php - 测试计数大于 CodeCeption 中数据提供者的数据计数

Question

我在 CodeCeption 中有一个 Cest，它使用 dataProvider:

<?php


class MyCest
{
    /**
     * @param \Codeception\Example $example
     * @dataProvider MyDataProvider
     */
    public function MyTestCase(Codeception\Example $example)
    {
        echo "Name: ", $example['name'], ", Age: ", $example['age'];
    }

    public function MyDataProvider() {
        $data = [
            ["name" => 'Alice', "age" => 20],
            ["name" => 'Tom', "age" => 35],
            ["name" => 'Bob', "age" => 60],
        ];
        return $data;
    }
}

如您所见，它返回 3 个数据项，但是当我运行测试时，日志显示我们有 4 个测试:

✔ MyCest: My test case | "Tom",35 (0.00s)m, Age: 35

OK (4 tests, 0 assertions)

我评论了PHPUnit DataProvider documentation ;它的示例暗示测试的数量等于从 dataProvider 方法返回的数据项的数量。

看来 dataProvider 的调用本身已被计为测试用例。

Answer 1

Cest 类的所有公共(public)方法都作为测试执行，
避免使 MyDataProvider 受到保护或将其重命名为 _MyDataProvider
如记录在 https://codeception.com/docs/07-AdvancedUsage#DataProvider-Annotations
