Automatically generate tests from your Go source code.
```go
package main
func Sign(x int) int {
if x < 0 {
return 1
}
if x > 0 {
return 2
}
return 3
}
```
```bash
go run dandy.go -- myfile.go
```
```go
func TestSignXIsLessThan0(t *testing.T) {
result := Sign(-1)
if result != 1 {
t.Error("Failed")
}
}
func TestSignXIsGreaterThan0(t *testing.T) {
result := Sign(1)
if result != 2 {
t.Error("Failed")
}
}
func TestSign(t *testing.T) {
result := Sign(0)
if result != 3 {
t.Error("Failed")
}
}
```
The tests are rendered from the intermediate JSON format that provides
information on individual paths, steps taken, input and return values:
