.gitlab-ci.yml

-# # GitLab CI Jobs
+# # GitLab CI Job Configuration
 #
-# Each of the jobs defined here is triggered by GitLab's CI pipeline.
-#
-# ## GitLab YAML Job Description Syntax
+# Goal: Run all jobs defined here on all available runners (GNU/Linux and
+# Windows).
+# 
+# ## Job Description Syntax
 #
 # <job_name>:                   # Job name which is displayed in web interface.
-#   stage: <stage_name>         # <build|test|deploy>: these stages are executed
-#                               # one after another. A stage can contain multiple
-#                               # jobs.
+#   stage: <stage_name>         # Run "script" commands in this stage. The
+#                               # stages are exececuted sequentially.
 #   script:
 #      - <arbitrary_commands>   # Here you can execute arbitratry terminal
 #                               # commands. If any of the commands return a
 #                               # non-zero exit code, the job fails.
 #
-# ## Maven Syntax for Skipping Unit Tests
-#
-# General syntax to execute unit tests:
-#
-# ```
-# mvn test
-# ```
-#
-# The comma-separated list of tests after "-Dtest=<list>" is skipped. All other
-# tests are executed normally:
+# ## References
 #
-# ```
-# mvn -Dtest=!TestClassA,!TestClassB,!TestClassC
-# ```
-#
-# **Note:** on some CI instances the exclamation mark must be escaped by a
-# backslash. Otherwise, it is interpreted by the executing shell as special
-# command.
-#
-# ## Unit Test Limitations
-#
-# **Watch out:** OpenCL code cannot be run on virtual machines where tests are
-# executed. Therefore, skip this tests.
