Automated testing expanded with Agile principles because testing in a repeatable manner that is secure, reliable, and keeps pace with the rapid deployment of software is required for this environment. In their book Agile Testing: A Practical Guide for Testers and Agile Teams, authors Lisa Crispin and Janet Gregory claim Agile development depends on test automation to succeed. They emphasize the team effort required for test automation and recommend automating tests early in the development process. Also, the development of automation code is as important as the development of the actual production code for software. The “test-first" approach to development is known as Test-Driven Development.
Tosca Testsuite by Tricentis makes use of model-based test automation to automate software testing. This tool helps in planning and designing test case. It is a test data provisioning tool and helps in testing mobile apps. It has integration management and services virtualization network. Even risk coverage is there for the same. Tosca Testsuite has market leading technology which helps in achieving sustainable automation. It also helps in reducing the regression of testing from weeks to minutes.
I think we can all agree that automation is a critical part of any organization's software delivery pipeline, especially if you call yourself "agile." It's pretty intuitive that if you automate testing, your release cycles are going to get shorter. "So, if that's the case," you might say, "why don't we just automate everything?" There's a good reason: automation comes with a price.
