Go Test

Go has a built-in testing framework in the testing package. It follows Go's effective, minimalist philosophy: no magic, just code.

When to Use

• Go Standard Library Testing: Official, zero-dependency testing toolchain built directly into the Go runtime.
• Table-Driven Unit Tests: Structuring comprehensive test suites with multiple input/output scenarios cleanly in Go.
• Race Condition Detection: Identifying concurrent memory access bugs using go test -race.
• Benchmarking & Memory Profiling: Measuring operations per second and heap allocations with go test -bench.

Quick Start

// main_test.go
package main

import "testing"
