> 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?
