Rust: Crafting Code through Rigorous Testing-Rust Testing Tool

Example

Testing individual functions to ensure they perform as expected. For instance, a unit test for a function that parses URLs might include cases for valid URLs and various invalid URLs to ensure the parser behaves correctly.

Scenario

In a web server project, unit tests verify each part of the request parsing logic independently, from handling HTTP headers to parsing query parameters.

Example

Testing multiple components of a software project together to ensure they work harmoniously. For example, an integration test could verify the interaction between user authentication and profile retrieval components.

Scenario

In a customer management system, integration tests ensure that after a new customer is added through the API, the customer details are retrievable and correctly linked to their transactions.

Example

Ensuring that examples in documentation actually compile and work as shown. A test might extract code snippets from markdown files and execute them to verify correctness.

Scenario

For a library offering JSON handling capabilities, documentation tests verify that the code snippets provided in the documentation compile and produce the expected outputs, thus ensuring that documentation stays up-to-date with the codebase.
