PHPUnit 自定 TestSuite 輸出樣式，輸出為 HTML 網頁
PHPUnit 預置了一個純文字型式的 TextUI Runner，在大多數情形下，它足夠應付我們的需求。不過，當我想要把 TestSuite 放到專案網頁上，讓小組成員 - 特別是 PM - 可以上網查看立即的測試結果時，那個文字型式的 TextUI Runner 就顯得太簡略了。至少要把測試工作及結果輸出成 HTML 的條列式清單，最好還加上顏色區別成功或失敗。
所幸 PHPUnit 提供了良好的擴充性，要自定一個可以將測試內容輸出為 HTML 網頁的 HTML Runner 相當簡單。
自定輸出樣式的方法很多，我選擇透過擴展 PHPUnit_Framework_TestListener 來實現。See also: Implement PHPUnit_Framework_TestListener.
另一方面，我將測試案例清單放置在另一個檔案中。在本例中，測試案例清單之文件名稱為 UnitTestSuiteList.php。
<?php
/**
* 測試案例清單。
*/
$testCases = array(
'AbcTest.php',
'XyzTest.php'
);
?>HTML Runner, UnitTestSuite.php
<?php
if (!defined('PHPUnit_MAIN_METHOD')) {
define('PHPUnit_MAIN_METHOD', '');
}
//測試案例清單
require_once 'UnitTestSuiteList.php';
require_once 'PHPUnit/Framework.php';
class HtmlTestListener implements PHPUnit_Framework_TestListener {
protected $lastTestStatus;
private function _name(PHPUnit_Framework_Test $test)
{
$name = $test->getName();
if (preg_match_all('/[A-Z][a-z0-9]+/', $name, $words)) {
$words = $words[0];
$showName = array_shift($words);
foreach ($words as $word) {
$showName .= ' ' . strtolower($word);
}
return $showName;
}
return $name;
}
public function addError(PHPUnit_Framework_Test $test,
Exception $e,
$time)
{
$this->lastTestStatus = 'e';
}
public function addFailure(PHPUnit_Framework_Test $test,
PHPUnit_Framework_AssertionFailedError $e,
$time)
{
$this->lastTestStatus = 'f';
}
public function addIncompleteTest(PHPUnit_Framework_Test $test,
Exception $e,
$time)
{
$this->lastTestStatus = 'i';
}
public function addSkippedTest(PHPUnit_Framework_Test $test,
Exception $e,
$time)
{
$this->lastTestStatus = 's';
}
public function startTest(PHPUnit_Framework_Test $test)
{
$this->lastTestStatus = 'p'; //pass
}
public function endTest(PHPUnit_Framework_Test $test, $time)
{
echo '<li>[';
switch ( $this->lastTestStatus ) {
case 'e':
echo '<span class="error">E</span>';
break;
case 'f':

break;
case 'i':
echo '<span class="incomplete">I</span>';

case 's':
echo '<span class="skipped">S</span>';
break;
default:
echo '<span class="pass">P</span>';
break;
}
echo ']', $this->_name($test), "</li>\n";
}
public function startTestSuite(PHPUnit_Framework_TestSuite $suite)
{
if ('' != $suite->getName())
printf("<div class='test_suite'>%s:</div><ul>\n", $suite->getName());
}
public function endTestSuite(PHPUnit_Framework_TestSuite $suite)
{
if ('' != $suite->getName())
printf("</ul></div>\n");
}
}
?>
