Why Should You Test Your Application All the Time?

Nowadays, each software application needs to deliver seamless user experience across multiple devices, platforms and browsers to stay popular and profitable. But the performance and user experience of the software is impacted by a number of external factors including systems, processes and infrastructures. No business can exercise control over these external factors affecting its software’s user interface (UI) and user experience (UX). That is why; it becomes essential for businesses to test their software repeatedly and continuously to maintain its quality and user experience.

5 Reasons Why Software Applications Must Be Tested Continuously

1) Shorter Delivery Cycles

A steady increase is being noted in the number of organizations adopting agile project management methodology. The agile methodology emphasizes on short and incremental software delivery cycles. The methodology further requires programmers and testers to work together and concurrently. Once a particular functionality or module of the software is developed, the testers need to assess its quality and share the test results with various stakeholders in the project. The shorter delivery cycles have made it essential for businesses to perform continuous testing.

2) Early Detections of Defects and Bugs

Many studies have highlighted a business can reduce software testing time and cost drastically through continuous testing. When the defects or bugs in an application are detected early, it becomes easier for programmers to get them fixed. As the code is still fresh in their mind, the programmers can work on the defects without putting extra time and effort. Thus, a business can switch from waterfall testing to continuous testing to reduce the defect turnaround time significantly.

3) Overcome Time and Resource Constraints

Most businesses explore ways to enhance test coverage by overcoming constraints related to resources and time. When the software testing commences after the development phase of the project, the testers have to perform the required tests within a stipulated amount of time without affecting the software’s time to market. But when the testers perform continuous testing, it becomes easier for them to complete all tests without requiring any additional time. Hence, continuous testing helps businesses to deliver a flawless software application despite the constraints related to time and resources.

4) Produce High Quality Code

Many enterprises nowadays review source code of software applications to make it safe and secure. The testing model requires the source code of the software to be assessed and reviewed frequently and thoroughly. While reviewing the source code, the testers can identify the pieces of code that may make the application vulnerable to security attacks. A business can always produce high quality code by performing continuous testing. When software is tested continuously, it becomes easier for testers to each and everything in a build. They can even review the source code of the software repeatedly to ensure that the software is not vulnerable to evolving security threats.

5) Essential for Mobile Apps

Nowadays most businesses develop mobile apps by targeting multiple devices and platforms. So they need to ensure that the app deliver quality user experience across many devices and platforms. Likewise, they need to check the application’s user interface across different models of smartphones, tablets and phablets. With mobile operating systems being updated at regular intervals and new mobile apps emerging on a regular basis, it has become essential for businesses to check the mobile app’s performance and user experience continuously. So the businesses must test the mobile apps continuously to accomplish more downloads and higher returns.

Each enterprise can facilitate continuous software testing in a number of ways. It can always provide testers with test automation tools to perform the tests repeatedly and continuously without putting extra time and effort. Likewise, it can adopt continuous integration (CI) methodology to enable the testers to perform the tests accurately and frequently. 

Why Should Organizations Go Agile in Their Testing Approach

The agile project management methodology emphasizes on software applications being developed and tested in rapid and incremental cycles. The model does not consider software development and software testing as two distinct processes. In an agile environment, the programmers and testers have to work together to ensure that the software quality is maintained. The collaboration promotes continuous iteration of development and testing throughout the entire software development life cycle (SDLC).  Each business can reap a number of benefits by adopting the agile software testing model.

Understanding Important Benefits of Agile Testing Methodology

Instantaneous Feedback

In an agile environment, programmers and testers work as a single team. So the entire team is responsible for software quality. The testers can write unit tests each time a new feature or functionality is added to the application, and test the new code almost immediately. Further, they can provide instant feedback to the programmers about defects or bugs in the software. Based on the feedback received from the testers, the programmers can fix the bugs in the same build.

Better and Continuous Communication

In an agile environment, testers have to stay connected with programmers, project managers, customers and other stakeholders in the project. The emphasis on people and interaction results in better and effective communication. The programmers can simply contact the testers to gather more specific and detailed information about the bugs identified by them.  The daily scrum sessions further help the entire team to focus on identifying and fixing important issues in advance.

Easy to Eliminate Major Defects

It becomes easier for programmers to fix the bugs when the defects in the application are identified immediate after the coding phase. As the code it still fresh in the programmer’s mind, he can get the defects fixed without putting any extra time and effort. The instant feedback provided by testers help developers to work on major bugs in the application almost immediately. The business can further avoid additional cost when the bugs are identified during the coding phase.

Easy to Reproduce Bugs

While preparing a bug report, testers have to write detailed and specific information about the bugs identified in the software. They can further reduce the defect turnaround time drastically by reproducing the bugs. But testers have to put additional time and effort to reproduce the bugs. In an agile environment, they test the software once the code is written. So they find time to write detailed bug reports and reproduce the defects accurately. 

Easy to Incorporate Changes

To reap benefits of waterfall software testing, a business has to define the business requirements from the beginning of the project. But software developers nowadays have to build applications based on frequently-changing business requirements. So it becomes impossible for the managers to outline the business requirements clearly before the project starts. But a business can always adopt agile testing methodology to incorporate changes and enhancements required by the client. In an agile environment, applications are developed and tested in short sprints. So the programmer and testers have to focus only on a single sprint with specific features. They can easily accommodate the new business requirements in the next sprint without any hassle.

Enhanced Test Coverage

Often developers have to test software thoroughly without increasing its time to delivery. So they have to prioritize the defects at the time of preparing bug reports. But agile methodology enables testers to perform tests continuously throughout the software development life cycle. Many enterprises even invest in test automation tools to enable testers to repeat the tests under various conditions. Thus, the testers can assess all aspects of the software without affecting the delivery time.

Shorter Delivery Period

Each business has to deliver software continuously and rapidly to make the client happy. Hence, businesses frequently explore ways to shorten the delivery period. Agile methodology emphasize on development and testing of the application in small iterations. So it becomes easier for enterprises to deliver the working software to the client at frequent intervals.  The constant interaction between the testers and customers further resolve various issues and differences without any delay.

However, it is also important for the organization to keep in mind some of the important shortcomings of agile testing model. Likewise, the managers also need to understand when to use the agile testing methodology. But each enterprise can reap benefits in terms of time, quality and cost by implementing a custom agile testing strategy.
