-----------------------------------------
I deleted system directory in between each run of the test. That's fine.
I try to write a method to test the public long length() method of
jarDBFile.java as follows.
public void testlength() throws Exception{
JarStorageFactory storageFactory=new JarStorageFactory() ;
File jarFile = SupportFilesSetup.getReadOnly("dclt.jar");
final String path=jarFile.getPath();
JarDBFile jdf=new JarDBFile( storageFactory, path);
final File backupDir = SupportFilesSetup.getReadWrite("dbreadonly");
final String db = getTestConfiguration().getDefaultDatabaseName();
File file=new File(backupDir, db);
if(!file.isDirectory()){
if(jdf.length()==0){
assertEquals(jdf.length(),0);
}
else{
assertTrue(jdf.length()>0);
}
}
}
For this, I need to make some classes public. I know it's not allowed and
wrong.
Bryan, you said that the DirFile.java is tested well by our current test suite.
Can you show me a method and its appropriate test methods for this class? So,
I can look at it and try my best to write some test methods. Still, I couldn't
understand , how to test a method which is not public or not accessible
directly via testing classes.
Thanks,
Ahsan
