How deeply does Learn Go with Pocket-Sized Projects cover test fixture?

Explains fixture placement and strict comparison, but stops short of whitespace-insensitive HTML testing.

Test fixture

As explained in Learn Go with Pocket-Sized Projects

A test fixture is prepared input or reference data used to evaluate software under test.

A test fixture is prepared input or reference data used to evaluate software under test. For generated HTML, store the expected output as a file in testdata; this reference is commonly called a golden file. section 11.1.1

A practical fixture-based HTTP test follows these steps:

Create an httptest response recorder and invoke the handler. section 11.1.1
Compare the generated body with the fixture, while recognizing that strict equality makes whitespace changes significant. section 11.1.1

Golden HTML fixture

Keep the expected page in testdata/index.html rather than embedding HTML in a Go test. The test then compares the handler response with that reference and detects output changes automatically. section 11.1.1
