", $tds->item(1)->textContent, "\n";
      }
    }
  }
  ++$idx;
}
