Dale LaBossiere commented on EDGENT-306:
----------------------------------------
On vacation right now (I know, sad that I'm responding to this :-) but ...
I haven't looked at the code you attached but I'll note there's at least one
existing test for this:
FileStreamsTextFileWriterTest.testWriterWatcherReader().
There's also a sample that works. See java8/scripts/connectors/file/README.
Also read the FileStreams.directoryWatcher javadoc for caveats about MacOS
(maybe others?).
Do those things add any clarity?
> With edgent Tester, failed to read file content from the newly appeared files

> Key: EDGENT-306
> URL: https://issues.apache.org/jira/browse/EDGENT-306
> Project: Edgent
> Issue Type: Bug
> Components: Test
> Affects Versions: 0.4.0
> Reporter: Rui Shen
> Attachments: CopyOfFileStreamsTest.java, FileReaderApp.java, M2.png
>
>
> I got a trouble when using edgent Tester. The scenario that I am trying to
> test is:
> 1) There is a empty directory (e.g "testdata")
> 2) Use FileStreams.directoryWatcher to watch the directory "testdata" and use
> FileStreams.textFileReader to read content of newly appeared files in the
> directory.
>
> I am trying to use edgent Tester to write a unit test of this scenario (I
> checked org.apache.edgent.test.connectors.file.FileStreamsTest and didn't
> find such scenario). But I found my unit test always failed at reading the
> content of newly appeared files. But if the files are pre-existing, it works.
>
> I attached two files. To reproduce this issue, you can run
> testDirectoryWatcherOrder in CopyOfFileStreamsTest.java. And you will see the
> following error. FileReaderApp.java is a standard alone version of the above
> test scenario - it works well (once you start it, generate some files with
> content in the directory, you can see the file content are printed in
> console).
>
> So could you please let me know if this is a defect of edgent Tester or my
> usage mistake?
