Answer 1

Lines 23-­24

'describe' is a RSpec Keyword, which is used to define an group of example. Its is a collection of different tests. It takes a class name and/or string argument. do and end are the keywords which are used to select the action. Here Career is a class name and with the 'career getters and setters' method which will used to set career and job related information.

'do' and 'end' are the keywords followed by the arguments/class name. do will act like the starting of the describe and end will be the stop of the same.

describe uses block with arguments.

Lines 26­-28

'it' is also a keyword in RSpec, it is used to define the example or test case.

Here we want to set name ( name as a test case), line 26 is the initialisation of it block with the argument 'should set job' mean we have to assign some values to parameter 'job' in the block of 'it' which is on line 27. On line 27, 'expect' keyword is used to as a verification step or what we are expecting to assign. i.e. here in name of career getter should be 'John'. Here 'expect' keyword is followed by destination and 'to' keyword and 'eq' keyword. That is expect(destination) to eq (means value should be 'John'). So it will set name= John.
As every expect is terminated with the 'end' keyword.

Lines 29­-30

Same as above, just the difference is above it was Name to set here 'Job' is the argument to be set.
so this block will set Job=firefighter.

Lines 32­-35

RSpec works like general English. Here in this block we want to update the name, hence we have passed the argument to 'it' as 'should be able to change name'. So we will implicitely assigning @careers.name='Jonathan' and same will be accomplished by the 'expect'-as 'expect' is used as verification step here.

'end' is used to complete the block.

Lines 36­-39

Same like line 32--35, here we are updating the job parameter. We are assigning @careers.job=
Parametic' and verifying with the 'expect' block.

'end' is used to complete the block.
