Unable to use Randoop testjar

Question

I have a folder containing randoop-all-4.3.0.jar and project.jar. I want to test the entire jar as a whole using java -classpath randoop-all-4.3.0.jar randoop.main.Main gentests --testjar=project.jar but I am getting the following error:

Randoop for Java version 4.3.0.

AppInterface was read from project.jar but was not found on classpath.  Ensure that project.jar is on the classpath.  Classpath:
randoop-all-4.3.0.jar

What does this error mean?

Answer 1

Your command java -classpath randoop-all-4.3.0.jar provided a classpath that contains Randoop but does not contain your code.

As described in the "Running Randoop" section of the Randoop manual, a typical invocation is

    java -classpath myclasspath:${RANDOOP_JAR} randoop.main.Main ...

In your case, that would be

    java -classpath project.jar:${RANDOOP_JAR} randoop.main.Main ...
