DeviceJUnit4ClassRunner.TestLogData

public static class DeviceJUnit4ClassRunner.TestLogData
extends ExternalResource

Implementation of ExternalResource and TestRule. This rule allows to log logs during a test case (inside @Test). It guarantees that the log list is cleaned between tests, so the same rule object can be re-used.

Example:
 @Rule
 public TestLogData logs = new TestLogData();

 @Test
 public void testFoo() {
     logs.addTestLog("logcat", LogDataType.LOGCAT, new FileInputStreamSource(logcatFile));
 }

 @Test
 public void testFoo2() {
     logs.addTestLog("logcat2", LogDataType.LOGCAT, new FileInputStreamSource(logcatFile2));
 }
