java.lang.IllegalStateException: Missing the '-javaagent' JVM argument. Make sure you run the tests with the Quasar java agent attached to your JVM
问题
当尝试运行CORDA的测试用例时，给定的测试用例出现以下错误。我使用的是JDK 1.8，在Windows 10上使用Intellij IDEA。尽管我已经在VM选项中提到了Quasar.jar。
RUN >> 编辑配置 >> Junit >> 所需的测试类 >> VM选项：-ea -javaagent:lib\quasar.jar

@Before

network.runNetwork();
}

@Test
public void transactionHasNoInputsHasOneMetalStateOutputWithTheCorrectOwner() throws Exception {

CordaFuture<SignedTransaction> future = Mint.startFlow(flow);
setup();
SignedTransaction signedTransaction = future.get();
assertEquals (0, signedTransaction.getTx().getInputs().size());

MetalState output = signedTransaction.getTx().outputsOfType(MetalState.class).get(0);
assertEquals(A.getInfo().getLegalIdentities().get(0), output.getOwner());
}
}
错误信息如下：
java.lang.IllegalStateException: Missing the '-javaagent' JVM argument. Make sure you run the tests with the Quasar java agent attached to your JVM.
See https://docs.corda.net/head/testing.html#running-tests-in-intellij - 'Fiber classes not instrumented' for more details.

我建议使用Gradle测试运行程序，这样您就不必手动设置javaagent标志。
要使用Gradle测试运行程序，请点击运行/调试配置下拉菜单 > 编辑配置... > + > Gradle 在出现的表单中，填写详细信息：
Gradle项目：[您的项目路径]
任务：:cleanTest :test
参数：--tests "<测试类路径>"
参考如下：
英文:
I would recommend using the Gradle Test Runner so that you don't have to set the javaagent flag manually.
To use Gradle Test Runner Click the Run/Debug configuration drop down > Edit Configurations... > + > Gradle In the form that appears, fill in the details:
Gradle-Project : [path to your project]
Task: :cleanTest :test
Arguments: --tests "<TestClass Path>"
