If you pay close attention, you’ll notice that toggle switches are all around us because lots of things have two simple states: either ON or OFF (in binary 1 or 0).
Collecting and examining data from multiple sources can be a tedious process. The digital world is constantly evolving. To stay competitive in this fast-paced environment, businesses must frequently test their products and services. While it’s easy to collect raw data from multiple sources, it’s far more complex to interpret it properly.
Automating testing is a crucial step in the development pipeline of a software product. In an agile development environment, where there is continuous development, deployment, and maintenance of software products, automation testing ensures that the end software products delivered are error-free.
One of the most important tasks of a software developer is not just writing code fast; it is the ability to find what causes errors and bugs whenever you encounter one and the ability to solve them quickly.
