@ -0,0 +1,25 @@
This folder contains a V project,
intended to be used as a demonstration
for how to test functions defined inside
a main module.
See my_test.v and my_other_test.v .
These files work as any other internal module tests,
i.e. they do `module main` at their top, so that v knows,
that they are internal tests, and for which module they apply.
When you do `v my_test.v`, v will try to find other *.v files in
the same folder that also have `module main` at their top,
then it will process them and process the my_test.v file too.
The v `fn main(){}` function that you most likely also have will get
compiled as normal to `void main__main(){...}`, but it will NOT be
called by anything, so it will not mess up your tests.
Instead, your test_ functions will get called inside the generated
`int main(){...}` test runner, just like it is the case with all _test.v
files (internal or external ones).
NB: each _test.v file is compiled separately from all other _test.v
files, so you can have conflicting test_ functions in them without a
problem too.
