Automation Testing or Test Automation is a technique to test software using special tools to execute a test case suite – a collection of test cases that test a software program and show that it displays certain behaviors. While humans perform Manual Testing, Automation Testing involves software tools performing each part of the test) instead. Automation testing softwares can also analyze and compare data and produce detailed test reports.
Application Testing is automation testing applied to software applications such as ERP (PeopleSoft, SAP, EVS, or any other custom homegrown applications) and CRM (Salesforce, Service Now, etc). This process involves using scripts, tools, or test automation frameworks to identify errors so that businesses can deliver bug-free and affective software applications to their consumers.
