How to write unit tests for your plugin – Introducing the Piwik Platform
17 novembre 2014, par Thomas Steur — DevelopmentThis is the next post of our blog series where we introduce the capabilities of the Piwik platform (our previous post was How to verify user permissions). This time you’ll learn how to write unit tests in Piwik. For this tutorial you will need to have basic knowledge of PHP, PHPUnit and the Piwik platform.
When is a test a unit test ?
There are many different opinions on this and it can be sometimes hard to decide. At Piwik we consider a test as a unit test if only a single method or class is being tested and if a test does not have a dependency to the filesystem, web, config, database or to any other plugin.
If a test is slow it can be an indicator that it is not a unit test. “Slow” is of course a bit vague. We will cover how to write other type of tests, such as integration tests, in one of our next blog posts.
Getting started
In this post, we assume that you have already installed Piwik 2.9.0 or later via git, set up your development environment and created a plugin. If not, visit the Piwik Developer Zone where you’ll find the tutorial Setting up Piwik and other Guides that help you to develop a plugin.
Let’s create a unit test
We start by using the Piwik Console to create a new unit test :
./console generate:test --testtype unitThe command will ask you to enter the name of the plugin the created test should belong to. I will use the plugin name “Insights”. Next it will ask you for the name of the test. Here you usually enter the name of the class you want to test. I will use “Widgets” in this example. There should now be a file
plugins/Insights/tests/Unit/WidgetsTest.phpwhich contains already an example to get you started easily :- /**
- * @group Insights
- * @group WidgetsTest
- * @group Plugins
- */
- class WidgetsTest extends \PHPUnit_Framework_TestCase
- {
- public function testSimpleAddition()
- {
- $this->assertEquals(2, 1+1);
- }
- }
We don’t want to cover how you should write your unit test. This is totally up to you. If you have no experience in writing unit tests yet, we recommend to read articles on the topic, or a book, or to watch videos or anything else that will help you learn best.
Running a test
To run a test we will use the command
tests:runwhich allows you to execute a test suite, a specific file or a group of tests.To verify whether the created test works we will run it as follows :
./console tests:run WidgetsTestThis will run all tests having the group
WidgetsTest. As other tests can use the same group you might want to pass the path to your test file instead :./console tests:run plugins/Insights/tests/Unit/Widgets.phpIf you want to run all tests within your plugin pass the name of your plugin as an argument :
./console tests:run insightsOf course you can also define multiple arguments :
./console tests:run insights WidgetsTestThis will execute all tests within the insights plugin having the group WidgetsTest. If you only want to run unit tests within your plugin you can do the following :
./console tests:run insights unitAdvanced features
Isn’t it easy to create a unit test ? We never even created a file ! You can accomplish even more if you want : You can generate other type of tests, you can run tests on Amazon’s AWS and more. Unfortunately, not everything is documented yet so we recommend to discover more features by executing the commands
./console list testsand./console help tests:run.If you have any feedback regarding our APIs or our guides in the Developer Zone feel free to send it to us.

Can't find a good solution to play a MPEG2-TS (no HLS) stream on my iOS App
29 octobre 2019, par Heidan34I’m currently looking for an easy to implement iOS media player library that can cover my needs which are :
-
Being able to play a MPEG2-TS (.ts) without hls.
-
Being able to authenticate the video request with a bearer in the header
I tried some without success, most of the other ones were not maintained anymore :
- AVPlayer (native)
- SGPlayer
- VLCKit (video ok but crashes randomly + not able to give a custom http header)
- ffmpeg-avplayer
Could you please help me ?
Thanks !

Could not find tag for codec h264 in stream #0 (mp4)
18 août 2019, par TabsNotSpacesI’ve been using the sickbeard_mp4_converter for a while to convert video files to mp4 by generating a script for ffmpeg. I’m not sure what I changed, but the ffmpeg script it generates no longer works and I’m having trouble debugging it. Can anyone tell from my log what the issue is ? Yes, its supposed to be an mp4 to an mp4, which is typically fine.
I’m at the point where I’m using an mp4 that worked with the same autogenerated script yesterday but it no longer is. I remember updating ffmpeg but downgrading did not resolve the issue, though I may have not downgraded enough.
ffmpeg 4.1.4
