Question

我正在尝试编写一个测试类，但这是我第一次这样做，所以我从课堂上得到的例子有点迷失。

这是我的Exchange类：

<?php 

//require 'User.php';
require 'Product.php';
require 'EmailSender.php';
require 'DatabaseConnection.php';

class Exchange{

private $dateDebut;
private $dateFin;
private $receiver;
private $product;
private $owner;
private $emailSender;
private $dbConnexion;

function __construct($dateDebut, $dateFin, $receiver, $product, $owner)
{
    $this->dateDebut = $dateDebut;
    $this->dateFin = $dateFin;
    $this->receiver = $receiver;
    $this->product = $product;
    $this->owner = $owner;
    $this->emailSender = new EmailSender();
    $this->dbConnexion = new DatabaseConnection();
}


public function save($dateDebut, $dateFin)
{

    if($this->owner->isValid()){
        $checkOwner = true;
    }

    if($this->receiver->isValid()){
        $checkReceiver = true;
    }

    if($this->product->isValid()){
        $checkProduct = true;
    }

    if(!empty($dateDebut) && $dateDebut > date("Y-m-d")){
        $checkDateDebut = true;
    }

    if(!empty($dateFin) && $dateFin > date("Y-m-d") && $dateFin > $dateDebut){
        $checkDateFin = true;
    }

    if($checkProduct == true && $checkReceiver == true && $checkOwner == true && $checkDateFin == true && $checkDateDebut == true){

            if($this->receiver->age < 19){
                $this->emailSender->sendMail($this->receiver->getEmail(), "Moins de 18 ans");
            }

            // enregistrer en base
            return 12;
    }
    else{
        return false;
    }

}


// Liste des setters

public function setDateDebut($dateDebut)
{
    $this->dateDebut = $dateDebut;
}

public function setDateFin($dateFin)
{
    $this->dateFin = $dateFin;
}

public function setReceiver($receiver)
{
    $this->receiver = $receiver;
}

public function setProduct($product)
{
    $this->product = $product;
}

public function setOwner($owner)
{
    $this->owner = $owner;
}

public function setEmailSender($emailSender)
{
    $this->emailSender = $emailSender;
}

public function setDBConnexion($dbConnexion)
{
    $this->dbConnexion = $dbConnexion;
}


// Liste des getters

public function getDateDebut()
{
    return $this->dateDebut;
}

public function getDateFin()
{
    return $this->dateFin;
}

public function getReceiver()
{
    return $this->receiver;
}

public function getProduct()
{
    return $this->product;
}

public function getOwner()
{
    return $this->owner;
}

public function getEmailSender()
{
    return $this->emailSender;
}

public function getDBConnexion()
{
    return $this->dbConnexion;
}

}

?>

这是我的＆＃34;测试＆＃34;我尝试过的课程。

<?php

要求＆＃39; Exchange.php＆＃39;;

class ExchangeTest extends PHPUnit_Framework_TestCase{

    private $exchange;

    public function testSave()
    {
        $result = $this->exchange->save("2017-11-18", "2017-11-20");
        $this->assertEquals($result, 12);
    }
}

任何有关单一测试的帮助都会很好，谢谢，我还得到了函数数据为空的错误。

看起来你已经定义了一个你没有填充的属性，所以当你去使用它时，没有任何对象可以运行方法并且它出错了。

在大多数单元测试场景中，您希望每个测试尽可能自包含，以避免一个测试导致另一个测试导致级联故障。使这个局部变量应该解决问题：

<div class="tab-pane active" 
           ng-repeat="tab in tabset.tabs" 
              ng-class="{active: tabset.active === tab.index}" uib-tab-content-transclude="tab" style>

我想要创建某种public function testSave() { $exchange = new Exchange(...); $result = $this->exchange->save("2017-11-18", "2017-11-20"); $this->assertEquals($result, 12); }工厂方法，正确初始化exchange()实例，以避免在每次测试中重复大量样板。
