How to use the guides¶
Every beginner guide follows the same layout, so you always know where to look.
| # | Section | What you get |
|---|---|---|
| 1 | At a glance | The four or five numbers that matter most for the test |
| 2 | What does the test prove? | The purpose in plain language |
| 3 | The test rig | A picture of the set-up with numbered parts |
| 4 | Values for your size | One tab per size (02 / 04 / 06 / 08) |
| 5 | The whole test as a flow chart | The full sequence on one screen |
| 6 | Step by step | Tick-boxes for each step, with why and stop boxes |
| 7 | Pass or fail? | The acceptance criteria |
| 8 | Common mistakes | What usually goes wrong for beginners |
| 9 | Open points | Links to the backlog items that affect this test |
What the coloured boxes mean¶
Why?
Explains the reason behind a step. Read it the first time; skip it once you know the test.
Stop
Do not continue. Something is wrong or unsafe. Fix it, or ask the test lead.
Tip
A practical trick that saves time or avoids a re-run.
Internal proposal
The specification does not say this. It is our own interpretation and must be approved before the test result is used in a report. Each one is linked to an ID in the backlog.
