My 2025 Context & Testing Strategy: 7 Shocking Results
Discover the 7 shocking results from my 2025 context-driven testing strategy. Learn why we deleted 40% of tests, why bug counts are dead, and more.

Principal Quality Engineer focused on systems thinking and context-driven testing strategies.
For years, my team and I were stuck in a testing paradox. Our test suites were growing exponentially, CI/CD pipelines were slowing to a crawl, and yet, frustrating bugs still found their way to production. We were following all the best practices—the testing pyramid, 100% code coverage goals, extensive end-to-end automation—but it felt like we were running faster just to stay in the same place. We were measuring activity, not impact.
So, at the start of last year, we threw out the rulebook. We embarked on a radical new approach we called the "Context-First Strategy." Instead of asking, "How can we test this?" we started asking, "What is the risk to the user and the business if this fails?" This simple shift in perspective changed everything. It forced us to think about user behavior, business goals, and production realities *before* writing a single line of test code.
The results weren't just positive; they were genuinely shocking. They challenged some of our most deeply held beliefs about quality assurance. Here are the seven most surprising outcomes of our 2025 context-and-testing strategy.
1. We Deleted 40% of Our E2E Tests (And Our Effective Coverage Increased)
This one felt like heresy. We'd spent years building a massive suite of browser-based, end-to-end (E2E) tests. But our context-first audit revealed a harsh truth: most of them were redundant, brittle, and slow. They tested happy paths that were already covered by lower-level tests or focused on UI elements that had no bearing on core user journeys.
We ruthlessly pruned any E2E test that didn't represent a critical, revenue-impacting user flow. The result? Our test suite ran 60% faster, providing quicker feedback. The remaining tests were more stable and meaningful. By focusing our efforts on the tests that truly mattered—the ones that mirrored real-world, high-stakes user behavior—our *effective* coverage of business risk went up, even as our raw test count plummeted.
2. "Bug Count" Became a Vanity Metric; "User Frustration Incidents" Took Over
We used to celebrate a high bug count in a release cycle. It meant QA was "working." But we realized we were optimizing for the wrong thing. A typo is a bug. A catastrophic failure to process a payment is also a bug. They are not equal.
Our new key metric is "User Frustration Incidents." We defined this by combining data from our observability tools:
- Rage Clicks: Multiple clicks on an unresponsive element.
- Error Spikes: A sudden increase in 5xx or 4xx errors tied to a specific feature.
- Negative Session Replays: Watching users fail to complete a key workflow.
- Support Ticket Correlation: A surge in tickets about a particular feature.
Focusing on reducing these incidents has aligned our engineering efforts directly with improving the user experience and protecting revenue. A low bug count means nothing if user frustration is high.
3. Developers Finally Started Owning Quality (No, For Real This Time)
"Shift-left" and "devs own quality" have been buzzwords for a decade, but they rarely stick. The problem is usually tooling and context. A developer in their IDE doesn't have the same context as a tester analyzing a user journey.
We fixed this by bringing the context *to* the developer. We integrated lightweight contract and component tests directly into their pre-commit hooks. More importantly, we piped production-context data into their local environments. A developer could now run their feature against anonymized data schemas and API behaviors that mirrored production. The feedback loop became immediate: "If I commit this, I will break the checkout flow for users in Germany." This made quality tangible and the ownership real.
4. Our Best Testers Are Now Called "Product Anthropologists"
The role of a senior QA analyst has fundamentally changed. They are no longer just expert test case writers or automation engineers. Their most valuable skill is now understanding human behavior within our product's ecosystem.
Our "Product Anthropologists" spend less time in test management tools and more time in:
- Product Analytics Tools (like Amplitude): To see what users are *actually* doing.
- Session Replay Tools (like FullStory): To see *how* they are doing it and where they struggle.
- User Interviews: To understand the *why* behind their actions.
They bring this qualitative and quantitative data back to the team to create test strategies that are laser-focused on real-world usage and risk, not on imaginary edge cases.
5. The Testing Pyramid Evolved into a "Testing Diamond"
The classic testing pyramid is a great starting point: lots of fast unit tests at the base, fewer integration tests, and very few slow E2E tests at the top. However, in a world of microservices and complex third-party APIs, it's a bit outdated.
We found that the most critical—and most frequent—point of failure was at the seams between services. Our strategy evolved into a "Testing Diamond."
The Testing Diamond: It starts thin at the bottom with unit tests (important, but they don't test connections). It becomes widest in the middle, emphasizing Component and Contract Testing to ensure services and APIs communicate correctly. Then, it narrows again at the top with a very small number of true E2E user journey tests.
This model better reflects the distributed nature of modern applications and focuses our efforts where the risk is highest: the interactions between parts.
6. Performance Testing Became Continuous Observation, Not a Pre-Launch Gate
The big, scary, pre-launch load test is dead. It's expensive, it rarely mimics real-world traffic patterns, and it happens too late in the cycle. If you find a major performance issue a week before launch, what can you do?
Our new approach is continuous and observational:
| Old Way (Event) | New Way (Process) |
|---|---|
| One-time load test before a major release. | Continuous monitoring of Core Web Vitals (LCP, FID) in production. |
| Synthetic traffic from a load testing tool. | Alerting on real-user performance degradation for key transactions. |
| Pass/Fail gate based on arbitrary response times. | Small, regular chaos experiments in staging/canary environments to test resilience. |
Performance is no longer a last-minute check; it's a feature we monitor and iterate on constantly, just like any other part of the product.
7. Exploratory Testing Delivered More ROI Than Automation Sprints
Here's the most controversial result. We didn't stop automating, but we stopped treating it as the ultimate goal. Automation is fantastic for confirming that what we know *should* work, still works (i.e., regression). It's a defense mechanism.
However, the most severe, brand-damaging bugs we found came from exploratory testing—unscripted, intelligent, context-driven investigation by our Product Anthropologists. These were the "unknown unknowns" that no scripted test would ever find: complex usability flaws, security loopholes in weird user flows, and unexpected interactions between systems.
We now dedicate a fixed percentage of every sprint to this kind of creative, human-led testing. The return on investment, measured in the severity of bugs found versus the time spent, has been astonishingly high compared to writing yet another brittle E2E script.
Conclusion: A Mindset, Not a Method
Our journey into a context-driven testing strategy for 2025 has taught us one crucial lesson: quality isn't about following a rigid process or hitting a specific metric. It's about cultivating a mindset focused on risk, user experience, and business impact.
By throwing out old dogmas and embracing a flexible, context-aware approach, we've not only improved our product but also made our engineering process faster, more efficient, and infinitely more rewarding. The most shocking result of all? We're no longer just testing software; we're actively building a better product.
