UMD Quality Criteria
All the software included in the Universal Middleware Distribution (UMD) must meet a set of Quality Criteria defined by EGI. The Quality Criteria can be classified into generic criteria, i.e. criteria which sould hold for any component of the UMD, and specific criteria, i.e. criteria valid for a particular component only.
In order to be verified, quality criteria is specified as a set of tests. Those tests must ensure the correctness, completeness and security of each service. Software providers must include with each component a complete test plan that covers all the quality criteria. The test plan is composed by:
- Documentation on how to run the tests.
- A test suite for each of the generic criteria.
- A test suite for each of the specific criteria applicable to the component.
- Tests results for all the specified tests.
In the case of revision releases, the test plan must include specific tests for the bugs fixed in the release.
Generic acceptance criteria
Services in UMD must include a comprehensive documentation written in a uniform and clear style, which reflects all of the following items:
- Functional description of the software.
- User documentation, including complete man pages of the commands and user guides.
- Complete API documentation (if there is an API)
- Administrator documentation that includes the installation procedure; detailed configuration of service; starting, stopping and querying service procedures; ports (or port ranges) used and expected connections to those ports; cron jobs needed for the service)
- List of processes that are expected to run, giving a typical load of the service. List of how state information is managed and debugging information (e.g.: list of log files, any files or databases containing service information).
- Notes on the testing procedure and expected tests results.
Verification: existence of the documentation with all the required items.
Source Code Quality and Availability
The source code of each component of the UMD middleware should follow a coherent and clear programming style that helps in the readability of the code and eases maintenance, testing, debugging, fixing, modification and portability of the software. Open source components must publicly offer their source code and the license with the binaries.
Verification: for Open Source components, availability of the code and license. Source code quality metrics are desirable.
Management, Monitoring, Traceability
All the services must include tools related to:
- Starting, stopping, suspending, listing and querying the status of all the service daemons.
- Checking the responsiveness of all the service components or daemons
- Checking the correctness of the service components behavior (expected actions after a request are taken)
- Tracing all the user actions in the system (e.g. by generating logs)
Ideally, these tools should be also available remotely, allowing operators to react timely to problems in the infrastructure. A uniform interface for remote management and monitoring should be followed by all the services. Monitorization should also be easily used in existing monitoring systems such as Nagios.
Verification: Test suite with tests to:
- start, stop, suspend, and query status of service
- check responsiveness of service (expected ports open and expected answer to commands received)
- check correctness of service behavior (expexted actions after a request are taken)
- track of user actions in the system (generation of logs and accounting information)
Tools for the automatic or semi-automatic configuration of the services must be provided with the software. These tools should allow the unassisted configuration of the services for the most common use cases while being customizable for advanced user. Complete manual configuration must be always allowed.
Verification: test suite must include the configuration mechanisms and tools. Yaim is considered as the preferred tool.
