Question

我正在使用MacOS，并且在.bash_profile文件中定义了一些环境变量。我正在IntelliJ IDEA中运行Scalatest框架，并且定义了测试类文件：

class ApiCheckerTest extends FunSuite {
    val userid: String = sys.env(Constants.KEY_CLOUD_USERNAME)   //Value of parameter is CLOUD_USERNAME
    val password: String = sys.env(Constants.KEY_CLOUD_PASSWORD)
    val url: String = sys.env(Constants.KEY_CLOUD_DB2_URL)

    test("ApiChecker.getAuthToken.noUserPasswordUrl") {
        val apiChecker = new ApiChecker()
        assert(apiChecker.getAuthToken("", "", "").isEmpty)
    }

    //... <Other test cases>
}

运行此Test类文件时，出现如下错误：

An exception or error caused a run to abort: key not found: CLOUD_USERNAME 
java.util.NoSuchElementException: key not found: CLOUD_USERNAME

现在，当我打开scala终端并在其中运行sys.env()时，会得到输出：

scala> sys.env("CLOUD_USERNAME")
res0: String = sparker0i

如果这可以在Scala终端中使用，为什么在IntelliJ的Test类中不起作用？

打开IntelliJ IDEA之后，我创建了这些环境变量。重新启动IDE解决了问题

找不到系统环境变量
