Class ExpressionEvalTest

java.lang.Object
com.singularsys.jeptests.system.ExpressionEvalTest
public class ExpressionEvalTest extends Object
This class is designed for testing the validity of Jep evaluations. Expressions from a text file are evaluated with Jep in pairs of two, and the results are compared. If they do not match, the two expressions are printed to standard output.

Take for example an input text file containing the two lines 

1+2
3.
The expressions '1+2' and '3' are evaluated with Jep and the results compared.
