FAQPage Schema
What is the best way to measure code coverage in Go tests?

Benchmarks in Go tests are created using functions prefixed with `Benchmark` and executed via `go test -bench`. They measure code performance and memory allocations to help optimize critical application paths.

How does fuzzing work in Go 1.22+?

Fuzzing in Go 1.22+ uses functions prefixed with `Fuzz` to automatically generate random inputs targeting edge cases. This testing technique finds vulnerabilities and unexpected panics by continuously mutating test data.

Does this support mocking and test helpers for Go unit tests?

Yes, this supports implementing mocking, fakes, and test helpers for Go unit tests. These patterns isolate dependencies and simplify complex setups, ensuring maintainable and readable test suites.

When should I use subtests in Go?

Subtests in Go are used to group related test cases logically within a single test function. They provide granular control over test execution and failure reporting, improving the structure of unit tests.
