Question

我在Swift中编写单元测试。

我调用我的app方法并通过// Call to hashCode() to print the author that will be removed Calling hashcode: 400605768 // Author that will be removed >removeAuthor [400605768]: Author{id=self, name=Self Centre, forename=null, familyName=null, role=Writer} // List before calling remove, it gives 2 authors [2] Authors BEFORE: Calling hashcode: -1820871746 [-1820871746] Author{id=self, name=Self Centre, forename=null, familyName=null, role=Researcher} Calling hashcode: 400605768 [400605768] Author{id=self, name=Self Centre, forename=null, familyName=null, role=Writer} // This hashCode call is probably done by remove(). As it can be seen, the object to be removed *is* on the Set Calling hashcode: 400605768 // List after calling remove, it gives again 2 authors [2] Authors AFTER: Calling hashcode: -1820871746 [-1820871746] Author{id=self, name=Self Centre, forename=null, familyName=null, role=Researcher} Calling hashcode: 400605768 [400605768] Author{id=self, name=Self Centre, forename=null, familyName=null, role=Writer} Calling hashcode: -1820871746获取代表请求的JSON对象。

现在我要验证JSON的所有字段。每个验证都应该在单独的测试中。

这就是我写的：

delegate

问题是：每次运行class LaunchTests: XCTestCase, TestServerHandlerDelegate { var theExpectation:XCTestExpectation? var launchRequest:String? = nil public func onSend(_ data: Data!) { launchRequest = NSString(data: data, encoding: String.Encoding.utf8.rawValue) theExpectation?.fulfill() } override func setUp() { super.setUp() // we wait in setUp till get 'launchRequest' if launchRequest == nil { theExpectation = expectation(description: "initialized") MyApp.shared().setDelegate(self) MyApp.shared().launch() // Loop until the expectation is fulfilled in onDone method waitForExpectations(timeout: 500, handler: { error in XCTAssertNil(error, "Oh, we got timeout")}) } } override func tearDown() { super.tearDown() } func test___01_platform(){ if let _ = fetchJsonValue(key: "somekey", value: launchRequest){ //... } } func test___02_platform(){ if let _ = fetchJsonValue(key: "platform", value: launchRequest){ //... } }都是launchRequest。我知道它的行为是正确的，但我只想调用nil一次并对MyApp.shared().launch()数据运行多次测试。

我怎样才能实现它？

（我知道它不是单元测试的好习惯，但无论如何）

谢谢，

Answer 1

好吧，如果你真的想要，你可以把launchRequest放在你的LaunchTests课程之外：

var launchRequest:String? = nil

class LaunchTests: XCTestCase, TestServerHandlerDelegate {
  ...
}

Answer 2

解决方案是将MANAGE_DOCUMENTS定义为launchRequest（正如Maxim Shoustin所提到的）：

static

在这种情况下，一切都按预期工作

如何定义不改变类下所有测试的全局最终变量？
