php phpunit two sharp weapon unit and test go deep usage

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 */
}
?>

   在上一篇文章中,已经介绍了setUp方法和tearDown方法,这里的setUp方法中,建立了Testable()实例并保存在变量$_testable中,而在tearDown方法中,销毁了该对象。

  接下来,开始编写一些断言去测试,首先看assertTrue和assertFalase:

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