Randoop - An Automatic unit test case generation tool for Java

In this video, I explained Randoop -An Automatic unit test case generation tool for Java.

Considering that installation folder for randoop is D:\randoop-3.0.8
Randoop command to get help on unit test generations :

--Run Randoop with default setting to generate tests automatically


-- Generate tests with input limit and output limit

--generate tests and limit the tests to the file

---generate tests and output test to the particular directory

--generate tests for classes defined in the file

superb way of explaining sir..hatts blessed

[vaibhavjadhav]

superb way of explaining!!! however example java file you have taken doesnt have any jar dependency like log4j/spring-core etc in such cases its throwing noclassdeffounderror.

If i need to adjust the randoop options to meet these requirements. what should i have to do?
1. not generate regression tests.
2. Consider unchecked exceptions thrown to be bugs.
3. Consider a NullPointerException thrown on any input to be a bug.
4. Consider a outofmemoeryerror or stackoverflowerror thrown to be expected beahvior, and not a bug.

I have tried the steps you have stated but i'm getting an error saying that invalid flag for --testclass.Would you be able to help me?

Error: No class with name "Message" found on the classpath
This is most likely a problem with the classpath. It may be wrong, or
it is formatted incorrectly on the command line. The other possibility
is that the wrong class name is given.

Hi SivaReddy,
When we are trying to work with myclasses.txt, we are getting below error message. Could you please suggest what would be the reason, am unable to figure what is the issue is

-classpath randoop.main.Main gentests --classlist=myclasses
Randoop for Java version 4.2.3.

Error while reading class names file myclasses: myclasses (The system cannot find the file specified)
Note: As per the video, I have done it, for individual classes it is working fine. But when it comes to myclasses.txt file, it is throwing an exception.

How do you specify what folder you want the generated J-unit files to go in?

[quynhtrangle]

Hi! Thanks for your video. I think that you use Randoop fluently. Do you know how to generate for a project which uses outside libraries? I need to use apache-commons-math3 libs but I can't generate a unit test. Can you help me if you know?
