From eb59b5925efdb9b8bf414d11877b15c0e500e3a9 Mon Sep 17 00:00:00 2001 From: James Bardin Date: Fri, 27 Jan 2017 11:28:27 -0500 Subject: [PATCH] Fix some tests, and make rest fail with good errs Having the state files always created for locking breaks a lot of tests. Most can be fixed by simple checking for state within a file, but a few still might be writing state when they shouldn't. --- command/meta_backend_test.go | 130 ++++++++++++++++++++++------------- command/refresh_test.go | 4 ++ 2 files changed, 86 insertions(+), 48 deletions(-) diff --git a/command/meta_backend_test.go b/command/meta_backend_test.go index 89456e38f..aaa81eaec 100644 --- a/command/meta_backend_test.go +++ b/command/meta_backend_test.go @@ -1,6 +1,7 @@ package command import ( + "io/ioutil" "os" "path/filepath" "strings" @@ -43,15 +44,29 @@ func TestMetaBackend_emptyDir(t *testing.T) { // Verify no backup since it was empty to start if _, err := os.Stat(DefaultStateFilename + DefaultBackupExtension); err == nil { - t.Fatalf("err: %s", err) + t.Fatal("expected error") } // Verify no backend state was made - if _, err := os.Stat(filepath.Join(m.DataDir(), DefaultStateFilename)); err == nil { - t.Fatalf("err: %s", err) + if !isEmptyState(filepath.Join(m.DataDir(), DefaultStateFilename)) { + t.Fatal("state created") } } +// check for no state.
