Examples of using cargo test

cargo test - run all tests, which are not ignored. Their stdout is not shown/printed.

cargo test --help - see the documentation of cargo test. Note that it does not display the [test options].

cargo test top_level_mod::tests::test_fn_name -- --exact - run a single test [^1]. The --exact argument ensures that similar test names won't be executed [^2]. Note that the path does not include the crate name.

	// I work in VS Code. It has a Run Test button above every test.
	// I have a test that renders an HTML page with Handlebars.
	// I'd like to open the page in the browser if the test is called directly.
	// If the test is called indirectly (but rather as a result of `cargo test`), I don't want the test to open the browser.
	// The code below demonstrates how it can be achieved.
