100 Days of Rust : Day 9 (Testing)

I continued reading Command Line Applications in Rust

Learnt that testing is easy. Any function that has #[test] above it, will be found (across any files) and used by cargo test

Couple of interesting crates :

• exitcode
  • It has quite well defined exit codes. They come from FreeBSD
  • I wish other languages / frameworks had something similar
• proptest
  • is a property testing framework
  • Based on python’s Hypothesis
  • I need to spend time actually trying this
• human-panic
  • Generates report file on panic
  • Shows nice (if a bit long) message to the user, asking them to (optionally) email the report file to the developer 🤯

Things to explore:

• Write code across files.
  • So far my code is contained within src/main.rs 😄
• Then move the tests in a separate files.
