What happens if your software is not tested? Before we actually begin with why software testing is important, let’s look at a few stats:
- 50% of app downloaders don’t return after day 1.
- In a survey, Forrester found out that just 29% of developers commit to exploratory testing.
- Every average app loses 95% of its users after just 3 months. Even the apps that fall into the top 10 category lose about 49% of their users in the same period.
Every entrepreneur knows that a software needs returning users to survive in the long run. Now the above stats convey one crucial thing that most software face & which make software testing even more important – the problem of users abandoning them.
Users quit using an app or any other piece of software for a variety of reasons – poor interface, difficult navigation, slow rendering/loading, etc. Having said that, 67% of consumers cite bad experiences as a reason for churn!
But whatever be the reason behind the user churn of your software, extensive software testing and QA can eliminate it to a large extent. So, let’s begin with why is software testing & QA Important for your business.
Why Is Software Testing & QA Important For Every Business?
Whenever I say Software Testing is important in this blog, I actually mean extensive testing and exploratory Quality Assurance of your software is necessary.
Let’s say that your development team creates a mobile app. In the testing phase, the app was tested on a few devices, say iPhone SE, and Google Nexus. A few bugs were found in the process and the team eliminated it. Now, you are all ready to launch your app. Or are you?
Testing your app on a few devices doesn’t even cover the basics Quality Assurance needed for a successful app. There are over 50 different types of software testing and all of them come with their own advantages & disadvantages.
Let’s look at a few software testing & QA for different industries.
- In the eCommerce industry, a few of the testing areas could be – product buyer flow, user registration, seller – product creation, shopping cart, and product search.
- Some of the types of software testing for game app testing are – multiplayer/network testing, realism testing, audio testing, etc.
- Similarly, for B2B apps, testing is usually done in stages – starting from the seed stage (Functional Testing, Dogfooding, etc.) to the IPO stage (Edge Cases, Penetration Testing, etc.)
No matter which industry you are planning to launch your software or app in, it is bound to fail without well-executed & exploratory software testing and Quality Assurance. And this is one of the primary reasons why software testing is important.
Now, it’s not feasible to test your software (mobile or web applications) using all the methods that exist. But, it is important to test your software using a few basic ones. Here are two major categories of software testing that most types of testing fall into.
Functional Testing is a type of Black Box testing where individual segments of your software are testing for their functionality against set parameters. It basically means that different parts of the software are tested to find out if they are doing exactly what they are supposed to do.
For instance, functional testing of software usually answers questions like:
- Is the login page working fine? Are you able to login using the credentials you used during registration? What’s the message being shown when a user enters the wrong credentials?
- When a new user registers on your software, is it reflected in your records?
- What happens when a user enters an incorrect card number while checking out?
Functional Software Testing is important because it helps you understand the functioning of your software from your users’ standpoint. A few types of functional testing are – Sanity Testing, Regression tests, Integration tests, and Beta/Usability testing.
Unlike Functional Testing, non-functional tests the performance of functions used to develop functionality in your software. Non-functional Testing of your software helps you get answers to questions like:
- Does your software behave the same way for different OSs?
- How does a function or the entire software work under extreme parameters?
- Does your software function when multiple users login simultaneously?
Given the critical nature of these questions, Non-Functional Software testing becomes equally important. A few testing methods used for Non-Function Testing are – Accessibility testing, Endurance testing, Maintainability testing, Scalability testing, etc.
Now that we know the basics of software testing & QA and why are they important for any business, let’s look at the biggest challenges that businesses face with them.
Note: Black Box Testing refers to the testing of the functionality of the software without worrying about its internal structure. On the other hand, White Box Testing is a method that tests the internal structures of software and not their functionalities.
Biggest Business & Technical Challenges of Software Testing
Software Testing is important but, like everything in your business, it also comes with a separate set of challenges.
Be it the huge cost of manual testing, percentage of error with automated testing, or anything else, there are many challenges businesses usually face with Software Testing & QA of your software.
In this blog on importance of software testing, let’s list out the biggest challenges of software testing & QA.
Lack of Proper Documentation – Increased Testing Costs
In a study published by the National Institute of Standards and Technology, it was found that the cost of software testing and fixing a bug in the maintenance phase increases by 880x as compared to the requirement gathering phase.
The team of testers testing an application should have a complete understanding of the software requirements right from the beginning. The lack of complete requirement gathering often leads to increased testing costs or inaccurate testing.
Trying to Reach Perfection
This is probably one of the biggest challenges of software testing & QA. If your AQ team aims to achieve 100% perfection and tries to fix every error in your software, it is completely impossible and can prove to be a complete waste of your business resources.
The same report by NIST (mentioned above) says that even a well-tested software has 2 – 7 errors per 1000 lines of code.
In the race of beating their competitors to market by launching their software first, businesses usually allow very limited time for testing & QA. This means that just the basics of testing are covered and the delivered software doesn’t perform well in the market.
Having said that, software testing is still necessary. Meeting delivery deadlines without compromising the quality of Software Testing & QA can be done by outsourcing. This will not only help you overcome this challenge but also will allow you to timely deliver your software.
The Sequence of Testing
The team of testers is often caught in the dilemma of which tests to execute first to get the best results. After following the initial standard sequence of testing methods, the team is caught between a plethora of software testing tools and methods which eventually delays the delivery of your new software.
Questions such as which part of QA should be done through Automation testing and which ones should be manually tested have been delaying the Software Testing timelines for a long.
Not Enough Regression Testing
During the course of software development, multiple changes are done on the go. It could be anything – skipping a step, adding new functionalities, changing how a screen or user flow works, etc.
If these changes are not validated using Regression Testing, they will end up disrupting and delaying QA and software testing in later stages. Besides, as mentioned earlier, this will also increase the overall cost of testing and QA.
What To Look For In Testing Tools For Your Software?
There are different types of testing methods but, instead of using all of them, your team uses the ones that are needed as per your software functionalities. Similarly, there are a plethora of different tools available out there.
So, what to look for in a testing tool for QA of your software? Here are a few things you must consider when choosing testing tools for your software.
Requirements of Your Software
It is important to list down the specifications and requirements of your software before testing it. Questions like – which development languages have you used, can help you here are.
The idea of doing this is to know the testing requirements of your software and to check if a tool complies with them.
Support for Test Automation
Be it tight time constraints around software testing or anything else, Test Automation has become a need of the hour. So, it definitely becomes one of the important criteria when choosing testing tools for your software.
While we are on this topic of importance of software testing & the tools to use, a software testing or QA tool that just supports the basics of test automation. Choose a tool that is capable of running your testing automation scripts, can automatically capture results, etc.
Flexibility and Ease of Use
A software testing tool is supposed to make the entire QA process easier and more efficient. So, it is important to check if a software testing tool you choose is flexible and easy to use.
This basically means that your testing & QA team should be able to easily adapt it for testing purposes.
Supported Platforms and Tagging
Make sure that a testing tool you choose supports all the platforms – iOS, Android, Web, etc. Such testing tools will save your team lots of resources – both time and money.
With a tool that supports testing for all the platforms, tagging becomes a mandatory feature. It basically allows your QA team to track and assign which test they want to run for your software on different platforms.
There are many other things you can consider to make sure you choose the right software tools. Look at the bug categories a tool offers along with license details and support costs it comes with.
