Software testing is a process that goes through several different phases to ensure that the software meets all requirements and is ready for release.

As the software industry grows exponentially, the need for efficiency will also grow at a similar pace. Organizations have adopted rapid software development models that quickly deliver working software at scale. For these rapid iterative models to succeed, it is crucial to have an effective and efficient safety net, i.e., testing. Therefore, software testing efficiency and effectiveness are also essential to delivering quality at scale.

Unit testing is essentially the process of isolating the smallest functional components of your code and making sure they’re working properly. It’s a critical part of the development process and, when implemented continually throughout development, helps to build a solid foundation for scalable applications.

Unit testing and integration testing are both key stages in the process of software development before release. The challenges that crop up when applying both protocols have seen DevOps question whether both testing methods are necessary.

Team sizes vary across organizations. For example, some companies have an in-house QA Team of 50 people (including QA Engineers, Automation Engineers, SDETs, etc.), while others have only a few testers. Some teams have no QA support at all. In addition to team size, release cycles are another variable to consider. Some companies release new updates or versions of their apps every week, while others have cycles ranging from one to three months.

Due to the evolution of the API-first companies like Stripe, Shopify, or Twilio, there has been a lot of attention to APIs in recent times. Thus implementing/adopting those APIs requires a disciplined skill set. It’s not just a single-day process; it’s a commitment toward it.
