示例1: AssertExportedFields
func (s *MigrationSuite) AssertExportedFields(c *gc.C, doc interface{}, fields set.Strings) {
expected := getExportedFields(doc)
unknown := expected.Difference(fields)
removed := fields.Difference(expected)
// If this test fails, it means that extra fields have been added to the
// doc without thinking about the migration implications.
c.Check(unknown, gc.HasLen, 0)
c.Assert(removed, gc.HasLen, 0)
}示例2: removeDiff
// removeDiff removes every path in oldManifest that is not present in newManifest.
func (d *manifestDeployer) removeDiff(oldManifest, newManifest set.Strings) error {
diff := oldManifest.Difference(newManifest)
for _, path := range diff.SortedValues() {
fullPath := filepath.Join(d.charmPath, filepath.FromSlash(path))
if err := os.RemoveAll(fullPath); err != nil {
return err
}
}
return nil
}示例3: TestUninitialized
func (stringSetSuite) TestUninitialized(c *gc.C) {
var uninitialized set.Strings
c.Assert(uninitialized.Size(), gc.Equals, 0)
c.Assert(uninitialized.IsEmpty(), gc.Equals, true)
// You can get values and sorted values from an unitialized set.
AssertValues(c, uninitialized)
// All contains checks are false
c.Assert(uninitialized.Contains("foo"), gc.Equals, false)
// Remove works on an uninitialized Strings
uninitialized.Remove("foo")
var other set.Strings
// Union returns a new set that is empty but initialized.
c.Assert(uninitialized.Union(other), gc.DeepEquals, set.NewStrings())
c.Assert(uninitialized.Intersection(other), gc.DeepEquals, set.NewStrings())
c.Assert(uninitialized.Difference(other), gc.DeepEquals, set.NewStrings())
other = set.NewStrings("foo", "bar")
c.Assert(uninitialized.Union(other), gc.DeepEquals, other)
c.Assert(uninitialized.Intersection(other), gc.DeepEquals, set.NewStrings())
c.Assert(uninitialized.Difference(other), gc.DeepEquals, set.NewStrings())
c.Assert(other.Union(uninitialized), gc.DeepEquals, other)
c.Assert(other.Intersection(uninitialized), gc.DeepEquals, set.NewStrings())
c.Assert(other.Difference(uninitialized), gc.DeepEquals, other)
// Once something is added, the set becomes initialized.
uninitialized.Add("foo")
AssertValues(c, uninitialized, "foo")
}
