Business Applications Testing and the Software Testing Lifecycle

You’re probably well aware that developing quality business applications quickly isn’t an easy task. Successful software development is often a rigorous process, requiring businesses to work through several phases of the software development lifecycle (SDLC) to ensure that customers receive the best product possible.

Testing occurs throughout this lifecycle. During testing, test engineers, quality-assurance (QA) analysts, and developers evaluate the software to determine whether it’s meeting requirements and functioning as expected. The goal is for testers to identify any differences between expected and actual outcomes. Analyzing and fixing issues, or “bugs,” before deployment saves time (and money) and provides customers with a high-quality, reliable, and secure product.

While QA teams often are tasked with testing business applications, the reality is that quality is everyone’s responsibility. Learn how team members can contribute to the testing process and use testing insights.

Testing plays such an important role in the SDLC that it has its own lifecycle—the software testing lifecycle (STLC)—which has six stages.

By working through the STLC and its clearly defined stages and requirements, businesses help set their software up for success. It’s important to remember, however, that testing isn’t a one-and-done type of thing. Businesses should approach it as a continuous process that helps them consistently improve quality, reliability, security, and performance. Let’s explore a few more reasons testing is so important.

Why It’s Best to Test

The reality is that today’s customer is expecting a seamless experience when using business applications. Providing anything less than that by failing to test can have serious business repercussions. Software defects result in costly downtime and frustrated users who can’t access products or services. These types of disruptions are detrimental. They bring business operations to a halt, damage reputations, and cause significant financial losses.

According to Copado’s 2022 State of Salesforce Testing Report, 92% of Salesforce professionals surveyed face critical production issues due to inadequate testing. What’s more, a lack of testing was identified as the #1 risk to digital transformations.

Thorough testing serves as a safeguard against these high-stakes risks by allowing businesses to:

• Identify vulnerabilities and mitigate risk by preventing costly errors and heading off data breaches and system failures.
  
• Avoid fines and penalties by complying with regulatory requirements and industry standards.
  
• Improve, innovate, and evolve continually by using valuable testing feedback.
  
• Increase release efficiency by fixing issues early in the development lifecycle.
  

The value of testing is undeniable. It helps businesses ensure that their software meets the highest quality and performance standards, and customer (and business) expectations. But just as businesses shouldn’t take a one-and-done approach to testing, they shouldn’t take a one-size-fits-all approach either. Testing effectively requires testers—typically quality-assurance (QA) testers—to analyze business needs and product requirements and select the appropriate testing methods, types, and models.

Testing Methods, Types, and Models

Here’s an overview of a few commonly used business-application testing types, methods, and models.

Testing Methods

There are two primary methods of testing: manual and automated.

Manual testing tests software’s functionality without using automated tools. Because manual testers approach testing from a human perspective, they can better predict end-user behavior. Also, manual testing provides for more creativity and flexibility in the interpretation of use cases.

Automated testing conducts testing processes using automated tools and techniques. It doesn’t make the testing process automatic. Rather, it supports manual testers by taking over tasks that don’t require human judgment. Automated testing increases accuracy by eliminating human error and efficiency through its use of repeatable test cases.

Testing Types

Testing teams use various functional and nonfunctional testing types depending on project needs and technical requirements.

Testing Models

Testing models typically align with development methodologies. Here’s a quick breakdown.

• Classic (or Waterfall): The processes of development and testing cascade so that the output for one stage becomes the input of another in a linear or sequential fashion.
  
• Shift-Left: This model addresses quality issues “at the root” by including testing activities early in the development lifecycle.
  
• Shift-Right: In this model, testing is conducted in production to gather insights from user feedback and interactions.
  
• Agile: This incremental and flexible approach to testing ensures quality by requiring shorter development cycles (also known as sprints) and close collaboration between teams.
  

Lots of businesses are using the agile model and automated testing to keep up with customers and their needs. Implementing both effectively, however, requires a clearly defined agile testing-automation strategy.

Agile + Automation = A Strategy for Success

A successful agile testing-automation strategy carefully considers people, processes, and technology, and it outlines the approach and principles that guides the testing. In addition to embedding tools into development that support test automation, tracking, and management, this type of strategy typically includes:

• Test planning for each sprint that involves defining the scope of the sprint’s user stories and determining which testing methods and tools testers will use.
  
• Test and use-case development based on user stories and acceptance criteria, which evolves as software features are added or modified.
  
• Test execution—including integration testing—that occurs both concurrently with development and in iterative cycles.
  

In addition, an agile testing-automation strategy:

• Aligns closely with business goals and desired project outcomes.
  
• Clearly defines roles and responsibilities for all members of the testing team.
  
• Provides scalability and flexibility to accommodate projects of different sizes and complexity.
  
• Fosters continuous improvement based on feedback, insights, and outcomes from each testing cycle.
  

Now that you know what an agile testing-automation strategy is and how to make it successful, you might be wondering why it’s so important to have. The short answer is that having an agile testing-automation strategy supports the efficient development and release of high-quality, reliable software. But if we dig a little deeper, we see that automated testing specifically has the following benefits in the agile environment.

• Reduced testing time
  
• Reduced costs
  
• Increased test coverage
  
• Improved resource optimization
  
• Improved accuracy
  
• Enhanced team morale
  
• Faster feedback
  
• Accelerated scalability
  

For businesses, implementing automated testing provides a significant return on investment (ROI). If we want to crunch the numbers, we use the following formula.

• Benefits: Direct savings from a reduction in manual testing hours, decreased time to market, and ‌avoidance of defect costs
  
• Costs: Initial setup for automation tools, training, and maintenance—and ongoing licensing and update expenses
  

For example, suppose an organization spends $100,000 on implementing an agile testing-automation strategy. As a result, it saves $300,000 by shortening testing time, increasing release speed, and reducing post-release defects.

Using the formula, we calculate a 200% ROI, which indicates that the organization has doubled its initial investment in implementing the agile-testing strategy!

There’s no doubt that testing software—especially by implementing an agile testing-automation strategy—has tremendous value for businesses.
