示例1: MockSnap

// MockSnap puts a snap.yaml file on disk so to mock an installed snap, based on the provided arguments.
//
// The caller is responsible for mocking root directory with dirs.SetRootDir()
// and for altering the overlord state if required.
func MockSnap(c *check.C, yamlText string, snapContents string, sideInfo *snap.SideInfo) *snap.Info {
	c.Assert(sideInfo, check.Not(check.IsNil))

	// Parse the yaml (we need the Name).
	snapInfo, err := snap.InfoFromSnapYaml([]byte(yamlText))
	c.Assert(err, check.IsNil)

	// Set SideInfo so that we can use MountDir below
	snapInfo.SideInfo = *sideInfo

	// Put the YAML on disk, in the right spot.
	metaDir := filepath.Join(snapInfo.MountDir(), "meta")
	err = os.MkdirAll(metaDir, 0755)
	c.Assert(err, check.IsNil)
	err = ioutil.WriteFile(filepath.Join(metaDir, "snap.yaml"), []byte(yamlText), 0644)
	c.Assert(err, check.IsNil)

	// Write the .snap to disk
	err = os.MkdirAll(filepath.Dir(snapInfo.MountFile()), 0755)
