如何在不模拟doclet的情况下测试？

Question

我使用Java 9+编写了一个Doclet。我想使用JUnit框架来测试它，而不是模拟Doclet。有什么好办法吗？

当你知道该使用什么时，答案很简单。下面是一个手动调用的示例，可以在JUnit测试中使用。

DocumentationTool systemDocumentationTool = ToolProvider.getSystemDocumentationTool();
        String[] args = new String[] {
          "-sourcepath",
          "./src/test/java",
          "-subpackages",
          "<whatever-package-in-test-sources>",
          "<whatever-package-in-test-sources>",
          "-d",
          "whatever not used just to show compatibility",
          "-author",
          "whatever not used just to show compatibility",
          "-doctitle",
          "whatever not used just to show compatibility",
          "-windowtitle",
          "whatever not used just to show compatibility",
          "-classdir",
          BUILD_PROPERTY_FILE_LOCATION
        };
        DocumentationTool.DocumentationTask task = systemDocumentationTool.getTask(null, null, null,
          <MyDocletClass>.class, Arrays.asList(args), null);

        task.call();
        // Your checks after invocation
