Hello
may be it is a trivial question but I could not find any usable answer to
the following requirement therefore I thought that
surely some of you have the answer
Let's assume I have some code like follows:
func (obj *myObjStruct) MyFn(fsPath string) (myRetType, error) {
cpath := path.Join(fsPath, "subdir", "input.txt")
fh, err := os.Open(cpath)
if err != nil {
log.Error(fmt.Sprintf("Got error %#v", err))
return nil, err
}
defer fh.Close()
scanner := bufio.NewScanner(fh)
for scanner.Scan() {
inLine := scanner.Text()
...
How should I proceed to mock the os.Open and scanner.xxx calls so that I
can exercise the remaining parts of the code (... above)
May be I need to rewrite this function a little bit before being able to do
so but I obviously would not agree to lose the benefits of defering
fh.Close() call
Thanks for any advice/pointer/...
