Unable to load class "ConfigureJob.java" due to exception: java.lang.ClassNotFoundException

[Emanuele Benza]

Hi Michael,

I'm having a problem getting randoop to generate test classes. I am using version 4.2.4 and after inserting my .class file inside a folder I launched randoop with this command: java -classpath C: \ Users \ Administrator \ Desktop \ randoop-4.2.4 \ bin; C: \ Users \ Administrator \ Desktop \ randoop-4.2.4 \ randoop-all-4.2.4.jar randoop.main.Main gentests --testclass = ConfigureJob.java The ConfigureJob.class file is present in the path C: \ Users \ Administrator \ Desktop \ randoop-4.2.4 \ bin The mistake that gets me out is

Randoop for Java version 4.2.4.
Unable to load class "ConfigureJob.java" due to exception: java.lang.ClassNotFoundException: ConfigureJob.java
Will try to generate tests for 0 out of 1 classes.
You provided no methods to test, so no tests for them can be generated.

There are no methods for Randoop to test.  See diagnostics above.  Exiting.

What can I do to solve the problem?

Thank you very much
