LaravelのユニットテストでDBにないエラーを明確にする

すみませんが、日本語訳はあとにします。

Problem

When seeInDatabase asserting was failed, I can’t not known where the path of properies is not match.

Example: With bellow test, I will receive the bellow message.

Test code:

    $this->seeInDatabase('les_knowledge', [
        'lesson_id' => $lesson->id,
        'number' => 1,
        'content_en' => '~ years old DIFFFFFFFFFF',
        'explanation_en' => 'In Japan, you are born as a 0 year-old and turn 1 on your first birthday.',
    ]);

Test result:

Unable to find row in database table [les_knowledge] that matched attributes
javascript
[{
"lesson_id":98,"number":1,
"content_en":"~ years old DIFFFFFFFFFF",
"explanation_en":"In Japan, you are born as a 0 year-old and turn 1 on your first birthday."
}]


It is hard to find where is the path don’t match.

Solution

Create a function likes a bellow.

    function seeInDatabaseAndHasProperties($table, array $filter, array $properties, $connection = null){
        $this->seeInDatabase($table, $filter, $connection);
        $model = (array)DB::table($table)->where($filter)->first();
        $this->assertEquals($properties, Arr::only($model, array_keys($properties)));
    }

Test code will be:

    $this->seeInDatabaseAndHasProperties('les_knowledge',
    [
        'lesson_id' => $lesson->id,
        'number' => 1,
    ], [
        'content_en' => '~ years old DIFFFFFFFFFF',
        'explanation_en' => 'In Japan, you are born as a 0 year-old and turn 1 on your first birthday.',
    ]);

Test result will be:

Failed asserting that two arrays are equal.
--- Expected
+++ Actual
@@ @@
Array (
    -    'content_en' => '~ years old DIFFFFFFFFFF'
    +    'content_en' => '~ years old'
    'explanation_en' => 'In Japan, you are born as a 0...thday.'
)

Now you can easily see which properties don’t match.
