Mockator throws exception "java.lang.reflect.invocationTargetException"

[JoergMoeller]

Expected Behavior

Converting a C function into a Mock function liked described here https://www.cute-test.com/guides/mocking-with-cute/#mockfunctions

Actual Behavior

Setup:
Software under Test: C++ Static Libraray, C++ 11, name: SUT
Test Code: Cute Project, Cute Project, C++ 11, name: testSUT, linked to SUT project

1.) Problem:
After selecting C function from SUT code ( myfunc ) and selecting "Source / Mock Function", the dialog "New Cute Suite File" pops up. After naming the new test suite "xyz" and selecting "Link to runner" it doesn't provide a runner, though one is present.

2.) Problem:
After hitting the "Finish" button it throws an expecetion "java.lang.reflect.InvocationTargetException". No files are created.

CUTE or CUTE Eclipse Plug-in Version, Operating System and Compiler

I've attached a zip archive of the Workspace, the error log file and screenshots of the error message.

I've also tried with the latest CEvelop version, 1.10.1 Release, with the same behaviour.

If you need more information I'll happily provide it.

Have you tried to compile/parse the .c file as C++? Internally the C-AST and the C++-AST differ and for plug-ins like Mockator that we do not push upstream to Eclipse-CDT we usually only implement features for C++. If you want to know why, send me an email.

either rename sut.c to sut.cpp or set the file type .c to be C++ code and try again.

Thanks for the detailed report! That is very helpful to reproduce the problem. Even though we don't specifically to aim for C support, we should handle error cases more gracefully than just throwing exceptions. We'll look into it. Maybe with the correct abstration on the code representation we might get it to work with C easily.

Hello, thanks for the quick reply. Actually we are developing C Code for embedded automotive ecus, so there’s little possibility to change the SUT.c to SUT.cpp so either suggested won’t work.

Hello, actually the CUTE stuff is cool. We are really interested in using it. We also have a problem with installing the Example project. It’s also throwing exception. Do you want me to create another ticket for it? It’s the same behavior in Cute and Cevelop.

You do not need to change the .c, just make Cevelop/Eclipse-CDT into parsing it as C++ for a try (settings->file types-> project-specific...

Hello Joerg,

I looked at your problem more closely and was able to reproduce the issue. I also checked the behaviour in a similar scenario but using a C++ project instead of a C project. In that case, the refactoring worked as expected.

In the upcoming release of CUTE, we fixed the issue in the UI, where we disable the checkbox for the runner selection when no runners are present. This prevents the issue with the java.lang.reflect.invocationTargetException.

However, adding C support to the refactoring requires large scale changes to the plugin and is therefore not planned for the near future.

Best Regards
Mario

Hello, I#ve tried what you proposed, but I’m not sure if I understand correctly. Here’s what I was trying to achieve: [cid:image001.png@01D4BD2A.D2CA33D0] Unfortunately it seems that I can’t change the file type. Maybe I’m at the wrong place?

Hello, thanks for the feedback and your effort in resolving the issue. Actually we don’t expect full refactoring capabilities. We would very much appreciate if “mock function” would work with plain C code.

Unfortunately, Mockator relies on the foundation of C++ refactoring and thus 'just' means a lot of work, because as said above the C language representation within Eclipse CDT is separate from C++.

I could not see the image showing what you tried with my suggestion. Could you upload the screenshot directly to github instead of replying to the email notification?
