Hi folks. I don't want other than green tests in dev images, thus, I started to fix them as much as possible. There are a lot of failing tests of Nile (only fail in windows). The test is NSCompressedSourceStreamTest and I noticed something weird. If you look to tearDown method, it tries to remove two files that it actually were created in the setUp method. But it is weird because it tries to remove a file that actually exist and it is not being removed. If I debug in DosFileDirectory >> deleteFileNamed: localFileName ifAbsent: failBlock everything looks ok, but the file is not removed and the failBlock is executed :( localFileName -> 'testCompressedSourceStream.stc' (self fullNameFor: localFileName) asVmPathName -> 'C:\mariano\squeak\imagenes\Pharo1.0-10508-rc2dev10.01.2\testCompressedSourceStream.stc' And that file exist, as you can see in screenshot that I attach. Can someone help me with this ? Cheers Mariano
