-faultlocalization cocospoon

[KwanghoKim]

Hi

I have one more question.

I checked to "List of extension points of Astor"(https://github.com/SpoonLabs/astor/blob/master/docs/extension_points.md)
and then So I added "-faultlocalization cocospoon" like below command line.

But, error message occurs.

I want to change faultlocalization strategy and compare between gzoltar and cocospoon.
I found source code about faultlocalization property, but I don't know what to do for testing using cocospoon.

(src/main/java/fr/inria/astor/core/solutionsearch/AstorCoreEngine.java)
protected void loadFaultLocalization() throws Exception {

            // Fault localization
            String flvalue = ConfigurationProperties.getProperty("faultlocalization").toLowerCase();
            if (flvalue.equals("gzoltar")) {
                    this.setFaultLocalization(new GZoltarFaultLocalization());
            } else if (flvalue.equals("cocospoon")) {
                    this.setFaultLocalization(new CocoFaultLocalization());
            } else
                    this.setFaultLocalization(
                                    (FaultLocalizationStrategy) PlugInLoader.loadPlugin(ExtensionPoints.FAULT_LOCALIZATION));

    }

(Error message)

Hi @KwanghoKim

Thanks for your interest on Astor.
Cocospoon code is quite experimental. We haven't detailed tested that mode.
However, we are currently working on a new fault localization approach that we are integrating to Astor.
In few weeks, it will be ready to be used.
Thanks

Matias

Thank you so much for your speedy response..! Can I ask one more? How can I check correctness after test? (Is there on output folder? I couldn't find in json file.) 2021년 8월 18일 (수) 오후 6:30, Matias Martinez ***@***.***>님이 작성:

Hi @KwanghoKim

How can I check correctness after test?

Do you mean correctness of patches?
All patches generated by Astor are plausibles, and pass all test cases contained in the app under repair, but yet those can be incorrect as the test cases can be weak.

Thank you so much @martinezmatias ..!
