Advanced testing for Rust applications

No application is an island: you need to interact with third-party APIs, databases and who knows what else. Testing those interactions is tricky, to say the least! This workshop will focus on expanding your Rust testing toolkit, going beyond the basic techniques you're already familiar with. At the end of this workshop, you'll have a strategy to test most of the scenarios that are relevant for a complex Rust application.

The course assumes you have a good understanding of Rust's basic concepts and want to move beyond the built-in testing toolkit. If you run into any issue with the assumed level of Rust knowledge, please ping us and we'll sort it together!

Requirements

• Rust (follow instructions here).
  If Rust is already installed on your system, make sure you are running on the latest compiler version (cargo --version).
  If not, update using rustup update (or another appropriate command depending on how you installed Rust on your system). You must have rustup installed (check with rustup --version).
• (Optional) An IDE with Rust autocompletion support. We recommend one of the following:
  • RustRover;
  • Visual Studio Code with the rust-analyzer extension.
