I have been using bitbucket for quite sometime, and really like their service. Recently, I come to know that they have Beta of CI through pipeline, that can run any docker from Docker hub. I thought to give it a try though I have my own build setup on my local machine and really don’t need it. But why not test something new.

So, my project is regular website, which is coded in Custom PHP (no framework) and using MySQL database. I wrote some Unit Test using PHPUnit test, so all I need is to run those test when I commit to Bitbucket. It seems pretty straight forward as Bitbucket configuration example shows the configuration file for PHPUnit test. I pick it up, change path and run. My test failed, as they never get the MySQL extension for PHP. What? PHPunit test docker doesn’t have database extension installed? So, how we are suppose to test it?

Well, there are few ways, one is you use multiple docker (multi-docker environment) which I recently studied is available and I didn’t yet test it. And other is you create your own docker and use it. Install whatever you need to make it happen. Also, I realize that installing MySQL will not make any good unless I install database on it before test and change it’s certain values for testing. So, I create a new docker that has everything I need for my project, all PHP extension and database server. (You can use it from https://hub.docker.com/r/archergod/phpall/). Then I update configuration file to do following:

1. Run MySQL service (yes by default docker do not initiate run.d etc, not sure why) and hence no service auto start.
2. Then run `mysql` to import a Script (SQL) file to create and install database, and users needed. I put everything in that one SQL file and run it as root MySQL user. It is only a docker doing testing.
3. then Navigate to Directory in respect to my Git folder as my default bitbucket leave your prompt at git folder.
4. Run your test.

It does a great work, though every time you push to git, it create a CI request and download docker image, set it up based on BitBucket’s script and then run your script. So it take 2 minute extra to set the machine. If you are in habbit to push every 2 hr of work, then you end up running your test every 2 hr on every push.

But basically it is all good and is free too, which I like most. Though I have GitLab at my local machine and it works exceptionally great, but BitBucket’s CI is good and different. And in some cases is better than Gitlab’s CI.
