1
00:00:01,930 --> 00:00:05,790
In this video we're going to try to write out a test just to make sure that a user cannot sign up at

2
00:00:05,800 --> 00:00:07,230
the same email twice in a row.

3
00:00:07,580 --> 00:00:10,200
So I'm gonna go back over to my sign up test file.

4
00:00:10,260 --> 00:00:11,630
I'm down at the very bottom.

5
00:00:11,650 --> 00:00:18,220
I'm gonna write out a new block and I'll give it a description like it disallows duplicate emails

6
00:00:21,780 --> 00:00:22,540
than inside of here.

7
00:00:22,560 --> 00:00:26,970
We'll attempt to sign up the same email and password combination twice in a row.

8
00:00:27,060 --> 00:00:33,390
The first request we will expect to give us back a response of 2 0 1 which indicates that the sign up

9
00:00:33,390 --> 00:00:35,580
was successful as we did back up here.

10
00:00:35,580 --> 00:00:37,990
Well then duplicate that request once again.

11
00:00:37,990 --> 00:00:41,190
And on the second request we'll just expect to get back a four hundred.

12
00:00:41,190 --> 00:00:46,260
Because remember if an email is already in use we throw a bad request error which is going to send a

13
00:00:46,340 --> 00:00:55,990
200 or a 400 says code back to the user so inside that new block we'll do it in await request on app.

14
00:00:56,070 --> 00:01:01,820
We'll make a post request to API users sign up.

15
00:01:02,010 --> 00:01:09,020
We will send along an email test at test dot com and a password of password.

16
00:01:09,190 --> 00:01:11,110
And then finally we'll put on an expectation.

17
00:01:11,140 --> 00:01:14,890
So in this case again the first request sign up should be successful.

18
00:01:14,890 --> 00:01:17,720
So we should get back to a 1.

19
00:01:17,760 --> 00:01:25,560
Now we can duplicate that total copy paste it down and then on the second one all we're going to expect

20
00:01:25,750 --> 00:01:29,480
different is a responsive four hundred or a status code of 400.

21
00:01:29,710 --> 00:01:31,530
They'll put in 400 instead.

22
00:01:31,950 --> 00:01:33,090
Let's save that.

23
00:01:33,390 --> 00:01:40,070
Check the terminal where's my test window here this looks good.

24
00:01:40,220 --> 00:01:40,520
All right.

25
00:01:40,520 --> 00:01:42,740
There are a couple of more tests I'd like to put together very quickly.

26
00:01:42,770 --> 00:01:45,530
So quick pass one or two more tests in the next video.
