To use clickers
When you get to class change your clicker to
the proper clicker channel.
What is a channel?
Clickers work like Walkie Talkies. They require
the clicker and the receiver (plugged into the
computer) to be on the same channel to accept
answers.
WE WILL ALWAYS USE CHANNEL 1

To answer questions:
Make sure clickers are in Presentation Mode
Presentation Mode allows clickers to send answers
NOTE: Sending a Message is not sending an answer.
Sending a message is a different function than Presentation
Mode. If you are using an NXT clicker and you see a back
arrow on the display screen in the bottom left corner, keep
hitting that button until it disappears. At that point you are
back in presentation mode.

Writing a test
@Test annotation
defines test data, expected (correct) answer,
computes actual answer
compares expected and actual using assertTrue
© Dr. Carl Alphonce
@Test public void sampleTestMethod() {
ArrayList<String> list = new ArrayList<String>();
list.add("Fred");
list.add("Wilma");
int expected = 2;
int actual = list.size();
assertTrue("I expected the size to be " +
expected + " but it was " + actual,
actual == expected);
}
