1 00:00:01,350 --> 00:00:07,260 So while I was writing the last remaining tests for our handlers package, I realized that there is 2 00:00:07,260 --> 00:00:13,530 one particular function availability, Jason, where you may not, in fact, have enough information 3 00:00:13,530 --> 00:00:14,430 to complete this one. 4 00:00:14,430 --> 00:00:15,390 So I'll get you started. 5 00:00:16,080 --> 00:00:21,030 So first of all, when you look at the function itself, you'll notice that I don't actually pass the 6 00:00:21,030 --> 00:00:24,270 form and I need to pass the form in order to write a test. 7 00:00:24,660 --> 00:00:29,940 So what I'm going to do is I just wrote this beforehand and I'm just going to paste it in and show you 8 00:00:29,940 --> 00:00:34,680 what I'm doing here, what I'm doing, first of all, saying calling pass form, which I told you is 9 00:00:34,680 --> 00:00:39,360 good practice and it's good practice because when you're testing things, for example, you actually 10 00:00:39,360 --> 00:00:41,170 have to have this or you can't test it. 11 00:00:41,610 --> 00:00:45,630 The function worked just fine without it in the actual application. 12 00:00:45,630 --> 00:00:48,180 But we need to write test, so I'm going to pass it. 13 00:00:48,300 --> 00:00:51,600 And all I do here is pass the form and then I check for an error. 14 00:00:51,600 --> 00:00:56,340 And if there's an error, I'm going to return, not a server error or anything like that. 15 00:00:56,530 --> 00:01:00,870 I'm actually going to return Jason and Jason that says it's false and populates the message. 16 00:01:00,870 --> 00:01:09,300 So I just construct a JSON response which is defined right in this application right here, put in the 17 00:01:09,300 --> 00:01:13,530 appropriate values and write that Jason back to the browser and then I keep going. 18 00:01:13,830 --> 00:01:18,210 And the other thing that I want to do here is I'm going to copy this little bit where I'm writing JSON 19 00:01:18,660 --> 00:01:20,880 as when I hit the database. 20 00:01:21,300 --> 00:01:25,410 I actually need to ensure that I'm not writing a server error because that's just going to, you know, 21 00:01:25,410 --> 00:01:26,550 cause grief for us. 22 00:01:26,730 --> 00:01:29,580 Instead, I'll return again JSON. 23 00:01:29,580 --> 00:01:31,740 But this time I'll change the message to. 24 00:01:36,080 --> 00:01:41,330 Error connecting to database, which is sufficient for my purposes right now. 25 00:01:41,840 --> 00:01:44,840 OK, so that's the change I made to the application itself. 26 00:01:45,110 --> 00:01:48,380 And then down here, I actually removed the error check. 27 00:01:48,410 --> 00:01:53,630 And that's on this one, because when you think about it, I'd get into a situation where I'm trying 28 00:01:53,630 --> 00:01:56,230 to create JSON and have an error. 29 00:01:56,240 --> 00:02:01,030 So I try to create JSON to send the fact that I have an error and it just is a never ending chain there. 30 00:02:01,310 --> 00:02:07,580 So all I've done is to look at the actual code and here I am manually constructing this JSON response. 31 00:02:07,580 --> 00:02:10,070 So I know it's always going to be correct. 32 00:02:10,460 --> 00:02:13,200 There is no situation where this will ever throw an error. 33 00:02:13,220 --> 00:02:14,990 So all I did here was remove the error. 34 00:02:14,990 --> 00:02:19,190 And I added a comment to this, which you'll see in the source code if you choose to download it from 35 00:02:19,190 --> 00:02:19,910 the next lecture. 36 00:02:20,600 --> 00:02:25,280 So now let's go back and get started writing this test, and I will just start writing it for you and 37 00:02:25,280 --> 00:02:26,550 let you finish it on your own. 38 00:02:27,530 --> 00:02:35,300 So I am going to put in a new function here, which I will call func test repository. 39 00:02:35,300 --> 00:02:37,970 And the one I want is availability JSON right there. 40 00:02:38,630 --> 00:02:41,290 So the very first thing I'm going to do is identify my first case. 41 00:02:41,300 --> 00:02:46,940 So what's my first case to first case is rooms are not available. 42 00:02:47,850 --> 00:02:54,950 OK, so all I need to do is create a request body and my request body will be named Recke Body. 43 00:02:55,670 --> 00:03:03,170 It's assign the value of some start date start equals 2050 and fire in the future 01 01. 44 00:03:08,350 --> 00:03:17,830 And then I will, as I've done before, append to that request body equals format, not a sprint F and 45 00:03:17,830 --> 00:03:23,680 then a placeholder that's a string and an ampersand and a placeholder that's a string. 46 00:03:24,010 --> 00:03:28,780 And my two values, the first one being request body, because I'm appending to this I'm actually building 47 00:03:28,780 --> 00:03:36,730 on this string and then I want to put an end equals 250 zero one zero two and then I need a remedy. 48 00:03:36,820 --> 00:03:45,250 So I will now append to that room ID and I will make that one. 49 00:03:45,880 --> 00:03:48,580 OK, so I've got my request body now. 50 00:03:48,580 --> 00:03:52,390 I need to actually create the request, so create a request. 51 00:03:54,220 --> 00:04:02,070 And we do that just like we did before, request and ignore the error or assign the value of HTTP request. 52 00:04:02,830 --> 00:04:06,550 The method is post because this is a handler that takes a post. 53 00:04:07,090 --> 00:04:16,630 The URL is search availability, Jason, and we put in the body of the request using strings dot new 54 00:04:16,630 --> 00:04:21,120 reader and we put in our string called record body. 55 00:04:21,850 --> 00:04:22,960 So now I have my request. 56 00:04:24,010 --> 00:04:25,110 What do I do with it next? 57 00:04:25,120 --> 00:04:29,110 Well, I get the contacts with the session, which I'm not using, but I'm going to I might at some 58 00:04:29,110 --> 00:04:30,260 point in the future, who knows. 59 00:04:30,280 --> 00:04:35,770 So get context with session and I put in I get it this way. 60 00:04:35,770 --> 00:04:40,180 Context is a sign the value of get context and my request. 61 00:04:40,930 --> 00:04:46,780 And then I append that request to put that that context back into my request. 62 00:04:46,960 --> 00:04:50,110 Request equals request with context. 63 00:04:50,380 --> 00:04:52,240 And I put in my context. 64 00:04:54,040 --> 00:04:55,420 All right, what do I do next? 65 00:04:55,660 --> 00:04:57,550 Set the request header. 66 00:04:57,940 --> 00:05:06,500 And if you recall, we do that by saying request dot header, dot set and we want to set oops, I don't 67 00:05:06,520 --> 00:05:09,100 want to do their set. 68 00:05:12,020 --> 00:05:21,430 Content type, and that is of type X dash w w w dash form, dash Eurail encoded. 69 00:05:23,300 --> 00:05:24,480 So I've set the header now. 70 00:05:25,190 --> 00:05:32,120 Next step, make our handler a handler function, make handler handler function. 71 00:05:33,140 --> 00:05:44,180 And we do that very easily by saying handler is assigned the value of handler htp handler func and the 72 00:05:44,180 --> 00:05:48,200 handler we want to call, which is repo dot availability. 73 00:05:48,560 --> 00:05:49,220 Try that again. 74 00:05:50,750 --> 00:05:51,900 Availability Jason. 75 00:05:53,180 --> 00:05:53,690 There it is. 76 00:05:53,760 --> 00:05:57,530 Now we have our handler and we make the request. 77 00:06:00,720 --> 00:06:10,310 To our handler, so I say handler serve HTP and we want a response recorder, which I haven't made yet, 78 00:06:10,320 --> 00:06:13,800 so I'll have to do that and a request. 79 00:06:14,280 --> 00:06:19,560 So let's get our response recorder, get a response recorder. 80 00:06:20,370 --> 00:06:24,900 Are is assigned the value of HTP test. 81 00:06:26,220 --> 00:06:26,840 New recorder. 82 00:06:29,970 --> 00:06:35,010 All right, so now we've made the request to our handler and here's the part where you really don't 83 00:06:35,010 --> 00:06:36,480 ah, you're not sure how to handle this. 84 00:06:36,510 --> 00:06:38,000 You may not be sure how to handle this. 85 00:06:38,010 --> 00:06:42,960 We have covered Jason way back earlier in the course when we were going through the basics of Goaland. 86 00:06:43,770 --> 00:06:49,790 But I need to get what the server is sending back to me and convert that into Jason. 87 00:06:49,800 --> 00:06:55,140 So what I'm going to do is create a new variable, Varg, which is Jason response, because that's the 88 00:06:55,140 --> 00:06:55,590 response. 89 00:06:55,590 --> 00:07:00,420 I'm getting it back in and I have access to that because I'm in the handler's package and then I need 90 00:07:00,420 --> 00:07:05,160 to get what's being handed back to me by the server and put that into Jason. 91 00:07:05,460 --> 00:07:11,310 So I will say error is assigned the value of just like we did at the beginning of the course. 92 00:07:11,310 --> 00:07:12,750 Jason Marshall. 93 00:07:13,800 --> 00:07:19,320 And my data in this case is the body that the response is sending back to me. 94 00:07:19,320 --> 00:07:24,390 So I need to convert that to a slice of bytes because that's what this this particular function needs. 95 00:07:24,870 --> 00:07:31,440 And all I do is call our body, which is the body of the response being sent to us by the test server 96 00:07:31,740 --> 00:07:33,060 and convert that to a string. 97 00:07:34,710 --> 00:07:42,990 And then I'm putting all of that into my variable that I just declared J and now I have let's see if 98 00:07:42,990 --> 00:07:43,560 I got this right. 99 00:07:43,560 --> 00:07:44,040 I did. 100 00:07:44,050 --> 00:07:45,270 I got a check for an error. 101 00:07:45,270 --> 00:07:50,190 So if error is not equal to nil, then I want to fail the test. 102 00:07:50,430 --> 00:08:00,870 Teig error failed to pass, Jason, so that should get you far enough that you can now complete the 103 00:08:00,870 --> 00:08:06,600 actual test you need to do, because you'll have the response from the server in this structure, in 104 00:08:06,600 --> 00:08:09,060 this struct J, which is of type Jason response. 105 00:08:09,060 --> 00:08:12,870 And you can actually look at the responses you're getting back from the server. 106 00:08:12,930 --> 00:08:15,840 So that should be enough to let you finish writing this test. 107 00:08:15,870 --> 00:08:18,650 The rest of them, you have everything you need at your disposal. 108 00:08:18,930 --> 00:08:19,620 So good luck.
