我將如何測試代碼中的這一行

Question

我正在編寫一些單元測試，並努力在Yii2中捕獲這個小模型的剩餘一行。

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'])); 
} 

第二測試通過正確地爲作爲ID不是整數!this->Validate()方法失敗，爲什麼不返回語句反映爲在代碼覆蓋範圍內執行。我在這裏誤解了什麼？

Answer 1

• 整數只能包含數字[見驗證]：https://github.com/yiisoft/yii2/blob/master/framework/validators/NumberValidator.php#L51 '2' 是有效的整數
• 模型 - >搜索（）的返回ActiveDataProvider。是正確的。
