SE 3800 Note 6 UI Testing

2. UI Testing in Java Assumption: painful but readily available
Research: lots of vaporware, abandonware
Many solutions for web, but not a lot for Java
FrogLogic, RAutomation, MarathonTesting, UISpec4J, Mspec, abbot
Method that works:
JavaWorld TestUtils; see also counter.zip

3. UI Testing in Java Each component: call .setName with unique string
Test code:
TestUtils.getChildNamed(frame,
name-of-child)
Use .doClick, .value(), etc. to exercise code
Robust
Doesn’t depend on screen locations, specialized test frameworks
But no auto-capture/replay

4. UI Testing in C++ w/ Cucumber
Feature: Subtraction
In order to avoid silly mistakes
As a math-challenged person
I want to be told the difference of two numbers
Scenario Outline: Subtract two numbers
Given I just turned on the calculator
When I press <button1>
And I press subtract
And I press <button2>
And I press calculate
Then the display should show <result>
Examples:
| button1 | button2 | result |
| | | |
| | | |
| | | |

REGEX_PARAM(unsigned int, n);
cucumber::ScenarioScope<CalculatorWidget>

8. Acceptance Tests & APIs
How to write acceptance tests for an API?
Our model: acceptance test = story/scenario
Issue: an API is not a user!
Solution: Cohn: Writing User Stories for Back-end Systems
Personify subsystems
Epic: “As a bank, I want to receive a file showing all checks to be cleared so that I can debit and credit the right accounts.”
“As a bank, I want to receive a 5300 file with correctly formatted single-line deposit entry records so that I can process them.”
Write test to the resulting story.
