Method Detail

ensureOutputValidity

public static void ensureOutputValidity(java.lang.String resourcePath,
                                        java.lang.String outputFileName,
                                        java.lang.String testResourceFileName)
                                 throws java.io.IOException

Ensures output correctness with the given test resource file.

Parameters:

resourcePath - root folder for both resources.

outputFileName - output file name.

testResourceFileName - the test result file name.

Throws:

java.io.IOException - if the output is invalid.

ensureALSOutputValidity

public static void ensureALSOutputValidity(java.lang.String resourcePath,
                                           java.lang.String outputFileName,
                                           java.lang.String testResourceFileName)
                                    throws java.io.IOException

This method test the output validity of AlternatingLeastSquareITCase. Due to the floating point math error, the output of the test can be different every time. Thus we cannot compare plain text output, but have to check its numeric error.

Parameters:

resourcePath - path to resources.

outputFileName - name of output file.

testResourceFileName - name of the file to compare the outputs to.

Throws:

java.lang.RuntimeException - if the output is invalid.

java.io.IOException - exception.

deleteOutputFile

public static void deleteOutputFile(java.lang.String directory,
                                    java.lang.String outputFileName)
                             throws java.io.IOException

Delete output files.

Parameters:

directory - the path of file directory.

outputFileName - the output file prefix.

Throws:

java.io.IOException - if fail to delete.
