在CodeCeption中，测试计数比数据提供程序的数据计数更多。

Question

我有一个Cest in CodeCeption，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;
    }
}

正如您所看到的，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：

OK (4 tests, 0 assertions)

我回顾了PHPUnit DataProvider文档；它的示例意味着测试的数量等于从dataProvider方法返回的数据项的数量。

看来dataProvider的调用本身已经被算作一个测试用例了。

Answer 1

Cest类的所有公共方法都作为测试执行，

若要避免这种情况，请将MyDataProvider保护或将其重命名为_MyDataProvider

正如https://codeception.com/docs/07-AdvancedUsage#DataProvider-Annotations记录的那样
