How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

With the exponential growth of the mobile app market, ensuring the quality and reliability of
these applications has become paramount. This is where mobile app testing plays a crucial
role. Mobile app testing encompasses a range of activities and processes designed to evaluate
the functionality, performance, usability, compatibility, and security of mobile applications
across various devices, platforms, and network conditions. In essence, it is the systematic
examination of mobile apps to identify and mitigate any defects or issues that could
compromise user experience or pose risks to users' data and privacy.
The importance of mobile app testing cannot be overstated. In a highly competitive app
landscape, users have high expectations for quality, reliability, and performance. A single
glitch or bug can lead to negative reviews, uninstallations, and damage to the reputation of
the app and its developers. Therefore, thorough testing is essential to ensure that mobile apps
meet the expectations and demands of users, ultimately leading to increased user satisfaction,
engagement, and retention.
Mobile app testing involves various types of testing, each serving a specific purpose in
evaluating different aspects of an application. Functional testing focuses on ensuring that the
app performs its intended functions correctly, while performance testing assesses how the app
behaves under various conditions such as heavy load, low network bandwidth, or high CPU
usage. Usability testing evaluates the app's user interface and overall user experience, while
compatibility testing ensures that the app works seamlessly across different devices,
operating systems, and screen sizes. Additionally, security testing is critical to identify and
address vulnerabilities that could be exploited by malicious actors to compromise the app's
integrity and users' data.
With the rapid evolution of mobile technology, testing approaches and methodologies have

2 Types of Mobile App Testing
Mobile app testing is a multifaceted process that involves various types of testing to ensure
the quality and reliability of mobile applications. Each type of testing serves a specific
purpose in evaluating different aspects of an app's functionality, performance, usability,
compatibility, and security. In this chapter, we will explore the different types of mobile app
testing in detail.
Functional Testing:
Functional testing is essentially about ensuring that every feature and function of the app
works as intended. It's like checking off items on a list to make sure they're all there and
functioning properly. This type of testing involves examining the app's behavior under
different scenarios to verify that it responds correctly to user inputs and produces the
expected outputs.
• Unit Testing: This is the most granular level of testing, where individual components
or modules of the app are tested in isolation. For example, if you have a calculator
app, unit testing would involve testing each mathematical operation (addition,
subtraction, multiplication, division) to ensure they produce the correct results.
• Integration Testing: Integration testing focuses on testing how different components
or modules of the app interact with each other. In the case of the calculator app,
integration testing would involve testing the interaction between the user interface and
the underlying calculation logic to ensure they work together seamlessly.
• System Testing: System testing involves testing the app as a whole to ensure that all
components and modules function correctly when integrated. This is where you test
the app in its entirety to make sure it meets the specified requirements and behaves as
expected.
Performance Testing:
Performance testing is all about evaluating how well the app performs under various
conditions. It's like stress-testing a car to see how fast it can go and how well it handles
different road conditions. Performance testing helps identify any bottlenecks or performance
issues that could affect the app's responsiveness and user experience.
• Load Testing: Load testing involves testing the app's performance under normal and
peak load conditions to ensure it can handle the expected number of users without
slowing down or crashing. For example, if you have a messaging app, load testing
5. would involve simulating a large number of users sending messages simultaneously to
see how the app handles the load.
• Stress Testing: Stress testing pushes the app to its limits to see how it behaves under
extreme load conditions. This is where you really test the app's resilience and stability
by subjecting it to a higher load than it's designed to handle. For example, stress
testing a navigation app would involve simulating a large number of users requesting
directions simultaneously to see if the app can keep up.
• Stability Testing: Stability testing involves testing the app's stability over an
extended period to ensure it remains reliable and functional without crashing or
freezing. This is where you test the app's endurance by running it for long periods
under normal conditions to see if it remains stable over time.
Usability Testing:
Usability testing focuses on evaluating the app's user interface (UI) and overall user
experience (UX) to ensure it is intuitive, easy to use, and meets the needs of its target
audience. It's like asking someone to test drive a car and provide feedback on how
comfortable it is to drive and how easy it is to use the controls.
• Observation: This involves observing real users as they interact with the app to
identify any usability issues or pain points. For example, if you have a shopping app,
you might observe users as they browse products, add items to their cart, and check
out to see if they encounter any difficulties.
• Interviews: This involves interviewing users to gather feedback on their experience
with the app. For example, you might ask users what they liked and didn't like about
the app, what features they found useful or confusing, and any suggestions they have
for improvement.
• Surveys: This involves collecting feedback from users through surveys to gather
quantitative data on their satisfaction with the app. For example, you might ask users
to rate the app on various usability metrics such as ease of use, learnability, and
efficiency.
4. Compatibility Testing:
Compatibility testing is crucial for ensuring that the app works seamlessly across different
devices, operating systems, screen sizes, and configurations. It's like making sure a piece of
furniture fits through a doorway and looks good in any room of the house.
• Device Compatibility: This involves testing the app on a range of devices
(smartphones, tablets, wearables) to ensure it works correctly on each device. For
example, you might test the app on different models of iPhones and Android phones
to ensure it looks good and performs well on each device.
• Operating System Compatibility: This involves testing the app on different versions
of the operating system (iOS, Android) to ensure it works correctly on each version.
For example, you might test the app on different versions of iOS (iOS 10, iOS 11, iOS
12) to ensure it is compatible with each version.
• Screen Size Compatibility: This involves testing the app on devices with different
screen sizes and resolutions to ensure it looks good and functions properly on each
screen size. For example, you might test the app on devices with small screens (e.g.,
iPhone SE) and large screens (e.g., iPad Pro) to ensure it adapts to each screen size.
6. Security Testing:
Security testing is critical for identifying and addressing vulnerabilities that could be
exploited by malicious actors to compromise the app's integrity and users' data. It's like
putting a lock on the door to prevent unauthorized access and protect valuables inside.
• Data Encryption: This involves testing the app's encryption methods to ensure
sensitive data (such as user credentials, payment information) is protected from
unauthorized access. For example, you might test the app's encryption algorithms
(AES, RSA) to ensure they are secure and robust.
• Authentication and Authorization: This involves testing the app's login and
authentication mechanisms to ensure they are secure and resistant to unauthorized
access. For example, you might test the app's password strength requirements and
multi-factor authentication (MFA) to ensure they provide adequate protection against
unauthorized access.
• Network Security: This involves testing the app's communication channels to ensure
data transmitted over the network is encrypted and protected from interception. For
example, you might test the app's use of secure communication protocols (HTTPS,
SSL/TLS) to ensure data transmitted between the app and server is secure and cannot
be intercepted by attackers.
In conclusion, mobile app testing is a multifaceted process that involves various types of
testing to ensure the quality, reliability, and security of mobile applications. By employing a
comprehensive testing strategy that includes functional testing, performance testing, usability
testing, compatibility testing, and security testing, app developers can deliver high-quality

like environments and tested in real-world conditions, enabling rapid and reliable
releases.
• Infrastructure as Code (IaC): DevOps testing treats infrastructure as code, where
infrastructure configurations are defined and managed using code, enabling
consistent, repeatable, and automated provisioning of environments for testing and
deployment.
• Shift-Left Testing: DevOps testing encourages shifting testing activities leftward in
the development lifecycle, with testing activities starting earlier in the process and
being integrated into development and operations workflows.
In conclusion, testing approaches and methodologies such as manual testing, automated
testing, agile testing, and DevOps testing play a crucial role in ensuring the quality,
reliability, and success of mobile applications. By adopting a holistic approach to testing that
combines the strengths of each approach and adapts to the needs of the project and team,
