The Ultimate Guide to Performance
Testing in Low-Code, No-Code
Environments
The emergence of Low-Code and No-Code platforms has reshaped the realm of software
development. These platforms offer a transformative solution, empowering individuals with
varying coding proficiencies to craft functional and efficient applications. Through intuitive visual
development tools and pre-built components, Low-Code/No-Code platforms facilitate
problem-solving and value creation, liberating users from the complexities of traditional coding.
However, amidst the accessibility they provide, a critical concern arises: can applications
developed on these platforms deliver performance on par with traditionally coded ones? This
question underscores the significance of Low-Code/No-Code performance testing, which has
become pivotal for organizations contemplating this innovative approach. By addressing
performance challenges head-on, organizations can confidently harness the potential of
Low-Code/No-Code platforms while ensuring seamless functionality and efficiency in their
software endeavors.
Exploring the Essence of Low-Code/No-Code Platforms

Low-code/No-Code (LCNC) tools signify a paradigm shift in software development, streamlining
the creation of applications by minimizing manual coding and fostering accessibility for all.
These innovative platforms leverage the power of visual programming, allowing for swift
application development and deployment akin to assembling Lego blocks to construct a model.
Notably, platforms like OutSystems exemplify this approach, offering comprehensive tools for
application design, integration, and customization without the need for extensive coding.
Similarly, Adalo, a prominent no-code platform, empowers users to create feature-rich
applications effortlessly, catering to the needs of entrepreneurs and small businesses seeking
digital transformation.
As the significance of testing in software development cannot be overstated, LCNC platforms
revolutionize this aspect by democratizing and accelerating the testing process. Through
intuitive visual interfaces and automated workflows, non-technical users can design, implement,
and maintain test cases efficiently, ensuring product quality and functionality without the
intricacies of conventional testing methods.
Advantages of Low-Code and No-Code Platforms
● Accelerate application development and delivery.
● Empower non-IT professionals to create tailored business applications.
● Liberate professional developers from routine programming tasks.
● Enable development teams to focus on strategic initiatives for value creation.
Navigating the Challenges of Low-Code and No-Code
Platforms
● Loss of visibility and oversight: Due to the low-cost and user-friendly nature of these
platforms, organizational leaders may lose track of app development, leading to potential
data misuse or exposure, and the proliferation of shadow IT.
● Management and scalability issues: Organizations may face difficulties in managing,
maintaining, and scaling apps developed through these platforms, often accompanied by
increased infrastructure and storage costs due to heightened development activity.
● Task suitability concerns: Some tasks may not be well-suited for low-code and
no-code methods, leading to inefficient resource utilization and potential waste. It's
crucial for organizations to carefully assess project suitability to maximize efficiency in
app development endeavors.
The Importance of Performance in Every Environment
Performance is a critical aspect across all application environments, impacting various key
areas:

● User Experience (UX): Regardless of the platform used, user satisfaction is paramount.
Slow apps can lead to decreased engagement and satisfaction, with studies showing
high abandonment rates for sluggish applications.
● Operational Efficiency: Inefficient applications can hinder productivity within
organizations, causing employees to waste valuable time waiting for tasks to be
completed.
● Scalability: While an app may perform well in small-scale testing, ensuring seamless
operation at scale is crucial. Performance testing helps businesses avoid scalability
issues that could disrupt service when the application is rolled out to a larger user base.
● Reputation & Revenue: Poorly performing apps can damage a company's reputation
and lead to loss of revenue. Customers are less likely to engage with a business if they
cannot rely on its app to function efficiently.
Performance Objectives for Low-Code/No-Code Platforms
In the realm of Low-Code/No-Code platforms, attaining optimal performance necessitates a
well-defined roadmap. Establishing specific and measurable performance objectives serves as
the cornerstone for successful application development. These objectives not only guide the
development process but also provide benchmarks to evaluate the application's efficiency. Key
performance goals include:
● Achieving a Specific Response Time: Defining maximum acceptable response times
for various user interactions within the application to ensure optimal user experience.
● Supporting a Defined User Load: Determining the maximum number of users the
application can support concurrently to maintain consistent performance during peak
usage.
● Maintaining Consistent Throughput: Establishing desired throughput levels under
different usage scenarios to gauge the application's efficiency and scalability.
● Ensuring Scalability: Addressing the application's ability to handle increased workloads
and user loads without compromising performance, is crucial for accommodating growth
while preserving user experience integrity.
Browser-Driven Performance Testing: Ensuring Accurate
End-User Experience
Protocol-based performance testing primarily focuses on server and network-level performance,
often overlooking browser rendering times for HTML and JavaScript. In contrast, browser-driven
performance testing captures these crucial rendering times, providing a more precise
representation of the end-user experience. By incorporating HTML, JavaScript, and CSS timing
into test results, browser-based testing offers a more accurate assessment of application
performance.
Efficiency and Resource Considerations:

● Browser-based performance testing requires more resources due to the intensive nature
of browser instances.
● Despite higher infrastructure costs, this approach reduces scripting efforts and time
duration compared to protocol-based testing.
● The streamlined scripting process and faster execution contribute to overall
cost-effectiveness.
● Cloud infrastructure readily provides the necessary resources for browser-based testing,
aligning with the objective of accelerated release cycles without compromising end-user
experience.
Tips & Techniques for Performance Testing of
Low-Code/No-Code Applications
