Print all rust code (inside project) executed by a single test

[Anton-4]

I'd like to compare the code executed by a test for two different commits. So I'm looking for a way to print every line of rust code executed by that test, excluding dependencies. Because code coverage is quite similar in nature, I thought I'd ask here for tips. Do you know of a tool that can do this or could I try to hack/use parts of tarpaulin to make this happen?

I'm obviously aware of stepping with a debugger but all the jumping back and forth is slow, and I'd prefer to be able to scroll through two "execution traces" side by side.

So the json output of tarpaulin gives you the file paths, lines and hits. If you have that json for two different commits you could compare it directly or use it plus a script to print out things the way you like. I also generate entirely self-contained HTML reports and in the past I've generated a report per commit and just stuck two browser windows side by side if that's acceptable

Cool, thank you @xd009642 ❤️

Can I run tarpaulin on a single test when there are multiple tests in a package? I tried some variations that work with cargo test but I could not get it to work.

cargo tarpaulin -- $TEST_NAME should work, the same as cargo test
