Add tests

[louischan-oursky]

Add tests for the selection or matching logic

The tests should be easy to read, and easy to add

func TestSelection(t *testing.T) {
  test := func(configYAML string, expectedName string) {
    // Parse the configYAML, call the function, and assert the result
  }
  test(`
# The YAML here
`, "foobar")
  test(`
# The YAML here
`, "foobar")
}
