If you are unable to use the percy:exec
command or prefer to run your tests using IDE run options, you can use the percy exec:start
and percy exec:stop
commands. To learn more, visit Run Percy.
This command starts Percy, create a new Percy build, takes snapshots and uploads them to your project, and stops Percy:
Congratulations!
You have successfully created your first build on Percy. To see the build with snapshots of your application, visit your project in Percy.
When you run another build with visual changes to your application, Percy takes new snapshots. You can then see the comparisons between the two runs on the new build.
