1、markTestSkipped和markTestIncomplete

　　在phpunit中，有两个有用的方法markTestSkipped和markTestIncomplete。它们能允许你编写的单元测试中不单是只有通过和失败两种结果。markTestSkipped能让PHPUNIT不去执行某个已经编写好的测试方法。举个例子说明，比如下面的程序：

php
public function testThisMightHaveADb()
{
$myObject->createObject();
  try {
    $db = new Database();
    $this->assertTrue($db->rowExists());
  } catch (DatabseException $e) {
    $this->markTestSkipped('This test was skipped because there was a database problem');
  }
}
?>

 　　在上面的程序中，是一个连接数据库后，判断数据是否存在的测试方法，但如果考虑数据库的连接异常的话，则应该在抛出异常时，使用markTestSkipped指出该测试方法应该是被忽略的，因为出现了异常，而注意的时，此时有可能你写的代码是正确的，只不过是出现了异常而已，这样phpunit在输出时就不会只是简单的输出fail。

　　而markTestIncomplete也有点类似，但有点不同的是，它是当开发者在编写一个未完成的测试方法时使用的，标记出某个测试方法还没编写完成，同样测试结果也不会是fail，只是告诉phpunit这个测试方法还没编写完成而已，例子如下：

php
public function testAreNotEnoughHours()
{
$this->markTestIncomplete("There aren't enough hours in the day to have my tests go green");
  $trueVariable = true;
  $this->assertTrue($trueVariable);
}
?>

 　　2、更深入了解phpunit中的断言

　　在上一篇文章中，已经基本讲解了一些基本的phpunit中的断言的使用，这里以一个例子，下面是一个类的代码：

php
class Testable
{
  public $trueProperty = true;
  public $resetMe = true;
  public $testArray = array(
    'first key' => 1,
    'second key' => 2
  );
  private $testString = "I do love me some strings";
  public function __construct()
  {
  }
  public function addValues($valueOne,$valueTwo) {
    return $valueOne+$valueTwo;
  }
  public function getTestString()
  {
    return $this->testString;
  }
}
?>

 　　我们编写的单元测试代码初步的框架如下：

php
class TestableTest extends PHPUnit_Framework_TestCase
{
private $_testable = null;
public function setUp()
{
$this->_testable = new Testable();
  }
  public function tearDown()
  {
    $this->_testable = null;
  }
  /** test methods will go here */
}
?>

In the previous article, the setUp method and tearDown method have been introduced. In the setUp method here, a Testable() instance is established and saved in the variable $_testable, while in the tearDown method, the object is destroyed.

Next, start writing some assertions to test, first look at assertTrue and assertFalase:

php
public function testTruePropertyIsTrue()
{
$this->assertTrue($this ->_testable->trueProperty,"trueProperty isn't true");
}
public function testTruePropertyIsFalse()
{
assertFalse($this->_testable->trueProperty, "trueProperty isn't false");}?>
