The mobile app testing world has gone through a paradigm shift in which Quality Assurance is gradually becoming Quality Engineering, and testing is shifting to the left with the application of modern testing principles. This evolution has made it necessary for organizations to adapt to new trends and keep up with the times. Seamless end-user experience, Performance, Usability, and UX have become the top priority for all global mobile app companies, as it directly affects retention rates, conversions, and ultimately revenue. When customer satisfaction can directly impact your app store ratings and ultimately your revenue, how do you ensure that you can deliver the best possible digital experiences to your users every time? Even if we deliver a brilliant feature, if it's not user-friendly, people will eventually stop using those apps, leading to a low rating on the app/play store. As high-performing apps are user favorites, testers and app developers should also adopt quality-centric strategies while implementing mobile apps. In this talk, we will discuss how to align our testing strategies based on my personal experience working in a fast-paced fintech startup to build successful mobile apps. 4 key takeaways from this session: 1. How to deliver top-ranking Android and iOS apps and ensure you can keep those 5-star ratings rolling! 2.Shifting left phase of Mobile App testing(Modern testing principles applied) 3.Mobile App Testing Heuristics & Important metrics 4. Scalable & Sustainable test automation, Test insights and Analytics for prediction

36. ModernTesting Principles applied:
Our priority is improving the business. ● Our main mission is not to find bugs or code/functionality correctness.
● Understanding the customer and what solution we are providing for them.
We accelerate the team, and use models
like LeanThinking and theTheory of
Constraints to help identify, prioritize
and mitigate bottlenecks from the
system.
● Continuous improvement and learning.
● Creating capacity to do more.
● Improving the flow of productive activities.
● Taking a whole system perspective.
● Empowering and engaging with people.
● Understanding customer/stakeholder values and demands.
We are a force for continuous
improvement, helping the team adapt
and optimize in order to succeed, rather
than providing a safety net to catch
failures.
● Collaboration between team members.
● Share knowledge and adapt to new changes.
● Learn from mistakes & Fail Faster.
We care deeply about the quality
culture of our team, and we coach, lead,
and nurture the team towards a more
mature quality culture.
● Quality culture, a shared responsibility.
● Sharing your learning, and learn from each other.
● Discussion and improvement over culture of blaming.

37. ModernTesting Principles applied:
We believe that the customer is the
only one capable to judge and evaluate
the quality of our product.
● Tester/QAs are not a gatekeeper of quality.
● Only customers can say if the product solves theirs problem.
● Testers evaluate the quality criteria that are important to the customers and share the information.
We use data extensively to deeply
understand customer usage and then
close the gaps between product
hypotheses and business impact.
● Know the users/customers.
● Build (actionable) ways to measure the business impact.
● Evaluate and adapt.
We expand testing abilities and
knowhow across the team;
understanding that this may reduce (or
eliminate) the need for a dedicated
testing specialist.
● Expand know hows.
● Generalizing Engineer.
● Elimination of dedicated specialist is context based.
