A small and useful utility for tests so you can run your tests with multiple environments from inside the test functions.
The environment is set for the whole application while you use the wrapper, so running tests in parallel may have unexpected problems.
package main
import (
"fmt"
"os"
"github.com/ilijamt/envwrap"
)
func main() {
env := envwrap.NewStorage()
defer env.ReleaseAll()
oldVariable := os.Getenv("A_VARIABLE")
env.Store("A_VARIABLE", "test")
fmt.Println("ORIGINAL_VALUE=", oldVariable)
fmt.Println("A_VARIABLE=", os.Getenv("A_VARIABLE"))
env.Release("A_VARIABLE")
fmt.Println("A_VARIABLE=", os.Getenv("A_VARIABLE"))
}Should print
ORIGINAL_VALUE=
A_VARIABLE= test
A_VARIABLE=Removes all environment variables
package main
import (
"fmt"
"os"
"github.com/ilijamt/envwrap"
)
func main() {
fmt.Printf("Total items before new clean storage in environment: %d\n", len(os.Environ()))
env := envwrap.NewCleanStorage()
fmt.Printf("Total items in environment: %d\n", len(os.Environ()))
_ = env.ReleaseAll()
fmt.Printf("Total items in environment after release: %d\n", len(os.Environ()))
}Should print
Total items before new clean storage in environment: 55
Total items in environment: 0
Total items in environment after release: 55
