1 00:00:01,950 --> 00:00:07,350 So we need to fix the problem that we have with our tests in our handler package and let's run those 2 00:00:07,350 --> 00:00:10,530 tests again and this time I'll run them right in the handlers directory. 3 00:00:10,540 --> 00:00:13,440 So those are the only tests that I'm running go test. 4 00:00:15,420 --> 00:00:20,670 And if I look at the beginning of this right with the very top, just after I ran the tests. 5 00:00:22,170 --> 00:00:29,010 Which is right here, you'll see that it's calling telling us we have an error in handlers don't go 6 00:00:29,010 --> 00:00:30,210 line 65. 7 00:00:30,240 --> 00:00:33,010 So let's go look at handlers, don't go and see what's going on. 8 00:00:34,410 --> 00:00:37,620 Handlers don't go line 65. 9 00:00:38,190 --> 00:00:43,980 There are Salin, 65 is Helper's server error cannot get reservation from session. 10 00:00:43,980 --> 00:00:49,020 And if you look at all of the errors that were generated there, you'll quickly discover that every 11 00:00:49,020 --> 00:00:54,530 single one of them has to do with the fact that it can't get information from the session. 12 00:00:54,720 --> 00:00:56,580 So clearly we have a problem here. 13 00:00:56,610 --> 00:01:02,250 So let's go look at the actual tests themselves and see how they work so handlers don't test. 14 00:01:02,640 --> 00:01:06,360 The one that we're dealing with is calling the reservation. 15 00:01:06,360 --> 00:01:07,940 And that's this one, right? 16 00:01:10,500 --> 00:01:16,830 Here, make reservation, so make reservation is the route that is failing and it's not passing any 17 00:01:16,830 --> 00:01:17,530 post data. 18 00:01:17,820 --> 00:01:19,890 It's looking for an HTTP status. 19 00:01:19,890 --> 00:01:23,300 OK, and that's the URL that it's calling as a get request. 20 00:01:23,340 --> 00:01:29,850 So if we actually look at the handler itself, again, this is the function that is causing us the problem. 21 00:01:30,000 --> 00:01:32,500 And the problem is it can't get the session. 22 00:01:33,450 --> 00:01:40,020 Well, these tests are set up using setup test, this file right here in the handler's folder. 23 00:01:40,050 --> 00:01:42,020 Let's see if we're doing anything with the section there. 24 00:01:42,780 --> 00:01:48,780 So it looks like we have our imports, we declare some variables and then we have this function get 25 00:01:48,780 --> 00:01:49,200 roots. 26 00:01:49,200 --> 00:01:51,990 And that's what's called right in the tests. 27 00:01:52,350 --> 00:01:54,510 That's what's called before these tests run. 28 00:01:54,540 --> 00:02:00,300 So if I look at the handlers test, what I'm doing is calling get rates, setting up a server and then 29 00:02:00,300 --> 00:02:01,470 just running my tests. 30 00:02:01,830 --> 00:02:03,810 So it's clearly it's not getting the session. 31 00:02:03,810 --> 00:02:04,500 And why not? 32 00:02:04,650 --> 00:02:08,790 Because at no point do we ever put anything in the session. 33 00:02:09,660 --> 00:02:12,310 We need to have access to our request variable. 34 00:02:12,480 --> 00:02:13,590 Well, we have a request. 35 00:02:13,590 --> 00:02:19,500 There's no problem there, but we're not actually putting anything in that request to pull out in that 36 00:02:19,500 --> 00:02:19,950 handler. 37 00:02:20,190 --> 00:02:21,730 So we need some means of doing that. 38 00:02:22,200 --> 00:02:27,540 So what I'm going to do right now is just comment all of this stuff out and get a comment about just 39 00:02:27,540 --> 00:02:31,020 so these tests don't run at all because this is now an empty slice. 40 00:02:31,470 --> 00:02:34,430 It will never run anything in test handlers. 41 00:02:34,770 --> 00:02:40,340 And what I'll do instead is come down here and write a test specifically for the availability. 42 00:02:40,770 --> 00:02:43,080 So how are we going to do that? 43 00:02:43,410 --> 00:02:49,860 Create a new function func and it will be called Test Repository Reservation. 44 00:02:50,550 --> 00:02:51,870 So that's the test I'm going to run. 45 00:02:52,260 --> 00:02:58,500 But before I do that, I need to have access to a request variable that I can put a sessional variable 46 00:02:58,500 --> 00:03:00,690 in before I call that handler. 47 00:03:01,140 --> 00:03:05,250 So I'm going to go back to my setup tests and I'm going to make some changes here. 48 00:03:05,280 --> 00:03:08,190 First of all, I'm not going to use just to get route's function. 49 00:03:08,190 --> 00:03:13,920 Instead, we'll take advantage of that test main function that we used in our other tests. 50 00:03:14,700 --> 00:03:19,980 So I'll create a function called Test Me, which is what it has to be called in this instance, because 51 00:03:20,010 --> 00:03:24,420 this is part of the testing package available to us in the standard library. 52 00:03:24,810 --> 00:03:31,650 And it takes one parameter, which I'll call em, and it's a type testing program and it doesn't return 53 00:03:31,650 --> 00:03:32,010 anything. 54 00:03:32,820 --> 00:03:38,070 And then I'll grab the things out of routes that really belong in that test main function anyway. 55 00:03:38,100 --> 00:03:41,310 And that's everything up to and including the renderers. 56 00:03:41,640 --> 00:03:45,750 So I'll cut them out of here, I'll paste them into here. 57 00:03:46,770 --> 00:03:54,120 And then, of course, we need to have that OCR exit and run the tests just before you die, before 58 00:03:54,120 --> 00:03:55,170 it exits running. 59 00:03:56,460 --> 00:03:57,720 So they should be OS. 60 00:04:00,210 --> 00:04:05,400 All right, so now we have a test main function, and it seems that I have an error here. 61 00:04:05,460 --> 00:04:06,930 Oh, yes, Godbolt Register. 62 00:04:08,500 --> 00:04:09,400 Let's just. 63 00:04:11,480 --> 00:04:16,460 Yeah, it doesn't have the it didn't do the import for us, so I'll just force it to do the ghab dot 64 00:04:16,490 --> 00:04:21,650 register that'll force it to reimported into our imports and the air should go away. 65 00:04:22,160 --> 00:04:22,720 And it does. 66 00:04:23,390 --> 00:04:26,360 So now I've functionally I've changed nothing. 67 00:04:26,360 --> 00:04:32,150 I've just made it run the the set up in a test main function and we still have this get route's which 68 00:04:32,150 --> 00:04:33,380 we may or may not use. 69 00:04:33,440 --> 00:04:34,970 We'll find out in a little while. 70 00:04:36,020 --> 00:04:41,570 So let's go back to our tests and see what we can do to make this test actually passed. 71 00:04:42,770 --> 00:04:47,180 So what I want to do, first of all, is look at the reservation handler itself. 72 00:04:47,180 --> 00:04:48,350 So let's go back to handlers. 73 00:04:48,710 --> 00:04:54,350 It's expecting to pull a model's reservation out of the session and start in this variable. 74 00:04:54,390 --> 00:04:58,730 OK, so we need to have a model reservation to put in the session. 75 00:04:58,760 --> 00:04:59,710 Well, we know how to do that. 76 00:04:59,720 --> 00:05:00,250 That's easy. 77 00:05:01,010 --> 00:05:03,290 Let's just create a new variable called reservation. 78 00:05:04,910 --> 00:05:12,170 It's going to be assigned the value of models DOT Reservation, and I'll put just enough information 79 00:05:12,170 --> 00:05:18,020 in this variable to be able to actually deal with it in the reservation function in our handlers. 80 00:05:18,260 --> 00:05:23,810 So we need a remedy and we'll just use one, which is the general's quarters. 81 00:05:24,260 --> 00:05:29,240 And we also need the room, which is of type models room. 82 00:05:29,900 --> 00:05:31,490 We need the name and the ID in that. 83 00:05:31,490 --> 00:05:36,020 So that's going to be of type models that room. 84 00:05:38,410 --> 00:05:47,470 And inside of that, we will populate its ID, which is one, and it's Ramnath, which is Generals' 85 00:05:48,430 --> 00:05:49,150 quarters. 86 00:05:51,240 --> 00:05:57,770 When you come there and I need a comma there, and this should be a colon, not a comma. 87 00:05:59,540 --> 00:06:03,540 So now we have a reservation variable and I we need to put that in the session somehow. 88 00:06:03,560 --> 00:06:04,570 So let's get a request. 89 00:06:04,580 --> 00:06:11,840 We know how to get a request, request and potentially an error, which I'll ignore or assign the value 90 00:06:11,840 --> 00:06:13,790 of a new request. 91 00:06:15,770 --> 00:06:21,230 And the method is going to be get just as just like it is in the roots and the euro will be the same 92 00:06:21,230 --> 00:06:22,340 one we used in the Ritz. 93 00:06:22,340 --> 00:06:26,200 Make the reservation and we'll pass an antibody. 94 00:06:27,350 --> 00:06:29,210 So that's not HIV test. 95 00:06:29,450 --> 00:06:31,150 We're going to use HTTP request. 96 00:06:31,200 --> 00:06:31,630 There we are. 97 00:06:31,910 --> 00:06:37,220 So now we have a request and we need to put that in to the request. 98 00:06:38,420 --> 00:06:45,860 We need to put our reservation variable as a special variable into the session of the request. 99 00:06:46,220 --> 00:06:48,570 And of course, you do that using the context. 100 00:06:48,950 --> 00:06:50,390 Now, how am I going to do that? 101 00:06:50,420 --> 00:06:57,260 What I'm going to do is create a new function down here, which I'll just call get and it will take 102 00:06:57,260 --> 00:07:07,550 a request, which is a pointer to an HTTP request, and it's going to return a context, context, context. 103 00:07:08,670 --> 00:07:15,350 So what we're going to do is essentially get a context, put our sectional variable in it and then store 104 00:07:15,350 --> 00:07:17,270 that in our request. 105 00:07:17,810 --> 00:07:25,160 In order to do that, the context has to have a particular value in there, a key, something that is 106 00:07:25,280 --> 00:07:28,350 that these our session package knows is the session. 107 00:07:28,820 --> 00:07:30,260 Fortunately, that's pretty easy to do. 108 00:07:30,560 --> 00:07:36,110 So what I'm going to do is in this function, I'm going to create a context and potentially an error 109 00:07:37,160 --> 00:07:43,280 by calling session load, which is built right into our section session package. 110 00:07:43,280 --> 00:07:45,680 And we've done this before session that load. 111 00:07:46,370 --> 00:07:55,220 It requires a context which will be from the request that we've just passed this request context and 112 00:07:55,220 --> 00:07:56,740 it requires a header. 113 00:07:56,990 --> 00:08:05,450 So what we're going to do is get a header from that context, from that request request, that header 114 00:08:05,870 --> 00:08:13,250 doget and the header key is exactly like this and it uppercase and lowercase matter in this, in this. 115 00:08:13,250 --> 00:08:16,160 I think we're going to do it that way just to be absolutely safe. 116 00:08:16,640 --> 00:08:17,570 We'll check for an error. 117 00:08:17,660 --> 00:08:21,410 If error is not equal to nil, we'll just log the error. 118 00:08:21,500 --> 00:08:27,590 So log error log print line the error. 119 00:08:27,900 --> 00:08:28,760 That's all we'll do there. 120 00:08:31,450 --> 00:08:38,650 And then we'll return the context, but this context, we actually know about the header excession, 121 00:08:38,650 --> 00:08:42,930 which we need in order to read, to read from or write to the session. 122 00:08:43,840 --> 00:08:49,540 So back in this function test repository reservation, we have our request now. 123 00:08:49,540 --> 00:08:55,810 We need to get our context into that request so we'll get a context like this is a sign the value of 124 00:08:55,810 --> 00:08:59,310 get context and will pass at the request we just made. 125 00:08:59,590 --> 00:09:04,810 So now we have a context that we can actually add to our request. 126 00:09:04,810 --> 00:09:07,870 And we do that the same way we did the last time we wrote this sort of test. 127 00:09:08,260 --> 00:09:13,230 Request is equal to request with context the context we just created. 128 00:09:14,470 --> 00:09:20,680 So now we have a request that knows about the extra session header, so now we can do something with 129 00:09:20,680 --> 00:09:20,830 it. 130 00:09:21,850 --> 00:09:24,310 So what's the next step? 131 00:09:24,310 --> 00:09:27,630 The next step is a little different, something you haven't seen yet. 132 00:09:27,670 --> 00:09:34,210 We're going to take advantage of something that's built into the testing package of goal called a new 133 00:09:34,210 --> 00:09:37,090 recorder, an HIV test, new recorder. 134 00:09:37,120 --> 00:09:43,180 So what I'm going to do is create a new variable called R for request recorder that's going to be assigned 135 00:09:43,180 --> 00:09:47,620 the value of HTP test Dort new recorder. 136 00:09:48,430 --> 00:09:50,470 And this is exactly what it sounds like. 137 00:09:50,560 --> 00:09:52,180 We can actually look at the description of it. 138 00:09:52,480 --> 00:09:57,630 A new recorder is it returns an initialized response recorder. 139 00:09:57,760 --> 00:10:03,250 So this is basically simulating what we get from the request response lifecycle. 140 00:10:03,700 --> 00:10:09,700 When someone fires up a Web browser, hits our Web site, gets to a handler, passes that request, 141 00:10:09,850 --> 00:10:14,020 gets a response writer and the response writer writes the response to the Web browser. 142 00:10:14,080 --> 00:10:19,000 This fakes that entire process or the part of it that we need for a recorder. 143 00:10:19,300 --> 00:10:21,220 So we have a response recorder here. 144 00:10:21,400 --> 00:10:22,390 We're not using it yet. 145 00:10:22,390 --> 00:10:28,060 So we have to what we're going to do now is put our reservation in the session. 146 00:10:28,420 --> 00:10:30,070 Session put. 147 00:10:31,430 --> 00:10:38,150 Just like we do in a in our actual handlers, but instead of using the context from our request, we're 148 00:10:38,150 --> 00:10:46,970 going to use the context we've built X name and reservation and pass in our reservation. 149 00:10:49,180 --> 00:10:55,720 So now we've added that reservation variable to find up here with all of these values to our context, 150 00:10:55,720 --> 00:10:57,760 we've put it in the session in effect. 151 00:10:58,480 --> 00:11:06,100 And what we want to do now is actually call our reservation function, which is a handler, while we 152 00:11:06,100 --> 00:11:09,100 can't call it directly unless we do something to it. 153 00:11:09,220 --> 00:11:17,110 I'm going to take that handler reservation and turn it into a handler function so I can do that really 154 00:11:17,110 --> 00:11:17,520 easily. 155 00:11:17,860 --> 00:11:25,720 So I'm going to say handler, which is going to be just a variable that is assigned the value of our 156 00:11:26,230 --> 00:11:27,130 reservation. 157 00:11:27,130 --> 00:11:36,190 But I'm going to cast it to an HDTV handler function, htp dot handler func and I'm just going to put 158 00:11:36,190 --> 00:11:38,100 in repo dot reservation. 159 00:11:39,610 --> 00:11:44,880 So what I've done now is take our reservation variable or function, which is right here. 160 00:11:45,580 --> 00:11:52,210 It takes a response writer and a pointer to a request, and I've turned it into a function that I can 161 00:11:52,210 --> 00:11:53,050 call directly. 162 00:11:53,080 --> 00:11:57,070 So let's go back to our handlers test and actually call that function. 163 00:11:57,580 --> 00:12:02,310 And we do that simply by saying handler dot serve HTP. 164 00:12:02,920 --> 00:12:11,320 And what I'm going to put in there for its function, for its request and response are our request recorder 165 00:12:11,350 --> 00:12:14,590 are sort of response recorder and request that we've built. 166 00:12:15,730 --> 00:12:19,360 So when I do that, I can actually call that directly. 167 00:12:19,360 --> 00:12:25,270 I'm actually calling Serve HTP on this, just as I call it, on all of our roots in the main function 168 00:12:25,270 --> 00:12:32,200 of our application, simply because I've built a request, put that sessional variable reservation into 169 00:12:32,200 --> 00:12:36,700 the session, cast my reservation handler into a handler func. 170 00:12:36,880 --> 00:12:45,490 Now it has served HTTP because that is one of the things that you this satisfies all the the functions 171 00:12:45,490 --> 00:12:49,300 necessary to become something that actually acts as a Web server. 172 00:12:49,690 --> 00:12:52,330 So I don't even need my roots for this test. 173 00:12:52,330 --> 00:12:54,120 So I don't never call get roots at all. 174 00:12:54,130 --> 00:13:02,020 Instead I'm building it manually, calling this directly by calling handler serve htp, passing it my 175 00:13:02,020 --> 00:13:08,120 response recorder and passing it my request, which has the necessary sessional information in it. 176 00:13:08,530 --> 00:13:17,920 So at this point I can actually see if this test passed by saying if my are my response recorder, if 177 00:13:17,920 --> 00:13:23,530 its code is equal to http dot status, ok. 178 00:13:25,100 --> 00:13:32,360 Then it's past if it's not true, so this should be a not equal, if it's not equal to true, then I 179 00:13:32,360 --> 00:13:34,460 fail my test teig error. 180 00:13:36,380 --> 00:13:44,960 And I'll use Şeref in this case, and I put my string in here, reservation handler returned. 181 00:13:46,200 --> 00:13:48,300 Wrong response, quote. 182 00:13:49,890 --> 00:14:00,360 Got percent, Dean wanted percent, Dean, and then I replaced those placeholders with got our code 183 00:14:01,110 --> 00:14:04,530 wanted HTP status, OK? 184 00:14:06,280 --> 00:14:09,530 OK, so this will probably work. 185 00:14:09,850 --> 00:14:10,510 Let's find out. 186 00:14:10,780 --> 00:14:16,870 Let's go back to our terminal, clear the screen and run the tests, go test. 187 00:14:19,430 --> 00:14:25,430 OK, it passed, let's make sure it's actually passing, let's change this back to an equal, this should 188 00:14:25,430 --> 00:14:25,770 fail. 189 00:14:25,790 --> 00:14:28,840 Now let's clear our screen, run the test again. 190 00:14:30,120 --> 00:14:35,970 And it failed, so now we have a means of putting something in the session and pulling something out 191 00:14:35,970 --> 00:14:36,640 of our session. 192 00:14:36,660 --> 00:14:37,740 And this is a good start. 193 00:14:38,070 --> 00:14:46,620 So what we'll do in the next lecture or two is begin to create tests for all of the all of the routes 194 00:14:46,620 --> 00:14:48,600 in our handlers that use the session. 195 00:14:49,110 --> 00:14:56,520 And then we'll improve those tests by changing our test database repo to respond differently based upon 196 00:14:56,520 --> 00:14:59,190 the kind of information we pass it in our tests. 197 00:14:59,190 --> 00:15:00,720 And we'll do that in the next few lectures.
