single file test support

[abritov]

Is it possible to add a file argument to test command like that: c3c test src/foo.c3 so it can test single file?

Use c3c compile-test src/foo.c3 perhaps?

[abritov]

Thank you for reply!
I tried compile-test command and it could not find imports:

~/c/c/hello ❱ ../c3c test
Program linked to executable 'build/testrun'.
Launching ./build/testrun
------------- TESTS -------------
Testing bar::test_imports .. [ok]

1 test run.

Test Result: ok. 1 passed, 0 failed.
Program completed with exit code 0.
~/c/c/hello ❱ ../c3c compile-test src/bar.c3
1: module bar;
2: import foo;
          ^^^
(/home/fitumi/code/c3/hello/src/bar.c3:2:8) Error: No module named 'foo' could be found, did you type the name right?

[lerno]

Well, did you include the file with the foo module on the command line?

[abritov]

I did not. I expect test command to work like in cargo, where you can run a single test:
cargo test tests::test_rc4
The point is to bind this command to hotkey in vim/emacs. I'm not sure how to do it if I need to pass additional arguments

This is not available yet. I was thinking there wasn't a huge need for it since the test runner is configurable. You can have a look at fn bool default_test_runner() in runtime.c3. For one that function could be changed to take arguments, such as the tests to run. The intention was that an IDE would swap the test runner for its own implementation for maximum control.

[abritov]

Can you provide an example of how IDE's would swap the runner? For my own experimenting I can make a fork, but how it will work for IDE's?

[lerno]

There is the --testfn command line option. Use this to pass in the name of the alternative tester function.
