Steve Loughran commented on HADOOP-5732:
----------------------------------------
Basic Junit is fairly simple: extend TestCase and write a testXXX method for
every test you want.
Functional testing of sftp will be tricker as it should only work if the test
runner has been told to do so,
Have a look at org.apache.hadoop.fs.TestLocalFileSystem to see a filesystem
test, and
org.apache.hadoop.fs.TestLocalFileSystemPermission to see one that uses
System.getProperty() to look for specific properties beginning with test. to
control its operation -and which skips any attempts to work on windows
for SFTP, a good test would be to take a filesystem URL as a system property
(e.g. test.sftp.url) and then have a series of tests that test out the various
filesystem methods, starting with the basic ones (Write that test first, get it
working before doing the others)
testConnect: try to connect to that URL, close it
testCreateFile: connect, create a file, delete it ,close the filesystem
testFileExists: as above, check the file exists
testReadFile: connect, create a file, write to it, close the file, read it in,
checksum the data, delete it and close the FS
testRenameFile: create, rename a file
testStatFile: test getFileStatus
Although you can do all of this in one sequence, breaking it up is better for
debugging problems -when you see an error report, you can often guess what the
problem is
And some trick ones
testDeleteNonexistentFile -delete a file that isn't there
testRenameNonexistentFile
testRenameOntoExistingFile
testConcurrentAccess: try to open the same file for writing twice, see what
happens
...etc.
Thinking up tests that break the system are the most fun, and the way to
reliable code.
