This cookbook prepare virtual machine for Automated Exploratory Tests (AET).

It may be used to quickly create platform for AET demo or to setup an environment for AET development. Required artifacts are downloaded by this cookbook from AET GitHub releases page.

Because this cookbook is used for demo instances or development platforms we are not supporting a wide range of platforms. CentOS release 6.8 (Final) is supported currently.

For demo instance default recipe should be used. For development purpose use aet::_develop and aet::default recipes. The aet::_develop recipe provides additional user used by Maven to upload AET artifacts.

Include aet in your node's run_list:

{
  "run_list": [
    "recipe[aet::_develop]",
    "recipe[aet::default]"
  ]
}

After you have AET instance up and running you could prepare a Maven project to run AET tests. Please refer to the AET documentation on how to setup a test suite.

The cookbook installs following components required by AET:

• Karaf framework (ver 4.2.0) - OSGi environment for AET bundles
• Active MQ (ver. 5.15.2) - for communication between AET components
• Mongo DB - for storing tests results
• Apache HTTP server - for AET reports Web Application
• Browsermob (ver. 2.1.4) - proxy for collecting additional browsing data
• XVFB - for running firefox in virtual screen
• Firefox (ver. 38.6.0esr) - for collecting screenshots of pages and other data
• Tomcat (ver. 8.0.36) - for serving sample site that is used by maintenance tests
• Selenium Grid (ver. 3.14.0) - for handling tests on different browsers

Those components may be installed on separate machines provided they have been configured to work with each other. The configuration is done within Karaf Web Console.

• Karaf - Karaf Web Console should be available at http://192.168.123.100:8181/system/console/bundles. Default credentials: karaf/karaf.
• Active MQ - Active MQ Web Console should be available at http://192.168.123.100:8161 Default credentials: admin/admin.
• Mongo DB - curl -I 192.168.123.100:27017 responding with Empty response means that Mongo is listening on default port.
• Apache HTTP Server - could be checked with curl -I 192.168.123.100
• Tomcat - could be checked with curl -I 192.168.123.100:9090
• Selenium Grid - Selenium Grid Hub should be available at http://192.168.123.100:4444/grid/console. Selenium Grid nodes should be listed there as well.
• Browsermob - try curl -I 192.168.123.100:8080. Expected response is:

HTTP/1.1 404 Not Found
Cache-Control: must-revalidate,no-cache,no-store
Content-Type: text/html;charset=ISO-8859-1
Content-Length: 1267
Server: Jetty(7.3.0.v20110203)

Recipes below are presented in groups. Each group (except common) should be installed on same system.

• java::default - Installs Open JDK 8 required by other AET components. Uses JAVA cookbook, so the JAVA version might be changed with that cookbook properties.

Recipes:

• aet::activemq - creates dedicated user (configured with node['aet']['activemq']['user'] and node['aet']['activemq']['group']), downloads and install binary distribution of Active MQ (using binary package from node['aet']['activemq']['source']). Registers Active MQ as a service (/etc/init.d/activemq).

Recipes:

• aet::apache - Uses Apache cookbook. Installs Apache HTTP server. Additionally creates a folder (node['aet']['apache']['log_dir']) for apache logs and creates a link from /var/log/httpd to that folder. Enables proxy, proxy_http and headers modules. If aet::_develop recipe is used, then apache service is run with develop system user.
• aet::deploy_reports - checks if node['aet']['version'] is currently linked as current folder. If no then downloads that version of AET reports web application and extract it into node['aet']['apache']['report_base_dir']/aet_reports/#{ver}. Creates a link from node['aet']['apache']['report_base_dir']/aet_reports/current to the version folder. Setup virtual host for serving a content from the current folder. If aet::_develop recipe is used this is done with develop user.

Recipes:

• aet::karaf - Creates dedicated system user for Karaf service. If aet::_develop recipe is used, then this user is overwritten by develop user. Downloads Karaf and extracts it into node['aet']['karaf']['root_dir']. Creates a symbolic link from node['aet']['karaf']['root_dir']/current to extracted Karaf instance. Sets the Web Console credentials in users.properties file and HTTP port in org.ops4j.pax.web.cfg file). Creates symbolic link from Karaf log dir to node['aet']['karaf']['log_dir']. Registers Karaf as a service (/etc/init.d/karaf) and starts it.
• aet::deploy_aet_for_karaf - Deploys AET artifacts for Karaf. This is done only for new installation or when version is changed for AET. New artifacts are downloaded and extracted. Then link with the name of 'current' is created that points to the new version folder. Then Karaf restart is scheduled. If aet::_develop recipe is used this is done with develop user.
• aet::postdeploy_restart - Check if karaf restart was scheduled (if /tmp/karaf-restart file exists). If so, then stops Karaf service, deletes Karaf cache folders and starts Karaf again.
• aet::browsermob - Creates dedicated user for Browsermob service. Installs Browsermob into node['aet']['browsermob']['root_dir']. Registers it as a service (/etc/init.d/browsermob) and starts it.
• aet::firefox - Creates dedicated user for firefox folders permissions. Downloads (from node['aet']['firefox']['source']) and installs Firefox browser. Configures Firefox to use virtual display from XVFB.
• aet::xvfb - Creates dedicated user for xvfb. Installs XVFB service and configures it to use node['aet']['xvfb']['log_dir'] as log dir. The resolution for virtual screen may be set by node['aet']['xvfb']['resolution']. The default value is '1280x1024x24'.

Recipes:

• aet::tomcat - Creates dedicated user for Tomcat service. If aet::_develop recipe is used, then this user is overwritten by develop user. Downloads tomcat and installs it into node['aet']['tomcat']['base_dir']. Configures JAVA settings, tomcat port and tomcat users. Registers tomcat as a service (/etc/init.d/tomcat) and enables it.
• aet::deploy_sample_site - Checks if node['aet']['karaf']['root_dir']/tomcat/aet_sample_site/current is a link to current version (node['aet']['version']) of sample site. If not, then downloads required version, extracts it to node['aet']['karaf']['root_dir']/tomcat/aet_sample_site/#{ver}, creates a link from current to this version and restarts tomcat. If aet::_develop recipe is used this is done with develop user.

• aet::seleniumgrid_hub - Creates dedicated user for Selenium Grid service. If aet::_develop recipe is used, then this user is overwritten by develop user. Downloads selenium standalone server and installs hub into node['aet']['selenium']['hub']['root_dir']. Registers seleniumgrid-hub as a service (/etc/init.d/hub), enables and starts it.

• aet::seleniumgrid_node_ff - Creates dedicated user for Selenium Grid service. If aet::_develop recipe is used, then this user is overwritten by develop user. Downloads selenium standalone server and installs Selenium node in node['aet']['selenium']['node_ff']['root_dir']. Uses existing Firefox browser /usr/bin/firefox without gecko driver ("marionette" set to false). Registers node-ff as a service (/etc/init.d/node-ff), enables and starts it.

• aet::_develop - Please note that this recipe is not included by default. If included it will override system users for Tomcat, Karaf and Apache with develop user. This has been done in order to enable uploads of AET artifacts to these services.

Recipes:

• aet::mongo - Installs Mongo DB with MongoDB cookbook

Recipes:

• aet::display - Installs X Window for the convenience of virtual machine users.
• aet::reboot - After X Window is installed the system needs one reboot. This cookbook schedules reboot of virtual machine. The reboot is done only once.

kitchen verify karaf-centos-68

To run all existing tests you cun use this command:

Deployment of new versions of this cookbook is managed with Stove. For Ruby on windows you can use Ruby Installer. Chef Supermarket login and key is required for new version deployment.

New version needs to be numeric in form of X.Y or X.Y.Z.

Inside the aet-cookbook install bundler:

gem install bundle

Then install gems required by stove (which is already added to Gemfile):

bundle install

Configure your Chef credentials (see stove configuration)

1. Update metadata.rb file to contain the version that should be released (Cookbook Versioning Policy).
2. Update CHANGELOG.md file: provide version number for unreleased changes.
3. Commit and push changes. Create a GIT tag with version number i.e. v3.1.0.

To send the current version of cookbook to Chef supermarket run

stove --no-git --username <your username> --key <path to chef private key>

After cookbook deployment update metadata.rb and CHANGELOG.md files for new development lifecycle.
