Code coverage data not getting uploaded successfully

[bjgill]

https://coveralls.io/github/killercup/cargo-edit would seem to suggest that coveralls has seen no coverage data since 2016.

We've currently got the following in `.travis.yml':

- env COVERAGE_TESTING=1 travis-cargo --only stable coveralls --no-sudo

Perhaps the environment variable is responsible?

Is the coverage data any good? Last I checked it was hard to tell if it was trustworthy or just a random number. I don't think the env on Travis has changed but I can check again. Benjamin Gill <notifications@github.com> schrieb am Sa. 23. Dez. 2017 um 10:41:

Also, once this is fixed, we should add the coveralls badge to the readme. — You are receiving this because you are subscribed to this thread.

I've found using kcov on Travis to be a constant source of frustration for my Rust projects, but I did get it working again for some of them. Here's an example travis config.

Some things to note:

• travis-cargo's coverage support has been broken for a long time, so you need to explicitly invoke kcov.
• kcov needs libiberty for --verify to work, so I had to add that to the apt packages list.
• kcov crashes dealing with source files that aren't part of your project, so I had to add --exclude-pattern=/.cargo --include-pattern=$PWD to make things work. (It's possible that the --include-pattern there is sufficient, I didn't test that.)
