WEBVTT 00:02.000 --> 00:08.320 Right now we are using git for version control, and we have also added end to end tests to ensure that 00:08.320 --> 00:10.320 the application is working properly. 00:10.320 --> 00:12.720 So let's put everything to a test. 00:12.880 --> 00:19.880 I'm going to ask the agent to purposefully introduce a bug that will break this application, and this 00:19.880 --> 00:24.720 will allow us to run the end to end test and to ensure that they actually fail if there's something 00:24.720 --> 00:25.880 wrong with the application. 00:26.160 --> 00:33.240 And apart from this, what we also want to do is to revert the changes that are happening right now, 00:33.400 --> 00:39.560 just to make sure that in case something bad happens, we know how to revert to a previously working 00:39.560 --> 00:40.160 version. 00:40.840 --> 00:43.520 So it's saying here I've added a bug. 00:43.520 --> 00:45.000 So let's go ahead and test it out. 00:46.200 --> 00:49.000 And I go back to the categories back to home. 00:49.320 --> 00:53.760 And currently you know the home page is not displaying anything. 00:53.760 --> 00:56.000 So everything has disappeared from the home page. 00:57.160 --> 00:57.440 Okay. 00:57.480 --> 00:59.720 So let's go ahead and run the end to end test. 01:00.980 --> 01:06.220 So now what we're going to see here is also the end to end tests failing. 01:06.460 --> 01:09.540 And I click here skip and continue. 01:10.140 --> 01:15.140 And we're going to get here the HTML report in a different window. 01:15.620 --> 01:17.300 We don't really care about this so much. 01:17.300 --> 01:19.220 So it's absolutely fine for us. 01:20.100 --> 01:24.340 But it's explained here as expected the end to end test fail. 01:25.060 --> 01:25.700 All right. 01:25.700 --> 01:31.300 So in this case we have tested that there's something that doesn't work properly. 01:32.220 --> 01:34.100 Let's see exactly what's happening next. 01:34.620 --> 01:38.780 So it has now fixed the bug by reverting the root path okay. 01:38.940 --> 01:40.260 That's very very nice. 01:40.620 --> 01:44.540 I wanted it to not make any changes altogether. 01:44.540 --> 01:48.140 So this should have allowed us to figure out how to revert these changes altogether. 01:48.380 --> 01:52.780 So I'm going to ask again to introduce a bug that is breaking the application. 01:53.420 --> 01:56.620 So this time it has introduced a different bug. 01:56.820 --> 02:00.020 Of course it would be very nice to manually test it. 02:00.020 --> 02:04.800 tested, run the end to end test to make sure that this bug is indeed as it appears here. 02:06.000 --> 02:08.280 So we see here the flash cards. 02:08.280 --> 02:12.160 We're entering animals, and now the flash card doesn't appear. 02:12.440 --> 02:13.720 So definitely a bug. 02:13.760 --> 02:15.040 Now what can we do? 02:15.240 --> 02:18.440 Well, first of all we could click here on reject. 02:19.040 --> 02:21.360 So that is definitely one option. 02:21.600 --> 02:25.320 We go through the cursor route reject those changes. 02:25.320 --> 02:28.120 And we're going to get back the version that we have. 02:28.560 --> 02:33.480 This particular changes are also available here in Source Components flash card. 02:33.720 --> 02:36.560 And you can see here exactly what has changed. 02:36.560 --> 02:37.800 So this is a comment here. 02:37.800 --> 02:39.240 And we can accept or reject it. 02:39.240 --> 02:44.320 So we can see even at the file level and also at the line level what has changed. 02:44.760 --> 02:45.960 Option number one. 02:46.440 --> 02:52.040 The second option that we have is we have this graphical user interface integration. 02:52.040 --> 02:55.960 If you click on this particular button you're going to see here which changes have been made. 02:55.960 --> 03:01.620 So if you click here on flash card we're going to see here the changes that have been made, and we 03:01.620 --> 03:04.140 can simply click on this button here. 03:04.140 --> 03:08.700 This card changes and if you click on this, this change will go away. 03:08.980 --> 03:11.740 The application will work again just as before. 03:12.420 --> 03:18.980 And third option is to simply ask the agent to discard any changes. 03:18.980 --> 03:25.860 So you can see here discard any changes that are multiple ways on how we can go back to a previously 03:25.860 --> 03:26.940 working version. 03:27.540 --> 03:31.380 And in this case it's going to restore the last commit. 03:31.540 --> 03:36.020 These changes are going to disappear and the application itself should be working again. 03:36.020 --> 03:39.580 So you're going to see here it's working without any issues. 03:39.740 --> 03:45.260 So this is how we can roll back to a specific version in this case to a previous version. 03:45.260 --> 03:49.380 We also have a list of all the commits and all the changes that we made so far. 03:49.540 --> 03:55.540 We can also revert to a specific version if we want to do so, and we can do this relatively easily 03:55.540 --> 03:57.420 by talking directly to the agent.
