I'm running Fedora 18. No, my file-system is not read-only -- this is the file-system of my developer workstation, the one I work on (so can't be readonly). To get past the earlier, NonWritableChannelException exception that I was getting, I modified the H2 code as follows... TestFileSystem.testSimple(String) { ... // new AssertThrows(IOException.class) { new AssertThrows(NonWritableChannelException.class) { new AssertThrows(java.nio.channels.NonWritableChannelException.class) { @Override public void test() throws Exception { fc.truncate(10); } }; ... and it was happy. But then I started getting this NPE: java.lang.NullPointerException at org.h2.test.unit.TestFileSystem.testClasspath(TestFileSystem.java:220) at org.h2.test.unit.TestFileSystem.test(TestFileSystem.java:73) at org.h2.test.unit.TestFileSystem.main(TestFileSystem.java:55) at com.amritatech.rephrase.H2DatabaseTest.main(H2DatabaseTest.java:40) which is the following code: private void testClasspath() throws IOException { String resource = "org/h2/test/testSimple.in.txt"; InputStream in; in = getClass().getResourceAsStream("/" + resource); assertTrue(in != null); in.close(); in = getClass().getClassLoader().getResourceAsStream(resource); // line 220 I'm using version 1.3.174 codebase, btw. Is this unit testing exercise supposed to be run from some specialized test-jar bundle of H2? Fyi, I'm imported the codebase in Eclipse and I'm running it from there, so I'm not aware of any specialized path/classpath setups that may be required. > Before you think about using your file system with a database, I suggest > to ensure the unit test (TestFileSystem) passes. > Yes, I definitely intend to do that. But another basic question that I have is this: Once the TestFileSystem unit test begins to pass on the default ("file:/") file-system, and once I have register()'ed my file-system using my FilePath-subclass's register(), do I need to do anything else? For example, do I need to... a) comment out calls to file-systems (like zip/zip2, cache/cache2, ...) that seem 'irrelevant' to testing my own file-system? b) change TestBase.BASE_TEST_DIR and .TEMP_DIR to point to my file-system, like so... BASE_TEST_DIR = "myfs:/path/to/data" TEMP_DIR = "myfs:/path/to/data/tmp" ... early on in the control flow?
