iOS - 运行Swift的单元测试时找不到“MyProject-Swift.h”文件 [英] iOS - 'MyProject-Swift.h' file not found when running Unit Tests for Swift

问题描述

我正在为我的项目设置单元测试。
这是一个现有的Objective-C应用程序，我最近添加了一个Swift类。我已经设置了'MyProject-Swift.h'和Swift Bridging文件（'MyProject'和'MyProjectTest'），并且我可以使用Objective-C和Swift代码很好地构建和运行应用程序。

然而，现在我想在新的Swift类上运行一些单元测试。
我设置了我的测试文件，它看起来像下面这样：

MySwiftClassTests.swift：

  import UIKit 
 import XCTest 
 import MyProject 
 
 class MySwiftClassTests：XCTestCase {
 
覆盖func setUp（）{
 super.setUp（）
 //将设置代码放在这里。在调用该类中的每个测试方法之前调用此方法。 
} 
 
覆盖func tearDown（）{
 //将拆卸代码放在这里。调用该类中的每个测试方法后调用此方法。 
 super.tearDown（）
} 
 
 func testExample（）{
 //这是一个功能测试用例的例子。 
 XCTAssert（true，Pass）
} 
 
 func testPerformanceExample（）{
 //这是性能测试用例的一个例子。 
 self.measureBlock（）{
 //把你想要测量的代码放在这里。 
 
 
 
 $ b  

我得到运行应用程序时出现此错误：

 'MyProject-Swift.h'文件未找到
  

我不确定为什么只有在尝试运行测试时才会出现这种情况。
有何建议？

解决方案

MyProject-Swift.h以下路径：

$（TARGET_TEMP_DIR）/../$（PROJECT_NAME）.build / DerivedSources

我最终将这个添加到我的单元测试目标的Header搜索路径中。

同样@hyouuu指出关于成为已知问题，希望苹果能够在他们的最后提供一些很好的解决方案。直到我相信我们需要使用这个上面的解决方案。

I am trying to setup Unit Testing for my project. It is an existing Objective-C app, that I have recently added one Swift class to. I have setup the 'MyProject-Swift.h' and Swift Bridging files (both 'MyProject' and 'MyProjectTest') and I am able to build and run the app just fine using both Objective-C and Swift code.

However, now I want to run some Unit Tests on the new Swift class. I setup my test file and it looks like the following:

MySwiftClassTests.swift:

import UIKit
import XCTest
import MyProject

class MySwiftClassTests: XCTestCase {

    override func setUp() {
        super.setUp()
        // Put setup code here. This method is called before the invocation of each test method in the class.
    }

    override func tearDown() {
        // Put teardown code here. This method is called after the invocation of each test method in the class.
        super.tearDown()
    }

    func testExample() {
        // This is an example of a functional test case.
        XCTAssert(true, "Pass")
    }

    func testPerformanceExample() {
        // This is an example of a performance test case.
        self.measureBlock() {
            // Put the code you want to measure the time of here.
        }
    }

}

I get this error when running the app as Test:

'MyProject-Swift.h' file not found

I am not sure why this happens only when trying to run the Tests. Any suggestions?

解决方案

"MyProject-Swift.h" file is generated at following path:

"$(TARGET_TEMP_DIR)/../$(PROJECT_NAME).build/DerivedSources"

I end up adding this to Header Search Paths for my Unit Test target.

Also as @hyouuu pointed out about being the known issue, hopefully Apple will provide some good solution at their end. Until I believe we need to use this above solution.
