Testing that gives teams confidence
Testing is a decision activity
Test what could hurt users
Speaker notes
Testing is a way to gather evidence before making a release decision.
Start with risk
- What can go wrong?
- Who is affected?
- How likely is it?
- How expensive is the failure?
- How quickly must we know?
Speaker notes
Testing priorities should follow risk. A payment, permission, or data-loss path deserves more attention than a cosmetic change.
Different tests answer different questions
- Unit — small rule
- Integration — components together
- API — contract
- UI — user flow
- Exploratory — what we did not predict
Speaker notes
No single test type proves a feature is safe. The goal is a useful mix with fast feedback.
The test pyramid is a trade-off
- Many focused checks
- Fewer integration checks
- A small number of end-to-end journeys
Speaker notes
Lower-level tests are usually faster and more precise. Higher-level tests validate the user journey but can be slower and more fragile.
Write a strong test case
- Clear precondition
- One behavior
- Concrete input
- Observable result
- Useful name
Speaker notes
“Test signup” is not useful. “A user cannot save an application without a company name” is specific and observable.
Demo: test the application flow
- Happy path
- Missing required field
- Invalid date
- Duplicate submission
- Unauthorized user
Speaker notes
Create or show tests at more than one layer. Explain why each case exists and what risk it covers.
Pause: build a risk matrix
- Three failure modes
- Impact of each
- Best test type
- Automation candidate
Speaker notes
Pause the video. The point is prioritization, not producing the longest test list.
