Automate or Die!

“Real World Automation
Survival”
Automate or Slave!“Let us remember that the automatic machine ... is the precise economic equivalent of slave labor. Any labor which competes with slave labor must accept the economic conditions of slave labor. It is perfectly clear that this will produce an unemployment situation”
Norbert WeinerThe Human Use of Human Beings,
1950, pg 162
"...automation makes it possible to do many things
that could not be done without it..."
John Diebold,
Beyond Automation,
1964, pg 191
@EvilTester
“Automation has turned out to be a much more complex and difficult problem than was
originally thought.”
John Diebold, Beyond Automation,
1964, pg 51
@EvilTester
“What we need is more automation.”
1948
Ford Motor company VP,
Delmar S. Harder,
Coined “automation” in 1948
@EvilTester
John Diebold,
“Automation”, 1952
"...the author found automatization both awkward and - from the standpoint of his weak spelling - hazardous ... it was the ease of spelling that finally overcame the author's reticence to coin a new word"
@EvilTester
The word “Automation” is...
“barbarous”

'Automation' is Arguable
'Automation' is vague enough that we can argue about it
Testers need to program to do
automation
Testers can do automation without needing to program
@EvilTester
Abstractions
“... what we see, hear, feel, speak about or infer, is never it, but only our human abstraction about 'it'.”
The Role of Language in the Perceptual Process
Alfred Korzybski

@EvilTester
Testers need to program to write code that will automate this
scenario
Control your
specific language
Testers can identify the paths through the system that we
will automate without needing to program
@EvilTester
Automating is often a hunt for
workarounds

do testers need to
become?Challengers of the Unknown, DC Comics, #20, 1961

“Whatever you might say something "is", it is not.”

BDD● BDD is not about testing● BDD is not about tools● BDD Tools are not testing tools
“If BDD tools aren't test tools why do we use them as part of our test approach?”
@EvilTester
I use Cucumber...● … as a tool for creating Domain Specific
Languages● … to easily document and implement data
driven scenarios
@EvilTester
The solution to problems when automating is rarely
more automating

Abstraction Layers“We all know that the only mental tool by means of which a very finite piece of reasoning can cover a myriad cases is called “abstraction””
The Humble Programmer
Edsger W. Dijkstra
ACM Turing Lecture 1972http://bit.ly/1MVghiP
@EvilTester
@Testpublic void canCreateAToDoWithNoAbstraction(){ driver.get(
"http://todomvc.com/architecture-examples/backbone/");
int originalNumberOfTodos = driver.findElements(By.cssSelector("ul#todo-list li"
)).size();
WebElement createTodo = driver.findElement(By.id("new-todo"));
createTodo.click(); createTodo.sendKeys("new task"); createTodo.sendKeys(Keys.ENTER);
assertThat(driver.findElement(By.id("filters")).isDisplayed(), is(true));
int newToDos = driver.findElements(By.cssSelector(
"ul#todo-list li")).size();
assertThat(newToDos, greaterThan(originalNumberOfTodos));
}

Abstraction Layers“... the purpose of abstracting is not to be vague, but to create a new semantic level in which one can be absolutely precise.”

@Test public void canCreateAToDoWithAbstraction(){ TodoMVCUser user =
new TodoMVCUser(driver, new TodoMVCSite());
user.opensApplication().and(). createNewToDo("new task");

new TodoMVCSite());
assertThat( page.getCountOfTodoDoItems(), is(1));

And how do you find time to test when you
are automating so much?

Survival is a way of thinking...
“Automation requires us to view the production processes as an integrated
system... Automation is a way of thinking, a way of 'looking at...' as much as it is a way of
doing... It is an attitude... rather than a particular technology”
John Diebold, Applied Automation. A Practical Approach,
p. 3 1955
