Background

Gendarme is a static analysis tool to find problems in .NET software. Gendarme inspects executables and libraries that contain code in ECMA CIL format (Mono and .NET) and looks for common problems with the code, problems that compiler do not typically check or have not historically checked.

Task

The task is to write one Gendarme rule that at least one method in a non-abstract type implementing IRule is calling one of the Runner.Report overrides. The rule could be named 'DefectsMustBeReportedRule'.

Since this is a special rule it needs to be located in a new assembly, e.g. Gendarme.Rules.Gendarme.dll, and ensure that Gendarme.Framework.dll is referenced by the assembly being analyzed (otherwise the rule must turn itself off). This last step should be in a separate abstract rule so it can be reused for other, future, rules about Gendarme.

Also please note the extra requirement to provide a patch to fix all such issues (if any) found inside Gendarme rules.

Deliverables

To complete the task the student must provide:

*  the rules, written in C#. The source code must follow the Mono source code guidelines (available at http://www.mono-project.com/Coding_Guidelines). Also a 'self-check' must be done one the code (i.e. you need to run gendarme on your own code) and the defects, if any, must be fixed (in doubt please ask for guidance on IRC).

* its documentation (in-source xmldoc) that includes 'good' and 'bad' examples; and

* the unit tests (also in C# using the gendarme helpers around NUnit) proving the rule is working as intended

* a patch to fix all such issues (if any) in Gendarme rules

Once ready the files (or the patch) can be submitted to the mentor for review.

Hints

* In order to avoid misunderstandings you should start by writing your unit tests and ask for a review of them. That will quickly tell you if you're on the right path to solve the problem.

* Gendarme provides hundreds of rules that can be used as example, here's one

rule: https://github.com/mono/mono-tools/blob/master/gendarme/rules/Gendarme.Rules.Interoperability/PInvokeShouldNotBeVisibleRule.cs

tests: https://github.com/mono/mono-tools/blob/master/gendarme/rules/Gendarme.Rules.Interoperability/Test/PInvokeShouldNotBeVisibleTest.cs
