Travis CI

Travis CI is a continuous integration platform for GitHub. If you run your PHPUnit tests on Travis, read on to learn more about how to configure it.

First, you need to store the Blackfire client and server credentials so that Travis has access to them when running Blackfire related tests. By convention, store them in a .blackfire.travis.ini file that you won't commit in your repository:

; .blackfire.travis.ini
[blackfire]

server-id=<BLACKFIRE_SERVER_ID>
server-token=<BLACKFIRE_SERVER_TOKEN>
client-id=<BLACKFIRE_CLIENT_ID>
client-token=<BLACKFIRE_CLIENT_TOKEN>
endpoint=https://blackfire.io/
collector=https://blackfire.io/

Replace the placeholders above with your client and server credentials:

Then, encrypt the file and commit the encrypted file (.blackfire.travis.ini.enc) to the GitHub repository (replace organization/project with your GitHub repository name):

1
travis encrypt-file .blackfire.travis.ini -r organization/project

Note that Travis does not allow the decryption of encrypted files on GitHub forks, which means that pull requests tests won't have access to the Blackfire configuration unless they come from the main repository.

Finally, update your .travis.yml file to install Blackfire and run the agent before running the tests according to the following template:

Please update $encrypted_16ab3ffdcd52_key and $encrypted_16ab3ffdcd52_iv with the results of travis encrypt-file.

To get more accurate results with Blackfire, we highly recommend to disable XDebug:
