Unable to run Randoop on a maven project

Question

Im trying to run Randoop for a java application based out of Maven. The project has been compiled successfully through cmd through

G:\javapplic\a12>mvn compile

The java files which I wanted to create test on are present on : G:\javapplic\a12\src\main\java\org\jaffa\datatypes\configurer

I used randoop to generate classes present inside the folder: G:\javapplic\a12\target\classes\org\jaffa\datatypes\configurer

Therefore in cmd I used the following code to generate the test cases:

java -Xmx3000m -classpath G:\javapplic\a12\target\classes\org\jaffa\datatypes;G:\New\randoop-all-4.2.2.jar randoop.main.Main gentests --testclass=org.jaffa.datatypes.configurer.MybatisConfigurer

enter image description here This is the path of the classes present

SO after I run the above cmd command I get the following error:

    G:\javapplic\a12>java -Xmx3000m -classpath G:\javapplic\a12\target\classes\org\jaffa\datatypes;G:\New\randoop-all-4.2.2.jar randoop.main.Main gentests --testclass=org.jaffa.datatypes.configurer.MybatisConfigurer

So if anyone knows a workaround to make Randoop work on a maven project please do let me know

Answer 1

This question already has an answer here. I'll repeat the answer here, but in the future please ask your question to one forum at a time.

This question has nothing to do with Maven.

The answer to your question is in the log you provided. You need to fix your classpath.

Your Randoop invocation specifies only one class to test:

--testclass=org.jaffa.datatypes.configurer.MybatisConfigurer

However, that class was not found on the classpath:

Unable to load class "org.jaffa.datatypes.configurer.MybatisConfigurer" due to exception: java.lang.ClassNotFoundException: org.jaffa.datatypes.configurer.MybatisConfigurer

Thus, Randoop tries to test 0 classes:

Will explore 0 out of 1 classes

It can't create tests for any of those 0 classes, so it exits:

There are no operations to test. Exiting.

If you fix your classpath, you will be able to run Randoop.
