[INFO] [stderr] warning: An explicit [[test]] section is specified in Cargo.toml which currently
[INFO] [stderr] disables Cargo from automatically inferring other test targets.
[INFO] [stderr] This inference behavior will change in the Rust 2018 edition and the following
[INFO] [stderr] files will be included as a test target:
[INFO] [stderr]
