The discount stopped applying
This journey passed last week with a $72 total. Today, the same product and code returned $80.
- Expected
- $72.00
- Actual
- $80.00
Likely cause: Backend
Replaying illustrative run…
Same symptom. Different cause.
The customer sees $80. Switch the backend result to see why the diagnosis changes.
- Expected result
- $72.00
- Backend returned
- $80.00
- Customer saw
- $80.00
Likely cause: Backend
The backend returned $80 without the discount. The screen displayed that result correctly, so the issue is in the backend calculation.

Illustrative pricing responses from the same journey in two runs.
Last passing run

"discountAmount": 8,
"total": 72
}Current run
{
"productPrice": 80,
"discountCode": "WELCOME10",
"discountAmount": 0,
"total": 80
}The discount changed from $8 to $0. The screen matched the backend total in both runs, pointing to a backend regression.
Checkout example. Changed since last pass. The discount stopped applying. Expected: $72.00. Actual: $80.00. Likely cause: Backend.
Turn everyday tasks
into repeatable tests
Start with a customer journey you check before each release. Tell QABrains what to do and what a successful result looks like.
Describe the journey
Tell QABrains where to start and what to do, such as buying a product with a discount code.
Set the expected result
Specify what a pass looks like: the right total, a saved booking, or the dashboard after signup.
Review the diagnosis
Run the test to see where it failed, whether the evidence points to the UI or backend, and what changed from a previous run.
See what changed.
Know where to fix it.
Compare each journey with a previous run you trust. QABrains flags regression drift: changes in behaviour you previously verified.
Then it compares what the customer saw with what the backend did to trace the failure to the right layer. Here, signup now ends at sign-in despite a valid backend session, pointing to a UI redirect issue.
Your team decides whether a difference is a bug or an intentional change.

Getting started
with QABrains
Have a customer journey you want to test? Tell us about your website or app, and we’ll discuss what you can test during early access.
We’ll reply within two business days.
What do I need for my first test?
Choose a customer journey, its starting point, and an expected result. For example: buy an $80 backpack with a 10% discount and check that the order total is $72.
Does it test websites and mobile apps?
We’re building QABrains for both. Tell us which platform you use so we can discuss support for your product during early access.
Can it distinguish UI and backend issues?
QABrains identifies whether a failure points to the UI or backend. Comparing with a previous run also reveals regression drift, so you can see what changed as well as where to investigate.
What happens after I request access?
Your request starts a conversation with us. We’ll discuss your product, the journeys you want to test, and whether early access is a fit.
