Functions

func AssertImageMatches

func AssertImageMatches(t *testing.T, masterFilename string, img image.Image, msgAndArgs ...interface{}) bool

AssertImageMatches asserts that the given image is the same as the one stored in the master file. The master filename is relative to the `testdata` directory which is relative to the test. The test `t` fails if the given image is not equal to the loaded master image. In this case the given image is written into a file in `testdata/failed/<masterFilename>` (relative to the test). This path is also reported, thus the file can be used as new master.

func NewCheckedImage

func NewCheckedImage(w, h, hTiles, vTiles int) image.Image

NewCheckedImage returns a new black/white checked image with the specified size and the specified amount of horizontal and vertical tiles.
