The Act step calls the “abs” function using the “negative” variable and stores the returned value in a variable named The Assert step verifies that “answer” is a positive value. The AAA (Arrange-Act-Assert) pattern has become almost a standard across the industry. It suggests that you should divide your test method into three sections: arrange, act and assert.
