Use the copy command to restore a deleted file: $ svn copy http://svn.example.com/path/to/svn/repo... @revision must be a revision number before the file was deleted. You can use the info command to view the info before restoring: $ svn info http://svn.example.com/path/to/svn/repo...

The command " svn info " prints information about the current directory: $ svn info Path: . URL: http://svn.example.c... where: Revision: is the last syncup (update) revision of the current TARGET (artifact/file/directory, whatever you call). This number bumps up to that of the current project revision number after you do an update. Last Changed Rev: is the revision number of the latest change for the current TARGET . If TARGET is a directory, it is the revision number of the latest change within the directory, including all subdirectories. However , this number is not accurate after you do a check in without a following update. The revision number for the file or directory you checked in will have higher revision number than its parent/ancestor. To...

The Android unit test framework is based on JUnit 3 , not JUnit 4. Test cases have to extend junit.framework.TestCase or a subclass (such as android.test.InstrumentationTestCase ). Tests are identified by public methods whose name starts with test , not methods annotated with @Test (as in JUnit 4). An Android test suite is packaged as an APK, just like the application being tested. To create a test package, first you need to identify the application package it is testing. Google suggests to put the test package source in a directory named tests/ alongside the src/ directory of the main application. At runtime, Android instrumentation loads both the test package and the application under test into the same process. Therefore, the tests can invoke methods on...
