我正在尝试像这样在数据库单元中创建初始数据库状态...

public function getDataSet() {
        $primary = new \PHPUnit\DbUnit\DataSet\CompositeDataSet();
        $fixturePaths = [
            "test/Seeds/Upc/DB/UpcSelect.xml",
            "test/Seeds/Generic/DB/ProductUpcSelect.xml"
        ];
        foreach($fixturePaths as $fixturePath) {
            $dataSet = $this->createXmlDataSet($fixturePath);
            $primary->addDataSet($dataSet);
        }
        return $primary;
    }

然后在我的查询之后，我试图调用这个用户定义的函数......

protected function compareDatabase(String $seedPath, String $table) {
    $expected = $this->createFlatXmlDataSet($seedPath)->getTable($table);
    $result = $this->getConnection()->createQueryTable($table, "SELECT * FROM $table");
    $this->assertTablesEqual($expected, $result);
  }

这里的想法是，我有一个初始数据库状态，运行我的查询，然后将实际表状态与代表我期望表外观的 XML 数据集进行比较。这个过程在PHPUnit 的 DBUnit 文档中有描述，但我一直抛出异常......

PHPUnit\DbUnit\InvalidArgumentException: There is already a table named upc with different table definition

测试示例...

public function testDeleteByUpc() {
    $mapper = new UpcMapper($this->getPdo());
    $mapper->deleteByUpc("someUpcCode1");
    $this->compareDatabase("test/Seeds/Upc/DB/UpcAfterDelete.xml", 'upc');
  }

我似乎在关注文档……这应该怎么做？

这实际上与创建第二个 XML 数据集无关。抛出此异常是因为我在getDataSet()方法中加载的两个固定装置都有upc.
