我如何在Codeception中测试这一行

Question

我正在编写一些单元测试，并努力在Yii2中捕获这个小模型的剩余1行。

UserSearch.php

public function search($params)
{
    $query = User::find();

    // add conditions that should always apply here

    $dataProvider = new ActiveDataProvider([
        'query' => $query,
    ]);

    $this->load($params);

    if (!$this->validate()) {
        // $query->where('0=1');
        return $dataProvider; // This line in tests is red and marked as not executed
    }

    // grid filtering conditions
    $query->andFilterWhere([
        'id' => $this->id,
        'date_added' => $this->date_added,
        'last_login' => $this->last_login,
    ]);

    $query->andFilterWhere(['like', 'username', $this->username])

    return $dataProvider;
}

UserTest.php

public function testUserSearch()
{
    $model = new UserSearch();
    expect_that($model->search(['id' => 2]));
}

public function testInvalidDataProvider()
{
    $model = new UserSearch();
    expect_that($model->search(['id' => '2']));
}

第二个测试正确传递，!this->Validate()方法失败，因为id不是整数，为什么返回语句不反映为在代码覆盖中执行。我在这里误解了什么？

Answer 1

• 整数必须仅包含数字[请参阅验证]：https://github.com/yiisoft/yii2/blob/master/framework/validators/NumberValidator.php#L51＆＃39; 2＆＃39;是有效整数
• model-＆gt; search（）返回ActiveDataProvider。是对的。
