README

有时候为具有多个依赖关系的类编写新的单元测试可能会很繁琐，因此这个包旨在简化Magento2单元测试的创建。命令读取源文件并为指定的类生成基本的单元测试结构。如果单元测试已存在，则不会发生任何操作。测试类将放置在测试对象类模块的app/code/Vendor/Module/Test/Unit/...目录下。

如何安装

composer require olmer/magento-unit-tests-generator --dev
php bin/magento cache:clean
php bin/magento setup:di:compile

如何为特定类生成单元测试

php bin/magento dev:tests:generate-unit /app/code/Vendor/Module/path/to/file.php

示例

源代码类

<?php
declare(strict_types=1);

namespace Vendor\Reorder\Helper;

class Reorder
{
    public function __construct(
        Context $context,
        OrderRepositoryInterface $orderRepository,
        SearchCriteriaFactory $criteria,
        FilterGroupFactory $filterGroup,
        FilterFactory $filter,
        OrderFactory $orderFactory,
        SortOrderFactory $sortOrderFactory
    ) {
        $this->orderRepo = $orderRepository;
        $this->searchCriteriaFactory = $criteria;
        $this->filterGroupFactory = $filterGroup;
        $this->filterFactory = $filter;
        $this->orderFactory = $orderFactory;
        $this->sortOrderFactory = $sortOrderFactory;
    }

    public function getFilename()
    {
        ...
    }
    
    public function getLastShippedOrder()
    {
        ...
    }
}
