Hello,
I'm trying to write a unit test for my patch at https://issues.apache.org/jira/browse/HADOOP-7943 and I have a few questions based on reading the wiki (http://wiki.apache.org/hadoop/HowToDevelopUnitTests) 1. The patch is for v1.0, not trunk. Should I be using the "junit.framework" style tests or the "org.junit" stuff? (I think this might correspond to JUnit v3 vs. v4? It seems like trunk has switched to this new style, but not 1.0) 2. The wiki says "Avoid starting servers (including Jetty and Mini{DFS|MR}Clusters) in unit tests... Try to use one of the lighter weight test doubles." How do I do this? I want to test copying a file from HDFS to a local file system; is it possible to run this test without starting a mini cluster? 3. Are there any existing tests of the FsShell that I could piggy back off of? I see trunk has some tests relating to the shell, but none testing full-out functionality like copying a file. Also, adding the answers to #1 and #2 to the wiki would be helpful. Thanks! -Ben
