v1.0

This is a meta issue for tracking v1.0 issues.

  • Add reporter option rather than having separate test and gallery commands
  • Add selectors option that takes screenshots of individual elements instead of the whole page
  • Improve gallery output (#15)
  • Exit with code >0 on failure (#18)
  • Improve error messages (#27)

Add --verbose flag

Show messages like:

  • Taking capture of http://... at Npx
  • Comparing captures of http://... and http:// at Npx
  • Generating gallery for N results
  • Gallery generated to /path/to/index.html

Trim whitespace from bottom of images

This can be done with something like:

  convert in.png \
          -background white -splice 0x1 -background black -splice 0x1 \
          -trim +repage -chop 0x1 out.png

Assuming that -gravity defaults to North-West

Improve error messages

There are a few cases where Whoopsie blows up and gives some unhelpful error messages:

  • PhantomJS errors when loading the page or taking the screenshot
  • ImageMagick errors while running compare
  • ImageMagick not installed

Most of these should be caught and shown as warnings rather than being fatal errors.

Improve gallery output

  • Summary table at the top (matrix of all tests)
  • Clip (overflow: hidden; max-height: Npx) images, with an "expand" button to show the full images for each test.
  • Filters
    • Width
    • Difference
