escapeAssertion

public static java.lang.String escapeAssertion(java.lang.String s)

escapeAssertion escapes the dots in the assertion, because the expression evaluation doesn't support such variable names.

Parameters:

s - the value of the matcher and effect assertions.

Returns:

the escaped value.

removeComments

                                  java.util.List<java.lang.String> b)

arrayEquals determines whether two string arrays are identical.

Parameters:

a - the first array.

b - the second array.

Returns:

whether a equals to b.

array2DEquals

public static boolean array2DEquals(java.util.List<java.util.List<java.lang.String>> a,
                                    java.util.List<java.util.List<java.lang.String>> b)
