Zend framework Zend_Test_PHPUnit如何打印异常/输出？

如何在测试用例中回显来自控制器操作的html/xml输出

下面是我的测试用例：

public function testCreateAccountIsASuccessfulRequest()
{
    $this->dispatch('/v2/user/create-account');

    $this->assertFalse($this->response->isException());

    $this->assertNotRedirect();
}

它在命令行中打印此命令：

test# /usr/local/bin/phpunit --verbose Controllers_UserControllerTest.php
PHPUnit 3.6.10 by Sebastian Bergmann.

F

Time: 0 seconds, Memory: 12.50Mb

There was 1 failure:

1) Controllers_UserControllerTest::testCreateAccountIsASuccessfulRequest
Failed asserting that true is false.

/path/to/tests/Controllers/UserControllerTest.php:17
/usr/local/bin/phpunit:46

FAILURES!
Tests: 1, Assertions: 1, Failures: 1.
test#

我不确定实际的例外情况是什么。怎么看？另外，如何查看控制器操作的实际输出？那么它发送到浏览器的HTML/XML呢？

天哪，我今天很慢：

public function testCreateAccountIsASuccessfulRequest()
{
    $this->dispatch('/v2/user/create-account');

    echo $this->getResponse()->getBody();

    $this->assertFalse($this->response->isException());

    $this->assertNotRedirect();
}
