What is the significance of using the '-race' flag with 'go test' command in Go?
- Detects data race conditions in concurrent Go programs
- Disables race condition detection
- Executes tests in a random order
- Simulates race conditions for testing
The '-race' flag, when used with the 'go test' command in Go, enables race condition detection during the execution of concurrent Go programs. Race conditions occur when two or more goroutines access shared data concurrently, and at least one of the accesses is a write operation. This flag instruments the Go program's code to track accesses to shared variables and detects potential data races during runtime. It helps in identifying and fixing concurrency bugs early in the development cycle, ensuring the correctness and stability of concurrent Go programs.
