Method Detail

withPrefix

public static java.io.File withPrefix(java.lang.String prefix,
                                      java.nio.file.attribute.FileAttribute<?>... attrs)

Creates a temporary directory.

The parent directory for the created is obtained from the system property java.io.tmpdir.

The prefix is used by the underlying JDK implementation and is NOT guaranteed in the name of the created directory name.

Parameters:

prefix - this value would be used for generating the name of the created directory, cannot be empty, or blank

attrs - an optional list of file attributes to set atomically when creating the directory

Throws:

java.lang.IllegalStateException - if the directory could not be created

forClass

public static java.io.File forClass(java.lang.Class<?> testSuite,
                                    java.nio.file.attribute.FileAttribute<?>... attrs)

Creates a temporary directory for the passed test suite class.

The parent directory for the created is obtained from the system property java.io.tmpdir.

Implementation may use a simple name of the passed class as the prefix for the name of the generated directory, but this is NOT guaranteed.

Parameters:

testSuite - the test suite class which needs the temporary directory

attrs - an optional list of file attributes to set atomically when creating the directory

Throws:

java.lang.IllegalStateException - if the directory could not be created
