A testing cleanup. This pull request replaces `os.MkdirTemp` with `t.TempDir`. We can use the `T.TempDir` function from the `testing` package to create temporary directory. The directory created by `T.TempDir` is 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 ```go func TestFoo(t *testing.T) { // before tmpDir, err := os.MkdirTemp("", "") require.NoError(t, err) defer os.RemoveAll(tmpDir) // now tmpDir := t.TempDir() } ``` Signed-off-by: Eng Zer Jun <engzerjun@gmail.com>
