[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] 
[INFO] [stderr] * /opt/crater/workdir/tests/test_recursive.rs
[INFO] [stderr] * /opt/crater/workdir/tests/test_zk.rs
[INFO] [stderr] * /opt/crater/workdir/tests/test_cache.rs
[INFO] [stderr] 
[INFO] [stderr] This is likely to break cargo build or cargo test as these files may not be
[INFO] [stderr] ready to be compiled as a test target today. You can future-proof yourself
[INFO] [stderr] and disable this warning by adding `autotests = false` to your [package]
[INFO] [stderr] section. You may also move the files to a location where Cargo would not
[INFO] [stderr] automatically infer them to be a target, such as in subfolders.
