“While using and teaching Agile practices like test-driven development (TDD) on projects in different environments, I kept coming across the same confusion and misunderstandings. Programmers wanted to know where to start, what to test and what not to test, how much to test in one go, what to call their tests, and how to understand why a test fails. [….] My response is BDD.”
Unless you're a brick-and mortar retail operation that collects money due immediately, you probably need to create invoices for customers. There are still businesses that complete this task using a word processor, but they then must have a separate method for tracking invoices sent. There are more integrated, effective ways to do that if the only accounting chore you want to do on your computer is to send invoices to customers. Zoho Invoice is one such cloud-based application, as are Hiveage and Invoicera. All three provide tools for creating and sending invoices, but they also help you receive and track payments.

Being originated in the 2000s and evolved over a decade, Selenium has been an automation framework of choice for Web automation testers, especially for those who possess advanced programming and scripting skills. Selenium has become a core framework for other open-source test automation tools such as Katalon Studio, Watir, Protractor, and Robot Framework.
