Using TestZeus and Applitools to Test Salesforce Apps
This repo has a short example of how to test a Salesforce app with TestZeus and Applitools.
Development
It's recommended that you use an IDE like Intellij IDEA since it has support for Maven (build systems), Java (programming language) and JUnit (testing framework).
Deployment
Assuming you are using an IDE, you can either run AccountsTest.java for a basic TestZeus test, or AccountsApplitoolsTest.java
for an example of TestZeus used with Applitools.
