The previous slide-size.test.ts was refactored and a slide class was implemented for convenience. The test now checks the playground size (if available on that slide) by checking if scrollbars are visible. To make this test more efficient, the mocha before() hook is used to load the slide once and check with all relevant tests before loading the next slide.
Testing Comprehensive Rust
The course material contains JS code that can break and needs to be checked for
functionality. Examples are theme/speaker-notes.js or theme/book.js.
Comprehensive Rust is using webdriverIO and the webdriverIO Expect API in combination with Mocha. WebdriverIO is taking care of accessing the webpage with a real browser and can access the state of the page so behavior can be asserted.
The Static Server Service is
used mainly in the CI to serve the book on port
localhost:8080 such that the test runner can access it. This mode is used when
npm start or npm test is executed.
Tip: Use
cargo xtask web-teststo run the tests in this directory from anywhere in the repository.
For local testing and quick iterations it is possible to use mdbook serve
which creates a small HTTP server on port 3000 by default. There is a special
config that is invoked with npm run test-mdbook that uses
http://localhost:3000
