数据提供者在phpunit中发布

Question

This is my data provider function:

public function addDataProvider() {
    return [
        [
            [
                'currency' => 'eur',
                'amount' => 800,
            ],
            [
                'currency' => '12312k',
                'amount' => 1201,
            ],
            [
                'currency' => 'DKK',
                'amount' => 1200.01
            ],
            [
                'currency' => 'SEK  ',
                'amount' => 1200.01
            ]
        ],
    ];
}

This is my test function:

/**
 * Test case
 * @covers AmountPerCustomer::checkAmounts()
 * @dataProvider addDataProvider
 */
public function testCheckAmountUsingCurrency($query)
{
        ....
        try {
            $ordersPerCustomer->checkAmounts($query['amount'], $query['currency'], $dateInterval);
            $this->fail("Expected Exception has not been raised.");
        }catch (\Exception $error) {
            $this->assertEquals($error->getMessage(), "Total order amount event given parameters exceed sum {$query['amount']} since {$dateInterval->format('H:i d-m-Y')} from source {$source}");
        }
}

I am getting this success mesage: OK (1 test, 1 assertion) , My question why I have only one assertion. I have multiple array values in my provider . What am I doing wrong ?

Thank you!

As @localheinz suggested in the comments, it is a depth of array issue. This is how my array should look like:

public function addDataProvider() {
    return [
        [
            [
                'currency' => 'eur',
                'amount' => 800,
            ]
        ],
        [
            [
                'currency' => 'dkk',
                'amount' => 1201,
            ],
        ],
        [
            [
                'currency' => 'GBP',
                'amount' => 1201,
            ],
        ],
        [
            [
                'currency' => 'sek',
                'amount' => 1200.01,
            ],
        ],
    ];
}
