Last updated 14 September 2026

What is Testing?

Rust has built-in testing support through cargo test and the #[test] attribute. Test functions use assertion macros like assert!, assert_eq!, and assert_ne! to verify expected behavior. Organize tests with unit tests, integration tests, and documentation tests for comprehensive coverage.

Testing: common questions

Can I learn Testing in Hindi?

This lesson is written in English. Once you sign in, open it in the interactive course and ask the AI tutor to explain Testing in Hindi or Hinglish. The tutor answers from this lesson’s own text, so it stays on the syllabus, and it runs on your own Google, OpenAI or Anthropic key.

Is this Testing tutorial for beginners?

It is lesson 24 of 122 in the free Rust roadmap, in stage 5, Testing. If you are new to Rust, start from stage 1 and come back here in order; if you already know the earlier stages, this lesson stands on its own.
