在运行PHPUnit测试时,我希望能够转储输出,以便调试一两个东西。
我已经尝试了以下(类似于PHPUnit手册的例子);
class theTest extends PHPUnit_Framework_TestCase
{
/**
* @outputBuffering disabled
*/
public function testOutput() {
print_r("Hello World");
print "Ping";
echo "Pong";
$out = "Foo";
var_dump($out);
}
}
结果如下:
PHPUnit @package_version@ by Sebastian Bergmann.
.
Time: 0 seconds, Memory: 3.00Mb
OK (1 test, 0 assertions)
注意,这里没有预期的输出。
我使用的是2011年9月19日的git回购的HEAD版本。
php -version输出:
$ php -version
PHP 5.2.9 (cli) (built: Dec 8 2010 11:36:37)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies

是否有什么我做错了,或者这是一个潜在的PHPUnit错误?
下面是PHPUnit 4.x中用于打印调试消息的几个有用方法:
syslog(LOG_DEBUG, "Debug: Message 1!");
More practical example:
syslog(LOG_DEBUG, sprintf("%s: Value: %s", __METHOD__, var_export($_GET, TRUE)));
Calling syslog() will generate a system log message (see: man syslog.conf).
Note: Possible levels: LOG_DEBUG, LOG_INFO, LOG_NOTICE, LOG_WARNING, LOG_ERR, etc.
On macOS, to stream the syslog messages in realtime, run:
log stream --level debug --predicate 'processImagePath contains "php"'
fwrite(STDERR, "LOG: Message 2!\n");
Note: The STDERR constant is not available if reading the PHP script from stdin. Here is the workaround.
Note: Instead of STDERR, you can also specify a filename.
file_put_contents('php://stderr', "LOG: Message 3!\n", FILE_APPEND);
Note: Use this method, if you don't have STDERR constant defined.
register_shutdown_function('file_put_contents', 'php://stderr', "LOG: Message 4!\n", FILE_APPEND);
Note: Use this method, if you'd like to print something at the very end without affecting the tests.
要转储变量,使用var_export(),例如:值:。var_export($some_var, TRUE)。“\ n”。
若要仅在verbose或调试模式下打印上述消息,请参见:是否有一种方法可以判断在测试中——debug或——verbose是否传递给了PHPUnit ?
如果测试输出是测试本身的一部分,请查看:测试输出文档页面。
在某些情况下,可以使用类似的东西向控制台输出一些内容
class yourTests extends PHPUnit_Framework_TestCase
{
/* Add Warnings */
protected function addWarning($msg, Exception $previous = null)
{
$add_warning = $this->getTestResultObject();
$msg = new PHPUnit_Framework_Warning($msg, 0, $previous);
$add_warning->addWarning($this, $msg, time());
$this->setTestResultObject($add_warning);
}
/* Add errors */
protected function addError($msg, Exception $previous = null)
{
$add_error = $this->getTestResultObject();
$msg = new PHPUnit_Framework_AssertionFailedError($msg, 0, $previous);
$add_error->addError($this, $msg, time());
$this->setTestResultObject($add_error);
}
/* Add failures */
protected function addFailure($msg, Exception $previous = null)
{
$add_failure = $this->getTestResultObject();
$msg = new PHPUnit_Framework_AssertionFailedError($msg, 0, $previous);
$add_failure->addFailure($this, $msg, time());
$this->setTestResultObject($add_failure);
}
public function test_messages()
{
$this->addWarning("Your warning message!");
$this->addError("Your error message!");
$this->addFailure("Your Failure message");
}
/* Or just mark test states! */
public function test_testMarking()
{
$this->markTestIncomplete();
$this->markTestSkipped();
}
}
