test: use T.TempDir to create temporary test directory
#151
Conversation
This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `ioutil.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

There was a problem hiding this comment.
It seems (*FileTestUtil).Cleanup() is useless with this patch and its references are removed.
Can we remove the Cleanup() since its work would be done implicitly?
NewFileTestUtil now uses t.TempDir() to create temporary directory so manual cleanup is no longer necessary. Signed-off-by: Eng Zer Jun <engzerjun@gmail.com>

@jasonliu747 No, I don't get this error on my Linux machine. This is probably a Mac specific issue, see https://unix.stackexchange.com/a/367012/376279 |
Could you try to fix this? I believe majority of programmer are using Mac for development. |

Ⅰ. Describe what this PR does
A testing cleanup.
This pull request replaces
ioutil.TempDirwitht.TempDir. We can use theT.TempDirfunction from thetestingpackage to create temporary directory. The directory created byT.TempDiris automatically removed when the test and all its subtests complete.This saves us at least 2 lines (error check, and cleanup) on every instance, or in some cases adds cleanup that we forgot.
Reference: https://pkg.go.dev/testing#T.TempDir
Ⅱ. Does this pull request fix one issue?
NONE
Ⅲ. Describe how to verify it
All tests should continue to pass. No leftover temporary directories when the tests finish.
Ⅳ. Special notes for reviews
