Basics
How testing works in Go
For each file X.go a corresponding test named X_test.go should contain unit tests for that code.
To run tests, just use the built-in test command in go: go test
Example
Take this simple function as an example:
package main
import (
"fmt"
)
// Return the square of a number
func square(x int) (result int) {
return x * x
}
func main() {
fmt.Println("Hello World")
}
We can write a corresponding test:
package main
import (
"testing"
)
func test_square(t *testing.T) {
if test_square(2) != 4 {
t.Error("Error testing square(): did not return correct result")
}
}
