binding/c: Implement test framework

[Xuanwo]

Test framework should do the following things:

• Read OPENDAL_TEST as the scheme to test.
• Read all env values OPENDAL_{scheme}_{key}={value} and use the map to construct the operator.
• Perform the test logic upon operator, for example, write a file and read it back to verify checksum.

The usage will be like:

OPENDAL_TEST=memory make behavior_test

Tasks

• [x] Add capability support to allow more test cases
• [ ] Implement test framework
• [ ] Add random root support

Hi, it seems like you have a lot on your plate with opendal. How about tackling this issue later if no one else shows interest?

I think we should split the test framework part with the capability part. And can first support the bdd test on different services IMO.

I'm sure that you don't want to do this: we have over 30+ services and every service may have more than one setup.

I mean we can just set up using the environment variables just like other bindings test framework right?

But of course we can setup the framework and capabilities first.

I didn't get this. If this has been implemented, you have done 80% work of the test framework 🤣

Lol that's true🤣 I can do the capabilities part first. We can see for a while if anyone is interested in this task.
