When testing a booking store, everything looked fine on desktop. Only when we ran through real bookings did the bugs surface: wrong totals in the cart, shipping copy for a product that never ships, cut-off buttons on mobile and mixed languages in the foreign-language versions. We traced every bug individually and fixed it where it originated. Some were in the theme, some in the booking app. The lesson: a booking system is only tested once every combination has been booked all the way through.
The case
With a booking product, the price depends on many factors at once: date, rate, season, extras, deposit. An error in that calculation doesn’t stand out at a quick glance. It stands out when a guest sees a different amount than expected, and then the trust is gone.
Our test matrix
Instead of clicking through once, we combined systematically:
- Language: every language version separately
- Device: desktop and mobile
- Date and rate: high and low season, different start times
- Extras: none, one, several
- Path: product page, cart, checkout, confirmation email
Every combination was run through to confirmation. Only then do the bugs show up that only occur in one specific combination.
Theme or app?
A big part of the work was figuring out where each bug belonged. A cut-off button is usually a theme issue, a wrong total often an app issue. Bugs that sat in the app we passed to the provider with a precise description, instead of patching around them in the theme. That fixes the problem in the right place.
One more detail: standard copy from regular e-commerce, such as shipping and delivery times, has no place in a booking store. It has to be deliberately removed or adapted.
Your takeaways
- A desktop check isn’t a test. With bookings, every combination counts, all the way to confirmation.
- Build yourself a test matrix. Language, device, date, rate and extras, combined systematically.
- Separate app bugs from theme bugs. That’s the only way the fix lands in the right place.
- Remove copy that doesn’t fit. Shipping notes on an experience confuse more than they explain.
