DisableOnDebug (JUnit API 文档)

java.lang.Object
- org.junit.rules.DisableOnDebug

所有已实现的接口:
TestRule
```
public class DisableOnDebug
extends Object
implements TestRule
```
The DisableOnDebug Rule allows you to label certain rules to be disabled when debugging.
The most illustrative use case is for tests that make use of the Timeout rule, when ran in debug mode the test may terminate on timeout abruptly during debugging. Developers may disable the timeout, or increase the timeout by making a code change on tests that need debugging and remember revert the change afterwards or rules such as Timeout that may be disabled during debugging may be wrapped in a DisableOnDebug.
The important benefit of this feature is that you can disable such rules without any making any modifications to your test class to remove them during debugging.
This does nothing to tackle timeouts or time sensitive code under test when debugging and may make this less useful in such circumstances.
Example usage:
```
 public static class DisableTimeoutOnDebugSampleTest {
 
     @Rule
     public TestRule timeout = new DisableOnDebug(new Timeout(20));
 
     @Test
     public void myTest() {
         int i = 0;
         assertEquals(0, i); // suppose you had a break point here to inspect i
     }
 }
 
```

public DisableOnDebug(TestRule rule)
```
    Create a DisableOnDebug instance with the timeout specified in milliseconds.
    参数:
    rule - to disable during debugging

  - apply
```
public Statement apply(Statement base,
                       Description description)
```
    从接口复制的说明: TestRule
    Modifies the method-running Statement to implement this test-running rule.
    指定者:
    apply 在接口中 TestRule
    参数:
    base - The Statement to be modified
    description - A Description of the test implemented in base
    返回:
    a new statement, which may be the same as base, a wrapper around base, or a completely new Statement.
    另请参阅:
    TestRule.apply(Statement, Description)
  - isDebugging
```
public boolean isDebugging()
```
    Returns true if the JVM is in debug mode. This method may be used by test classes to take additional action to disable code paths that interfere with debugging if required.
    返回:
    true if the current JVM is in debug mode, false otherwise
