hasJUnitAnnotation
public static boolean hasJUnitAnnotation (Class<?> classObj)
检查类是否看起来像 JUnit 测试。
| 参数 |
|---|
classObj |
Class：要检查是否存在注释的类 |
| 返回 |
|---|
boolean |
类对象是否具有 JUnit4 测试注解 |
testLoadClass
public static boolean testLoadClass (String className,
URLClassLoader cl,
String jarName)
测试类是否为合适的测试类。
在本例中，“合适”是指该类是使用某个标准运行器或其子类的有效 JUnit 测试类。显然，类也应加载。
| 返回 |
|---|
boolean |
如果我们应将此类视为测试类，则为 true；否则为 false |
