Class FileResolver

java.lang.Object
  org.unitils.core.util.FileResolver

public class FileResolver
extends Object

Resolves the location for a file with a certain name.

By default, the file name is prefixed with the package name (. replaced by /).
E.g. MyFile.xml becomes com/myPackage/MyFile.xml

If a file name starts with a / it will not be prefixed with the package name.
E.g. /MyFile.xml remains /MyFile.xml

Package name prefixing can be disabled using the prefixWithPackageName property.
prefixWithPackageName=false => MyFile.xml remains MyFile.xml

If a path prefix is specified using the pathPrefix property it is added to the file name.
Examples:

pathPrefix=myPathPrefix: MyFile.xml becomes myPathPrefix/com/myPackage/MyFile.xml
pathPrefix=myPathPrefix: /MyFile.xml becomes myPathPrefix/MyFile.xml

If the path prefix starts with '/', the file name is treated absolute, else it will be treated relative to the classpath.

Examples:

path prefix /c:/testfiles --> looks for c:/testfiles/MyFile.xml on the file system path prefix testfiles --> looks for testfiles/MyFile.xml on the classpath
