在Swift中将测试添加到OSX项目时，无法访问主目标方法 [英] Unable to access Main Target Methods when Adding Tests to OSX Project in Swift

问题描述

我已经尝试添加一个测试包到我的项目，似乎已经成功。

但是，当我尝试在我的主项目中创建类的实例时，我无法看到它们。

项目似乎构建得很好，但我可以实例化任何测试对象

  class EmailHelper： NSObject {
 func generateEmailBody（greeting：String，bodyContent：String） - > String {
 //内容在这里
返回消息
} 
} 
 
 import XCTest 
 
类MyProject_DesktopTests：XCTestCase {
 
 override func setUp（）{
 super.setUp（）
 //将设置代码放在这里。在调用类中的每个测试方法之前调用此方法。 
} 
 
 override func tearDown（）{
 //在这里放置teardown代码。此方法在调用类中的每个测试方法后调用。 
 super.tearDown（）
} 
 
 func testExample（）{
 //测试会进入这里，但我似乎无法解析EmailHelper class-它生成一个lint错误
 //这是一个功能测试用例的示例。 
 //使用XCTAssert和相关函数来验证测试是否产生正确的结果。 
} 
 
 func testPerformanceExample（）{
 //这是一个性能测试用例的例子。 
 self.measureBlock {
 //输入您要测量此处的时间的代码。 
} 
} 
 
} 
  

方案

我设法通过添加Testable到类的顶部（这似乎是OSX的具体问题）工作。

  import XCTest 
 @testable import MyProjectName //< ---这是缺少的位.... :) 
 class MyProject_DesktopTests：XCTestCase {
 
 override func setUp（）{
 super.setUp（）
 //在这里放置setup代码。在调用类中的每个测试方法之前调用此方法。 
} 
 
 override func tearDown（）{
 //在这里放置teardown代码。此方法在调用类中的每个测试方法后调用。 
 super.tearDown（）
} 
 
 func testExample（）{
 //测试会进入这里，但我似乎无法解析EmailHelper class-它生成一个lint错误
 //这是一个功能测试用例的示例。 
 //使用XCTAssert和相关函数来验证测试是否产生正确的结果。 
} 
 
 func testPerformanceExample（）{
 //这是一个性能测试用例的例子。 
 self.measureBlock {
 //输入您要测量此处的时间的代码。 
} 
} 
 
} 
  

一定要清理你的项目添加它后，它似乎工作。

I have tried adding a testing bundle to my Project which seems to have succeeded.

However when I try to create instances of the Classes in my main project- I am unable to see them.

The Project seems to build fine - but I can' instantiate any of the test objects

Any ideas how to access them

Example Class to Test:

class EmailHelper: NSObject {
    func generateEmailBody (greeting: String, bodyContent: String) -> String {
        //Content goes in here
return message
    }
}

import XCTest

class MyProject_DesktopTests: 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() {
    // The Test would go in here but I can't seem to resolve EmailHelper class- it generates a lint error
        // This is an example of a functional test case.
        // Use XCTAssert and related functions to verify your tests produce the correct results.
    }

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

}

解决方案

I managed to get it working by adding Testable to the top of the class( This appears to be OSX specific issue)

import XCTest
@testable import MyProjectName // <--- This was the missing bit.... :)
class MyProject_DesktopTests: 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() {
    // The Test would go in here but I can't seem to resolve EmailHelper class- it generates a lint error
        // This is an example of a functional test case.
        // Use XCTAssert and related functions to verify your tests produce the correct results.
    }

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

}

Also be sure to clean your project after adding it an it seems to work.
