我正在使用 MacOS，并且在.bash_profile文件中定义了一些环境变量。我在 IntelliJ IDEA 中运行 Scalatest 框架，并且我已经定义了我的测试类文件：

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>
}

当我运行这个测试类文件时，我收到如下所示的错误：

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 终端并在那里运行sys.env()时，我得到一个输出：

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

如果这可以在 Scala 终端中工作，为什么这在 IntelliJ 的 Test 类中不起作用？

我在打开 IntelliJ IDEA 后创建了这些环境变量。重新启动 IDE 解决了问题
