Cargo Travis

Record total test coverage across in-crate and external tests, and upload to coveralls.io.

The goal is to eventually have feature parity with the assumed-dead travis-cargo

To avoid problems like this one, we link against the cargo crate directly and use its low-level operations. This should be much more reliable than the stdout capture approach. On the other hand, the cargo crate isn't stable, leading to things like this.

Installation

cargo install cargo-travis export PATH=$HOME/.cargo/bin:$PATH

Example

A possible travis.yml configuration is:

```yaml sudo: false language: rust

Dependencies of kcov, used by coverage

addons: apt: packages: - libcurl4-openssl-dev - libelf-dev - libdw-dev - binutils-dev - cmake sources: - kalakris-cmake

run builds for all the trains (and more)

rust: - nightly - beta # check it compiles on the latest stable compiler - stable # and the first stable one (this should be bumped as the minimum # Rust version required changes) - 1.0.0

before_script: - | cargo install --force cargo-travis && export PATH=$HOME/.cargo/bin:$PATH

the main build

script: - | cargo build && cargo test && cargo bench && cargo doc

after_success:

measure code coverage and upload to coveralls.io

• cargo coveralls ```
