dataloc
Package dataloc provides functionality to find the source code location of table-driven test cases.
Example
import (
"fmt"
"github.com/motemen/go-testutil/dataloc"
)
func Example() {
testcases := []struct {
name string
a, b int
sum int
}{
{
name: "100+200",
a: 100,
b: 200,
sum: -1,
},
{
name: "1+1",
a: 1,
b: 1,
sum: 99,
},
}
for _, testcase := range testcases {
if expected, got := testcase.sum, testcase.a+testcase.b; got != expected {
fmt.Printf("expected %d but got %d, test case at %s\n", expected, got, dataloc.L(testcase.name))
}
}
// Output:
// expected -1 but got 300, test case at example_test.go:15
// expected 99 but got 2, test case at example_test.go:21
}

Overview ¶
Package dataloc provides functionality to find the source code location of table-driven test cases.
Example ¶
package main
import (
"fmt"
"github.com/motemen/go-testutil/dataloc"
)
func main() {
testcases := []struct {
name string
a, b int
sum int
}{
{
name: "100+200",
a: 100,
b: 200,
sum: -1,
},
{
name: "1+1",
a: 1,
b: 1,
sum: 99,
},
}
for _, testcase := range testcases {
if expected, got := testcase.sum, testcase.a+testcase.b; got != expected {
fmt.Printf("expected %d but got %d, test case at %s\n", expected, got, dataloc.L(testcase.name))
}
}
}
Output: expected -1 but got 300, test case at example_test.go:15 expected 99 but got 2, test case at example_test.go:21

Functions ¶
func L ¶
L returns the source code location of the test case identified by its name. It attempts runtime source code analysis to find the location by using the expression passed to dataloc.L(). So some restrictions apply:
- The function must be invoked as "dataloc.L".
- The argument must be an expression of the form "dataloc.L(testcase.key)" , where "testcase" is a variable declared as "for _, testcase := range testcases" , and "testcases" is a slice of a struct type , whose "key" field is a string which is passsed to L().
- or "dataloc.L(key)" , where key is a variable declared as "for key, value := range testcases" , and "testcases" is a map of string to any type , and "key" is the string which is passed to L().
See Example.
