Method testFormat

integration_test/matrix_test.go:83–131

testFormat fetches images iterates over images in the specified folder, runs imgproxy on each image, and compares the result with the reference image which is expected to be in the `integration` folder with the same name but with `.png` extension.

(source, target imagetype.Type)
