1 00:00:00,450 --> 00:00:06,210 So now we have to write a test for our handlers that take posts, and if we look at our setup underscore 2 00:00:06,210 --> 00:00:08,370 test go, we see there are three. 3 00:00:08,370 --> 00:00:14,530 There's one for search availability, one for search availability, Jassam and one down here for make 4 00:00:14,530 --> 00:00:15,290 a reservation. 5 00:00:15,330 --> 00:00:16,560 So let's set those up. 6 00:00:17,190 --> 00:00:21,720 So the first thing we'll do is set up the test as part of our the tests variable. 7 00:00:22,170 --> 00:00:28,980 So we're going to have a test for first of all, let's do post search availability. 8 00:00:29,550 --> 00:00:30,960 And that's just the name of the test. 9 00:00:31,110 --> 00:00:39,450 You URL is slash search availability bill it t spelled, right? 10 00:00:39,480 --> 00:00:40,110 Yeah, I think so. 11 00:00:40,770 --> 00:00:49,560 And it's going to be a post request and this will take a slice of post data and we need to specify the 12 00:00:49,560 --> 00:00:51,110 necessary information for that. 13 00:00:51,480 --> 00:00:56,360 So each entry in the post data consists of a key and a value. 14 00:00:56,370 --> 00:01:02,520 The key is the name of the form element, the form input and the values, whatever is typed in there. 15 00:01:02,520 --> 00:01:03,750 So we can just go. 16 00:01:05,280 --> 00:01:15,000 Key and for post search availability, I think we have to start as the name and value, which is a date 17 00:01:15,000 --> 00:01:18,300 put 20, 20 year one zero on any validate will do. 18 00:01:19,440 --> 00:01:24,410 And we have another one for and Ellen will just make it a different date. 19 00:01:25,320 --> 00:01:30,810 And finally, we have to specify what we want to get back HDB status. 20 00:01:30,820 --> 00:01:32,660 OK, all right. 21 00:01:32,670 --> 00:01:37,140 So there's one less copy this and paste it. 22 00:01:37,860 --> 00:01:42,110 And the second one is for Jason Post search availability. 23 00:01:42,120 --> 00:01:43,560 Jason, that's my name. 24 00:01:43,560 --> 00:01:46,530 And the actual euro you URL is Jason at the end of that. 25 00:01:47,430 --> 00:01:49,560 And the last one is for reservation. 26 00:01:54,680 --> 00:02:02,840 And we'll call this make reservation post, but it doesn't take start and end, it takes first name, 27 00:02:03,680 --> 00:02:08,840 which will make John and these correspond to the actual inputs on the form. 28 00:02:09,350 --> 00:02:10,790 Last name will be Smith. 29 00:02:15,890 --> 00:02:23,180 And then it takes an email address me at here dot com and it takes a phone number, which can be anything. 30 00:02:25,370 --> 00:02:29,520 And we'll make it Phi Phi Phi Phi Phi Phi Phi Phi Phi Phi Phi. 31 00:02:30,080 --> 00:02:30,520 All right. 32 00:02:30,710 --> 00:02:33,610 So there are the actual test data entries. 33 00:02:33,980 --> 00:02:37,950 Now we have to perform the tests and it's not that difficult. 34 00:02:37,970 --> 00:02:39,020 So we do that here. 35 00:02:39,380 --> 00:02:42,710 If method is not equal to get, then it must be equal to post. 36 00:02:42,710 --> 00:02:51,830 So the first thing we need to do is to construct a kind of variable that is in the format that our test 37 00:02:51,830 --> 00:02:53,490 server expects to receive things in. 38 00:02:53,510 --> 00:02:58,010 And that's a variable that corresponds to what we're posting in the form, and we can do that really 39 00:02:58,010 --> 00:02:58,340 easily. 40 00:02:59,000 --> 00:03:03,890 So first of all, we'll create an empty variable in the form that is required by the method. 41 00:03:03,900 --> 00:03:06,860 We're going to call on our test server and we'll call that values. 42 00:03:07,370 --> 00:03:14,390 And that's going to be an empty euro values, which is a built in type part of the standard library 43 00:03:14,840 --> 00:03:19,070 that holds information as a post request for a variable. 44 00:03:19,400 --> 00:03:22,600 Now, we need to populate that with with actual our actual entries. 45 00:03:22,610 --> 00:03:30,050 So we'll just range over our parameters, variable set in the current test that we're running. 46 00:03:30,050 --> 00:03:34,820 And we do that like this for underscore because we don't care about the index and we'll just a variable 47 00:03:34,820 --> 00:03:37,130 called X is equal to range. 48 00:03:37,700 --> 00:03:38,600 Iida perhaps. 49 00:03:40,640 --> 00:03:47,060 And as we go through that, we'll just populate values into that values variable, which we do use using 50 00:03:47,060 --> 00:03:47,720 a built in method. 51 00:03:47,720 --> 00:03:56,170 Values don't add and values add expects to things the key and the value extract key export value. 52 00:03:57,260 --> 00:04:01,460 And now we have our values variable populated with everything necessary to make our post. 53 00:04:02,390 --> 00:04:06,370 So once we've done that, we now have to call our test client again. 54 00:04:06,380 --> 00:04:07,910 But we use a slightly different version. 55 00:04:07,910 --> 00:04:13,130 This time we still get a response and we still potentially get an error, which will be nil if everything 56 00:04:13,130 --> 00:04:14,270 works the way it's supposed to. 57 00:04:14,840 --> 00:04:18,130 And we call it on our test variable, which is our test server. 58 00:04:18,620 --> 00:04:23,120 And again, we call client, but this time we call post form. 59 00:04:23,840 --> 00:04:30,020 And post form requires two things the URL you want to post to and the values you want to post so that 60 00:04:30,020 --> 00:04:31,100 you are we want to post. 61 00:04:31,100 --> 00:04:32,570 It was exactly the same as it was. 62 00:04:32,570 --> 00:04:42,370 And yet it's the the euro for the test server, which is stored in euro plus idot euro euro. 63 00:04:42,380 --> 00:04:44,240 We want to test and values. 64 00:04:44,270 --> 00:04:46,480 It's just the values that we created just a moment ago. 65 00:04:47,360 --> 00:04:52,430 So now we can just do exactly the same thing we can and we can actually copy what we did in our request 66 00:04:52,430 --> 00:04:58,430 so we can copy this, paste it here and everything should work. 67 00:04:58,440 --> 00:04:59,270 So what are we doing? 68 00:04:59,570 --> 00:05:01,190 We get our response and our error. 69 00:05:01,190 --> 00:05:02,720 If there's an error, fail the test. 70 00:05:02,720 --> 00:05:04,160 If there's no error, keep going. 71 00:05:04,430 --> 00:05:08,930 And we check our expected status code with the status code we actually get. 72 00:05:09,020 --> 00:05:10,910 If they don't match, then we have an error. 73 00:05:11,600 --> 00:05:16,760 So let's go back to our terminal window and clear the screen and try running this test. 74 00:05:17,000 --> 00:05:18,090 I'm in the correct directory. 75 00:05:18,090 --> 00:05:18,620 Yes, I am. 76 00:05:18,620 --> 00:05:23,330 Go test dashboard and let's see if we got it right and it failed. 77 00:05:23,330 --> 00:05:29,530 And one fail is for make reservation post expected 200, but got 400. 78 00:05:29,570 --> 00:05:31,160 Well, what is HDB status? 79 00:05:31,160 --> 00:05:31,730 400. 80 00:05:32,150 --> 00:05:33,980 That's actually bad request. 81 00:05:34,520 --> 00:05:38,510 And we there's one thing we didn't do that we actually have to do and it's pretty easy to fix. 82 00:05:38,780 --> 00:05:46,120 So if we go back to our setup test, you remember when we set up our routes, we said use the no surfed 83 00:05:46,130 --> 00:05:52,970 handler, our middleware and no surf actually checks for cross site request forgery. 84 00:05:53,210 --> 00:05:58,310 And it expects to find a token called CSF token in the post request. 85 00:05:58,610 --> 00:06:00,590 And we actually didn't populate that. 86 00:06:00,950 --> 00:06:02,900 And I'm not going to at this point. 87 00:06:02,910 --> 00:06:08,570 So one way to fix this is to simply comment that because I'm not testing my no serve handler, I've 88 00:06:08,570 --> 00:06:12,200 already done that of my middleware and I can do it elsewhere if I want to. 89 00:06:12,200 --> 00:06:16,310 It's really not critical for testing this particular method by itself. 90 00:06:16,640 --> 00:06:22,880 So I'm going to comment that I go back to my term, my terminal window, clear the screen and run that 91 00:06:22,880 --> 00:06:23,480 test again. 92 00:06:23,480 --> 00:06:24,680 And this time it should pass. 93 00:06:26,260 --> 00:06:32,590 And it does so there is one method of testing postal handlers that handle posts. 94 00:06:32,620 --> 00:06:38,620 Now, obviously, we probably want to check for things other than just the correct status code coming 95 00:06:38,620 --> 00:06:38,920 back. 96 00:06:38,930 --> 00:06:47,020 So, for example, what if in this test someone somehow submits a value that's not a date for this this 97 00:06:47,020 --> 00:06:48,780 post or for this post? 98 00:06:49,240 --> 00:06:53,770 What if they don't put a valid email address in here and we're not checking for any of that right now 99 00:06:53,770 --> 00:06:56,590 and we will will improve these tests as time goes on. 100 00:06:57,220 --> 00:07:01,660 But before we can really do that, it would be useful to be able to connect to a database, store some 101 00:07:01,660 --> 00:07:05,910 information in that database and actually handle that part of our application. 102 00:07:05,920 --> 00:07:11,290 So we'll be coming back to these tests and adding to them and adding additional tests as time goes on. 103 00:07:12,400 --> 00:07:18,490 So in the next section, we'll have a look at testing our render package and then we'll check coverage 104 00:07:18,490 --> 00:07:22,120 and look at what we have to do to actually run our application right now. 105 00:07:22,120 --> 00:07:25,210 Because if we try to run our application, I'll just show you right now. 106 00:07:25,210 --> 00:07:26,350 We'll do it easier way later. 107 00:07:26,740 --> 00:07:30,520 If I try to run this, I'm in my directory and I do what we've been doing right along. 108 00:07:31,000 --> 00:07:34,070 Go run command web, start on, go. 109 00:07:34,120 --> 00:07:39,430 It's not going to work and it's not going to work because we cannot run test go test files. 110 00:07:40,000 --> 00:07:51,730 Now, we can get around that by saying go run command web and then may not go and command web middleware. 111 00:07:52,210 --> 00:07:57,820 Don't go and command web rootstock. 112 00:07:57,820 --> 00:07:59,140 Go and then it will run. 113 00:08:01,400 --> 00:08:06,770 But there's a shorthand we can do this, we can write a little batch file or a shell script that'll 114 00:08:06,770 --> 00:08:09,140 make it easier for us, and we'll do that in a couple of lectures.
