QA Testing: Why Your Software Fails When It Goes to Production
Software testing
It is every Product Owner’s horror story: The development team confirms everything is ready. The tests on their computers were successful. You launch the new feature on a Friday afternoon, and two hours later, tech support is flooded with complaints. The shopping cart isn’t working, the app crashes, or the data won’t load.
What happened? Did the developers lie to you?
Probably not. The problem is that you relied on “luck” instead of relying on a professional Quality Assurance (QA) process.
Production bugs are costly, not just in money, but in reputation. Regaining the trust of a frustrated user is much harder than retaining them. Below, we explain why the famous “it worked on my machine” happens and how rigorous software testing is the only life insurance for your project.
The “It Works on My Machine” Syndrome
This is the most common abyss between development and reality.
A developer works in an “ideal environment”: they have a perfect internet connection, clean test data, and specific hardware configuration. But your real users have unstable connections, older devices, and unpredictable behaviors.
If you don’t have a Staging environment (pre-production) that mimics the chaos of the real world, you are playing Russian roulette.
Key Insight: QA isn’t about “breaking” the developer’s code; it’s about simulating reality before it hits your business.
Manual vs. QA Automation: The Need for Speed and Precision
Traditionally, software testing was done by hand. A person would click every button to see if it worked. This is useful for user experience, but it is slow and error-prone as the software grows.
This is where QA automation comes in.
At Koud, we program “bots” that run thousands of tests in seconds every time a developer saves a change.
- Did the change in the login break the registration? The bot detects it.
- Is the database responding slowly? The bot alerts us.
QA automation is what allows large companies to release daily updates without fear of breaking what was already working (Regression Testing).
The Testing Pyramid: A Solid Structure
To avoid production bugs, it is not enough to test “on the surface.” A robust QA strategy follows a pyramid:
- Unit Tests (Base): Each small function of the code is tested in isolation.
- Integration Tests (Middle): Verifies that modules (e.g., Payments + Inventory) talk to each other correctly.
- End-to-End Tests (Tip): Simulates the full flow of the end-user, from login to checkout.
If your current provider only does the latter (and manually), you are leaving 80% of your code unverified.
The Cost of Fixing Late
There is a rule in software engineering: The cost of a bug multiplies by 10 at each stage.
- Detecting it in Design: $1 USD.
- Detecting it in Development: $10 USD.
- Detecting it in QA: $100 USD.
- Detecting it in Production (with the client): $1,000 USD + Brand Damage.
Investing in early software testing is not an extra expense; it is a massive savings in the medium term. It is the difference between cheap preventive maintenance and an expensive emergency repair.
How Koud Guarantees Your Peace of Mind
At Koud.mx, quality is not an isolated department; it is a culture. We do not deliver code that has not passed through our continuous integration pipelines.
We use market-leading QA automation tools to ensure that when we say “it’s ready,” it really is. Because we know your reputation is on the line.
Frequently Asked Questions
Does QA Automation replace human testers?
No. It complements them. Automation takes care of the repetitive and tedious tasks, freeing up human testers to perform “Exploratory Testing,” where they use their creativity to find logical or usability errors that a robot wouldn’t see.
Will adding QA make development slower?
At first, it may seem like it adds setup time. But from the second Sprint onwards, speed increases drastically because developers spend less time fixing production bugs and more time creating new features.
What types of software testing do I need for my App?
At a minimum, we recommend Unit Tests (for internal logic) and API Integration Tests. If your app is mission-critical, adding Stress Testing is vital to ensure it handles many simultaneous users.
Conclusion
Launching software without professional testing is like launching a car onto the market without testing the brakes. The engine might start, but disaster is imminent.
Technical excellence is what builds customer loyalty. Implementing rigorous software testing and QA automation strategies is the sign of a digital product’s maturity.
