Introduction
We live in a world of software. It governs all of our industries and runs our very lives. From complex enterprise-grade solutions to simple applications, including tools like a how many pages calculator, not a day goes by when we are not dependent on software. But behind every solution is a complex development lifecycle that ends with testing. This is the crucial stage where teams ascertain if the software works as intended. Depending on the type, this process can be rigorous and time-consuming. That is where automated software testing comes into play.
If you are the manager of a team of testers, a project manager overseeing the development, or even the CEO of a company, this comprehensive guide will give you insight into why automated testing could be the game-changer your business needs.
Automated Software Testing: An Overview
Automated Software Testing is a process that uses software tools to run predefined tests on a software application. Unlike manual testing, where a human tester interacts with the software, automated testing uses scripts and tools to execute tests and then compares the actual results with expected outcomes. Needless to point out, this process is automated, which means that tests are run much faster and with nearly 100% accuracy.
As is the case with any kind of workflow, automation accelerates the process of testing, which reduces the time for development. A high rate of accuracy coupled with shorter development lifecycles is a big win, especially for small, budding startups. The process of automated software testing usually involves unit testing, functionality testing, load testing, performance testing, and more.
Types of Software Testing
Whether it is automated or manual, software testing has two main types:
1. Functional Testing
This type of testing is concerned with verifying whether the software functions as designed. It includes testing the user interface, APIs, database, security, client/server applications, and functionality of the application modules. This test determines if the app works as intended for the users.
2. Non-Functional Testing
This type of testing focuses on aspects of the app that are not related to particular user interactions. These mainly include performance testing, load testing, stress testing, accessibility testing, and more.
Why Should Companies Implement Automated Testing?
Using solutions for automated software testing brings numerous benefits to companies of all sizes. Let’s have a closer look at some of them:
- Speed
This is the most obvious advantage that automation brings. It can carry out tests much faster with little to no human intervention needed. As a result, a team of testers can execute a broader range of tests to speed up the overall testing workflow. A major advantage of automated software testing is the ability to run tests 24/7, which is particularly beneficial for businesses operating across multiple time zones.
- Accuracy
Automating any process removes or minimizes the need for human intervention. As a result, there will be fewer chances for errors or inconsistencies. It is basic human nature to make mistakes, especially when performing repetitive tasks continuously. By removing the human factor, automation maximizes the accuracy to nearly 100%.
- Cost-Efficiency
Although it will require an initial investment to purchase and set up an automated software testing system, the payoff is definitely worth it. The first and most visible benefit is the reduction in time needed for testing. This enables testing teams to catch bugs early in the development process, saving time and money in the long run.
- Faster Time to Market
Software products need to be thoroughly tested against various parameters before being deployed. By accelerating the testing process, automation can significantly reduce the time it takes to get a product to market. By rapidly executing tests and providing immediate feedback, development teams can fix bugs and make improvements faster. This goes on to speed up the overall software development lifecycle and lower its time to market.
- Improved Compliance
In addition to ensuring that software works as intended, testing is also carried out to ascertain if it complies with regulations. Depending on the type and functionality, every software is bound by regulations, and failure to comply with them can result in severe consequences ranging from fines to jail time. Implementing automated software testing ensures that compliance testing is done accurately and comprehensively.
Things to Consider When Implementing Automated Software Testing
Adopting software testing into existing development workflows requires planning and depends on some factors. Let’s find out what they are:
- Testing Tools
There is a wide array of automated software testing tools, each with its own set of strengths and weaknesses. Additionally, not all tools can be applicable for testing all kinds of software effectively. So, it is important to consider your company’s needs, the available budget, and the experience of your testing teams.
- Prioritize What to Automate
While it is true that automation will boost the speed of testing and maximize accuracy, not everything can and should be automated. Tasks that are repetitive, prone to human error, or require multiple data sets are prime candidates for automation. On the other hand, any activity that requires conscious decision-making is better left for manual testing. It helps if a seasoned project manager and experienced tester are present for decision-making. Their insight will be invaluable when planning automation.
- Training
Investing in automated software testing tools is definitely worthwhile. However, it is also necessary to train your team of testers in using the solution. Training lets the testers leverage the full potential of automated testing.
- Continuous Evaluation
While automation testing software does conduct tests on its own, it is not a “set and forget” solution. It is important for companies to evaluate their tests’ effectiveness and adjust as necessary. The goal of automation is to improve quality and efficiency, not just to automate for automation's sake.
Conclusion
The software development industry is highly competitive and cutthroat. In light of this, implementing automated software testing is not a luxury, but a matter of staying competitive. By delivering speed, accuracy, and cost savings, it enables businesses to produce high-quality software that meets the evolving demands of customers. For companies aiming for quality and efficiency, automated software testing is an absolute must-have.
As more and more automated tools continue to roll out, automated testing will play an increasing role in the development lifecycle. It will enable startups and medium-sized companies to stay ahead of the curve and deliver top-notch solutions.
