我正在測試Web爬網程序腳本。我正在使用php內置webserver在本地測試頁面。Behat:完成測試後無法終止Web服務器進程
我可以啓動服務器,但我不能殺死進程,因爲它已經被殺死(我得到了我設置的例外Could not kill the testing web server
)。
這裏是我的嘗試:
<?php
use Behat\Behat\Tester\Exception\PendingException;
use Behat\Behat\Context\Context;
use Behat\Behat\Context\SnippetAcceptingContext;
use Behat\Gherkin\Node\PyStringNode;
use Behat\Gherkin\Node\TableNode;
use Behat\Behat\Hook\Scope\BeforeScenarioScope;
use Behat\Behat\Hook\Scope\AfterScenarioScope;
/**
* Defines application features from the specific context.
*/
class FeatureContext implements Context, SnippetAcceptingContext
{
const TESTING_BASE_URL = 'http://127.0.0.1:6666';
const TESTING_DIR = '/tmp/testDirectory';
private $pid;
/**
* Initializes context.
*
* Every scenario gets its own context instance.
* You can also pass arbitrary arguments to the
* context constructor through behat.yml.
*/
public function __construct()
{
}
/**
* @BeforeScenario
*/
public function before(BeforeScenarioScope $scope)
{
// Create testing directory holding our pages
if (!is_dir(self::TESTING_DIR)) {
if (!mkdir(self::TESTING_DIR)) {
throw new \Exception('Cannot create the directory for testing');
}
}
// Start the testing server
$command = sprintf(
'php -S %s -t $%s >/dev/null 2>&1 & echo $!',
escapeshellarg(self::TESTING_BASE_URL),
escapeshellarg(self::TESTING_DIR)
);
$output = [];
exec($command, $output, $return_var);
if ($return_var !== 0) {
throw new \Exception('Cannot start the testing web server');
}
$this->pid = (int)$output[0];
echo sprintf(
'Testing web server started on %s with PID %s %s %s',
self::TESTING_BASE_URL,
(string)$this->pid,
PHP_EOL,
PHP_EOL
);
}
/**
* @AfterScenario
*/
public function after(AfterScenarioScope $scope)
{
// ... kill the web server
$output = [];
exec('kill ' . (string) $this->pid, $return_var);
if ($return_var !== 0) {
throw new \Exception('Could not kill the testing web server (PID ' . (string) $this->pid . ')');
}
echo 'Testing web server killed (PID ', (string) $this->pid, ')', PHP_EOL, PHP_EOL;
// ... remove the test directory
$o = [];
exec('rm -rf ' . escapeshellarg(self::TESTING_DIR), $o, $returnVar);
if ($returnVar !== 0) {
throw new \Exception('Cannot remove the testing directory');
}
}
// ...
}
我也嘗試就像把它全部在構造函數中,使用register_shutdown_function
,沒有任何成功的各種事情。
我錯過了什麼?有關我如何解決這個問題的任何想法?
而不僅僅是「不關心殺死服務器進程」(因爲對我來說,當我嘗試殺死進程時,看起來它已經消失了,因此錯誤,當我在命令上發出ps aux | grep php
時找不到它在運行behat後線),是不是「乾淨」殺了它,因爲我參加?
