Being human beings, we’re likely to commit errors during any process. While some errors don’t have much impact on our lives, others are severe enough to break the entire system or software. In those severe situations, it’s important to have a software testing team that is able to catch errors well in advance, in times where we fail to pick them out.

Though we do try and keep an eye out for any mistakes, some might be able to pass through from blind spots and bad assumptions. In an ideal situation, you’d have someone else check through your work, in order toensure that all potential flaws get spotted.

For those that are new to software development, software testingmight seem like an insignificant task. However, you’ll be quick to realize that it’s actually an integral part of planning and development.

Before we can fully get into why it’s important, we should also talk about what software testing is.

What Is Software Testing?

Software Testing is the activity of checking whether theexpected results match the actual results. It helps to ensure that the software system is defect free. It helps to identify missing requirements, gaps, or errors that might be contrary to the requirements.

To help you further understand, imagine a banking system with a defect which causes Bank B to not receive the correct amount of money that is being transferred from Bank A.

It can also be situations where there are incorrect transfer fees applied to the transfer or the money is not converted into the right currency. Regardless of what it is, the issue is critical and can only have been avoided by proper software testing.

Types of Software Testing

There are four categories of software testing, which include functional testing, non-functional testing, change related type of testing and automated testing. Though there are over 150 types of testing, we’ll only be naming a few for the various categories of software testing.

  • Functional Testing – involves Graphical User Interface (GUI) testing, User Acceptance Tests (UAT), security and access control testing, interoperability testing and more.
  • Non-Functional Testing– involves performance testing, installation testing, usability testing, failover and recovery testing, configuration testing.
  • Change Related Type of Testing– involves smoke testing, regression testing, build verification test, sanity testing.
  • Automated Testing– based on programming ability. Quality Assurance specialist prepares automatic tests that are performed much faster than manual ones.

Critical Situations

There have been various events that have occurred through the years, which have cemented the belief that software testing is critical to the success of any business. We don’t just mean any sort of situations; we’re talking about situations, which could have been avoided if software development, as well as software testing had been performed properly and at the appropriate time.

  1. In 1996, a major U.S bank (First National Bank of Chicago) experienced a software bug, which caused 823 customers to be credited with $920 million USD.
  2. In 2015, Bloomberg’s terminal in London crashed because of a software glitch, which affected a surplus of 300,000 financial market traders. It forced a postpone of a £3bn GBP debt sale.
  3. Nissan faced a software failure in their airbag sensory detectors, which caused them to have to recall over one million vehicles from the market.
  4. Starbucks faced a software failure in their POS system, which caused them to close 60% of their stores in Canada and the U.S.

Why Is Software Testing Important?

After all that information, we can really get to why software testing really is important. Though you might already have an idea from the points we’ve made above, we’ll make a quick list of reasons as to why you need software testing.

  1. It is essential for ensuring the customers’ satisfaction and reliability in the application.
  2. It helps to pinpoint errors and defects right from the developmental phases.
  3. It enables the business to provide facilities to the customers, including high-quality software applications and products. This, in turn, helps to lower maintenance costs and provides more reliable, consistent, and accurate results.
  4. It helps to ensure the quality of the product, which then helps the customer to gain confidence in your organization.
  5. It avoids any future failures, which can also help the company to save money as repairing or maintaining can be more expensive towards the later development stages.
  6. It allows you to have a product or software application, which performs effectively.
  7. It simply is required in order for you to stay in business.

Software Testing Services

There are various software testing services which help you to reach the highest potential that software testing can give you. These services are great for giving you the confidence of ensuring that there are no errors in the code, resulting in a high-quality final product. You can perform in-house software testing or outsourcing it to professionals.

In-House Software Testing

Though in-house software testing has its fair share of advantages, the main one is the ability for business owners to control the whole process as well as being able to address the issues promptly.

Its main disadvantage is that it can be rather costly in comparison to outsourcing it. There are also additional hidden expenses. Including those associated with hiring people, training, and supporting a full team, even when they are not needed.

Outsource Software Testing

There are various companies, which offer independent software testing services, which give businesses the possibility of outsourcing their software testing. Outsourcing software testing can end up being the option that helps to reduce your costs.

It helps you to continue being focused on the core activity by allowing you to dedicate the majority of your time to customer services, marketing campaigns, and more. External testing offers you to have experienced, trained, and certified consultants around the clock.

Outsourcing testing is also great with flexibility as the team size can be adjusted according to the needs of each individual client. Smaller businesses tend to go towards outsourcing due to external testing companies having more adaptability, flexible businesses models, and reasonable prices.


And so, with all the information provided above, you’ll be able to clearly see how and why software testing is so important to any and all businesses. Just as testing electronic products, electronic appliances, and hardware products is important, software testing is just as, if not more so regardless of what industry your business is in.
