GWT JUnit：com.google.gwt.dev.jjs.InternalCompilerException：访问期间出现意外错误

时间：2011-05-06 14:00:38

标签： java gwt netbeans-6.9 junit4

随着我的应用程序扩展，我决定应用JUnit测试，因此我可以阻止NullPointerException 尽可能多地特别是在Activity＆amp;放置以及RequestFactory。

但是，我试图在ClientFactory上执行测试，我已经能够将参数传递给JUnit，就像 followijng：

gwt.test.jvmargs = -Xmx256M -Dgwt.args =“ - testBeginTimeout 5”-Dgwt.args =“ - prod”-Dgwt.args =“ - runStyle Manual：1”

当我运行测试时，我收到InternalCompilerException。下面是错误堆栈：

GWT命令行工具公开的测试工具与JUnit不兼容，导致错误：

  

Caused by: java.lang.SecurityException: Prohibited package name: java.io

您有两种选择：

  1. 如果您正在测试的单元没有调用GWT.create()（隐式或显式）或以其他方式依赖本机Javascript，您可以像使用任何其他项目一样使用JUnit（即从命令行） ：java java org.junit.runner.JUnitCore ... Here is some more info on JUnit testing in GWT。

  2. 如果您正在测试的单元以某种方式依赖于原生Javascript，则需要使用GWTTestCase described in the GWT documentation。

    3. 考虑查看MVP Pattern，因为其明确的目标之一是使用JUnit尽可能多地测试应用程序（主要是因为它比基于{的测试更快 {1}}）。
