Question

我有一个长的JSON文件（约10000行），我想将其用于测试目的（而不是每次都访问外部服务器：<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <corners android:radius="@dimen/_20sdp" /> <gradient android:startColor="@color/ThemeColor" android:endColor="@color/ThemeColor" android:centerColor="@color/ThemeColor"/> </shape>

在控制器中替代httparty帖子的正确语法是什么

response_test.json

带有对文件的引用？该文件应该存储在哪里？

Answer 1

extension EditLocalPhotosCollectionCell: UICollectionViewDelegate, UICollectionViewDataSource {

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return imagesPicked.count
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    photoCell = collectionView.dequeueReusableCell(withReuseIdentifier: "photoCellID", for: indexPath) as! EditLocalPhotoCell
    photoCell.backgroundColor = currentTheme.backgroundColor
    photoCell.photoView.image = imagesPicked[indexPath.row]

    photoCell.photoView.layer.masksToBounds = false
    photoCell.photoView.layer.cornerRadius = photoCell.photoView.frame.width / 16
    photoCell.photoView.clipsToBounds = true

    let width: CGFloat = 20

    deleteButton.setImage(#imageLiteral(resourceName: "close"), for: .normal)
    deleteButton.frame = CGRect(x: photoCell.photoView.frame.width - width / 2, y: 0, width: width, height: width)
    deleteButton.addTarget(self, action: #selector(deletePhoto), for: .touchUpInside)
    photoCell.addSubview(deleteButton)

    let longPressure = UILongPressGestureRecognizer(target: self, action: #selector(deletePhoto))
    photoCell.isUserInteractionEnabled = true
    photoCell.addGestureRecognizer(longPressure)

    return photoCell
}

@objc func deletePhoto() {
    isEditingModeActive = true
}

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
    return CGSize(width: 70, height: 70)
}

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

    if indexPath.row == (CreateLocalTVC.imagesPicked.index(of: #imageLiteral(resourceName: "addPhotos"))) {
        NotificationCenter.default.post(name: NSNotification.Name(rawValue: "ADD_PHOTOS_SELECTED"), object: nil)
    }

    if isEditingModeActive && indexPath.row != (CreateLocalTVC.imagesPicked.index(of: #imageLiteral(resourceName: "addPhotos"))) {

        print("REMOVED ITEM AT: \(indexPath)")

        collectionView.deleteItems(at: [IndexPath(item: indexPath.row, section: 0)])
        imagesPicked.remove(at: indexPath.row)
        collectionView.reloadData()
    }
}
}

JSON模拟文件最好存储在fixtures目录中。如果您使用的是RSpec，则可以将文件存储在spec/fixtures/mocks中。

更新：

如果要在测试环境中模拟API调用，请按以下步骤操作：

安装webmock gem
添加以下内容以在spec/spec_helper中配置webmock以禁用所有外部API调用。 Webmock将引发错误并建议如何对相应的API调用进行存根。
```
# spec/spec_helper.rb

require 'webmock/rspec'
WebMock.disable_net_connect!(allow_localhost: true)
```

然后，在测试中进行API调用之前，先将请求返回response_test.json作为正文

stub_request(:post, 'https://test.com/search')
  .to_return(headers: { 'Content-Type': 'application/vnd.api+json; charset=utf-8' },
             body: response_test.json)

result = HTTParty.post(
  'https://test.com/search',
  :body => [...]

# Assert that result matches some value in the JSON content      
expect(result.some_attribute).to eq(some_value)

要进行一些清理，您还可以将stub_request块提取到方法中，并在API调用之前调用该方法。
