XCUITests - 通过命令行传入环境变量

Question

我正在尝试通过命令行向我的 XCUI测试传递一个值。我知道可以通过以下方式为 XCTest（非 UI）执行此操作：

xcodebuild -verbose test -workspace MyWorkspace.xcworkspace -derivedDataPath derivedData -scheme "MyScheme" -configuration Debug SYMROOT="$(pwd)"/build -destination platform="iOS Simulator",name="iPad Air",OS=10.2 -only-testing:UITests/UITests -resultBundlePath logfiles MY_SETTING="setting_value" MY_OTHER_SETTING="setting_value_2"

然而，这在我的 XCUI 测试中似乎不起作用，因为代码没有进入 #ifdef MY_SETTING 块。还有另一种方法可以通过命令行将值传递给我的 XCUITest 吗？

Answer 1

没有通过 xcodebuild 将值传递给 UI 测试的本机方法。在运行ning UI 测试之前，您可以使用 perl 单行代码替换项目中的值：

perl -pi -e 's/valueToReplace/replacementValue/g' <path to file to modify>

我过去曾使用此方法替换项目中的基础 URL，以便运行 UI 针对模拟服务器进行测试。

Answer 2

这是可以做到的，是的，不过你少了两个步骤。

设置您的 Scheme，使环境变量的值设置为 MY_SETTING。
if let mySetting = ProcessInfo.processInfo.environment['MY_SETTING'] { // do whatever you want because it is defined }

有点像 Accessing user defined variables passed in from xcodebuild command line

感谢您在下面的回答，我发现这个答案最终对我有用。 Applitools 的大神帮我解决了这个问题，详细步骤如下：

The most important step is to make Xcode know about the variables we are going to pass from command line.

Lets call our variable TEST_VAR. To do this follow these steps please:

1) Open to Xcode, select TEST TARGET(not target of application) https://www.evernote.com/l/AR0BF8Te8_hFGYON8jKqIkv3grnwFky16tc

2) Select “Build Settings” and add in the “Preprocessor Macros” section TEST_VAR=$(TEST_VAR)

https://www.evernote.com/l/AR1b4QRysBlDRro3sbKH1hSy6s_2s_Qkxnw

3) Add new user-define setting by tapping “+” button and selecting “Add User-Defined Setting” https://www.evernote.com/l/AR0qflFqN2lIEoKVVzUUYRArM49Qb1d2TUE

4) Set a default value for your new custom setting https://www.evernote.com/l/AR32JBfPDhFIN76ZlJjq1eV7v8bry9WImfE

Now variable TEST_VAR is ready to use.

This is an example how I pass it to the test. My test project is inside a workspace. So I open Terminal and go to the destination folder of my workspace.

xcodebuild -workspace workspace_name\ workspace.xcworkspace/ -scheme YourSchemeName -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 6,OS=10.2' -only-testing:TestTargetName/TestCaseName/testName TEST_VAR=1988 test

Inside the test I can get the value of TEST_VAR variable somehow like this: NSLog(@"TEST_VAR %li", (long)TEST_VAR);

但是，我还需要定义另一个预处理器宏来解包我传入的值的字符串值，如下所述：Accessing the value of a Preprocessor Macro definition.

所以为了检索字符串值，我做了类似的事情：

NSLog(@"TEST_VAR %s", MACRO_VALUE(TEST_VAR))

如果您需要将环境变量从您的架构传递到 XCUITes，请修改 XCTestCase -> app.launchEnvironment 对象，在此的每个测试 class方式：

Swift 3

override func setUp(){
    app.launchEnvironment = ProcessInfo.processInfo.environment
}
