Go fuzzing tests the resiliency of your code by continuously generating random inputs to uncover edge cases and crashes. You implement fuzzing by defining a fuzz target function and running it with the native Go test command.

Measuring Go code coverage involves executing tests with the coverage flag enabled to generate a profile report. This report identifies exactly which lines of code were executed during testing, highlighting untested paths for better reliability.

The best way to mock dependencies in Go is by using interface-based mocking to isolate the code under test. By defining interfaces for external dependencies, you can easily substitute real implementations with mock objects during unit testing.

Go benchmarks measure function performance by placing test functions in a benchmark file and executing them using the benchmark command. This repeatedly runs the target code to accurately calculate the average execution time and memory allocations.

Go testing supports HTTP handler testing by utilizing the standard library's testing utilities to simulate web requests and record responses. These tests integrate seamlessly into CI/CD pipelines via command-line execution to automate quality checks.
