Chaining the BeastTesting Wonder Applications in the Real World

Ray Kiddy, DynEd International1

• We enjoy the pain.

• We talk about it so we do not have to do more of it.

• We do not talk about it very often.

Why Talk About Testing?

3

Regressions New Features

MisConfig WTF?

Appearance

View

Controller

Model

Data

• MVC - everyone should know what this is about...

• Data Source - likewise...

• Appearance - Does the application actually look right to human eyes?

4

• Catch Regressions - something is true today, should be tomorrow also.

• Check New Features - if something is new, it might not be perfect.

• Expect Problems - Murphy’s Law.

• WTF?

5

• Data import is not always correct.

• Input is not always sensible

• Page responses are too slow

• Not a lot of time to work on it, suckiness.

WOLeg

Methodologies

• With apologies to Frank Zappa

7

Information is not Knowledge

• Do you trust your data source?

• Tests executing at launch, every time.

• Check data schemas against expected.

• Runs every single launch, except when it does not.

8

Knowledge is not Truth

• Verify Models

• Manipulate (?) to match reality

• Tests of business logic using model info only!

9

Truth is not Wisdom

• KVC is your friend

• KVC will kill you

• Abstraction is power but also causes ignorance.

10

Wisdom is not Beauty

• Info display is good, but what about interactivity?

11

Beauty is not Love

• Verify the appearance of the application.

12

Love is not Music

• How to make sure testing gets done.

• Code will grow, get buy-in early.

13

In-Application Testing

• “Up side” - it is always available

• “Down side” - it is always available

• Drove choices via properties AND “marker” files
